2.

Shut off the gun fan and atomizing air.

3.

Remove the air cap retaining ring (8), air cap (30), 
and spray tip (9).

4.

Disconnect the fluid supply hose and air supply 
hose from the gun.

5.

Connect the solvent supply hose to the gun.

6.

Increase the pressure slowly. Point the gun down 
into a grounded metal container, and flush the gun 
with solvent until all traces of fluid are removed from 
the gun passages.

To reduce the risk of serious injury, including splash-
ing fluid in the eyes or on the skin, or static electric 
discharge when flushing:
•

Ensure that the entire system, including flushing 
pails, are properly grounded.

•

Remove the spray tip.

•

Maintain metal to metal contact between the gun 
and the flushing pail.

•

Use the lowest possible pressure.

This gun is not adjustable. To ensure proper shutoff, 
screw the piston cap (27) onto the housing (1) until it 
bottoms out.

•

Flush before changing colors, before fluid can 
dry in the equipment, at the end of the day, 
before storing, and before repairing equipment.

•

Flush at the lowest pressure possible. Check 
connectors for leaks and tighten as necessary.

•

Flush with a fluid that is compatible with the 
fluid being dispensed and the equipment wetted 
parts.

•

If it is available, the flushing procedure provided 
in the pump or sprayer manual should be used 
instead of this procedure.

•

Clean the front of the tip frequently during the 
day to reduce buildup.
