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 (QQ) are
located at the top of the wall
mount.
4. Using the base leveling
knob (RR) approximate
a level position from the

offset height for working. To change the height, loosen the
locking knob (SS) located on the left of the wall mount. Support
the mounting base when adjusting the height.
6. Turn the adjustment knob (TT), located to the right of the wall
mount, to move the laser level up and down to set your height.
Use the wall mount measuring scale (OO) to pinpoint your
mark.
NOTE: It may be helpful to turn the power on and turn the
rotary head so that it puts a dot on one of the laser scales. The
D WALT target card is marked at 1-1/2" (38 mm), therefore, it
E
may be easiest to set the offset of the laser to 1-1/2" (38 mm)
below the track.
7. Once you have positioned the laser at the desired height,
tighten the locking knob (SS) to maintain this position.

LASER MAINTENANCE

• Under some conditions, the glass
lens inside the rotary head may
collect some dirt or debris. This will
affect beam quality and operating
range. The lens should be cleaned
with a cotton swab moistened with
water as shown in Figure 16.
• The flexible rubber shield can be
cleaned with a wet lint-free cloth
such as a cotton cloth. USE WATER ONLY — DO NOT use
cleansers or solvents. Allow the unit to air dry before storing.
• To maintain the accuracy of your work, check the calibration of
the laser often. Refer to Field Calibration Check.
• Calibration checks and other maintenance repairs can be
performed by D WALT service centers. Two free calibration
E
checks are included under the D
Con tract.
