GENERATOR
FEATURES
OIL ALERT SYSTEM
The oil alert system protects the engine from
low oil damage. This system automatically
shuts down the engine and prevents engine
restarting if the oil level falls too low.
If this system shuts down the engine, the
engine will not start until you add oil. Add
oil to engine (see Engine Oil, page 6).
See engine owner’s manual for more
information.
BATTERY DISCHARGE LAMP
The battery discharge lamp (see Figure 2)
will light if battery charger is not operating
while engine is running. If this happens, the
battery will not charge and will eventually
run down. Have battery charging circuit
repaired by authorized service person.
VENTILATION
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.
This generator needs cooling air to run prop-
erly. Never block free-flowing, cooling air
to generator. Overheating will occur with-
out cooling air. This will damage the gen-
erator. Keep generator at least three feet
away from any object.
DUST, DIRT, RAIN,
AND SNOW
WARNING: Do not use gen-
erator outdoors in rain or snow.
Do not use generator near stand-
ing water or snow. Do not use if
generator is wet or damp. Oper-
ating generator in these condi-
tions increases the risk of elec-
trocution. Severe injury or death
can occur.
Do not use generator in extremely dusty or
dirty conditions. This will severely affect its
life. Keep generator clean. Do not allow
dust, dirt, rain, or snow to collect on it.
Protect generator from outdoor elements.
HIGH AND LOW
TEMPERATURE
OPERATION
Air temperature affects generator output.
Output drops 1% for each 10° temperature
rise above 60° F. Very low temperatures may
