GROUND TESTING
Improper installation or alteration of grounding plug could results in risk of electric shock, fire or explosion that could cause serious injury or death.
The other function of the grounding plug is to protect the control board from static build up. If the plug is missing this could cause permanent damage
to the control board.
Every corded electric sprayer that comes into your shop for repair should be tested as described below, to make sure that it is properly grounded.
Pull the machine's plug out of the wall outlet and connect one lead from a DC continuity test light or a VOM to the (round) gro und terminal on the
plug.
NOTE:
If the ground terminal is broken off of the plug, install a new plug.
Touch the test light (or VOM) leads to several bare metal surfaces on the body of the machine. If the light (or meter) indicates continuity, the machine
is properly grounded. If the light (or meter) doesn't indicate continuity trace through the ground (green) wiring on the machine to determine where
the break is.
