Check Oil Level
See Figure: 3
Before adding or checking the oil
• Make sure the engine is level.
• Clean the oil fill area of any debris.
1. Remove the dipstick (A, Figure 3) and wipe with a clean
cloth.
2. Install and tighten the dipstick (A, Figure 3).
3. Remove the dipstick and check the oil level. Correct oil level
is at the top of the full indicator (B, Figure 3) on the dipstick.
4. If oil level is low, slowly add oil into the engine oil fill (C,
Figure 3). Do not overfill. After adding oil, wait one minute
and then recheck the oil level.
Note: Do not add oil at the quick oil drain , if equipped. For
location, see Features and Controls.
5. Reinstall and tighten the dipstick (A, Figure 3).
Oil Pressure
If the oil pressure is too low, a pressure switch (if equipped) will
either stop the engine or activate a warning device on the
equipment. If this occurs, stop the engine and check the oil level
with the dipstick.
If the oil level is below the ADD mark, add oil until it reaches
the FULL mark. Start the engine and check for proper pressure
before continuing to operate.
If the oil level is between the ADD and FULL marks, do not
start the engine. Contact an authorized dealer to have the oil
pressure problem corrected.
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.
Adding Fuel
WARNING
Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or death.
When Adding Fuel
• Turn engine off and let engine cool at least 3 minutes
before removing the fuel cap.
• Fill fuel tank outdoors or in well-ventilated area.
• Do not overfill fuel tank. To allow for expansion of the fuel,
do not fill above the bottom of the fuel tank neck.
• 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.
• If fuel spills, wait until it evaporates before starting engine.
1. Clean the fuel cap area of dirt and debris. Remove the fuel
cap (A, Figure 4).
2. Fill the fuel tank with fuel. To allow for expansion of the fuel,
do not fill above the bottom of the fuel tank neck (B).
3. Reinstall the fuel cap.
Starting the Engine
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Starting Engine
• Ensure that spark plug, muffler, fuel cap, and air cleaner
(if equipped) are in place and secured.
• Do not crank engine with spark plug removed.
• If engine floods, set choke (if equipped) to OPEN / RUN
position, move throttle (if equipped) to FAST position and
crank until engine starts.
