Grounding
The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit.
Pump: use a ground wire and clamp. See FIG. 1. Remove the green ground screw (Z) from the bottom of the air motor. Insert the screw through the loop on the end of the ground wire (Y) and reattach the screw to the air motor. Connect the ground clamp to a true earth ground. Order Part No. 244524, Ground Wire and Clamp.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code. Use only conductive metal pails, placed on a grounded surface. Do not place the pail on a nonconductive sur- face, such as paper or cardboard, which interrupts grounding continuity.
To maintain grounding continuity when flushing or relieving pressure: hold metal part of the spray gun firmly to the side of a grounded metal pail, then trigger the gun.

FIG. 1. Ground Wire
Air and fluid hoses: use only electrically conductive hoses with a maximum of 500 ft. (150 m) combined hose length to ensure grounding continuity. Check the electrical resistance of hoses. If total resistance to ground exceeds 25 megohms, replace hose immedi- ately.
Air compressor: follow manufacturer’s recommenda- tions.
Surge tank: use a ground wire and clamp.
Dispense valve: ground through a connection to a properly grounded fluid hose and pump.
Fluid supply container: follow local code.
