Operation
Step 2: Oil and Fuel
Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service SF or
higher. Do not use special additives.
Outdoor temperatures determine the proper oil viscosity for
the engine. Use the chart to select the best viscosity for the
outdoor temperature range expected.
* Below 4°C (40°F) the use of SAE 30 will result in hard starting.
** Above 27°C (80°F) the use of 10W30 may cause increased oil
consumption. Check oil level more frequently.
Checking/Adding Engine Oil
Oil level should be checked prior to each use or at least
every 8 hours of operation. Keep oil level maintained.
1. Place generator on a level surface.
2. Loosen the two maintenance cover screws and
remove the side maintenance cover.
3. Clean area around oil fill and remove yellow oil fill cap.
4. Verify oil is at the point of overflowing at the oil fill
opening.

5. If needed, using oil funnel, slowly pour recommended
engine oil into oil fill opening to the point of overflowing.
NOTICE DO NOT attempt to crank or start engine before
it has been properly serviced with recommended oil. This
could result in an engine failure.
6. Replace oil fill cap and fully tighten.
7. Replace the maintenance cover and hand tighten the
two maintenance cover screws.
Add 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.
E15
E10
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. Clean area around fuel fill cap, remove cap.
2. Slowly add unleaded fuel to red fuel level indicator in
fuel tank. Be careful not to fill above the indicator. This
allows adequate space for fuel expansion.
