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 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
Possible Cause(s)
1.
Holes in left or right side of the air cap are
plugged
2.
Dirt on left or right side of fluid tip
1.
Dried material at top or bottom of fluid
tip
2.
Loose air cap or dirty seat
3.
Air cap plugged
1.
Fan pattern open too far
2.
Fluid turned in too far
3.
Atomization air too high
4.
Fluid pressure too low (pressure feed only)
1.
Fan adjustment partially closed
2.
Material too thick
3.
Atomization pressure too low
4.
Fluid pressure too high (pressure feed)
Figure 6). 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
light grease on threaded joints and
hose connections.
STORAGE
1. When not using spray gun,
turn the fluid adjustment knob
counterclockwise to open which will
reduce spring tension on needle fluid
tip.
2. Spray gun mUST BE well cleaned and
lightly lubricated.
