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.).
