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 can cause increased
oil consumption. Check oil level more frequently.
C 5W-30
D Synthetic 5W-30
E Vanguard

Synthetic 15W-50
*Below 40°F (4°C) the use of SAE 30 will result in hard starting.
**Above 80°F (27°C) the use of 10W-30 can cause increased oil consumption.
Check oil level more frequently.
1. Put the unit on a level surface as shown in Figure 4.
2. Stop the engine and remove the key.
3. Make sure that the oil fill area is clean.
4. Remove the dipstick (A, Figure 5). Remove the remaining
oil from the dipstick.
5. Install and tighten the dipstick.
6. Remove the dipstick again, and check the oil level. Make
sure that the oil level is at the top of the FULL mark
(B) on the dipstick.
7. If the oil level is FULL, install and tighten the dipstick.
8. If the oil level is LOW, add oil into the engine oil fill tube
(C). Do not overfill.
Note: Do not add oil at the quick oil drain (if equipped).
9. Wait one minute, and check the oil level again.
10. Replace and tighten the dipstick.
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 the correct oil
pressure before you continue to operate the machine.
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.
Add Fuel
Fuel must meet these requirements:
• Clean, unleaded gasoline.
• A minimum of 87 octane / 87 AKI (91 RON). See
High
Altitude Requirements .
• Gasoline with up to 10% ethanol (gasohol).
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. If start or performance problems occur,
change fuel providers or brands. This engine is certified to
operate on gasoline. The emissions control system for this
engine is EM (Engine Modifications).
High Altitude Requirements
• At altitudes over 5,000 feet (1,524 meters), a minimum 85
octane / 85 AKI (89 RON) gasoline is acceptable.
• For carbureted engines, high altitude adjustment is
required to remain emissions compliant. 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, high altitude
adjustment is not necessary.
WARNING
Fuel and its vapors are extremely flammable and explosive.
Always handle fuel with extreme care. Failure to Observe
these safety instructions can cause fire or explosion which
could result in severe burns or death.
• Turn the engine off and let the engine cool at least 3
minutes before you remove the fuel cap.
• Extinguish all cigarettes, cigars, pipes, and other
sources of ignition.
• 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 and avoid creating any source of ignition.
• Use only an approved fuel container.
1. Remove unwanted material from the fuel cap area.
2. Remove the fuel cap (A, Figure 6).
3. Fill the fuel tank (B) with fuel. DO NOT fill above the
bottom of the fuel tank neck (C).
4. Install the fuel cap.
Start the Engine
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Starting the 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.
