1.11 Indoor Operation
If the generator must be operated indoors, adequate
ventilation or exhaust hoses must be provided. When
venting exhaust fumes, make sure the exhaust piping is
large enough to prevent excessive back pressure to the
engine. Back pressure reduces engine efficiency and
may cause the engine to overheat.
Exhaust gas from the engine contains poisonous
carbon monoxide gas; exposure to carbon monox-
ide can cause loss of consciousness and may lead
to death. Never run generator indoors or in an
enclosed area unless adequate ventilation, through
such items as exhaust fans or hoses, is provided.
When operated indoors, steps to prevent fire and explo-
sion such as providing a good earthen ground, removing
all flammable materials near generator, and using only
electric cables in good condition, must be observed. See
Section
Operating Safety.

DANGER
1.12 Use of Extension Cords
When a long extension cord is used to connect an
appliance or tool to the generator, a voltage loss occurs—
the longer the cord, the greater the voltage loss. This
results in less voltage being supplied to the appliance or
tool and increases the amount of current draw or reduces
performance. A heavier cord with a larger wire size will
reduce the voltage loss.
CAUTION: Operating equipment at low voltage can
cause it to overheat.
Use the chart as a guide for selecting proper cable size.
Use only extension cords rated for outdoor use and
equipped with a third-wire ground.
