Preparation
Operation Characteristics
D Always start the system with the compressor air
relieved.
D Air bleeds from the gun nozzle whenever the gun
air ball valve (R) is open. Close the gun air ball
valve to stop the air, if desired. See Fig. 8. See
Spraying Techniques on pages 12 and 13 for
more gun characteristics.
D A compressor unloader valve (M) with two pressure
relief valves (W) is located under the compressor
guard (11). Air escapes from the valve, often
causing a popping sound, when air flow at the gun
is too restricted. The valve resets automatically
when the air flow is increased. See Fig. 9.
WARNING
The motor has a thermal overload switch that shuts
down the motor if it overheats.
To reduce the risk of serious bodily injury due to the
system restarting unexpectedly, always turn the
ON/OFF switch (A) OFF if the motor shuts down.
See Fig. 7.
CAUTION
Damage to the power cord may result from uninter-
rupted operation. Do not operate sprayer at maxi-
mum pressure for more than 1 hour in any 2 hour
period.
