2. "Trigger" the gun properly. Start
the gun moving at the beginning of
the stroke BEFORE SQUEEZING THE
TRIGGER and release the trigger
BEFORE STOPPING GUN MOVEMENT
at the end of the stroke. This
procedure will "feather" (blend)
each stroke with the next without
showing overlap or unevenness (See
Figure 8).

3. The amount of material being
applied can be varied by the speed
of the stroke, distance from the
surface and adjustment of the fluid
control knob.
4. Overlap strokes just enough to
obtain an even coat (See Figure 9).

5. Use a piece of cardboard as a shield
to catch overspray at the edges of
the work to protect other surfaces.
Use masking tape to cover other
areas if needed.
NOTE: Two thin coats of material will
yield better results and have less chance
of runs than one heavy layer.
Maintenance
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.

removing hardened materials from the
passages inside the gun.
NOTE: In the instructions below,
"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,
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
mineral spirits through the gun to
prevent corrosion.
6. Use a non-silicone oil on all moving
parts when reassembling. Use
Vaseline
threaded connections prior to
storage.
7. Clean and flush gun thoroughly
to neutralize any contaminants
corrosive to the spray gun.

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 wadded cloth 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.
