How to Use the Laser System
Laser
Powering the Laser
Batteries
Depending on the laser system configuration that you purchase, the laser is
shipped with either rechargeable nickel-cadmium (Ni-Cd) or nickel/metal-
hydride (Ni-MH) batteries. Even if you buy a laser that uses Ni-Cd batteries,
you can upgrade to Ni-MH batteries. The upgrade installation, however, must
be performed by an authorized service center.
Alkaline batteries can also be used as a backup; however, rechargeable
batteries should be reinstalled in the laser as soon as possible.
To let you know when the batteries are getting low, the status LED flashes.
When the status LED flashes yellow, the laser has less than one hour of
running time. When the status LED remains on solid yellow, the batteries
have less than five minutes running time.
After shipment, the batteries may not have enough power to operate the
system. Be sure to recharge the batteries before use. The intelligent recharger
maximizes battery life and reduces the time before battery replacement by
precisely controlling the recharging/discharging cycle and by not
overcharging the batteries. The maximum time to achieve a full charge is six
hours.
Recharging the Batteries
Note: Do not recharge alkaline batteries. Trying to recharge them does not
damage the laser but the batteries do not recharge.
1. Plug the 4-socket plug into the laser and tighten the retaining collar.
2. Plug the supplied grounded electrical power cord into the battery-
recharger.
3. Plug the grounded electrical power cord into an appropriate outlet.
Note: The recharging status is indicated on the recharger.
Left LED Right LED Recharging Status
Off Off No connection or no batteries
Off On Recharging is in progress
Flashing Off Recharging is complete
Flashing Flashing Recharging error
Note: The laser will not operate while the batteries are recharging.
Note: Some countries or local areas have regulations regarding the disposal
of rechargeable batteries. Please be sure to follow the regulation in your area.
Installing/Removing the Batteries
CAUTION: The batteries should be removed when storing the laser more
than 30 days.
1. Remove the four screws from the battery housing. Remove the battery-
housing compartment.
2. Install/remove the batteries.
Note: When installing the batteries, be sure to note the positive (+) and
negative (-) diagram inside of the housing.
Note: The laser has reverse polarity protection. If the batteries are put in
wrong, no damage occurs to the laser but it does not work. Allow it one
minute to recover after the batteries have been installed correctly.
3. Put the battery-housing compartment in place and reinstall the four
screws.
External Power Cable
The laser system also includes an external power cable so you can operate
the laser in case the internal batteries become discharged. The internal
batteries will not recharge, however, while you’re using the external power
cable.
Connecting/Disconnecting the External Power Cable
CAUTION: To avoid damaging the laser, make sure the laser is off before
connecting/disconnecting the external power cable to/from the laser.
1. Connect the alligator clips to a 12-V dc automotive or motorcycle
battery noting the correct polarity (red = positive, black = negative).
2. Plug the 4-socket plug into the laser and tighten the retaining collar.
3. To disconnect the external power cable from the laser, loosen the
retaining collar, unplug the 4-socket plug from the laser, and remove the
alligator clips from the battery.
Learning Basic Laser Functions
Turning On/Off the Laser
1. Press the power button to turn on the laser.
Note: The laser always powers up in the automatic self-leveling mode. If the
laser is out of its self-leveling range and remains out of it for more than 30
minutes, the laser shuts down completely.
Note: When the laser is initially turned on, the LCD shows the approximate
charge of the batteries, the laser beam’s rotation speed, and manual axis-
alignment position if it’s other than zero. After the LCD shows this
information, the last-entered grade immediately appears in the LCD. The
status LED flashes green to indicate that the laser is self-leveling. After the
laser has self-leveled at the indicated grade, the laser beam rotates and the
status LED stops flashing.
Note: After the laser has been level for more than 30 minutes, the HI alert
activates. If the laser is disturbed (tripod bumped, etc.) so that when it re-
levels the laser beam elevation changes by more than 1/8 in. (3.1 mm), the HI
alert shuts down the laser and rotor, and the status LED flashes red two times
per second (twice the manual-mode rate).
2. To turn off the laser, press and hold the power button for three seconds.
Selecting the Rotation Speed
The laser has three laser beam rotation speeds—300, 600, and 900 rpm. The
rotation speed can be changed at any time to meet your job-site conditions.
Use 600 rpm for held-held receivers and most machine-control systems.
1. Repeatedly press and release the rotation-control button until the desired
rotation speed appears in the LCD.
Note: The selected rotation speed briefly appears in the LCD. After a few
seconds, the selected percentage of grade appears in the LCD.
Changing the Grade Value
The grade value for both axes can be changed using two methods—standard
and quick-change. The standard method is used for entering small changes in
the grade value. The quick-change method is used for setting grade to zero
and entering large changes in the grade value.
Standard Method
Note: The grade value can be quickly set to 0.000% by simultaneously
pressing and releasing the up and down buttons for the axis you want to
change.
1. Press and hold the up or down button for the axis you want to change
until the correct grade value appears in the laser’s LCD.
Note: The speed of the grade value change increases with the amount of time
the button is held down.
Note: Grade values from -0.500 to 9.999% are displayed in thousandths of a
percents. Grade values greater than 10% are displayed in hundredths of a
percent.
Note: All changes to the axis-alignment rotation made prior to changing the
grade value using the standard method are retained.
Quick-Change Method
Note: The grade value can be quickly set to 0.000% by simultaneously
pressing and holding the up and down buttons for the axis you want to
change
1. Simultaneously press and hold the up and down buttons for the axis you
want to change to set the grade value to 0.000%.
Note: The grade value for the ∠ axis increases in 1.00% increments. The
grade value for the ∠ axis increases in 5.00% increments.
2. Continue pressing and holding the up and down buttons until the correct
grade value appears in the laser’s LCD.
Note: When the grade value for either axis reaches its highest amount, the
grade value switches to the lowest value for that axis. In the ∠ axis, for
example, the value switches from +10.00% to –10.00%. In the ∠ axis, the
value switches from 25.00% to -0.500%. For steep-grade lasers, the value
switches from 110.00% to -0.500%.
Note: All changes to the axis-alignment rotation made prior to changing the
grade value using the quick-change method are cancelled.
Activating/Deactivating Manual Mode
Manual mode bypasses the laser’s automatic self-leveling mode so you can
use the laser in vertical mode. Manual mode also allows you to tilt the laser
beyond its built-in sloping capability so you can perform steep-sloping
horizontal applications.
1. Make sure the laser is on and in the orientation appropriate for your
application needs (horizontal or vertical).
2. Press the manual mode button.
Note: When manual mode is activated, the status LED flashes red once per
second and scrolling horizontal segments appear in the LCD.
3. To resume automatic self-leveling mode, press the manual button again.
Rotating the Axis Alignment Manually
The axes-alignment buttons allow you to electronically rotate the laser so that
the grade of the laser beam properly aligns to the job-site grade.
1. To make coarse adjustments, look through the sighting guides on top of
the laser and turn the laser on the tripod until it is properly aligned.
2. To make fine adjustments, press and hold the axis-alignment button that
corresponds to the direction you want to rotate the laser’s axis until the
desired rotation has been reached.
Note: A vertical line in the LCD moves to the left or right to give you a rough
indication of the rotation position.

Getting Connected
Laser
Connecting the Laser to a Tripod
All lasers have a 5/8-11 tripod mount on the bottom of the laser so you can
connect the laser to a standard tripod, column clamp, or other mounting
device. The laser can also be used without a tripod, but the laser must be set
on a stable surface.
In addition to using the laser in horizontal mode, you can use it in vertical
mode. To do so, however, an after-market vertical mounting bracket is
needed. For instruction on how to use the vertical mounting bracket, consult
the specific manufacturer’s instructions.
1. Insert the tripod’s 5/8-11 screw into the laser’s threaded 5/8-11 tripod
mount.
2. Turn the screw counterclockwise to hold the laser securely in place.
3. To detach the laser from the tripod, turn the screw clockwise.
Connecting the Laser to the Adapters
Depending on the laser system you purchase, additional mounting
accessories may be shipped with your laser. The long-range (agricultural)
laser system includes a quick-disconnect adapter and a 3 1/2-8 adapter. The
steep-grade laser system includes a steep-grade adapter and offset plate.
Quick-Disconnect and 3 1/2-8 Adapters
1. Thread the appropriate adapter into the 5/8-11 threaded mount on the
bottom of the laser.
Note: The carrying case is designed so the adapter can remain on the laser.

capability up to a maximum of ±40 degrees).
1. Set up the laser over a reference point. Make sure the laser is positioned
so that the ∠ and ∠ axes are pointing in the right direction.
2. Using the sighting guides as guide, rotate the laser on its tripod to align the
laser to the direction hub.
3. Connect a receiver to a grade rod and turn on the receiver. Make sure you
position the receiver so that it is at the correct elevation for the distance
(and grade) from the laser to the direction hub.
4. Set the grade rod on the direction hub.
Note: If only one person is manually aligning the laser, use a bipod
(commonly used with prism poles) to keep the grade rod plumb when
placing is on the direction hub.
5. Press the appropriate manual axis alignment button to align the laser plane
to the receiver. The clockwise axis alignment button rotates the laser
clockwise; the counterclockwise axis alignment button rotates the laser
counterclockwise.
6. Press and hold the axis alignment button until you get an on-grade reading
on the receiver.
Setting Up the Laser in Vertical Mode
1. Set up the laser on its side.
Note: If you’re using the laser with a tripod, an after-market vertical mounting
bracket is needed. For instruction on how to use the vertical mounting
bracket, consult the specific manufacturer’s instructions.
2. Press the manual button on the laser or radio remote control.
3. To adjust the laser beam for line direction, use the up and down buttons
on the laser or radio remote control until the laser beam matches the line
point.
4. To adjust the plumb position of the laser beam, use the up and down
buttons on the laser or the left and right buttons on the radio remote
control.
Establishing Control
Determining Height of Instrument (HI)
1. Set up the laser and turn it on.
2. Connect a receiver to a grade rod. Turn on the receiver.
3. Place the grade rod on a job-site benchmark (BM). Adjust the height of
the receiver until the receiver’s LCD shows an on-grade reading.
4. Add the grade-rod reading to the benchmark to determine the height of
instrument. Use the HI as a reference for all other elevation measurements.
Establishing Elevation Control Hubs
The elevation control hub can be used to re-establish the elevation of the
laser plane in case the laser setup gets disturbed.
1. Establish an elevation-control hub close to the laser and determine the HI.
Note: If you’re also going to establish a grade control hub, make sure the
elevation-control hub and grade -control hubs are on the same axis.
Establishing Grade Control Hubs
The slope control hub can be used to check the alignment of the laser on the
job site and to confirm the grade entered into the laser.
1. Check the grade on a minimum of three hubs on the job site. The hubs
should be in lines that are 90° from one another with one line containing
two hubs.
Note: Because the accuracy of this procedure is based on the known
elevation of the hubs, the exact elevation of the hubs is critical.
Note: If there isn’t enough space for the laser to be setup on the desired
centerline, the laser can be set up on a line parallel to the centerline (D1-D2).
Reversing the Grade
(One-Way and Two-Way Radio Remote Controls)
The sign of the ∠ axis can be changed using the one-way or two-way radio
remote control.
1. Set up the laser. Turn on the laser and flip its antenna up.
2. Turn on the radio remote control and make sure its antenna is pointing
skyward.
3. Select “Grade Reverse” from the menu using the mode button.
4. Press the enter button to confirm the selection.
Note: On a one-way radio remote control, “Reversing” appears in the radio
remote control’s LCD to indicate that the process is occurring and the sign
of the ∠ axis will be changed on the laser’s LCD.
Note: When grade reversing has been completed, “Grade Reversing
Complete” appears in the LCD. If “Grade Reversing Unconfirmed” appears
in the LCD, check the distance between the laser and radio remote control
and try reversing the grade again.
Note: On a two-way radio remote control, the sign of the ∠ grade value
reverses to indicate that grade reversing has been completed.
Automatic Alignment Modes Summary
The laser system has three automatic alignment modes:
• Axis Alignment
• Grade Matching
• PlaneLok
To use these modes, a radio remote control (one-way or two-way) and hand-
held receiver are required. The radio remote control and receiver are typically
mounted to a grade rod, which must be placed somewhere between 60 feet
(20 m) and 500 feet (150m) from the laser. Automatic axis alignment can take
from 1 to 5 minutes to complete.
Automatic Axis Alignment Mode
This automatic axis alignment function replaces the manual alignment scope
and vernier base traditionally used to align the desired grade axis to a hub.
When this mode is being used, the receiver and radio remote control are
mounted to a grade rod, the desired grade is dialed into the laser, and the
grade rod is placed on the hub that the grade axis is being aligned to. When
activated, automatic axis alignment mode adjusts the direction the desired
grade axis is pointing to by electronically simulating “rotating” the laser on its
mounting base. This mode is typically used for agriculture, road
construction, and steep-grade applications where precision alignment of the
grade axis is required.
Grade-Matching Mode
This automatic alignment function changes the grade of the desired axis to
automatically match an unknown grade.
When this mode is being used, the receiver and radio remote control are
mounted to a grade rod, the approximate grade (within 1.5% of the actual
grade) is dialed into the laser, and the grade rod is benchmarked to the laser-
beam elevation at a point within 3 feet (1 m) of the laser. Without changing
the receiver’s elevation on the rod, the grade rod is then placed anywhere a
grade reading is needed.
When activated, grade-matching mode automatically adjusts the grade up or
down to “search” for the receiver. When the center of the receiver is found,
the resultant grade is calculated and dialed into the laser, and displayed on the
two-way radio remote control (if being used).
When grade matching is complete, the receiver can be removed from the
alignment point and the calculated grade will remain in the laser. Both axes of
the laser can be grade matched in sequence. Grade-matching mode is used
for applications where the existing grade is not known, but will remain
relatively unchanged (such as installation of a sidewalk or driveway).
PlaneLok Mode
PlaneLok mode works like grade-matching mode, except the receiver is
permanently mounted to the desired elevation so that the laser can use the
receiver to continually monitor beam elevation. The laser ignores the internal
level vial for that axis, using the absolute elevation from the receiver for level
control.
PlaneLok Mode is used for applications where extreme precision of the laser-
beam elevation is required, such as runway applications.
Using Axis-Alignment and Grade-Reverse Modes
How Axis-Alignment Mode Works
Axis-alignment mode works by changing grade in the aligned-axis direction
and cross-axis directions then monitoring the elevation changes of the laser
beam at the receiver via the radio remote control. The desired axis-alignment
angle can then be calculated and the internal grade system “rotated”
electronically to align the simulated grade axis to the desired point.
Important Things to Know about Automatic Axis Alignment
Automatic Axis Alignment
• Replaces the alignment scope and vernier base traditionally used
• Can be done from any side of any axis of the laser, even if grade is dialed
into the opposite axis that’s being aligned
• Automatically adjusts the direction the grade axis is pointing to the
receiver/remote location
• Electronically simulates rotating the laser on its base to match the hub
For Proper Operation
• The desired grades must be entered into the laser
• The receiver must be at the correct alignment point
• The receiver must be between 60 feet (20 m) and 500 feet (150 m) from
the laser
For Best Accuracy
• Set up the laser to align to the elevation reference the farthest away (such
as the centerline of the road)
• If the hubs are equally distant, align to the hub with the smallest amount
of grade
Practical Application for Automatic Axis Alignment and Grade Reverse
Modes: Road Construction Setup
The main uses for the laser in road construction are for planar sections where
the road design calls for no vertical or super-elevated curves.
Automatic Axis Alignment Mode
1. Set up the laser over a point on the centerline of the road.
2. Using the sighting guide as a guide, rough align the laser with the
direction hub on the centerline.
Note: Because the laser can provide positive and negative slopes in the ∠
axis, make sure the laser’s handle is at a 90° angle to the centerline of the
road.
Note: If there isn’t enough space for the laser setup on the centerline, the
laser can be set up on a line parallel to the centerline of the road (D1=D2).
3. Enter the grade value for the axis that aligns with the centerline of the
road (∠).
4. Enter the grade value for the side of the road to be graded first into the
axis that is perpendicular to the centerline of the road (∠).
5. Connect a receiver and radio remote control to a grade rod.
6. Set the grade rod on the centerline direction hub.
7. Slide the receiver up/down the grade rod until the receiver’s LCD
shows an on-grade reading.
Note: The grade rod MUST be plumb.
8. Select “Axis Align” from the operational menu using the radio remote
control’s mode button.
9. Select the axis (∠ or ∠) that you are aligning using the up or down
buttons.
10. Press the enter button to confirm the selection. “Start” then “Wait”
appears on the LCD.
11. Hold the grade rod plumb and steady during automatic axis alignment.
Note: Alignment can take from 1 to 5 minutes to complete.
Note: When axis alignment has been completed, “Axis Alignment Complete”
appears in the LCD. If axis alignment fails, a failure message appears in the
LCD.
12. Check the laser’s alignment and grade values using previously
established elevation-control hubs and slope-control hubs as
references.
Note: If the alignment and grade values need small adjustments, they can be
changed using the radio remote control. See the “Correcting Slope/Height
Differences” section of this manual for more information.
13. Grade that side of the road
Grade Reverse Mode
Note: After you’ve finished grading one side of the road, you can reverse the
sign of the ∠ axis from the cab using the radio remote control.
1. Set the blade on a known elevation hub on the centerline of the road.
2. Select “Grade Reverse” from the operational menu using the radio
remote mode button.
3. Press the enter button to confirm the selection.
Note: On the one-way radio remote control, “Reversing” appears in the radio
remote control’s LCD to indicate that the process is occurring and the sign
of the axis will be changed.
Note: When grade reversing has been completed, “Grade Reversing
Complete” appears in the LCD. If “Grade Reversing Unconfirmed” appears
in the LCD, check the distance between the laser and radio remote control
and try reversing the grade again.
Note: On a two-way radio remote control, the sign of the grade display
reverses to indicate that grade reversing has been completed.
Practical Application for Axis Alignment Mode: Steep Grades Setup
(Embankments, Waste Dumps and Sea Walls)
1. Set up a tripod on an established offset from the baseline of the bank to
make sure that the laser beam will be at the required height above the
bank surface. Make sure that one of the tripod legs is aligned with the
down-grade side of the ∠ axis.
2. Connect the steep-grade adapter to the tripod.
3. Adjust the steep-grade adapter to the desired grade value.
4. Align the adapter with the direction hub on the top of the bank.
5. Connect the laser to the steep grade adapter making sure that the laser’s
handle is parallel with the baseline of the bank.
6. Make sure the desired slope and rotation speed are entered into the
laser.
7. Using the sighting guides as a guide, rough align the laser with the
direction hub.
8. Connect a receiver and radio remote control to a grade rod.
9. Set the grade rod on the direction hub.
10. Slide the receiver up/down the grade rod until the receiver’s LCD
shows an on-grade reading.
Note: The grade rod MUST be plumb.
11. Select “Axis Align” from the operational menu using the radio remote
control’s mode button.
12. Select the axis (∠ or ∠) that you are aligning using the up or down
buttons.
13. Press the enter button to confirm the selection. “Start” then “Wait”
appears on the LCD.
14. Hold the grade rod plumb and steady on the direction hub.
Note: Alignment can take 1 to 5 minutes to complete.
Note: When axis alignment has been completed, “Axis Alignment Complete”
appears in the LCD. If axis alignment fails, a failure message appears in the
LCD.
15. Check the laser’s alignment using previously established direction hub
and baseline hubs as references.
Note: If the alignment and grade values need small adjustments, they can be
changed using the radio remote control. See the “Correcting Slope/Height
Differences” section of this manual for more information.
Note: If the axis alignment should be done to the baseline hub #2
(perpendicular to the steep grade axis), attach the offset plate to the steep
grade adapter so that the rotor head of the laser is at the same axis as the
tripod mount. Follow the steps as described above with the only change that
the axis alignment using the grade rod has to be done at baseline hub #2
(steps 7, 9, and 14) instead of the direction hub.
Using Grade-Matching Mode
How Grade-Matching Mode Works
Grade-matching mode works by changing grade in the selected axis direction
then monitoring the elevation changes of the laser beam at the receiver via the
radio remote control. Once the laser “finds” the center of the receiver, the
resultant grade is calculated and stored in the laser and two-way remote
control.
Important Things to Know about Grade-Matching Mode
Grade-Matching Mode
• Automatically adjusts the grade of the selected axis to match an unknown
grade
• Searches for and finds “on-grade” of the mounted receiver within a 1.5%
grade range of the final grade (starting with the beam centered on the
receiver isn’t necessary)
• Stores and displays the resultant grade on the remote and laser
For Proper Operation
• The receiver can be removed after alignment, and the resultant grade
remains in the laser
• One or Both axes can be grade matched in sequence
• The initial grade MUST be within 1.5% of the final grade before starting
Practical Application for Grade-Matching Mode, One-Axis Setup: General
Construction Setup

message appears in the radio remote control LCD. (See the
“Troubleshooting” section of this manual for more information.)
Note: The resultant grade appears in the laser LCD display and on the two-
way remote control LCD display (if used).
Note: Alignment can take 1 to 5 minutes to complete.
Grade-Matching Mode: Two Axes Setup
This function can only be done on one axis at a time. The laser needs to be
aligned with one of the slope-control hubs in automatic axis alignment mode
before dual axes grade-matching mode can be activated.
1. Set up the laser over a reference point.
2. Using the sighting guide as a guide, rough align the laser with the slope-
control hub #1.
Note: The two slope-control hubs must be in lines that are at a 90° angle
from one another.
Note: The laser and the elevation-control hub must be on one axis.
3. Enter the approximate grade value for the ∠ axis and the ∠ axis.
Note: The automatic slope searching range is ±1.5%. The approximated
grade should be within 1.5% of the final matched grade.
4. Connect a hand-held receiver and radio remote control to a grade rod.
5. Set the grade rod on the elevation-control hub.

“Troubleshooting” section of this manual for more information.)
Note: The matched grade value for the aligned axis appears in the laser’s and
two-way radio remote control’s LCDs.
Note: Alignment can take 1 to 5 minutes to complete.
Using PlaneLok Mode
How PlaneLok Mode Works
PlaneLok mode works by changing grade in the selected axis direction then
monitoring the elevation changes of the laser beam at the receiver via the
radio remote control. Once the laser “finds” the center of the receiver, it
continues to monitor its position and makes small corrections to hold the
beam on-grade.
Important Things to Know about PlaneLok Mode
• Loss of receiver signal results in laser “out of level” mode (no laser beam
or rotation)
• The internal laser level vial for that axis is ignored (the receiver is used for
level control)
• The opposite axis levels to its internal level vial and grade
PlaneLok
• Works like grade match mode, except the receiver is permanently
mounted at the desired elevation to continually monitor beam elevation
• Is used for applications requiring extreme accuracy, such as in runway
applications
For proper operation
• The initial grade MUST be within 1.5% of the final grade before starting
Practical Application for PlaneLok Mode: Agricultural and Runway
Applications
Agriculture and runway applications can generally be handled using any of
the previously described processes. For extremely accurate agriculture or
runway applications whose work-time extends over several days or even
weeks, PlaneLok mode is recommended.
PlaneLok Mode Setup
1. Set up the laser over a reference point.
2. Using the sighting guide as a guide, rough align the laser with one of the
slope-control hubs.
Note: The two slope-control hubs must be in lines that are at a 90° angle
from one another.
3. Enter the approximate grade into the axis that needs to be aligned and
an exact grade value into the other axis.
Note: The automatic slope searching range is ±1.5%. The approximated
grade should be within 1.5% of the final matched grade.
4. Connect a receiver and radio remote control to a grade rod.
5. Set the grade rod on the elevation-control hub.
6. Slide the receiver up/down the grade rod until the receiver’s LCD
shows an on-grade reading.
Note: The grade rod MUST be plumb.
7. Go to the slope-control hub on the axis to be aligned and set the grade
rod on the hub. Make sure you DON’T change the height of the
receiver on the grade rod.
8. Select “PlaneLok” from the operational menu using the mode button.
9. Select the axis (∠ or ∠) that you are aligning using the up or down
buttons.
10. Press the enter button to confirm the selection. “Start” then “Wait”
appears in the LCD.
Note: Note: When the PlaneLok function has been completed, “PlaneLok
Complete” and a “Lock” icon (padlock symbol) appear in the radio remote
control LCD.
Note: Alignment can take 1 to 5 minutes to complete.
Note: If the PlaneLok function fails, the remote indicates the cause of failure.
See the ‘Troubleshooting” section of this manual for more information.
Note: The receiver should be permanently mounted at this location and at the
desired elevation. Use a bipod (commonly used with prism poles) to hold the
grade rod steady for the entire workday.
Note: The resultant grade on the locked axis is displayed in the remote LCD.
Note: The laser continues to servo to the receiver’s elevation signals. Any
loss of signal over an extended period of time (1 minute) causes the laser
beam to turn off and rotor to stop. The PlaneLok mode must be reactivated
when the laser experiences loss of signal over an extended period.
Using the Radio Remote Control to Correct Slope/Height Differences after
Setup
Sometimes, after performing any of the advanced alignment functions, the
alignment and grade values need small adjustments. These adjustments can
be made using a one-way or two-way radio remote control.
One-Way Remote
Checking Slope/Height Differences for the ∠ and ∠ Axes
1. Determine the height of the laser (HI) by setting the grade rod on
elevation-control hub #1.
2. Check the HI by setting the grade rod on elevation-control hub #2. Make
sure you DON’T change the height of the receiver on the grade rod.
Adjusting Slope/Height Differences for the ∠ and ∠ Axes
Small differences of the slope/height can be corrected using the up and down
buttons in 0.01% using “Grade Bump” mode.
1. Select “∠ Grade Bump” from the operational mode menu using the radio
remote control’s mode button.
2. Press the up or down button on the radio remote control until you get an
on-grade reading on the receiver. Each press of the up/down button
increases/decrease grade in .01% increments. To change the grade by
0.05%, for example, press and release the button five times.
3. Go to the elevation-control hub for the ∠ closed axis and set the grade
rod on the hub. Make sure you DON’T change the height of the receiver
on the grade rod.
4. Select “∠ Grade Bump” from the operational menu using the radio remote
control’s mode button.
5. Press the up or down button on the radio remote control until you get an
on-grade reading on the receiver. Each press of the up/down button
increases/decrease grade in .01% increments. To change the grade by
0.05%, for example, press and release the button five times.
Two-Way Remote
Checking Slope/Height Differences for the ∠ and ∠ Axes
1. Determine the height of the laser (HI) by setting the grade rod on
elevation-control hub #1.

sure you DON’T change the height of the receiver on the grade rod.
Adjusting Slope/Height Differences on the ∠ Axis
1. Select “∠ Grade” from the operational mode menu using the radio
remote control’s mode button.
2. Press the up or down button on the radio remote control until you get
an on-grade reading on the receiver.
Note: The new grade value appears on the radio remote control’s LCD.
3. Go to the elevation-control hub for the ∠ axis and set the grade rod on
the hub. Make sure you DON’T change the height of the receiver on
the grade rod.
Adjusting Slope/Height Differences on the ∠ Axis
1. Select “∠ Grade” from the operational mode menu using the radio
remote control’s mode button.
2. Press the up or down button on the radio remote control until you get
an on-grade reading on the receiver.
Note: The new grade value appears on the two-way radio remote control’s
LCD.

Calibration
As with any precision instrument, the calibration needs checking on a regular
basis (such as the beginning of each job, or if the laser has been handled
roughly). If the laser is to be used below freezing, be sure to check
calibration under those conditions.
The laser has a calibration error when the laser plane coming out one side of
the laser is above true level, and the laser plane coming out the opposite side
is below true level. Adjusting the position of the laser plane requires making
minor adjustments the leveling mechanism using the up and down buttons on
the control panel.
When the laser is properly calibrated, it emits a 360° horizontal level plane so
that if the laser is turned 180° or 90° from its original position, the reading is
within ±5/16 in. per 300 ft (±8 mm/90 m) of the original position.
To check the horizontal calibration, you’ll need a tripod with a 5/8-11
threaded mount and a hand-held receiver. If you need to adjust the
calibration, having another person to help saves time.
Checking Calibration
1. Set up the laser 300 ft (90 m) from a wall.
2. Set the grade to 0.000% in both axes.
3. Raise/lower the receiver until you get an on-grade reading for the +∠
axis. Using the on-grade marking notch as a reference, make a mark on
the wall.
Note: For increased precision, use the fine-sensitivity setting (+1/16 in./+1.6
mm) on the receiver.
4. Rotate the laser 180° (–∠ axis toward the wall) and allow the laser to re-
level.
5. Raise/lower the receiver until you get an on-grade reading for the –∠
axis. Using the on-grade marking notch as a reference, make a mark on
the wall.
6. Measure the difference between the two marks. If they differ more than
5/16 in. (8 mm), the laser needs calibrating.
Adjusting the Calibration at the Laser
1. Position the receiver at the midpoint of the two marks on the wall.
2. Add/subtract grade in the appropriate axis using the up/down buttons.
The grade appears in the LCD.
Note: The up/down buttons needed to calibrate the ∠ axis on single slope
lasers are “hidden” behind the control panel.
3. When the beam is centered in the receiver, use the following “hidden”
button sequence to store the new calibration value and to zero out the
grade display:
a) Press and hold the manual button
b) Quickly press and release the power button (do NOT press the
power button long enough to turn off the laser
c) Press and release the up button for the ∠ axis
d) Release the manual button
e) The grade display will zero out to indicate calibration is
complete.
4. Rotate the laser 180° back to the original face. Make sure this axis is less
than 5/16 in. (8 mm) from the midpoint line.
Note: If additional adjustment is required, repeat steps 1-3 above.
5. After adjusting the ∠ axis, rotate the laser 90°. Repeat the above starting
with the –∠axis facing the wall.
Adjusting the Calibration Using the Radio Remote Control
1. Position the receiver at the midpoint of the two marks on the wall.
2. Add/subtract grade in the appropriate axis using the grade
increase/decrease modes (one-way radio remote control: Grade Bump;
two-way radio remote control: Grade Change).
3. When the beam is centered on the receiver’s LCD, use the following
radio remote control button sequence to store the new calibration point
and to zero out the grade display:
f) Turn off the radio remote control
g) Press and hold the manual button
h) Turn on the radio remote control. “Calibration” appears in the
LCD.
i) Press the enter button to confirm the selection.
j) The grade display on the laser and two-way radio remote
control will zero out to indicate calibration is complete.
4. Rotate the laser 180° back to the original face. Make sure this axis is less
than 5/16 in. (8 mm) from the midpoint line.
Note: If additional adjustment is required, repeat steps 1-3 above.
5. After adjusting the ∠ axis, rotate the laser 90°. Repeat the above starting
with the –∠axis facing the wall.

How to Use the Laser System
Laser
Powering the Laser
Batteries
Depending on the laser system configuration that you purchase, the laser is
shipped with either rechargeable nickel-cadmium (Ni-Cd) or nickel/metal-
hydride (Ni-MH) batteries. Even if you buy a laser that uses Ni-Cd batteries,
you can upgrade to Ni-MH batteries. Alkaline batteries can also be used as a
backup; however, rechargeable batteries should be reinstalled in the laser as
soon as possible.
Installing/Removing the Batteries
CAUTION: The batteries should be removed when storing the laser more
than 30 days.
1. Remove the four screws from the battery housing. Remove the battery-
housing compartment.
2. Install/remove the batteries.
Note: When installing the batteries, be sure to note the positive (+) and
negative (-) diagram inside of the housing.
Note: The laser has reverse polarity protection. If the batteries are put in
wrong, no damage occurs to the laser but it does not work. Allow it one
minute to recover after the batteries have been installed correctly.
3. Put the battery-housing compartment in place and reinstall the four
screws.
To let you know when the batteries are getting low, the status LED flashes.
When the status LED flashes yellow, the laser has less than one hour of
running time. When the status LED remains on solid yellow, the batteries
have less than five minutes running time.
Connecting the Laser to a Tripod
All lasers have a 5/8-11 tripod mount on the bottom of the laser. Depending
on the laser system you purchase, additional mounting adapters may be
shipped with your laser. The long-range (agricultural) laser system includes
a quick-disconnect adapter and a 3 1/2-8 adapter. The steep-grade laser
system includes a steep-grade adapter and offset plate.
The laser can also be connected to a standard tripod, column clamp, or other
mounting device. If you’re using the laser without a tripod, however, make
sure you set the laser on a stable surface.
1. Insert the tripod’s 5/8-11 screw into the laser’s threaded 5/8-11 tripod
mount.
2. Turn the screw counterclockwise to hold the laser securely in place.
3. To detach the laser from the tripod, turn the screw clockwise.
Turning On/Off the Laser
1. Press the power button to turn on the laser.
Note: The laser always powers up in the automatic self-leveling mode. If the
laser is out of its self-leveling range and remains out of it for more than 30
minutes, the laser shuts down completely.
Note: When the laser is initially turned on, the LCD shows the approximate
charge of the batteries, the laser beam’s rotation speed, and manual axis-
alignment position if it’s other than zero. After the LCD shows this
information, the last-entered grade immediately appears in the LCD. The
status LED flashes green to indicate that the laser is self-leveling. After the
laser has self-leveled at the indicated grade, the laser beam rotates and the
status LED stops flashing.
Note: After the laser has been level for more than 30 minutes, the HI alert
activates. If the laser is disturbed (tripod bumped, etc.) so that when it re-
levels the laser beam elevation changes by more than 1/8 in. (2.5 mm), the
HI alert shuts down the laser and rotor, and the status LED flashes red two
times per second (twice the manual-mode rate).
2. To turn off the laser, press and hold the power button for three seconds.
Selecting the Rotation Speed
The laser has three laser beam rotation speeds—300, 600, and 900 rpm. The
rotation speed can be changed at any time to meet your job-site conditions.
Use 600 rpm for held-held receivers and most machine-control systems.
The rotation speed can also be changed using either of the radio remote
controls. The rotation speed appears in the two-way radio remote control’s
LCD. If you’re using a one-way radio remote control, you must look at the
laser’s LCD for this information. For more information about using the radio
remote control, see the operator’s manual.
1. Repeatedly press and release the rotation-control button until the desired
rotation speed appears in the LCD.
Note: The selected rotation speed briefly appears in the LCD. After a few
seconds, the selected percentage of grade appears in the LCD.
Changing the Grade Value
The grade value for both axes can be changed using two methods—standard
and quick-change. The standard method is used for entering small changes
in the grade value. The quick-change method is used for setting grade to
zero and entering large changes in the grade value.
The grade value can also be changed using either of the radio remote
controls. The grade value appears in the two-way radio remote control’s
LCD. If you’re using a one-way radio remote control, you must look at the
laser’s LCD for this information. For more information about using the radio
remote control, see the operator’s manual.
Standard Method
Note: The grade value can be quickly set to 0.000% by simultaneously
pressing and releasing the up and down buttons for the axis you want to
change.
1. Press and hold the up or down button for the axis you want to change
until the correct grade value appears in the laser’s LCD.
Note: The speed of the grade value change increases with the amount of time
the button is held down.
Note: Grade values from -0.500 to 9.999% are displayed in thousandths of a
percents. Grade values greater than 10% are displayed in hundredths of a
percent.
Note: All changes to the axis-alignment rotation made prior to changing the
grade value using the standard method are retained.
Quick-Change Method
1. Simultaneously press and hold the up and down buttons for the axis you
want to change to set the grade value to 0.000%.
Note: The grade value for the ∠ axis increases in 1.00% increments. The
grade value for the ∠ axis increases in 5.00% increments.
2. Continue pressing and holding the up and down buttons until the correct
grade value appears in the laser’s LCD.
Note: When the grade value for either axis reaches its highest amount, the
grade value switches to the lowest value for that axis. In the ∠ axis, for
example, the value switches from +10.00% to –10.00%. In the ∠ axis, the
value switches from 25.00% to -0.500%. For steep-grade lasers, the value
switches from 110.00% to -0.500%.
Note: All changes to the axis-alignment rotation made prior to changing the
grade value using the quick-change method are cancelled.
Activating/Deactivating Manual Mode
Manual mode bypasses the laser’s automatic self-leveling mode so you can
use the laser in vertical mode. Manual mode also allows you to tilt the laser
beyond its built-in sloping capability so you can perform steep-sloping
horizontal applications.
Manual mode can also be activated/deactivated using either of the radio
remote controls. The words “Manual Mode” appear in the two-way radio
remote control’s LCD when manual mode is activated. If you’re using a one-
way radio remote control, you must look at the laser’s LCD for this
information. For more information about using the radio remote control, see
the operator’s manual.
1. Make sure the laser is on and in the orientation appropriate for your
application needs (horizontal or vertical).
2. Press the manual mode button.
Note: When manual mode is activated, the status LED flashes red once per
second and scrolling horizontal segments appear in the LCD.
3. To adjust the laser in the ∠ axis so that the laser beam matches the
desired slope or grade, use the ∠ axis up and down buttons on the laser or
radio remote control.
4. To adjust the laser in the ∠ axis so that the laser beam matches the
desired slope or grade, use the ∠ axis up and down buttons on the laser or
the left and right buttons on the radio remote control.
5. To resume automatic self-leveling mode, press the manual button on the
laser or radio remote control again.
Aligning the Axis Manually
The manual axis alignment buttons rotate the grade axis electronically
(simulates turning the laser on its tripod, with fine adjustment capability up
to a maximum of ±40 degrees).
1. Set up the laser over a reference point. Make sure the laser is positioned
so that the ∠ and ∠ axes are pointing in the right direction.
2. Using the sighting guides as guide, rotate the laser on its tripod to align
the laser to the direction hub.
3. Turn on the laser and allow it to self-level.
4. Connect a receiver to a grade rod and turn on the receiver. Make sure you
position the receiver so that it is at the correct elevation for the distance
(and grade) from the laser to the direction hub.
5. Set the grade rod on the direction hub.
Note: If only one person is manually aligning the laser, use a bipod
(commonly used with prism poles) to keep the grade rod plumb when
placing is on the direction hub.
6. Press the appropriate manual axis alignment button to align the laser
plane to the receiver. The clockwise axis alignment button rotates the
laser clockwise; the counterclockwise axis alignment button rotates the
laser counterclockwise.
7. Press and hold the axis alignment button until you get an on-grade
reading on the receiver.
Radio Remote Control (One-Way and Two-Way)
The radio remote control is a hand-held device that allows you to send
operational commands to the laser from a remote location. These operational
commands include changing grade values, rotation speed, and operating
modes. The radio remote control HAS to be used for the following advanced
alignment features:
• Automatic Axis Alignment
• Grade Reverse
• Grade Matching
• PlaneLok
See your operator’s manual for detailed setup and operation of these
advanced features.
A solid “T” symbol appears in the right corner of the LCD to indicate that
the link between the radio remote control and laser is complete. A flashing
bar above the “T” indicates that communication with the laser is established.
When the radio remote control is connected to a receiver, an “R” appears in
the right corner of the radio remote control’s first display line indicating that
a connection has been made and the power is on.
When using the radio remote control, make sure its antenna is pointing
skyward.
Turning On/Off the Radio Remote Control
1. Press the power button to turn on the radio remote control.
Note: When the two-way radio remote control is initially turned on, the axes
symbols and last-entered grade for each axis briefly appear in the LCD.
2. To turn off the radio remote control, press and hold the power button
for 3 seconds.
Selecting the Operational Mode
The mode button allows you to choose the laser’s operational mode, which
includes changing grade, automatic axis alignment, grade matching,
PlaneLok, grade bump, grade reverse, manual, and beam rotation speed.
1. Repeatedly press and release the mode button to cycle through the
operational menu. The menu selections appear in the radio remote
control’s LCD.
