TROUBLESHOOTING

CAUSE
Material build-up on air cap or
fluid tip. Partially plugged horn
holes, center holes or fluid tip
hole.

Not enough material.
Insufficient material.

cup or pressure tank.

packing nut.

seating properly.

Determine where material build-up
is by inverting cap and test
spraying. If pattern shape stays in
same position, the condition is
caused by material build-up on
fluid tip. If pattern changes with
cap movement, the condition is in
the air cap.
Soak cap or tip in suitable solvent
and wipe clean. To clean orifices
use a broom straw or toothpick.
Never use a wire or hard
instrument. This damages holes
and distorts its spray pattern.
