APPLICATIONS
Setting LM-PL20 (All models)
Set Up of the Laser at the Correct Elevation (HI)
All height references are given in relationship to the Invert Elevation (inside lowest point of pipe).
1. Attach the LM-PL20 to the trivet plate or position in the manhole on the correct feet.
Care should be taken that the LMPL20 is positioned on the correct centerline.
2. Use the three leveling screws to adjust the trivet plate to approximate level condition (not required
when mounting on self centering feet with pre-poured inverts - as the invert should be at the
correct elevation).
16 • LMPL20
LMPL20 • 17
3. Where pre-poured inverts are used be sure to attach the correct feet size and set the laser in the center
of the invert (Fig. 26).
4. Use an optical level or rotating laser level to obtain the elevation from the elevation rod or (See Fig. 26)
5. Add the cut amount obtained from the stake to the elevation obtained by the optical level or laser.
6. This dimension is the distance from the optical level or laser to the invert of the pipeline - so subtract
the distance from the invert to the center of the laser spot.
7. Place the grade rod in the manhole at the correct elevation and position the laser at the correct height
in relation to the grade rod.
8. Note that the grade rod can be positioned on the top of the LMPL20 and a correction of - 2.78
inch (70.5mm) is required.
How To Set The Grade
To set grade follow procedures as described in section “Grade” page 8.
How To Establish and Set Line or Direction
Procedure 1 (Fig. 27)
1. Set the LTU or Transit over the centerline of the pipe using a plumb bob and offset measurement.
2. Position the sighting scope of the transit so that the vertical crosshair is aligned to the next
manhole position of line stake.
3. Plunge the sighting scope into the area where the laser is set up and position the laser pivot or
alignment crosshair point.
4. Bring up the scope so that the vertical crosshair is in the position of the open trench in front of the laser
where the laser spot will project.
5. Using the remote control RC20 drive the line adjustment left or right until the laser spot Is in line with the
vertical crosshair In the scope.
6. The laser housing and the laser spot in front of the laser are now aligned with the axis of the pipeline
stakes and pipe laying can begin.
Procedure 2 (Fig. 28)
1. Mount the Manhole Mount Transit Tower (optional) to the manhole and position the optical
instrument or transit directly over the centerline of the pipeline.
2. Drop a plumb bob down from the optical instrument and position the pipe laser at the pivot point
directly under the plumb bob.
3. Align the optical instrument by the vertical crosshair to the next manhole position stake.
4. After locking the horizontal rotation, plunge the scope into the trench at a convenient spot to view the
laser spot.
5. Using the remote control RC20 drive the left or right direction control until the laser spot is aligned with
the crosshair in the optical instrument.
6. The LMPL20 is aligned with the pipeline axis and pipe laying can begin.
Procedure 3 ( LMPL20 )
1. Position the LMPL20 exactly in the center of a poured invent or centerline marked on the bottom
of the manhole so that the pivot point is on the centerline.
2. Attach the loose end of a plumb bob cord to the notch on the LMPL20 at the pivot point.
3. Extend this cord to the top of the manhole and so that the cord is supported over the thumb of the
operator. The free end with the plumb bob then hangs from the thumb of the operator.
4. Using the cord from the thumb to the plumb bob as a guide move the thumb left or right until both sides
of the cord are vertical and aligned with the next manhole stake.
5. Using the remote control RC20 drive the left or right direction control until the laser spot is aligned with
the both of the vertical cords.
6. The LMPL20 is aligned with the pipeline axis and pipe laying can begin.

Setting Excavation, Base Material and Pipe Elevation (Fig. 29)
1. To accurately set the base elevation for pipe laser use, you must be able to calculate the base elevation
from the center of the pipe laser beam.
Using the sample information below, you will be able to calculate your base elevation as described above.
• Consider a pipe diameter of 12" (300mm)
• Use a pipe thickness of 1" (25mm)
• Consider a base material thickness of 6" (150mm)
Example:
To calculate the base elevation, take the pipe radius 12" divided by 2 = 6" (300mm/2 = 150mm)
Next using the pipe thickness and the base material (1" or 25mm) and (6" or 150mm) respectively
Calculate the distance from beam to base elevation as follows
Pipe Radius + Pipe Thickness + Base Material Thickness = Base Elevation
6" + 1" + 6" = 13" or 150mm + 25mm + 150mm = 325mm
2. You may now utilize any leveling rod, direct elevation rod or grade stick and the pipe laser beam to
control the excavation depth by marking a reference point on your rod at the height detailed above, (13"
or 325mm). Utilize the beam control of the LM-PL20 to match up to the marks on the grade stick or
level rod.
3. In some cases, it may be necessary to set a sub base elevation to begin work. To set a sub-base
elevation, calculate the distance from the center of the beam as follows:
Example:
To calculate the sub-base, utilize the information below.
Pipe Diameter: 12" (300mm) as detailed in the example above
Pipe thickness: 1" (25mm) as detailed in the example above
Distance from beam to sub base elevation
To calculate the first step, take the pipe radius 12" divided by 2 = 6" (300mm/2 = 150mm)
Next using the pipe thickness and the base material (1" or 25mm) and (6" or 150mm) respectively
Calculate the sub-base elevation as follows
Pipe Radius + Pipe Thickness = Sub-Base Elevation
6" + 1" = 7" or 150mm + 25mm = 175mm
4. You may now utilize any leveling rod, direct elevation rod or grade stick and the pipe laser beam to
control the elevation of the sub-base material by marking a reference point on your rod at the
height detailed above, (7" or 175mm).
5. Finally to set the LMPL20 to the correct elevation for use, place the pipe target in the pipe using the
target associated with the size of pipe you are setting. Then adjust the pipe until the laser beam is
precisely in the center of the alignment center of the target. Ensure that the center of the beam is
exactly in the center of the bulls-eye on the target. Once there, set the pipe and fill accordingly to
maintain grade.
In-the-Pipe Set up. (Fig. 30)
Assuming that some pipe has already been installed or laid, the LM-PL20 Pipe Laser can easily be positioned
inside the pipe for additional use.
LMPL20 • 19
1. Install the correct leg set for the pipe wishing to be installed
2. Place the pipe laser into the last section of pipe and ensure that the LMPL20 is positioned at the right
rotation and direction. Review the steps to ensure level and direction.
3. Place the pipe target in the last section of pipe to install ensuring the target is also positioned so that it
is level using the level vial on the target mount.
4. Using the included Remote Control or the LMPL20 keypad, guide the pipe laser beam so that it is in the
center of the target. You may use the remote control from the position of the end target to guide
the beam.
This will ensure accuracy in set up and allow one person to set the LMPL20 up for use. By using the LMPL20
keypad, it may be necessary to have a person at both the LMPL20 and target in order to guide the laser beam to
the center of the target.
Refer to section of Preparing LMPL20 for use for additional set up information.
Grade Checking (Fig. 31)
In order to ensure that you are laying pipe at the correct grade, it may be necessary to check pipe grade to
ensure that the laser has been set for the appropriate grade and line. This should be completed after
approximately 25 to 50ft (8 to 15m) pipe has been installed.
1. Utilizing an Automatic Level or Level Transit, measure a reference elevation at starting point
A. (See Figure 31)
2. Measure the elevation at ending point B with the level or level transit
3. Determine the elevation of pipe end point B in the same manner.
4. Using the standard Rise over Run X 100 calculation you can easily determine the grade.
Take (A-B) = Rise
Take Horizontal Distance = Run
((A-B)/Hz Distance) X 100 and you will have the grade of the installed sections.
If your measured grade does not match the intended grade, please review your initial laser or target set up to
ensure accurate LMPL20 set up.
