Check Electrical Grounding

WARNING

Fire, Explosion, and Electric Shock Hazard

Megohmmeter Part No. 241079 (AA-see Fig. 3) is not approved for use in a hazard- ous area. To reduce the risk of sparking, do not use the megohmmeter to check electri- cal grounding unless:

• The gun has been removed from the haz- ardous area;

•Or all spraying devices in the hazardous area are turned off, ventilation fans in the hazardous area are operating, and there are no flammable vapors in the area (such as open solvent containers or fumes from spraying).

Failure to follow this warning could cause fire, explosion, and electric shock and result in serious injury and property damage.

1.Have a qualified electrician check the electrical grounding continuity of the spray gun and air hose.

2.Turn the ES ON/OFF valve OFF.

3.Turn off the air and fluid supply to the gun. The fluid hose must not have any fluid in it.

4.Make sure the grounded air hose (R) is connected and the hose ground wire is connected to a true earth ground.

5.Measure the resistance between the gun handle (BB) and a true earth ground (CC). Use an applied volt- age of 500 minimum to 1000 volts maximum. The resistance should not exceed 1 megohm. See Fig. 3.

6.If the resistance is greater than 1 megohm, check the tightness of the ground connections and be sure the air hose ground wire is connected to a true earth ground. If the resistance is still too high, replace the air hose.
