Shutdown And Cleanup - Graco TexSpray EXT HP Instructions Manual

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 the following:
D A dirty filter allows contaminates into the
compressor and eventually into the pot and gun,
resulting in poor performance and damage.
D The gun requires daily lubrication for consistent
performance. See Fig. 13.
D In cold weather, store the system where it will
not freeze. If it does freeze, thaw it thoroughly
before using it.

See Fig. 14 and Fig. 15
1. Be sure the compressor pressure is relieved by
opening gun air ball valve.
NOTE: A small amount of air flow through the gun
helps to prevent material from backing up the needle
valve.
2. Partially open the gun air ball valve (R), and turn
on the ON/OFF switch (A).
3. Trigger the gun into a pail to empty the fluid in the
pot.
4. Half fill the pot (F) with clean water. Clean the
inside of the pot with a brush, if needed.
CAUTION
Flushing the hoses of the TexSpray EXT HP with hot
water weakens the hoses. A weakened hose is more
susceptible to damage and leakage. Do not use hot
water to flush the hoses.
NOTE: The pot can be removed for cleaning. See
page 7.
5. Trigger the gun into a pail until the float stop shuts
off the material flow.
6. Fill the pot with clean water, and install the lid.
7. Start the sprayer. Spray half the water into a pail.
Shut off the sprayer, and relieve the pressure.
Remove the spray gun. Close the fluid outlet valve
(H). Disconnect the hose from the coupler (43) and
install several hose cleaning balls (81) into the
hose. Reconnect the hose. Open the fluid outlet
valve (H).
8. Start the sprayer. The sprayer tank pressure
forces the hose cleaning balls and the water into
the pail. Be sure to recover the hose cleaning
balls.
Note: Use low pressure when the hose cleaning
balls are in the hose.
