Detail Spray Gun
3. Remove the air cap and soak in solvent
until clean. Use a small brush for stub-
born 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 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.
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 sol-
vent.
5. Unscrew packing nuts and replace
the packing ONLY if a leak will not
stop when the nut is tightened.
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 counter-
clockwise to open which will reduce
spring tension on needle fluid tip.
2. Spray gun MUST BE well cleaned
and lightly lubricated.
