Shutdown and Cleanup

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.
Oil the gun daily.
Oil the pump air inlet. See Pump Maintenance in
the Texture Pump Manual 308–399.
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. 12.
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. 11.
12. When the unit cools, rinse the cooler with plain
water.
