Grounding
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.
Pump: use ground wire and clamp (Graco P/N 222011,
not supplied), as shown in F
1. Connect the ground wire (Y) to the ground screw (Z)
located on the bottom of the air motor.
2. Connect the other end of the ground wire (Y) to a
true earth ground.

Air and fluid hoses: use only electrically conductive
hoses.
Air compressor: follow manufacturer's
recommendations.
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
surface, 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/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.
