Step 2: Oil and Fuel
Fuel must meet these requirements:
• Clean, fresh, unleaded fuel with a minimum of
87 octane/87 AKI (91 RON).
• 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 1524 m (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. Move generator outdoors to a flat, level surface.
2. Clean area around oil fill and remove oil fill cap/dipstick.
3. Slowly pour engine oil into oil fill opening to the full
mark on dipstick.

NOTICE Pause to permit oil to settle. Wipe dipstick clean
each time oil level is checked. DO NOT overfill.
4. Replace and fully tighten oil fill cap/dipstick.
5. Slowly remove fuel cap to relieve pressure in tank.
6. Slowly add unleaded fuel to fuel tank. Be careful not
to fill above lip. This allows adequate space for fuel
expansion.
7. Install fuel cap and let any spilled fuel evaporate
before starting engine.
High Altitude
At altitudes over 1524 m (5,000 ft.), a minimum 85 octane/85
AKI (89 RON) 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
762 m (2,500 ft.) 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 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. Push choke lever to CHOKE (
4. Set engine switch to ON (I) position.
5. Grasp recoil handle and pull slowly until slight
resistance is felt. Then pull rapidly to start engine.
6. Slowly move choke lever to RUN (
falters, move choke lever to half choke position until
engine runs smoothly, and then to RUN (
