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 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

voltage of 500 minimum to 1000 volts maximum.

The resistance should not exceed 1 megohm. See

FIG. 4.

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.

WARN ING

Fire, Explosion, and Electric Shock Hazard

Megohmmeter Part No. 241079 (AA-see

FIG. 4.) 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

hazardous 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.
