• Mount your Rotary Laser on a tripod so it is aimed front-to-back

toward the vertical surfaces. (next page)

• Level the Laser, following the procedure in the “Horizontal

Leveling” section of this manual.

• Quick Check:

1. Compare the position of the bubbles in the front and rear vials

(Fig. AA).

2. If the two bubbles are not in about the same position in their

vials, (both about centered) have your Rotary Laser calibrated
at a D

WALT service center.

• Turn the unit on so that the lasers are on and rotating.
• Go to surface #1 and mark the center of the beam. If it is difficult

to see the beam, use your Laser Enhancement Glasses, Target
Card or optional DW0732 Digital Laser Detector.

• Go to surface #2 and mark the center of the beam.
• Loosen the screw holding the Laser to the tripod, but do not

remove the Laser.

• Rotate the Laser 180˚ (Fig. BB)
• Level the Laser again, following the procedure in the “Horizontal

Leveling” section of this manual.

• Turn the unit on if it is not already on, so the lasers are on and

rotating.

• Go to surface #1 and mark the center of the beam.
• Go to surface #2 and mark the center of the beam.
• Measure the difference between the marks on surface #1.
• Measure the difference between the marks on surface #2.
• The difference between the marks on surface #1 must equal the

difference between the marks on surface #2. If these are not
equal, there was user set up or marking error.

• If the difference between the marks on surface #1 is 1/4" or less,

the Laser is properly calibrated.

• If the difference between the marks on surface #1 is more than

1/4", have your Rotary Laser calibrated at a D

WALT service

center.

HORIZONTAL CHECKING FOR SIDE-TO-SIDE TILT ERROR

• Set up tripod midway between 2 vertical surfaces 100' from each

other.

toward the vertical surfaces.

• Level the Laser, following the procedure in the “Horizontal

Leveling” section of this manual.

• Turn the unit on so that the lasers are on and rotating.
• Go to surface #1 and mark the center of the beam. If is difficult to

see the beam use one of the aids mentioned earlier.

• Go to surface #2 and mark the center of the beam.
• Loosen the screw holding the Laser to the tripod but do not

remove the Laser.
