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.
Systems: Use the supplied ground wire and clamp
(237686).
Air and fluid hoses: Use only genuine Graco blast
hoses with a maximum of 150 ft (45 m) combined blast
hose length to ensure grounding continuity. Check the
electrical resistance of the blast hoses. If the total resis-
tance to ground exceeds 29 megaohms, replace the
blast hose immediately.
Air compressor: Follow the manufacturer's
recommendations.
