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 screw (Z) and lockwasher on the
motor to attach ground wire 244524 (Y). Tighten the
screw securely. Connect the other end of the ground
wire to a true earth ground. See F

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 29 megohms, replace hose immedi-
ately.
Air compressor: follow manufacturer's recommenda-
tions.
Hydraulic power supply: follow manufacturer's recom-
mendations.
Surge tank: use a ground wire and clamp.
Spray gun: ground through a connection to a properly
grounded fluid hose and pump.
Fluid supply container: follow local code.

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.
