5.
Remove the control link (H, Figure 13).
NOTE: At this time, the throttle control / TransportGuard
positions: STOP / OFF position and RUN position.
6.
Install the new ON / OFF TransportGuard
speed control label located on the trim panel (F).
Operation
WARNING
Fuel vapors are flammable and explosive. Fire or explosion could result in burns
or death.
If you smell gas
•
Do not start the engine.
•
Do not switch on electrical switches.
•
Do not use a phone in the vicinity.
•
Evacuate the area.
•
Contact the fire department.
When you operate the equipment
•
Do not tilt the engine or the equipment at an angle which causes fuel to spill.
When you move the location of the equipment
•
Make sure that the fuel tank is EMPTY or that the fuel shut-off valve, if installed,
is in the CLOSED position.
Check the Oil Level
Before you check or add oil
•
Make sure that the engine is level.
•
Clean the oil area of debris.
See the Specifications section for oil capacity.
•
NOTICE
This engine was shipped from Briggs & Stratton without oil. Equipment manufacturers or
dealers could have added oil to the engine. Before you start the engine for the first time,
make sure that the oil is at the correct level. Add oil as specified by the instructions in
this manual. If you start the engine without oil, damage will occur and the engine will not
be repaired under warranty.
1.
Remove the dipstick (A, Figure 15) and clean with a cloth
2.
Install the dipstick (A, Figure 15).
3.
Remove the dipstick and check the oil level. Make sure that the oil level is at the top
of the full indicator (B, Figure 15) on the dipstick.
4.
The engine has two oil fills (C, G, Figure 16). If the oil level is low, slowly add oil into
the engine oil fills (C, G). Do not add too much oil. After you add oil, wait one minute
and check the oil level again. Make sure that the oil level is correct.
5.
Install the dipstick (A, Figure 15).
Oil Recommendations
Oil Capacity: Refer to SECTION 9 - SPECIFICATIONS.
We recommend the use of Briggs & Stratton
performance. Other high-quality detergent oils are permitted if classified for service SF,
SG, SH, SJ or higher. Do not use special additives.
Use the chart to select the best viscosity for the outdoor temperature range expected.

Low Oil Protection System (if installed)
A low oil sensor is installed on some engines. If the oil is low, the sensor will show a
warning light or stop the engine. Stop the engine and do the steps that follow before you
start the engine.
•
Make sure that the engine is level.
•
Do an oil check. Refer to the Check Oil Level section.
•
If the oil level is low, add the correct amount of oil. Start the engine and make
sure that the warning light (if installed) does not come on.
•
If the oil level is not low, do not start the engine. Contact a Briggs & Stratton
Authorized Service Dealer to correct the oil problem.
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 (gasohol) is permitted.
NOTICE
Do not use unapproved gasoline, such as E15 and E85. Do not mix oil in gasoline or
change the engine to operate on alternate fuels. Use of unapproved fuels could result
in damage to engine components, which will not be repaired under the warranty.
To protect the fuel system from gum formation, and corrosion, mix an alcohol-free fuel
stabilizer and ethanol treatment into the fuel. Refer to the Storage section. All fuel is
not the same. If start or performance problems occur, change fuel providers or brands.
This engine is certified to operate on gasoline. The emissions control system for
carbureted engines is EM (Engine Modifications). The emissions control systems for
engines with electronic fuel injection are ECM (Engine Control Module), MFI (Multiport
Fuel Injection), TBI (Throttle Body Fuel Injection) and if equipped an O2S (Oxygen
Sensor).
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum 87 octane/87 AKI (91 RON)
gasoline is permitted.
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.
Add Fuel
WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
When you add fuel
•
Stop the engine. Before you remove the fuel cap, wait a minimum of two (2)
minutes to make sure that the engine is cool.
•
Fill the fuel tank outdoors or in an area that has good airflow.
•
Do not put too much fuel in the tank. 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.
•
Frequently examine the fuel lines, fuel tank, fuel cap, and connections for cracks
or leaks. Replace damaged parts.
•
If fuel spills, wait until it dries before you start the engine.
1.
Clean the fuel cap area of dirt and debris. Remove the fuel cap.
2.
Fill the fuel tank (A, Figure 17) with fuel. Because fuel will expand, do not fill above
the bottom of the fuel tank neck (B).
3.
Install the fuel cap.
