1. Fig. 13. and 14. Be sure the compressor pressure
is relieved – gun air valve (423) open. Close the
gun air valve again. Turn the ON/OFF switch (D)
ON.
2. Trigger the gun into a pail to lower the fluid to the
hopper strainer (L) level. See Fig. 14.
3. Fill the hopper (J) about half full with clean water,
depending on the hose length. Clean the inside of
the hopper with a brush, if needed.
NOTE: The hopper can be removed for cleaning. See
page 5.
4. Trigger the gun into a pail until most of the texture
material is pumped out.
5. Fill the hopper with clean water.
6. Start the sprayer. Spray half the water into a pail.
Trigger the gun into the hopper to circulate the
remaining water for a few minutes.
7. Trigger the gun into the pail to empty the hopper
and the hose.
8. Turn the ON/OFF switch (D) OFF. Open the gun
air valve (423) to relieve compressor pressure.
See Fig. 13. and 14.
9. Keep pump wet during non-use. Pour 12 oz.
(360 ml) of clean water into the hopper drain.
CAUTION
To keep the unit in good operating condition, always
clean it thoroughly and prepare it properly for
storage, even for overnight storage. Pay particular
attention to these areas:
Keep the pump wet during non-use to help
prevent contaminants from drying inside the
pump.
Clean the sponge filter at least daily. A dirty filter
allows contaminates into the compressor and
eventually into the pump, resulting in poor perfor-
mance and damage.
Removing the material hose will allow the pump
to drain rapidly. The material hose must remain
connected to keep the pump wet.
Oil the gun daily.
Oil the pump air inlet. See Pump Maintenance in
the Texture Pump Manual 308–781.

Shutdown and Cleanup
NOTE: In cold weather, store the system where it will
not freeze. If it does freeze, thaw it thoroughly before
using it.
10. Remove the air filter (21), wash it thoroughly with
soap and water, and reinstall it. See Fig. 14.
11. Clean and dry the gun. Oil the gun daily with a few
drops of SAE–10 light oil at the points indicated in
Fig. 13.
12. When the unit cools, rinse the cooler with plain
water.
NOTE: Keep the pump and hose clean when switching
between texture, knockdown and orange peel. A dirty
pump can release a piece of texture into the finish.
13. Drain the frame air line after each use.
a. Open the drain cock valve (S). See Fig. 14.
b. Turn the ON/OFF switch ON.
c. Rock the sprayer back and forth slightly to
drain any moisture in the air line.
d. Turn the ON/OFF switch OFF.
e. Close the drain cock valve.
