WARNING
FIRE, EXPLOSION, AND
ELECTRIC SHOCK HAZARD
Megohmmeter P/N 241079
2)is not approved for use in a hazard- ous area. To reduce the risk of sparking, do not use the megohmmeter to check electrical grounding unless:
DThe gun has been removed from the
hazardous area;
DOr 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 con- tainers or fumes from spraying).
Failure to follow this warning could cause fire, explosion, 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
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 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).
a.If using a black or grey air hose, use a me- gohmmeter (AA) to measure the resistance. Use an applied voltage of 500 minimum to 1000 volts maximum. The resistance should not exceed 2 megohms.
b.If using a red turbine air hose, use an ohmme- ter to measure the resistance. Resistance should not exceed 100 ohms.
6.If the resistance is greater than the maximum reading specified above for your hose, 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.
