Know Your Controls
Know Your Controls
The ON/OFF power switch controls the main
power to your sprayer.
The Pressure Control knob increases or
decreases the pressure and flow of the paint.
The Prime/Spray Valve directs the fluid to
either the Drain Tube or the hose and gun. It
is used to prime the sprayer, which means to
evacuate the air out of the pump, hose, and
gun.
Your gun will not spray if there is air in the
system. It is necessary to prime the pump,
hose, and gun any time air enters the Suction
Tube.
The Spray Tip is the key to airless spray
technology. High pressure paint pumped
through the very small hole in the Spray Tip
comes out as a spray.
The Spray Tip has the ability to be reversed
and quickly clear clogs.

High-pressure spray is able to inject toxins
into the body and cause serious bodily
injury. Do not stop leaks with hand or rag.
NOTE: Inspect for leaks. If leaking occurs,

Pump (Prime Pump), page 16.

Refilling Paint Pail
When the paint pail runs low and the gun
stops spraying, refill the paint pail and repeat
the Fill Pump (Prime Pump) procedure,
then the Fill Gun and Hose procedure.
You are now ready to spray!
NOTE: It is normal for the motor to stop once
the sprayer is primed and under pressure. If
the motor continues to run, the sprayer is not
primed. Repeat the Fill Pump (Prime Pump)
and Fill Gun and Hose processes.
