Maintenance - DeWalt DW079LR Instruction Manual


CAUTION: Before attaching the laser level to wall
track or ceiling angle, be sure that the track or angle is
properly secured.
1. Place the laser on the mounting base
11 screw hole on the tripod adapter (
the bottom of the laser with the hole
base. Turn the mounting knob
2. With the wall mount measuring scale
loosen the wall mount clamp locking knob
clamp jaws.
3. Position the clamp jaws around the wall track or ceiling
angle and tighten the wall mount clamp locking knob
to close the clamp jaws onto the track. Be sure that the
wall mount clamp locking knob is securely tightened
before proceeding.

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
are located at the top of the wall mount.
4. Using the base leveling knob
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 45 located on the left of the wall mount.
Support the mounting base when adjusting the height.
6. Turn the adjustment knob
wall mount, to move the laser level up and down to set
your height. Use the wall mount measuring scale
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),
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
Mounting on a Grade Rod (Fig. K)
To secure your detector to a grade rod, first attach the detector
to the clamp using the 1/4"‑20 threaded knob
of the clamp. Slide the tracks
rail 33 on the grade rod.
1. Position the detector at the height needed and turn the
clamp knob clockwise to tighten the jaws of the clamp
around the grade securing the clamp on the rod.
2. To make adjustments in height, slightly loosen the clamp,
reposition and retighten.

Construction Grade Rod (Fig. L)

DANGER: NEVER attempt to use a grade rod in a storm
or near overhanging electric wires. Death or serious
personal injury will occur.
Some laser kits include a grade rod. The D
is marked with measurement scales on both sides and is
constructed in telescoping sections. A spring‑loaded button
actuates a lock to hold the grade rod at various lengths.
The front of the grade rod has the measurement scale starting
at the bottom. Use this for measuring from the ground up
when grading or leveling jobs.
42
The back of the grade rod is designed to measure the height
of ceilings, joists, etc. Fully extend the top section of the grade
rod until the button locks into the previous section. Extend that
section either until it locks into the adjacent section or until the
grade rod touches the ceiling or joist. The height is read where
the last extended section exits the previous lower section, as
shown in Figure L.
Target Card (Fig. G)
Some laser kits include a Laser Target Card to aid in locating
43
and marking the laser beam. The target card enhances the
visibility of the laser beam as the beam crosses over the card.
The card is marked with standard and metric scales. The laser
beam passes through the red plastic and reflects off of the
reflective tape on the reverse side. The magnet at the top of
the card is designed to hold the target card to ceiling track or
steel studs to determine plumb and level positions. For best
performance when using the Target Card, the D
should be facing you.
Laser Enhancement Glasses (Fig. F)
to
Some laser kits include a pair of Laser En hancement Glasses.
These glasses improve the visibility of the laser beam under
bright light conditions or over long distances when the laser is
used for interior applications. These glasses are not required to
operate the laser.

CAUTION: These glasses are not ANSI approved safety
glasses and should not be worn while operating other
tools. These glasses do not keep the laser beam from
entering your eyes.

DANGER: To reduce the risk of serious personal injury,
never stare directly into the laser beam, with or without
these glasses.

MAINTENANCE

• Under some conditions, the glass lens 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.
• The flexible rubber roll bar and yellow plastic housing 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.
