Grounding
The following are minimum grounding requirements for
a basic electrostatic system. Your system may include
other equipment or objects which must be grounded.
Check your local electrical code for detailed grounding
instructions. Your system must be connected to a true
earth ground.

All air and fluid lines must be properly grounded.
Use only grounded hoses with a maximum of 100
feet (30.5 m) combined hose length to ensure
grounding continuity.

All persons entering the spray area: shoes must
have conductive soles, such as leather, or personal
grounding straps must be worn. Do not wear shoes
with non-conductive soles such as rubber or plastic.
If gloves are necessary, wear the conductive gloves
that are supplied with the gun. If non-Graco gloves
are worn, cut off fingers or palm area of gloves to
ensure your hand contacts the grounded gun han-
dle.

Fire, Explosion, and Electric Shock Hazard
When operating the electrostatic gun, any ungrounded
objects in the spray area (people, containers, tools,
etc.) can become electrically charged. Improper
grounding can result in static sparking, which can
cause a fire, explosion, or electric shock. Follow the
grounding instructions below.
