Flushing Guidelines
TI0307A
WARNING
FIRE AND EXPLOSION HAZARD
To reduce the risk of static sparking and
splashing when flushing, always remove
the spray tip from the gun, and hold a
metal part of the gun firmly to the side of a
grounded metal pail.
6. Start the sprayer. Keep the gun triggered until
clean solvent comes from the nozzle. Release the
trigger and engage the trigger safety latch.
NOTE: For two guns, release the trigger safety latch
on the second gun and trigger that gun until clean wa-
ter or solvent comes from the nozzle. To ensure that
the hoses are well flushed, flush the first gun and then
the second gun at least one more time.
7. Check all fluid connections for leaks. Relieve pres-
sure before tightening any connections. Start the
sprayer. Recheck the connections for leaks.
8. Remove the suction tube from the solvent pail.
Disengage the trigger safety latch. Trigger the gun
to force water or solvent from the hose. Do not let
the pump run dry for more than 30 seconds, to
avoid damaging the pump packings! Relieve pres-
sure.
9. Leave the pressure drain valve open until you are
ready to use the sprayer again. Unscrew the filter
bowl and install the clean screen. Install the bowl,
hand tight only.
10. Remove the suction tube (209) and clean it sepa-
rately to be sure all paint sediment is removed.
Dried paint in the suction tube can build up and
cause performance problems later on.
11. See Storage or Changing Colors, page 6. Relieve
pressure.
