5. Add fuel to the tank:
• Make sure the mower is outside, where fumes can
safely dissipate.
• Remove the fuel fill cap (C, Figure 4).
• Fill the tank with fuel. See Fuel Recommendations .
To allow for expansion of the fuel, do not fill above the
bottom of the filler neck (D).
• Reinstall the fuel fill cap.
6. Clean the exterior surfaces of the cutting deck and engine
of any accumulation of spilled fuel, dirt, grass, oil, etc. Keep
the engine air intake screen and cooling fins clear at all
times.
7. Charge the battery. See Charging the Battery .

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, SG, SH, SJ 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.
A. SAE 30 - Below 40°F (4°C) the use of SAE 30 will result in hard
starting.
B. 10W-30 - Above 80°F (27°C) the use of 10W-30 may cause
increased oil consumption. Check oil level more frequently.
C. Synthetic 5W-30
D. 5W-30

Fuel Recommendations

Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane / 87 AKI (91 RON). For high altitude
use, see below.
• Gasoline with up to 10% ethanol (gasohol) is acceptable.
NOTICE Do not use unapproved gasolines, such as E15
and E85. Do not mix oil in gasoline or modify the engine to
run on alternate fuels. Use of unapproved fuels will cause
damage to engine components, which will not be covered
under warranty.
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. See Storage. All fuel is not the same. If
starting or performance problems occur, change fuel providers
or change brands. This engine is certified to operate on gasoline.
The emissions control system for this engine is EM (Engine
Modifications).

High Altitude

At altitudes over 5,000 feet (1524 meters), a minimum 85
octane/85 AKI (89 RON) gasoline is acceptable.
For carbureted engines, high altitude adjustment is required to
maintain performance. Operation without this adjustment will
cause decreased performance, increased fuel consumption,
and increased emissions. Contact a Briggs & Stratton Authorized
Service Dealer for high altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet (762
meters) with the high altitude adjustment is not recommended.
For Electronic Fuel Injection (EFI) engines, no high altitude
adjustment is necessary.
