Troubleshooting

NOTE: Check all possible remedies in the trou-
bleshooting charts before disassembling the
gun.

Some improper patterns are caused by the
improper balance between air and fluid. Refer
to Spray Pattern Troubleshooting, page 22.

General Troubleshooting

Problem

Cause

Solution

Fluid leakage through venting
holes.

Worn packing (17) or needle (5).

Replace packing or needle.

Air leakage through venting hole.

Worn o-ring (9) or gasket (15).

Check and replace parts as
needed.

Air leakage from back of gun.

Worn o-rings (8, 9).

Replace o-rings.

Air does not trigger.

Piston stem is disconnected from
main body of piston assembly (3).

Cylinder air pressure is too low.

Replace piston assembly.

Increase cylinder air pressure to
50 psi.

Air does not shut off.

Piston assembly not seating
properly.

Broken return spring (7).

Swollen o-ring (8).

Worn piston stem o-rings (10, 11).

Bottom gasket (12) failed.

Clean/service piston assembly.
Replace worn or swollen o-rings.

Replace return spring.

Replace o-rings.

Replace o-rings.

Replace gasket.

Fluid leakage from front of gun.

Fluid needle tip (5a) is dirty, worn,
or damaged.

Dirty or worn nozzle (23).

Clean or replace fluid needle tip or
entire needle (5).

Clean or replace nozzle.

Fluid is present at air cap holes.

Nozzle (23) is insufficiently tight-
ened or sealing o-ring (36) is dam-
aged.

Tighten or replace o-ring.
