Installing AA Batteries
Load new AA batteries in the DW08302 or DW08302CG laser.
1.
Turn the laser 180° in the attached pivot bracket (Figure C
1
)..
2.
On the bottom of the laser, lift up the latch to open the battery
compartment cover (Figure C 2).
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
C 3
).
4.
Push the battery compartment cover closed until it snaps in
place (Figure C 4).
When the laser is not in use, keep the Power/Transport Lock
switch in the left (OFF) position (Figure
A 1
) to save battery
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
A 2
) to unlock the pendulum and display the three laser
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 ash, 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
prior to using the laser for the rst 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, at, 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 oor
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 oor (Figure D 1).
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 D 1).
4.
Turn the laser 180°, making sure that the down dot is still
centered over point P1 on the oor (Figure
D 2
).
5.
Mark the center of the up dot on the ceiling as point P3
(Figure D 2).
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.
Distance Between
Ceiling & Floor
Allowable Distance
Between P2 & P3
15′ (4.5m) 1/8”(3.6mm)
20′ (6m) 3/16” (4.8mm)
30′ (9m) 9/32” (7.2mm)
40′ (12m) 3/8” (9.6mm)

E
Level Dot Accuracy - Level
Checking the level calibration of the laser unit requires two
parallel walls at least 20’ (6 m) apart.
1.
Turn the laser ON to display dots above, ahead, and below,
the laser.
2.
Place the laser 2”–3” (5–8 cm) from the rst wall. Make sure
the front of the laser is facing the wall (Figure E 1).
3.
Mark the laser dot position on the rst wall as point P1
(Figure
E 1
).
4.
Turn the laser 180˚ and mark the laser dot position on the
second wall as point P2 (Figure E 2).
5.
Place the laser 2”–3” (5–8 cm) from the second wall with the
front of the laser facing the wall (Figure
E 3
).
6.
Adjust the height of the laser until the laser dot hits point
P2.
7.
Turn the laser 180˚, aim the laser dot near point P1 on the
rst wall, and mark point P3 (Figure E 4).
8.
Measure the vertical distance between points P1 and P3 on
the rst wall.
9.
If your measurement is greater than the Allowable
Distance Between P1 & P3 for the corresponding
Distance Between Walls in the following table, the laser
must be serviced at an authorized service center.
Distance Between
Walls
Allowable Distance
Between P1 & P3
20′ (6.0m) 9/32” (7.2mm)
30′ (9.0m) 7/16” (10.8mm)
50′ (15.0m) 11/16” (18mm)
75′ (23.0m) 1 1/8” (27.6mm)
Using the Laser
Operating Tips
• Always mark the center of the beam (dot) created by the
laser.
• Extreme temperature changes may cause movement of
internal parts that can affect accuracy. Check your accuracy
often while working.
• If the laser is ever dropped, check to make sure it is still
calibrated.
• As long as the laser is properly calibrated, the laser is self-
leveling. Each laser is calibrated at the factory to nd level as
long as it is positioned on a at surface within average ± 4°
of level. No manual adjustments are required.
• Use the laser on a smooth, at, level, surface.
Turning the Laser Off
Slide the Power/Transport Lock switch to the OFF/Locked
position (Figure A 1) when the laser is not in use. If the
switch is not placed in the Locked position, the laser will not
turn off.
Using the Pivot Bracket
The laser has a magnetic pivot bracket (Figure B) permanently
attached to the unit.
WARNING:
Position the laser and/or wall mount on a stable
surface. Serious personal injury or damage to the
laser may result if the laser falls.
• The bracket has magnets (Figure
B 2
) which allow the unit
to be mounted to most upright surfaces made of steel or iron.
Common examples of suitable surfaces include steel framing
studs, steel door frames, and structural steel beams.
• The bracket has a keyhole slot (Figure
B 1
) so it can be
hung from a nail or screw on any kind of surface.
