patible flushing fluid.

the parts.

intake from the original pail. Put the pump intake in
a grounded pail of compatible solvent.

5. Single component systems only: Trigger the gun
into the original pail. When flushing fluid appears,
release the trigger.

pail. Circulate the fluid until the system is thoroughly

To reduce the risk of serious injury, including splashing
fluid in the eyes or on the skin, or static electric dis-
charge when flushing:
Be sure the entire system, including flushing pails,
is properly grounded.
Remove the tip guard and spray tip.
Maintain metal to metal contact between the gun
and the flushing pail.
Use the lowest possible pressure.

fluid cures.
