Check Electrical Grounding

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 red-colored grounded air hose (R) is
connected and the hose ground wire is connected to
a true earth ground.

5.

Using an ohmmeter (AA), measure the resistance
between the gun handle (BB) and a true earth
ground (CC). The resistance should not exceed 100
ohms. See F

IG

. 13..

6.

If the resistance is greater than 100 ohms, 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.
