Field Calibration Check
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 cali-
E
brate the laser. That is, these checks do not correct errors in the
leveling or plumbing capability of the laser. Instead, the checks indi-
cate whether or not the laser is providing a correct level and plumb
line. These checks cannot take the place of professional calibration
performed by a D
WALT service center.
E
LEVEL CALIBRATION CHECK
1. Set up a tripod 50' (15m) from a vertical wall as shown. Make
sure the head of the tripod is level using a bubble level.
2. Mount your rotary laser on the tripod so that the X-axis points
toward the wall as shown.
3. Turn the laser on, but do not put the laser in rotation mode.
4. Manually point the dot at the far wall. Mark the center of the dot
elevation on the wall.
NOTE: pointing the dot on a white surface makes marking easier.
5. Turn the entire unit 180˚ so that the X-axis points away from the
wall. Manually rotate the laser dot (or use the right /left arrows
on the remote control) so it is as close as possilbe to the first
elevation mark. Again, mark the center of the dot on the wall.
6. If the distance between the two marks is no more than 1/8"
(3.2 mm), the laser is properly calibrated.
7. Repeat the above steps for the Y-axis by pointing the Y-axis
towards the wall and then turning the laser 180˚ again.
PLUMB ERROR CHECK
1. Using a standard plumb bob as a reference, mark the top and
bottom of a wall (Be sure to mark the wall and not the floor and
ceiling.)
2. Position the rotary laser securely on the floor approximately
3' (1m) from the wall. The closer to the wall, the more accurate
this check will be.
3. Turn the laser on, and point the dot at the mark on the bottom
of the wall. Then, using the up/down arrows on the remote con-
trol, rotate the dot upwards. If the center of the dot scans over
the mark on the top of the wall, the laser is properly calibrated.
NOTE: This check should be done with a wall no shorter than the
tallest wall for which this laser will be used.
Repairs
To assure product SAFETY and RELIABILITY, repairs, mainte-
nance and adjustments should be performed by a D
service center, a D
WALT authorized service center or other
E
qualified service personnel. Always use identical replacement
parts.
