Note: We supply the engine owner’s manual
with generator. Refer to that manual for ques-
tions concerning engine operation.
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 electrical
circuits, the chance of an electri-
cal fire exists.
DANGER: Use only in well-
vented areas. Make sure area
has plenty of free-moving, fresh,
outside air. Never run generator
in an enclosed or confined area.
Never run generator inside oc-
cupied building. Engine exhaust
contains poisonous carbon
monoxide gas. Overexposure will
cause loss of consciousness and
will lead to death.
