DaIly Clean-Up
Local codes may require specific
cleaning methods and equipment.
Follow local codes and manufacturer's
recommendations for the use and
disposal of spray materials and solvent.
Clean spray gun
immediately
after use. Paint and other material
dry quickly in the small passages
rendering gun useless due to the
difficulty of removing hardened paint
from the passages inside the gun.
nOte: In the instructions below, the
use of the word "solvent" refers to the
specific solvent for the material used
(eg: lacquer thinner for lacquer, etc ).
1. Spray guns with canister—Remove
and empty the canister; then rinse
with a solvent recommended for the
paint or other material used.
2. Refill canister with clean solvent
and attach to the gun. Spray solvent
through the gun while shaking
the gun vigorously. Wipe the gun
exterior with a solvent soaked rag.
Repeat until the gun is clean.
3. Remove the air cap and soak in
solvent until clean. Use a small brush
for stubborn stains if necessary.
Toothpicks or small brushes may be
used to clean air passages; however,

4. Clean gaskets with a solvent soaked
rag. To prevent equipment damage,
Do not immerse gaskets or spray
gun body in solvents.
5. After using water to clean out water
based paints or materials, spray
mineral spirits through the gun to
prevent corrosion.
6. Use a non-silicone oil on all moving
parts when reassembling. Use
Vaseline ® or light grease on all
threaded connections prior to storage.
7. Clean and flush gun thoroughly
to neutralize any contaminants
corrosive to the spray gun.
CLEANING A GUN USED WITH
A PAINT TANk
Shut off
the air
supply to the tank and
release the pressure in
the tank.
1. Open the vent on the paint tank. If
using an external mix air cap, loosen
the cap slightly.
2. Reduce air pressure to 10-20 psi. Hold
a piece of cloth, wadded in the hand,
tightly around the air cap opening(s)
and pull the trigger. The air will back
up through the fluid tip and force
the paint out of the hose and back
into the tank.
3. Pour the paint from tank and use
solvent and rags to clean.
4. Put enough solvent into the tank to
wash the hose and gun thoroughly.
Close the tank and spray from the
gun until the solvent comes out clean.
5. Remove and blow out the material
hose with compressed air to get rid
of any trace of solvent in the hose.
When blowing out
the hose, the open
end should be aimed away from any
person to avoid blowing solvent
into the eyes or on the skin causing
possible injury.
perIODIC Clean-Up
Due to improper cleaning and paint it
may be necessary to inspect and clean
the internal parts and the gun body.
1. Examine openings in air cap and fluid
tip. If clogged, remove any o-rings and
soak the air cap or fluid tip in solvent.
2. A brush or toothpick or something
similar may be used to dislodge the

3. Remove and check the adjusting
needle for excessive wear at the tip
and straightness.
ImpOrtant: If the needle tip is worn
more on one side than the other, either
the needle is bent or the gun body
has been dropped or knocked out-of-
line. There are no adjustments that
can be made to a bent gun body. Test
the needle by rolling on a flat surface.
Replace if necessary.
4. Check and replace any damaged
o-rings and seals. O-rings and seals
can be wiped clean but not soaked in
solvent.
5. Unscrew packing nuts and replace
the packing ONLY if a leak will not
stop when the nut is tightened (See
Figure 14). Do not over-tighten a
packing nut because this will restrict
movement of the needle.
6. Re-assemble in reverse order of
above and use a non-silicone oil on
moving parts. Apply Vaseline
grease on threaded joints and hose
connections.
