Installing AA Batteries
E
Load new AA batteries in the DW08302 or DW08302CG laser.
1.
Turn the laser 180° in the attached pivot bracket (Figure
)..

2.
On the bottom of the laser, lift up the latch to open the battery
compartment cover (Figure
3.
Insert two new, high-quality, name brand AA batteries, making
sure to position the - and + ends of each battery as noted
inside the battery compartment (Figure
4.
Push the battery compartment cover closed until it snaps in
place (Figure

When the laser is not in use, keep the Power/Transport Lock
switch in the left (OFF) position (Figure
power.
Turning the Laser On
1.
Place the laser on a smooth, flat, level surface, with the
laser facing straight ahead toward the opposing wall (0º
position).
2.
Move the Power/Transport Lock switch to the right (Figure
) to unlock the pendulum and display the three laser
A 2
dots.
3.
Check the laser dots.
• If the laser is tilted so much that it cannot self-level
(> 4°), the laser dots will flash.
• If the laser dots flash, the laser is not level (or plumb) and
should NOT BE USED for determining or marking level or
plumb. Try repositioning the laser on a level surface.
4.
If ANY of the following statements are TRUE, continue with
the instructions for Checking Laser Accuracy BEFORE
USING THE LASER for a project.
• This is the first time you are using the laser (in case the
laser was exposed to extreme temperatures).
• The laser has not been checked for accuracy in
a while.
• The laser may have been dropped.

Checking Laser Accuracy
The laser tools are sealed and calibrated at the factory.
It is recommended that you perform an accuracy check
C
prior to using the laser for the first time (in case the laser
was exposed to extreme temperatures) and then regularly to
ensure the accuracy of your work. When performing any of the
accuracy checks listed in this manual, follow these guidelines:
• Use the largest area/distance possible, closest to the
operating distance. The greater the area/distance, the easier
to measure the accuracy of the laser.
• Place the laser on a smooth, flat, stable surface that is level
in both directions.
• Mark the center of the laser beam (dot).
Plumb Dot Accuracy
Checking the plumb calibration of the laser can be most
accurately done when there is a substantial amount of vertical
height available, ideally 25' (7.5 m), with one person on the floor
positioning the laser and another person near a ceiling to mark
the dot created by the beam on the ceiling.
1.
Mark point P1 on the floor (Figure
2.
Turn the laser ON to display dots above, ahead, and below
the laser.
3.
Place the laser so that the down dot is centered over point
P1 and mark the center of the up dot on the ceiling as point
P2 (Figure
).

4.
Turn the laser 180°, making sure that the down dot is still
centered over point P1 on the floor (Figure
5.
Mark the center of the up dot on the ceiling as point P3
(Figure
).

6.
Measure the distance between points P2 and P3.
7.
If your measurement is greater than the Allowable
Distance Between P2 & P3 for the corresponding
Distance Between Ceiling & Floor in the following table,
the laser must be serviced at an authorized service center.
