1. Completely turn off the air and fluid supplies to the gun.

2. Have a qualified electrician check the electrical grounding

continuity of the spray gun and air hose.

a. With the electrically conductive air hose con-

Use an applied voltage of 500 minimum

1000 volts maximum.

b. If the resistance is greater than 2 megohms*,

check the tightness of the ground connections, and be sure the air supply hose ground wire is connected to a true earth ground. If the resistance is still greater than 2 megohms*, replace the
