OPERATION
CHECK THE OiL (BEFORE STARTING ENGINE)
NOTE: The engine was shipped from the factory filled with
oil. Check the Jevel of the oil. Add oJJas needed.
1. Make sure the unit is level. Use a high quality detergent oil
classified "For Service SG, SH, SJ, SL, or higher".
2. Remove the oil fill cap/dipstick (A, Figure 7) and wipe with a
clean cloth.
3. Insert the oil fill cap/dipstick and turn clockwise to tighten.
4. Remove the oil fill cap/dipstick and check the oil.
NOTE: Do not check the level of the oJJwhile the engine
runs.
5. If necessary, add oil until the oil reaches the FULL mark on the
oil fill cap/dipstick. Do not add too much oil.
6. Tighten the oil fill cap/dipstick securely each time you check
the oil bevel.
NOTE: Synthetic 5W30 motor oil is acceptable for alt
temperatures. DO NOT mix oil with gasoline. See Chart for
oiJ recommendations.

FUEL RECOMMENDATIONS
Fuel must meet these requirements:
. Clean, fresh, unleaded gasoline.
. A minimum of 87 octane/87 AKI (91 RON). High altitude use,
see below.
Gasoline with up to 10% ethanol (gasohot) or up to 15% MTBE
(methyl tertiary butyl ether) is acceptable.
NOTICE: Do not use unapproved gasolines, such as E85. Do
not mix oil in gasoline or modify the engine to run on
alternate fuels. This will damage the engine components
and void the engine warranty.
To protect the fuel system from gum formation, mix a fuel stabilizer
into the fuel. 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. To remain
emissions compliant, high altitude adjustment is required.
Operation without this adjustment will cause decreased
performance, increased fuel consumption, and increased
emissions. See a Briggs & Stratton Authorized Dealer for high
altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet (762 meters)
with the high altitude kit is not recommended.
