Flushing and Cleaning

Maintenance

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.
