Checking/Adding Oil
Before adding or checking the oil
• Place engine level.
• Clean the oil fill area of any debris.
1. Remove the dipstick (
A
, Figure 5) and wipe with a
clean cloth.
2. Insert and tighten the dipstick.
3. Remove the dipstick and check the oil level. It should
be at the FULL mark (
B
) on the dipstick.
4. If low, add oil slowly into the engine oil fill (
C
).
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).
5. Replace and tighten the dipstick.
Oil Pressure
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.
CAUTION:
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. See the
Storage
section. 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 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,
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. Remove the fuel cap (
A
, Figure 6).
2. Clean the fuel cap area of dirt and debris.
3. Fill the fuel tank (
B
) with fuel. To allow for expansion
of the fuel, do not fill above the bottom of the fuel tank
neck (
C
).
4. Reinstall the fuel cap.
