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 roll cage. Additionally, screws may be used
to fasten the wall mount directly to the wall as a back up. Screw
holes (HH) are located at the top of the wall mount.
4. Using the base leveling knob
(II) approximate a level
position from the wall.
5. The tool can be adjusted
up and down to the desired
offset height for working. To
change the height, loosen
the locking knob (JJ) located
on the left of the wall mount.
Support the mounting base
when adjusting the height.
6. Turn the adjustment knob (KK), 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 (R) to pinpoint your mark.
NOTE: The D WALT target card is marked at 1-1/2" (38 mm),
E
therefore, it 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 (JJ) 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 15.
• 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
performed by D WALT service
E
centers. Two free calibration
checks are included under the
D WALT One Year Free Service
E
Con tract.
• When the laser is not in use, store it in the kit box provided.
• Do not store your laser in the kit box if the laser is wet. Dry
exterior parts with a soft, dry cloth and allow the laser to air dry.
• Do not store your laser at temperatures below 0˚F (-18˚C) or
above 105˚F (41˚C).
WARNING: Never use solvents or other harsh chemicals for
cleaning the non-metallic parts of the tool. These chemicals may
weaken the materials used in these parts. Use a cloth dampened
only with water and mild soap. Never let any liquid get inside the
unit; never immerse any part of the unit into a liquid. Never use
compressed air to clean the laser.
Field Calibration Check (Fig. 16, 17)
Field calibration checks should be done frequently. This section
provides instructions for performing simple field calibration checks
of your D WALT Rotary Laser. Field calibration checks do not
E
calibrate the laser. That is, these checks do not correct errors in the
leveling capability of the laser. Instead, the checks indicate whether
