3. Close the pressure drain valve (D).
4. Pour 2 liters of compatible solvent into a grounded
metal pail. Put the suction tube in the pail.
5. Remove the spray tip from the gun.
Flushing
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, and aimed into, a grounded metal pail.
6. Disengage the gun safety latch. Point the spray gun
into a metal waste container. With a metal part of the
gun firmly touching the metal container, squeeze the
gun trigger. See Fig. 9. This procedure helps reduce
the risk of static sparking and splashing. Start the
sprayer, trigger the gun, and slowly turn the pressure
adjusting knob clockwise, just until the pump starts.
Keep the gun triggered until clean solvent comes
from the nozzle. Release the trigger. Engage the gun
safety latch.
7. Check all fluid connections for leaks. If any connec-
tions leak, first relieve the pressure. Tighten the
connections. Start the sprayer. Recheck the connec-
tions for leaks.
8. Remove the suction tube from the pail. Disengage
the gun safety latch. Trigger the gun to force solvent
from the hose. Do not let the pump run dry for more
than 30 seconds, to avoid damaging the pump pack-
ings! Relieve the pressure.
9. Leave the pressure drain valve open until you are
ready to use the sprayer again. Unscrew the filter
bowl and reinstall the clean screen. Reinstall the
bowl, hand tight only.
10. If you flushed with mineral spirits and are going to use
a water–base paint, flush with soapy water followed
by a clean water flush. Relieve the pressure.
