THE DETECTOR GIVES OFF A TONE BUT THE LCD

detector to a D

Construction Grade Rod

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

EWALT Grade Rod 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

FIG. 12

scale starting at the bottom. Use this for measuring

from the ground up when grading or leveling jobs.

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 12.

Using the Laser with a Wall Mount

(Fig. 13, 14)

Some laser kits include a Wall Mount. It can be used for attaching

the tool to track or ceiling angle and to aid in acoustical ceiling

installation. Follow the directions below for using the wall mount.

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 (BB) aligning the hole

(CC) on the bottom of the laser with the hole (DD) in the

mounting base. Turn the mounting knob (EE) to secure the

laser.

2. With the wall mount measuring scale (FF) facing you, loosen the

wall mount clamp locking knob (GG) 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 (GG) 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
