OPERATION
GENERAL INFORMATION
This generator is not large enough to power
your entire home. Do not connect generator
to any existing electrical circuits. Plug items
directly into generator receptacles. Do not
exceed amperage rating of receptacles. Only
use grounded cords.
DANGER: Use only in well-
vented areas. Make sure area has
plenty of free-moving, fresh, out-
side air. Never run generator in
an enclosed or confined area.
Never run generator inside occu-
pied building. Engine exhaust
contains poisonous carbon mon-
oxide gas. Overexposure will
cause loss of consciousness and
will lead to death.
DANGER: Never connect gen-
erator to any existing electrical
circuits. The generator output will
back-feed into the utility power
line. This may electrocute a power
company line repair person. Also,
if generator is powering electri-
cal circuits, the chance of an elec-
trical fire exists.
Note: We supply the engine owner’s manual
with generator. Refer to that manual for
questions concerning engine operation.
USING RECEPTACLE
Note: Do not exceed amperage rating of
receptacles. Exceeding rating will trip re-
ceptacle circuit breaker.
Use receptacles properly. Improper use could
damage generator. Use only grounded ex-
tension cords. Power only grounded or
double-insulated items. Do not overload
receptacles. All generators (except models
HWI3000 and MGH3000) have the follow-
ing receptacles (see Figure 15):
