Always spray at minimum pressure with the gun nozzle tip
removed when using mineral spirits or any other solvent
to clean the sprayer, hose, or gun. Static electricity
buildup may result in a fire or explosion in the presence of
flammable vapors.
1. Follow the “Pressure Relief Procedure” found in the
Operation section of this manual.
2. Remove the gun tip and tip guard and clean with a brush
using the appropriate solvent.
3. Place the siphon tube into a container of the appropriate
solvent. Examples of the appropriate solvent are water for
latex paint or mineral spirits for oil-based paints.

OFF position.
10. Move the PRIME/SPRAY valve up to its

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.
12. Trigger the gun into the metal waste
container until the paint is flushed out
of the hose and solvent is coming out of the gun.
13.
Continue to trigger the spray gun into the waste container
until the solvent coming out of the gun is clean.
14. Follow the “Pressure Relief Procedure” found in the
Operation section of this manual.

Do not store the sprayer under pressure.
Cleaning the Spray Tip
1. Flush the gun with solvent immediately after the work is
completed.
2. Oil the sliding pins to prevent them from seizing up.
Should the spray tip become clogged, reverse
the spray tip with the lever and pull the trigger.
Once the obstruction comes out of the spray tip,
release the trigger, reverse the spray tip back to
the spray pattern setting, and resume spraying.
CAUTION
NOTE: For long-term or cold weather storage, pump
mineral sprits through the entire system.
WARNING
NOTE: Hold the return hose in the waste

General Repair and Service Notes
1. Before repairing any part of the sprayer, read the
instructions carefully, including all warnings.
Never pull on a wire to disconnect it. Pulling on a wire
could loosen the connector from the wire.

sure that the problem is corrected. If the sprayer does not
operate properly
, review the repair procedure to determine if
everything was done correctly. Refer to the Troubleshooting
section to help identify other possible problems.
3. Make sure that the service area is well ventilated in case
solvents are used during cleaning. Always wear
protective eyewear while servicing. Additional protective
equipment may be required depending on the type of
cleaning solvent. Always contact the supplier of solvents
for recommendations.
