Operating Instructions and Parts Manual HVLP Gravity Feed Spray Gun
in motion while spraying. Stopping
gun movement in mid-stroke will
cause a build up of paint and result
in runs. Do not fan the gun from
side to side while painting. This will
cause a build-up of paint in the cen-
ter of the stroke and an insufficient
coating at each end (See Figure 9).
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 MOVE-
MENT 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.
Maintenance
DAILY CLEAN-UP
Local codes may require specific clean-
ing methods and equipment. Follow
local codes and paint manufacturer’s
recommendations for the use and dis-
posal of spray materials and solvent.
Clean
spray gun
immediately after use. Paint and other
materials dry quickly in the small pas-
sages 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
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 exte-
rior 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; however,
NEVER USE METAL OBJECTS TO
CLEAN PRECISELY DRILLED PAS-
SAGES. 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
®
or light grease on all thread-
ed connections prior to storage.
7. Clean and flush gun thoroughly to
neutralize any contaminants corro-
sive to the spray gun.
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 pas-
sages. NEVER USE METAL
OBJECTS TO CLEAN PRECISELY
DRILLED PASSAGES. DAMAGED
PASSAGES WILL CAUSE IMPROP-
ER SPRAYING.
3. Remove and check the fluid 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 5). 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 connections.
STORING
1. When not using spray gun, turn the
fluid adjustment knob counterclock-
wise to open which will reduce
spring tension on needle fluid tip.
2. Spray gun MUST BE well cleaned
and lightly lubricated.
