WARNING
To reduce the risk of static sparking and splashing,
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 when flushing.
6.
Point the spray gun into a grounded metal pail, and
with a metal part of the gun firmly touching the metal
container, squeeze the gun trigger. This procedure
helps reduce the risk of static sparking and
splashing. With the gun triggered, turn the ON/OFF
switch to ON and slowly turn the pressure adjusting
knob clockwise

the gun triggered until clean solvent comes from the
nozzle.

page 2. Tighten the connections, start the sprayer,
and check to be sure the leaking has stopped.
10. Remove the suction tube from the pail. Disengage
the gun safety latch and trigger the gun into a
grounded metal pail to force solvent from the hose.
Do not let the pump run dry for more than 30 sec-
onds to avoid damaging the pump packings!
