WARNING
Be sure your system has a bleed-type master air
valve (pneumatic pumps only) and a fluid drain
valve. These two accessories help reduce the risk
of serious injury, including fluid injection, splashing
in the eyes or on the skin, or injury from moving
parts, if you are adjusting or repairing the pump or
gun.
D The bleed-type master air valve relieves air
trapped between this valve and the pump after
the air regulator is shut off. Trapped air can
cause the pump to cycle unexpectedly.
D The fluid drain valve assists in relieving fluid
pressure in the displacement pump, hose, and
gun; triggering the gun to relieve pressure may
not be sufficient.
1. Connect a grounded fluid hose to the gun inlet.
2. With no tip installed, start the pump/sprayer. Flush
it according to the instructions supplied with it.
Prime the system with the fluid you are using.
3. Relieve the pressure.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 6.
Installation
4. With the gun safety latch engaged, unscrew the
retaining nut (B) of the tip/guard assembly
(18, 28), and install the gasket (28a) in the
retaining nut. Screw the tip/guard assembly firmly
onto the gun. Tighten with a wrench. See Fig. 1.
NOTE: Failure to install the tip gasket (28a) will
result in leaking.
5. Strain the fluid you are spraying if it contains
particles that could clog the spray tip.
