To reduce the risk of an injury, follow the Pressure Relief Procedure on page 11 when you stop spraying, before cleaning or flushing the spray gun, and whenever you are instructed to relieve the pressure.

WARNING

FIRE, EXPLOSION, AND ELECTRIC

SHOCK HAZARD

To reduce the risk of fire, explosion, or electric shock, turn the ES ON-OFF lever OFF before flushing the gun.

CAUTION

Fluid left in gun air passages could result in a poor quality paint finish and may draw current and reduce the electrostatic effect. Fluid in the power supply cavity can reduce the alternator life.

DImmersing the gun in fluid is not recom- mended.

DDo not use any cleaning method which may allow solvent into the gun air passages. Point the gun down while cleaning to prevent fluid from running into the air passages. See Fig. 7.

DHang the gun with its nozzle pointing down when it is not being used, as shown in Fig. 6.

Clean all parts with a non-conductive, compatible solvent. Conductive solvents can cause the gun to malfunction.

1.Clean the fluid and air line filters daily.

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

3.Clean the air cap and fluid nozzle daily, minimum. See page 15. Some applications require more frequent cleaning. Replace the fluid nozzle and air cap if they are damaged. See page 22.

4.Check the electrode wire. Straighten it if it is bent, and replace it if it is broken or damaged. See page 23.

5.Check for fluid leakage from the gun and fluid hoses. Tighten fittings or replace equipment as needed.

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

7.Flush the gun before changing colors and whenev- er you are done operating the gun. See page 15.

NOTE: A Gun Washer Kit, P/N 236681, is available for use with a Graco Gun Washer. See Accessories.

8.Place the gun in its hanging bracket, with the nozzle pointing down as shown in Fig. 6, until it is used again.

Methylene chloride is not recommended as a flush- ing or cleaning solvent with this gun as it will damage nylon components.
