General Description
This piston pump is a precision power tool used for spraying
many types of materials. Read and follow this instruction
manual carefully for proper operating instructions,
maintenance, and safety information.
Operation
This equipment produces a fluid stream at extremely high
pressure. Read and understand the warnings in the
Safety Precautions section at the front of this manual
before operating this equipment.
Pre-Start
Perform the following procedure before starting the gas
engine.
1. Ensure that the suction set and the return hose are
attached and secure.
2. Attach a minimum of 50’ of airless spray hose to the unit.
3. Attach an airless spray gun to the spray hose. Do not
attach the tip to the spray gun yet. Remove the tip if it is
already attached.
Make sure all airless hoses and spray guns are
electrically grounded and rated for at least 3200 psi (220
bar) fluid pressure.
4. Turn the pressure control knob fully
counterclockwise to its lowest pressure
setting.
5. Make sure the engine ON/OFF switch is
in its OFF position.
6. Fill the wet cup with one tablespoon of
Piston Lube.
Never operate unit for more than ten seconds without
fluid. Operating this unit without fluid will cause
unnecessary wear to the packings.
7. Check the engine oil level. The gasoline engine oil level
is determined by the manufacturer. Refer to the engine
manufacturer's service manual (supplied).
8. Close the fuel shut-off lever and fill the gas tank with
gasoline. Use only high quality, unleaded gasoline.

Purging and Priming
Always keep the trigger lock on the spray gun in the
locked position while purging the system.
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 before you
begin spraying.
If it is already in service, you will need to purge the water or
solvent used in cleanup.
Purging and Priming the Pump for Latex Paint
1. Secure the return hose into a waste container.
2. Place the suction tube into a container of the appropriate
solvent.
3. Turn the pressure control knob fully counterclockwise its
lowest pressure setting.
4. Turn the PRIME/SPRAY valve down to the PRIME
position.
5. Move the pump ON/OFF switch to the ON position.
6. Move the engine ON/OFF switch to the ON position.
7. Start the engine:
a. Open the fuel shut-off
lever.
b. Move the throttle lever
away from the gas tank.
c. Close the engine choke
lever.
d. Holding the frame with
one hand, pull the starter rope rapidly and firmly.
Continue to hold the rope as you let it return. Pull and
return the rope until the engine starts.
8. Slowly turn the pressure control knob clockwise to
increase the pressure until fluid starts to come out of the
return hose. Use only enough pressure to keep the fluid
coming out.
9. Turn the pressure control knob fully counterclockwise to
its lowest setting when the test fluid is purged and solvent
is coming out of the return hose.
10. Remove the container of solvent from the suction tube
and replace it with a bucket of clear water.
11. Increase the pressure to the minimum necessary to keep
fluid flowing until clear water is coming out of the return hose.
12. Turn the pressure control knob fully counterclockwise to
its lowest setting.
13. Remove the bucket of water from under the suction tube
and replace it with a container of latex paint.
14. Increase the pressure slowly until paint is coming through
the return hose.
15. Remove the return hose from the waste container and
place it in its operating position above the container of
latex paint.
16. Keep circulating the paint through the system until the
paint coming out of the return hose is free of air bubbles.
17. Turn the pressure control knob fully counterclockwise to
its lowest setting.
The pump is now purged. Skip to
Purging and Priming the
Spray Hose.
Purging and Priming for Solvent-Based Paint
1. Secure the return hose into a waste container.
2. Place the suction tube into a container of the appropriate
solvent.
3. Turn the pressure control knob fully counterclockwise to
its lowest pressure setting.
4. Turn the PRIME/SPRAY valve down to the PRIME
position.
