Strain the Paint

Disposable paint strainer bags are used to
remove coarse particles and debris from
new or previously opened paint or stain,
and are available where paint is sold. To
avoid priming problems and Spray Tip
clogs it is recommended to strain all paints
and stains before spraying. Stretch a dis-
posable paint strainer bag over a clean pail
and pour the paint through the strainer.

Fill Pump (Prime Pump)

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.
1. Move Suction Tube to paint pail and
submerge Suction Tube in paint.
2. Turn ON/OFF switch to ON position.
3. Wait to see paint coming out of Drain
Tube.
4. Turn ON/OFF switch to OFF position.
NOTE: If paint does NOT flow up the Suction
Tube and out the Drain Tube, see Flush
Storage Fluid, page 16.
