Symtech CVA 3 With Line Laser - Manual (Page 8)

8
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 EZ EZ EZ EZ , both
measurements will change at front and rear vehicle
wheels, to achieve equal measurements, more than one
eccentric axle change may be required.
Note the number on the floor slope gauge and record that number along with the bay
designate on floor slope sticker provided. Repeat procedure for other bays and record.
NOTE: After measurements have been taken, remove laser and store in a secure place
3.3 VEHICLE PREPARATION
•
Remove ice or mud from under the fenders.
• Set the tire inflation to the values recommended by the manufacturer.
• See that there is no load in the vehicle unusual to normal driving conditions.
• Check vehicle springs for sag or broken leafs.
• Check function of any automatic leveling systems and specific manufacturers instructions
pertaining to vehicle preparation for headlamp alignment.
• Clean lenses, check for bulb burnout, broken mechanical aiming pads, moisture in lens and
proper beam switching.
• Stabilize suspension by rocking vehicle sideways.
4. HEADLAMP ALIGNMENT
4.1 ALIGNMENT OF OPTICAL HEAD TO VEHICLE
Place the CVA 3
EZ EZ EZ EZ in front of the first headlamp to be aligned.
Once the CVA 3 EZ EZ EZ EZ is in place, the lens of the optical head
should be approximately 12 inches (+/- 6 inches) from the face of
the headlamp.
Set the floor slope of the eccentric wheel for the bay in which the
vehicle has been parked.
Rotate the vehicle alignment line laser so that the projected laser
line can be seen on the front of the vehicle. Locate two (2) common
points on or under the hood to align the projected laser line.
NOTE: Points can be hood stops, radiator supports, points of
fender, etc.
While observing laser line, align the projected laser line on the two
common points by rotating the optical head.
The CVA 3 EZ EZ EZ EZ is now aligned with the vehicle. Repeat the
alignment process for each lamp.
4.2 CENTERING on the HEADLAMP
Turn headlamps on. Move optical head up, or down to the center of the
headlamp. Position of center of the headlamp is approximate; a ± 2”
allowance is acceptable.
TRICK: A method to determining if position is greater than 2” is by observing
the “Visual Assist” meter for highest reading while moving CVA
