Volatile Organic Compounds
(VOC) Regulation
In certain states, spraying solvents that release
VOCs 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, page 6.
Maintenance
•
Frequently lubricate the gun moving
parts with a drop of non-silicone oil.
•
Do not disassemble the spray gun if you
are having a spray pattern problem. See
Troubleshooting, page 7, for information
on how to correct the problem.
•
Check for fluid leakage. Tighten fittings
or replace equipment as needed.
Flush
Flush before using the equipment, before
changing colors, and when you are done
spraying. Use solvent that is compatible with
gun wetted parts and fluid that will be sprayed.
1. Relieve pressure, page 4.
2. Dispose of any paint in the cup.
3. Fill the cup with a small amount of solvent.
4. Spray into a grounded metal waste
container until the equipment is clean.
5. Relieve pressure, page 4.
Cleaning Gun and Cup
2. Use a rag moistened in solvent to wipe
outside of gun and cup.
3. Make sure cup lid vent hole is clear.
4. Blow dry gun inside and out. Lubricate, see
Maintenance, page 5.
Cleaning Nozzle and Air Cap
1. Remove air cap (13), trigger gun, remove
nozzle (11), and soak both in a compatible
cleaning solution.
2. Clean them and the front of the gun with
a soft-bristle brush dipped into compatible
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.
Clean air line filters as directed by the
manufacturer.
See Compliant Cleaning Methods, page 6,
to comply with air quality laws if applicable.
CAUTION
•
Do not submerge gun in solvent. Solvent
dissolves lubricant, dries out packings,
and clogs air passages.
•
Do not use metal tools to clean air cap
holes as this may scratch them and distort
the spray pattern.
•
Use a compatible solvent.
See Compliant Cleaning Methods, page 6,
to comply with air quality laws if applicable.
When reassembling, make sure the
air cap matches the color etched onto
the side of the nozzle (gold, brown, grey,
blue, etc.).
