WARNING: For a grounding
point, do not use metal pipe be-
ing used to carry combustible
materials or gases.
Grounding generator helps prevent electric
shock from a ground fault condition. Locate
ground lug on end of generator housing (see
Figure 16). Attach a #10 stranded-copper
ground wire to ground lug. Drive grounding
point into ground. Grounding point can be a
stake, grounding rod, or pipe. Grounding
point should be copper or brass. Attach
ground wire to grounding point. You must
supply the ground wire and grounding point.
These do not come with generator. Follow
the National Electrical Code and all state
and local codes. Consult your power com-
pany or a licensed electrician.
WARNING: You must prop-
erly earth-ground generator be-
fore starting. This will help guard
against deadly electric shock.
Only use grounded plugs with
generator. Only use grounded ex-
tension cords. Only use three-
wire or double-insulated power
tools.
