Grounding
Grounding Procedure for
Gas Engine
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.
To ground sprayer: Attach sprayer
grounding clamp to earth ground.
Air and fluid hoses: Use only electrically
conductive hoses with a maximum of 500ft.
(150 m) combined hose length to ensure
grounding continuity. Check electrical
resistance of hoses. If total resistance to
ground exceeds 29 megaohms, replace hose
immediately.
Spray gun: Ground through connection to a
properly grounded fluid hose and pump.
