3. 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 10).

4. The amount of paint being applied
can be varied by the speed of the
stroke, distance from the surface and
adjustment of the fluid control knob.
5. Overlap strokes just enough to
obtain an even coat (See Figure 11).

NOTE: Two thin coats of paint will yield
better results and have less chance of
runs than one heavy layer.
6. 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.

other materials 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 spe-
cific solvent for the material used (exam-
ple: lacquer thinner for lacquer, etc.).
1. Remove and empty the canister;
then rinse with a solvent recom-
mended for the paint or other

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 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.

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 sur-
face. Replace if necessary.
