Flushing and Cleaning
1. Perform Pressure Relief Procedure, page 12.
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.
CAUTION
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.
