SERVICE CHECK
Normal Spray Pattern
The proper combination of fluid pressure, fan and atomization air pressure,
and fluid tip size should result in a pattern of this shape.
PROBLEM CAUSE CORRECTION
Will not spray. No pressure to gun.
Piston stops moving.
Check air and material lines.
Check CYL air pressure.
A. Gun not adjusted properly.
A, B Material build up on the air
cap (2)or fluid tip (3).

Section”.

See “Preventive Maintenance”.
Note
To determine where the material build up is, rotate the air cap 180 and test
spray. If the pattern stays in the same position, the condition is caused by
material build up on the fluid tip. If the pattern changes with air cap movement,
the build up is in the air cap.
