Daily Care and Cleaning

Manual background 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. 12.

DHang the gun with its nozzle pointing down when it is not being used.

1.Clean the fluid and air line filters daily.

2.Clean the outside of the gun daily with a soft cloth dampened in a non-flammable cleaning fluid.

3.Clean the air cap and fluid nozzle daily, minimum, as instructed on page 21. Some applications require more frequent cleaning. Replace the fluid nozzle and air cap if they are damaged. See page 30.

4.Check the electrode wire. Straighten it if it is bent, and replace it if it is broken or damaged. See page 32.

5.Check for any 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 21.
