6. LASER CALIBRATION / MAINTENANCE
5.1 FLOOR SLOPE LASER CALIBRATION
LASER IS CALIBRATED AT THE FACTORY PRIOR TO SHIPMENT
Calibration Required ONLY if Rear- LASER Adjustment Set Screw has
been tampered with
Tools Required: Elevated Surface (wheel alignment, frame machine)
Level (carpenters level or other means)
6 Straight Edge (board or other means)
5/64 Allen Wrench
Locate an elevated surface and lay the straight edge on surface facing away from
optical head. Check straight edge for level, shim if necessary.
Move CVA 3 EZ to end of straight edge, turn on the laser and adjust height of
optical head so that the mounted laser will shoot down the straight edge.
Adjust the rear floor slope wheel until the level in the optical head is centered. Readjustment of
height of optical block may be necessary.
Adjust the rear height adjustment set screw of the laser assembly (Lock Tight has been installed
on screw at factory, minor pressure should break seal) till laser is viewed at both ends of straight
edge equally.
Laser is now calibrated, installing lock tight or other adhesive to adjustment screw is
recommended.
