Operation
Step 2: Oil and Fuel
The generator engine is shipped from the factory filled with
10W30 oil . This allows for generator operation in a wide
range of temperature and climate conditions . For checking/
adding or changing oil see Maintenance.
Fuel must meet these requirements:
• Clean, fresh, unleaded fuel with a minimum of 87
octane .
• Gasoline with an ethanol content up to 10% is
acceptable .
E10 E15
NOTICE Do not mix oil in fuel or modify engine to run on
alternate fuels . Use of unapproved fuels could damage
engine and will not be covered under warranty .
See High Altitude for 5,000 ft . and above .
WARNING! Fuel and its vapors are extremely
flammable which could cause burns or fire
resulting in death or serious injury .
• Do not refuel during operation .
• Do not smoke during refueling .
• Turn engine off and let it cool at least 2 minutes before
removing fuel cap .
• Fill fuel tank outdoors . Keep fuel away from sparks, open
flames, pilot lights, heat, and other ignition sources .
Check fuel lines, tank, cap and fittings frequently for
cracks or leaks . Replace if necessary .
1 . Slowly remove fuel cap to relieve pressure in tank .
2 . Slowly add unleaded fuel to fuel tank . Be careful not
to fill above bottom lip . This allows adequate space
for fuel expansion .
3 . Install fuel cap and let any spilled fuel evaporate
before starting engine .

High Altitude
At altitudes over 5,000 ft . (1524 m), a minimum
85 octane fuel is acceptable . To remain emissions
compliant, high altitude adjustment is required . Operation
without this adjustment will cause decreased performance,
increased fuel consumption, and increased emissions .
See an authorized Briggs & Stratton dealer for high
altitude adjustment information . Operation of the engine at
altitudes below 2,500 ft . (762 m) with the high altitutde
kilt is not recommended .
Transporting
When transporting equipment with a vehicle or trailer, turn
fuel shutoff valve to off (0) position . Do not tip engine or
equipment at an angle which causes fuel to spill .
Step 3: Generator Start Up
Disconnect all electrical loads from the generator . Use the
following start instructions:
1 . Make sure unit is outdoors on a level surface .
NOTICE Failure to operate the unit on a level surface may
cause the unit to shut down .
2 . Turn the fuel valve to the on (I) position .

NOTICE If battery is discharged, use manual starting
instructions or charge battery with a battery charger
designed specifically for AGM batteries and follow all
charger instructions .
