MAINTENANCE

Daily Care and Cleaning

CAUTION

Clean all parts with a non±conductive solvent, compatible with the fluid being sprayed. Conduc- tive solvents can cause the gun to malfunction.

Do not use any cleaning method which may al- low solvent into the gun air passages. Solvent left in the gun passages could result in a poor qual- ity paint finish and may draw current and reduce the electrostatic effect. Point the gun down while cleaning to prevent dirty solvent from running back into the air passages. NEVER IMMERSE THE

GUN IN SOLVENT.

WARNING

For your safety, always follow the Pressure Relief Procedure Warning on page 9 when shutting off the system, when you stop spraying, and before checking, servicing, installing, cleaning or chang- ing any part in the system.

1.Clean the fluid and air line filters daily.

2.Check all of the work hangers for build-up of material; clean them, if necessary.

3.All loose or ungrounded objects must be removed from the spray booth.

4.Clean the outside of the gun daily with a soft cloth dampened in a compatible solvent.

5.Flush the spray gun before changing fluids or colors and whenever you are done operating the gun. See Flush the Spray Gun.

6.Check the electrode wire. Straighten if bent, and re- place if broken or damaged. See Electrode Replacement.

7.Clean the air cap and spray nozzle daily, minimum; some applications require more frequent cleaning. Replace the spray nozzle and air cap if they are dam- aged. See To Clean or Change Air Cap and Fluid

Nozzle.

Flush the Spray Gun

WARNING

To reduce the risk of fire or explosion and serious bodily injury, the turbine air (electrostatics) must be off before flushing.

1.Follow the Pressure Relief Procedure Warning on page 9.

2.Disconnect and plug the fluid line.

3.Connect the solvent supply to the gun.

4.Flush the gun with solvent until it is clean.

5.Follow the Pressure Relief Procedure Warning, then disconnect the solvent supply.

6.Reconnect the fluid supply line.

8. Actuate the gun until it is clear of solvent.
