locking nut. Tighten nut securely then back-off ¼ turn, or until
mast rotates freely with minor resistance.
Move glide plate up and down the mast through its full motion, by
depressing handle.
2.3 OPTICAL ALIGNMENT HEAD
Remove optical alignment head from shipping carton.
Inspect for any damage that may have occurred during
shipment i.e. lens, case, etc..
Attach optical alignment head to the mast glide plate by
aligning mounting holes of glide plate with the holes in
the optical head. Insert ¼” x 20 x ¾” allen head machine
screws through glide plate, place a ¼” x ¼” nylon spacers
on each upper screws, place a ¼” x
1 /
2
” nylon spacers on
each lower screws, attach optical head and tighten
securely.
Remove protective paper covering from viewing window
on top of optical head.
Move optical head through the full range of movement to
assure of smooth operation.
2.4 VEHICLE ALIGNMENT LINE LASER
Vehicle alignment laser assembly is enclosed in
the accessories box.
NOTE: Install batteries and secure line laser
cover per instruction that accompany
Line laser assembly.
Mount line laser assembly so that unit
is located directly over the optical head.
Insert 2, ¼” x 20 x 1 1 /
2
” screws (Small Parts
Package) into line laser calibration block and attach
all to top of mast.
DO NOT TIGHTEN. Tighten to a tension that
allows for sufficient movement during calibration.
After calibration has been performed tighten
securely.
NOTE: Line laser unit must be calibrated to the optical head
prior to alignment of headlamps.
2.5 SIGHTING UNIT CALIBRATION
Calibration of line laser unit must be performed prior to alignment
of headlamps.
Raise optical head of CVA 3 EZ EZ EZ EZ to the approximate center of
travel of mast.
Activate the line laser and turn the line laser unit until you can see
the projected laser line on the front edge of the optical head.
Projected laser line should line up with the front edge of the optical
head.
If line does not line up with the front edge of optical head, rotate
line laser assembly right or left until projected laser line is parallel
with front of optical head. Tighten screws.
It is important that periodical checking of calibration of the vehicle
alignment line laser be performed, to assure customer satisfaction.
