Daily Gun Maintenance

Clean Nozzle and Air Cap
1. Remove air cap (13), trigger gun, remove
nozzle (11), and soak both in a compatible
cleaning solution.
2. Clean air cap, nozzle, and front of the gun
with a soft-bristle brush dipped into com-
patible solvent. Do not use a wire brush or
metal tools.
3. Use a soft implement, such as a toothpick,
to clean out air cap holes.
4. Trigger the gun while you install the fluid
nozzle with the gun tool. Tighten the nozzle
securely to 155-165 in-lb (17.5-18.6 N•m)
to obtain a good seal.
5. Install the retaining ring (14) and
air cap (13).
6. After cleaning the gun, lubricate the follow-
ing parts with lubricant 111265 daily:
• fluid control valve threads
• trigger pivot pin
• fluid needle shaft
Compliant Cleaning Methods
1. Place spray gun in a gun washer that com-
pletely encloses the gun and components
during cleaning, rinsing, and draining.
2. Spray solvent through the spray gun into
a closed gun cleaning station.
CAUTION
Trigger the gun whenever you tighten or
remove the nozzle. This keeps the needle tip
away from the nozzle seating surface and
prevents the tip from being damaged.
When reassembling, make sure the
air cap matches the color etched onto
the side of the nozzle (gold, brown, grey,
blue, etc.).
