Gasket Selection
WARNING
To
reduce the risk of fluid splashback into the eyes
or
on the skin, use the appropriate gasket as specified
in
the following text.
Use the black rubber gasket (D) ONLY with latex and
oil-based paints, stoddard solvents, mineral spirits, tur-
pentine
and water
. When using this gasket, the spray tip
can
be removed and replaced without using tools.
Use
the red or yellow plastic
gasket
(C) with the same
fluids as above and with most other solvents, including
lacquer thinner, trichloroethylene, MEK, acetone, brush
cleaner, xylol. When using this gasket, loosen the RAC
IV
retaining nut to remove the spray tip.
Installation
Relieve
pressure. Install a tip (F) so the flange (G) on
the
cylinder
fits into the slots (H) at the base of the spray tip
guard
(J). See Fig. 9.
Place
the seat (E) on a pencil, curved side out, as shown
in Fig. 10. Guide the seat into the retaining nut (A) and
turn
the seat until it
straddles the cylinder of the spray tip
(F).
Drop
in the appropriate gasket and press it down. If
using the red or yellow gasket (C), be sure the flat side
faces
out of the retainer (A). See Fig. 9.
Screw the spray tip guard snugly onto the gun, holding
it
in the desired position
while tightening the retaining nut
(A).
NEVER
use a wrench to turn the plastic tip guard (J),
to
avoid
damaging the guard.
Operation
WARNING
Keep clear of nozzle! High pressure fluid from leaks
or
spray can penetrate the skin and cause extremely
serious bodily injury, including the need for amputa-
tion. the spray tip guard provides extra protection
against
injection,
but does not prevent it!
NEVER cut
off
the spray tip guard!
Be
sure the spray tip handle is in the FULL SPRA
Y posi
-
tion
before operating the gun. See Fig. 9.
Clearing a Clogged Spray Tip
Disengage the trigger cable(s). Engage the gun safety
latch. Turn the arrow handle to the FULL CLEAN posi-
tion.
See Fig. 1
1. Release the safety latch and trigger the
gun.
Fluid pressure should force out the
clog. Return the
arrow handle to the full spray position.
If it is still
clogged
, follow the Pressure Relief Procedure on
page
4 and remove the spray tip for cleaning.
Maintenance
Change the seat and gasket when the spray tip wears
out;
these parts wear at about the same rate.
