Cleaning and Maintenance

NOTE:

Clean air line filters as directed by the manufac-

turer.

Volatile Organic Compounds 
(VOC) Regulation

In certain states, spraying solvents that release VOC’s
into the atmosphere when cleaning a spray gun is
prohibited. To comply with these air quality laws you
must use a cleaning method that prevents the escape of
VOC vapors into the atmosphere. See

Compliant 

Cleaning Methods

below.

Compliant Cleaning Methods

Place spray gun in a gun washer that completely
encloses the gun and components during cleaning,
rinsing, and draining.

Spray solvent through the spray gun into a closed
gun cleaning station.

Cleaning Gun and Cup

NOTE:

Refer to

Compliant Cleaning Methods

to

comply with air quality laws if applicable.

1.

Follow

Flushing

procedure, page 4.

2.

Use a rag moistened in solvent to wipe outside of
gun and cup.

3.

Blow dry gun inside and out. Lubricate gun as
described in

Spray Gun Maintenance

.

Cleaning Nozzle and Air Cap

To clean the air cap and nozzle, remove and
soak them in a compatible cleaning solution.
Clean them and front of gun with a
soft-bristle brush dipped into compatible
solvent. Do not use a wire brush or metal
tools. To clean out air cap holes, use a soft
implement, such as a toothpick.

Spray Gun Maintenance

Frequently lubricate the gun moving parts with a
drop of non-silicone oil (part no. 8255).

Do not disassemble the spray gun if you are having
a spray pattern problem. Check

Troubleshooting

,

page 6, for information on how to correct the prob-
lem.

Check for fluid leakage. Tighten fittings or replace
equipment as needed.

NOTICE

Do not submerge gun in solvent. Solvent dissolves
lubricant, dries out packings, and may clog air pas-
sages.

Do not use metal tools to clean air cap holes as this
may scratch them and distort the spray pattern.

Use a compatible solvent.

Gun can be cleaned in a gun washer.

NOTICE

Trigger gun whenever you tighten or remove nozzle
to avoid damaging needle seat and nozzle.

Do not use metal tools to clean air cap holes as this
may scratch them and distort the spray pattern.
