WARNING
To reduce the risk of fluid injection or splashing in the
eyes or skin, completely relieve fluid pressure before
installing, cleaning or changing tips. See the Pres-
sure Relief Procedure on page 4.
WARNING
Failure to install or use the RAC IV tip guard assembly
correctly may result in an undirected spray of paint
into the eyes or on the skin of the operator. Be sure
you:
Use the appropriate gasket for the solvent used.
Fully insertipt the into the guard.
Fully tighten the guard onto the gun nozzle using
a wrench.
Turtipn the handle so it is parallel to the gun
nozzle.
When replacing a worn spray tip, always install a
new gasket and seat.
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.
Spray Tip and Tip 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 SPRAY 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. 11. Release the safety latch and trigger the
gun. Fluid pressure should force out the clog. Return the
arrow handle to the full spray position.
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.
