If the engine will not crank and the battery pack display lights
are flashing, then the battery pack temperature is too hot
or current draw is too high. All four battery display lights (H,
Figure 10) will flash a warning for 10 seconds. The battery
pack does not have a fuse, but will automatically reset after
10 seconds. If battery pack temperature is too hot (over
140 F, 60 C), remove the battery and allow it to cool. To
avoid excess current draw on lawnmowers, keep the mower
housing clean of grass build-up and debris.

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.
