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.
• 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 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 altitude kit 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 battery charger and 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.

3. Pull choke control out to close choke (
4. Turn and hold key in start switch to START position
until generator starts. DO NOT hold key in START
position for more than 5 seconds. Pause for at least
30 seconds between starting attempts.
Start Switch
NOTICE If battery is discharged, turn key in start switch
to RUN position, grasp recoil handle and pull slowly until
slight resistance is felt. Then pull rapidly one time only to
start engine.
5. Open choke gradually as engine warms up by pushing
in on choke handle.
NOTICE If engine starts but fails to run, see Low Oil
Shutdown in Features and Controls.
