WARNING
INJECTION HAZARD
Be sure your system has a bleed–type
master air valve (pneumatic pumps only)
and a fluid drain valve. These two ac-
cessories help to reduce the risk of a serious injury,
including fluid injection or splashing in the eyes or
on the skin, or injury from moving parts, if you are
adjusting or repairing the pump or gun.
Basic Guidelines
The bleed–type master air valve relieves air trapped
between this valve and the pump after the air regulator
s shut off. Trapped air can cause the pump to cycle
unexpectedly.
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.
NOTE: Whenever you stop spraying for a
moment, engage the gun safety latch. See Figure

1. Connect the grounded fluid hoses to the gun inlets.
2. With no tip installed, start the pump/sprayer. Flush
it according to the instructions supplied with it.
Prime the sprayer with the fluid you are using.
3. Follow the Pressure Relief Procedure described on
page 7.
4. With the gun safety latch engaged, unscrew the tip
guard (23) and install the tip and gasket (51) in the
back of the tip guard. Screw the assembly firmly
onto the mixer. Install o–ring (10) into nut of the
mixer. Screw and assemble firmly onto the gun.
Tighten both connections with a wrench. See
Figure 2.
NOTE: Failure to install the tip gasket (51) when
using a flat tip (only) will result in leaking.
5. Strain the fluid you are spraying if it contains
particles which could clog the spray tip.
