INSTALLATION
WARNING

ront cover o this orm be ore installing, cleaning or changing
spray tips.
Install a SwitchTip spray tip in the tip guard. The flange on the
cylinder fits into the slots at the base of the tip guard.

the seat into the retaining nut and turn until it straddles the

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 amputation.
The tip guard provides extra protection against injection,
but does not prevent it! NEVER cut off the tip guard!
CAUTION
The openings in the tip guard are designed to reduce paint
buildup on the guard while sparaying. Any damage to the
sharp edges of the tip guard openings causes paint to
collect at that area, To reduce the risk of damage, do not
hang the gun by the tip guard.
Be sure the SwitchTip handle is in the FULL SPRAY position
before operating the gun.
If the spray tip clogs while spraying, engage the gun safety
latch. Turn the arrow handle to the FULL CLEAN position.
Disengage the safety latch and trigger the gun into a
grounded metal pail. Fluid pressure should force out the clog.
Engage the safety latch and return the arrow handle to the
full spray position. If it is still clogged, follow the Pressure
Relief Procedure Warning on the front of this form and
remove the SwitchTip for cleaning.
MAINTENANCE
Change the seat and gasket whenever a SwitchTip wears
out. These parts wear at about the same rate.
