Operating Instructions
Maintenance (cont.)
NOTE: In the instructions below, the use
of the word "solvent" refers to the spe-
cific 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 exteri-
or with a solvent soaked rag. Repeat
until the gun is clean.
3. Remove the air cap and soak in sol-
vent until clean. Use a small brush
for stubborn stains if necessary.
Toothpicks or small brushes may
be used to clean air passages; how-
ever, NEVER USE METAL OBJECTS
TO CLEAN PRECISELY DRILLED
PASSAGES. DAMAGED PASSAGES
WILL CAUSE IMPROPER SPRAYING.
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 min-
eral spirits through the gun to pre-
vent corrosion.
6. Use a non-silicone oil on all mov-
ing 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 corro-
sive 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 sol-
vent 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 per-
son 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
dried paint from holes and passages.
NEVER USE METAL OBJECTS
TO CLEAN PRECISELY DRILLED
PASSAGES. DAMAGED PASSAGES
WILL CAUSE IMPROPER SPRAYING.

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 nee-
dle 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 or light grease
®
on threaded joints and hose connec-
tions.
STORING
1. When not using spray gun, turn
the fluid adjustment knob counter-
clockwise to open which will reduce
spring tension on needle fluid tip.
2. Spray gun MUST BE well cleaned
and lightly lubricated.
