Special cleanup

IMPORTaNT: Perform the following procedure after
spraying with water-based materials only.
Perform the following procedure when the valves of the sprayer
are stuck or when preparing the sprayer for long term storage.
The use of a pump cleaning adapter that attaches to the bottom
of the siphon tube is required (the pump cleaning adapter is
included with the sprayer).
1. Lock the gun and remove the spray tip assembly. If
necessary, loosen the gun holder clamp knob and then
engage the spray gun trigger lock. Move the spray gun
to its original position and tighten the clamp knob. Place
the suction tube and return tube into an empty waste
container.
2. Using a garden hose, rinse off the siphon tube, return
hose and inlet filter. Empty the waste container.
3. Remove the inlet filter
from the suction tube
and place into a waste
container.
4. Verify that the seals
are present inside the
adapter and suction
tube. Thread the pump
cleaning adapter onto a
garden hose. Connect
the hose and adapter to
the fitting on the end of
the siphon tube.
5. Unclip the return hose
from the siphon tube and
place it into the waste
container.
6. Turn the PRIME/SPRAY knob to the PRIME position.
7. Turn on the water supply.
8. Start the engine. Water will go into the siphon tube and
out through the return hose. Let the sprayer run for a few
minutes to allow the return hose to be flushed.
9. Turn off the sprayer by pressing and holding the engine
shutoff switch until the motor shuts off.
10. Place a metal waste container underneath the spray gun
to catch the cleaning solution.
11. Start the engine.
12. Turn the PRIME/SPRAY knob to the SPRAY position.
13. Fully pull the spray lever on the cart handle to rev the
engine, pressurize the sprayer, and trigger the spray gun.
Fluid will begin flowing through the spray hose and out of
the gun.
14. Continue to pull the spray lever on the cart handle until the
material is flushed out of the hose and the water coming
out of the gun is clean.
15. Release the spray lever.
16. Follow the "Pressure Relief Procedure" found in the
Operation section of this manual.

cleaning/Replacing the Gun Filter

The gun filter must be cleaned after every use of the sprayer.
When using thicker spray materials, the filter might need to be
cleaned more often.

section of this manual.
2. Unscrew the fitting from the bottom of the spray gun using
an adjustable wrench, making sure not to lose the spring.
3. Remove the filter from the spray gun housing and clean
with the appropriate cleaning solution (warm, soapy water
for latex paints, mineral spirits for oil-based materials).
4. Inspect the filter for holes. Replace if holes are found.
