Symtech SCA 1 With Line Laser - Manual (Page 6)

Place a thick nylon bushing on the screw and insert
screw through the holes provided at the top of the
mast, place a thick nylon bushing on screw and self-
locking nut.
Tighten to a tension that allows for movement of
sighting unit, but provides sufficient friction to hold
unit in place when unattended.
NOTE: The mast has two sight unit mounting positions, mount in
the position that is most comfortable for the technician to
sight through
Sighting unit must be calibrated to the optical head prior
to alignment of headlamps.

2.5 SIGHTING UNIT CALIBRATION
Calibration of sighting unit must be performed prior to alignment of
headlamps.
Raise optical head of SCA 1
ISOColor to the approximate center of
mast.
Turn the sighting unit until you can see the front edge of the optical
head while looking through the sighting unit lens. Line on lens
should line up with the front edge of the optical head.
If line does not line up with the front edge of optical head, loosen
the thumbscrews on the lens and move the lens into alignment.
Tighten thumbscrews.
It is important that periodical checking of calibration of the sighting
unit be performed, to assure proper calibration.
NOTE: When technicians of differing heights are using the SCA 1
ISOColor and the sighting unit is relocated to the optional
mounting position for better viewing, the sight unit must be
checked for calibration and adjustment made accordingly.
2.6 FLOOR SLOPE LASER
