Mounting To Tripod (3)

Mounting To Wall

1. If mounting the Laser Level with the Tripod (3),
position the Tripod on a flat and level ground surface.
Extend Tripod Legs to the desired height, using the
Bull’s Eye Vial (15) located on the Tripod Head (4).
See Figure 2, below.

1. The Laser Level may also be installed on a wall
surface without the Tripod. To do so, use the Wall
Bracket (7A) to secure the Laser Level to the wall.

Figure 2

2. First, set the Level Housing against the part of
the wall where you wish to install the Laser Level.
WARNING! Verify that installation surface has no
hidden utility lines before drilling or driving screws.
3. Use a pencil to mark drill holes through the
Wall Bracket (7A). See Figure 4, below.

2. Once the Tripod is level, lock the legs in
place using the clamps on each leg.
3. Then thread Wall Bracket (7A) onto
Tripod Head. See Figure 3, below.

Figure 4
4. Secure the Laser Level to the wall surface
using screws and plastic anchors (not included).
NOTE: The mounting screws must be long enough
to allow for the Wall Bracket frame to fit over them.

Operating Instructions
Read the ENTIRE IMPORTANT
SAFETY INFORMATION section at the
beginning of this manual including
all text under subheadings therein
before set up or use of this product.

Initial Leveling

Installing Horizontal Or
Vertical Objects
1. For example, to install a chair rail on an interior
wall, first mark the desired height of the rail.
2. Align the Laser Level with that point, and check to
make sure the Vial Levels (9A) are level with the floor.
3. Shine laser beam on the adjoining wall, and
have an assistant mark that location.

1. When the Laser Level is properly positioned,
activate the Laser by turning the Power /
Rotation Control Switch (11A), clockwise.
Then recheck the Level Vials (9A) to make sure
the Laser Level has not been bumped or moved.
2. The rotation speed of the Laser Head Cover (6A)
can be set by adjusting the Rotation Control Switch.
Turn clockwise to make the beam rotate faster.
Turn counterclockwise to slow the beam down.
3. Mark the desired measurement(s).
Then turn off the Laser Level by turning the Rotation
Control Switch counterclockwise all the way.

Equalizing Height Of
Distant Objects
1. For example, if you wish to install cement
footings for a storage shed, first determine the
desired height of any one of the footings.
2. Align the laser beam with the top surface of the
reference footing, and check to make sure the
Vial Levels (9A) are level with the ground.

4. Then, install the chair rail in a direct
line between the two points.
5. This technique can be used to install
vertical or 45 degree angle objects.

Checking a Slope
1. For example, to determine the slope of
a floor, place the Laser Level at one end
of the floor, using the Tripod (3).
2. Check to make sure the Vial Levels (9A) are level.
3. Measure the vertical drop from the
Laser Lens to the floor surface.
4. Shine the laser beam on a ruler held vertical at
the other end of the floor. The difference in these
measurements is the amount of slope in the floor.
5. This technique can be used to design slope,
such as when constructing an outdoor
surface which will require a runoff slope.

3. Direct laser beam toward each of remaining
footing locations. On reference stakes at those
locations, mark the spot the Laser illuminates.
This indicates desired top surface of that footing.
4. This technique can be used for many similar
applications, i.e., to align pictures on a wall.

Maintenance and Servicing
Procedures not specifically explained
in this manual must be performed
only by a qualified technician.

TO PREVENT SERIOUS INJURY
FROM ACCIDENTAL OPERATION:
Turn OFF the Laser Level before performing any
inspection, maintenance, or cleaning procedures.
TO PREVENT SERIOUS INJURY FROM TOOL
FAILURE: Do not use damaged equipment.
If abnormal noise or vibration occurs, have
the problem corrected before further use.

Cleaning, Maintenance,
and Lubrication
1. BEFORE EACH USE, inspect the general
condition of the Laser Level. Check for loose
hardware, misalignment or binding of moving
parts, cracked or broken parts, and any other
condition that may affect its safe operation.
2. AFTER USE, wipe external surfaces of
the tool with clean cloth. Do not immerse
the Laser Level in any liquids.
3. Store the Laser Level indoors and
out of children’s reach.
