Remove floor slope laser from packaging and insert front
fixture placement pin into hole on top and at rear of the
optical head, also there is an indentation provided for the
height adjustment screw to rest within.

Activate the laser by turning front knob clockwise
(CAUTION: Excessive turning may damage laser
ON/OFF mechanism) to assure of functionality, turn off
laser. No further adjustment is required.

NOTE: Should calibration of the laser become necessary in

the future, Refer to LASER CALIBRATION .
Calibration, Section 5.1, Pg. 9.

Laser Battery Replacement

Unscrew back of laser and replace batteries with three (3), LR 44
button batteries. Reverse process for assembly.

After battery replacement, CALIBRATION MAY BE REQUIRED.

3. OPERATION PROCEDURES

3.1 PREPARATION, ALIGNMENT BAY(s)

Prior to any headlamp alignment using the CVA 3

, the floor slope of the bay, or bays must be determined,

this is done by using the floor slope laser assembly and noting the position of the rear floor slope wheel.

If the correct floor slope of the bay is not adjusted prior to any headlamp alignment, the technician will align
the headlamps in a higher, or lower position than what is correct. The CVA 3

must be on the same plain

as the vehicle that is to be aligned, if the vehicle is positioned on a floor that has an upward slope running
from fore to aft of vehicle, then the CVA 3

must be adjusted to have the same slope.

3.2 FLOOR SLOPE MEASUREMENT

Tool Required: Tape Measure or Ruler

Move the CVA 3

to the service bay to be used for headlamp alignment and place the CVA 3

at the

front of the vehicle, off to one side. If multiple bays are to be used, procedure for determining floor slope
will need to be performed in each bay and recorded.

Lower the optical head to the bottom of the mast. Adjust optical head by rotating eccentric wheel at rear of
base until level vial registers level. Turn the laser on.

At the center point of the front wheel of the vehicle measure the distance from the floor to the point where the
laser strikes the tape measure, RECORD.

Move to the center point of the rear wheel of vehicle and measure the point where the laser strikes the tape
measure, RECORD.

If the measurements at the front and rear wheels are not equal, the bay has a slope.

Rotate the floor slope handle on rear wheel until equal
measurements are registered at the front and rear wheels.

NOTE: When rotating eccentric axle on CVA 3

, both

measurements will change at front and rear vehicle
