Preparing a New Sprayer
If this sprayer 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.
Attention
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.

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.

a. To start the gas
engine,
• move the fuel valve
lever to the open
position,
• move the throttle
lever to its middle
point,
• 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.
7. Turn the pressure control knob clockwise approximately
1/3 of the way down to increase pressure until the sprayer
cycles evenly and solvent flows freely from the bleed
hose.
8. Allow the sprayer to run for 15–30 seconds to flush the
test fluid out through the bleed hose and into the waste
container.
9. Turn off the sprayer.
a. To turn off the gas engine,
• set the pressure to minimum by turning the pressure
control knob fully counterclockwise,
• move the throttle lever to the slow position, and
• turn the engine switch to the OFF position.
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.
i
Incompatible fluids and paint may cause the valves
to become stuck closed, which would require
disassembly and cleaning of the sprayer’s fluid
section.
Attention
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.
i
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.
a. To start the gas engine,
• move the fuel valve lever to the open position,
• move the throttle lever to its middle point,
• 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.
7. Turn the pressure control knob clockwise approximately
1/3 of the way down to increase pressure until the
sprayer cycles evenly and solvent flows freely from the
bleed hose.
8. Allow the sprayer to run for 15–30 seconds to flush
the fluid out through the bleed hose and into the waste
container.
9. Turn off the sprayer.
a. To turn off the gas engine,
• set the pressure to minimum by turning the pressure
control knob fully counterclockwise,
• move the throttle lever to the slow position, and
• turn the engine switch to the OFF position.
i
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.
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.
Danger
Earth 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.
Trigger lock
in locked position.
14. Trigger the gun into the metal waste
container until the old solvent is gone and
fresh solvent is coming out of the gun.
15. Lock the gun by turning the gun trigger
lock to the locked position.
16. Set down the gun and increase the
pressure by turning the pressure control
knob slowly clockwise.
17. Check the entire system for leaks. If leaks occur, follow
the “Pressure Relief Procedure” in this manual before
tightening any fittings or hoses.
18. Follow the “Pressure Relief Procedure” in this manual
before changing from solvent to paint.
Danger
Be sure to follow the pressure relief procedure
when shutting the sprayer down for any purpose,
including servicing or adjusting any part of the
spray system, changing or cleaning spray tips, or
preparing for cleanup.
