ment unless it is replaced. If a line is tracking poorly,
check for the following items before aligning the
caster.
1. Even back tire pressure.
2. Even tension on the rear tire bearings (adjust
nuts (10) as needed). See page 42.
3. Even tightness of caster setscrews (F). See
Fig. 16.
4. Uneven painting surface.
5. Operator technique.

the gun's trigger safety latch (B).
3. Loosen the gun holder knob (93).

How To Mount the Gun

Caster Tire Replacement
Remove the setscrews (F) from the caster fork (E). Re-
move screw (G) and the tire (1 14a). Install the new tire
and the setscrews (F). Tighten the setscrews equally so
the tire has no play in it, but turns freely.
Caster Cable Tension Adjustment
16.
1. Loosen the nut (A) located just outside the carriage
clamp (B).
2. With the pin (D) fully engaged in the caster fork (E),
pull back on the cable (2) to increase the cable ten-
sion, or push it forward to reduce the tension. Finger
tighten the nut (H). Tighten the nut (A) firmly.

Caster Alignment
Do this adjustment only if the caster or tire is replaced,
or if no other solutions to poor tracking are found.
1. Loosen the two capscrews (87), grasp the tire visual-
ly align the tire. Tighten the capscrews evenly. Move
the unit forward. If the caster appears straight, start
the unit (use water) and spray along a true straight
line. Continue adjusting as necessary. See Fig. 16.
