Preparing a New Sprayer
If this unit is new, it is shipped with test fluid in the fluid section
to prevent corrosion during shipment and storage. This fluid
must be thoroughly cleaned out of the system with mineral
spirits before you begin spraying.
CAUTION
Always keep the trigger lock on the spray gun in the
locked position while preparing the system.
1. Place the siphon hose into a container of mineral spirits.
2. Place the bleed hose into a metal waste container.
3. Set the pressure to minimum by turning the pressure
control knob fully counterclockwise.

Preparing to Paint

Before painting, it is important to make sure that the fluid in the
system is compatible with the paint that is going to be used.
NOTE: Incompatible fluids and paint may cause the
valves to become stuck closed, which would
require disassembly and cleaning of the
sprayer's fluid section.
CAUTION
Always keep the trigger lock on the spray gun in the
locked position while preparing the system.
1. Place the siphon hose into a container of the appropriate
solvent.
NOTE: If you are spraying a water-based latex, flush
with warm, clean water. If you are using any
other material, check with the material
manufacturer for a compatible solvent.
2. Place the bleed hose into a metal waste container.
3. Set the pressure to minimum by turning the pressure
control knob fully counterclockwise.
4. Open the hydraulic shut-off valve located on the hydraulic
pressure hose. The handle should be in line with the hose.
5. Open the bleed valve by turning it fully counterclockwise.
6. Start the engine or turn on the electric motor.

• move the choke lever to the closed position for a
cold engine or to the open position for a warm
engine,
• turn the engine switch to the ON position, and
• pull the starter rope briskly until the engine starts.

control knob fully counterclockwise,
• move the throttle lever to the slow position, and
• turn the engine switch to the OFF position.
b. To turn off the electric motor,
• set the pressure to minimum by turning the pressure
control knob fully counterclockwise,
• move the ON/OFF switch to the OFF position.
NOTE: Make sure that the spray gun does not have a
tip or tip guard installed.
10. Close the bleed valve by turning it fully clockwise.
11. Start the engine or turn on the electric motor.
12. Turn the pressure control knob clockwise approximately
1/3 of the way down to increase pressure.
13. Unlock the gun by turning the gun trigger lock to the
unlocked position.
WARNING
Ground the gun by holding it against the
edge of the metal container while
flushing. Failure to do so may lead to a
static electric discharge, which may cause
a fire.
