Setting Up the Laser
The laser facilitates various set-ups, making it useful
for several applications.
MANUAL HEAD ROTATION
The laser is designed with a protective alloy cage
around the rotary head to prevent accidental
damage from work site activities. You can still
access the rotary head and manually direct the
beam to establish or transfer a mark.
WALL SET-UP (FIG. 3)
The wall mount is used for mounting the laser to a
wall track to aid in drop ceiling installation and other
specialty levelling projects.
1. Place the laser on the mounting base (aa),
aligning the hole (kk) on the bottom of the laser
with the hole (bb) in the mounting base. Turn
the mounting knob (cc) to secure the laser.
2. With the wall mount measuring scale (dd) facing
you, loosen the wall mount clamp locking knob
(ee) to open the clamp jaws.
3. Position the clamp jaws around the wall track
or ceiling angle and tighten the wall mount
clamp locking knob (ee) to close the clamp
jaws onto the track. Be sure that the wall mount
clamp locking knob is securely tightened before

4. Using the base leveling knob (gg), approximate
a level position from the wall.
CAUTION: Before attaching the laser
level to wall track or ceiling angle, be
sure that the track or angle is properly
secured.
CAUTION: Always use a ceiling wire
hanger or equivalent material, in addition
to the wall mount clamp locking knob,
to help secure the laser level while
mounting it to a wall. Thread the wire
through the handle of the laser level.
DO NOT thread the wire through the
protective metal cage. Additionally,
screws may be used to fasten the wall
mount directly to the wall as a back-up.
Screw holes (ff) are located at the top of
the wall mount.
