WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result
in burns or death.
When you start the engine
•
Make sure that the spark plug, muffler, fuel cap and air cleaner (if equipped)
are correctly installed.
•
Do not crank the engine with the spark plug removed.
•
If the engine is flooded, set the choke (if equipped) to the OPEN or RUN
position. Move the throttle (if equipped) to the FAST position and crank until the
engine starts.
•
If there is natural or LP gas leakage in the area, do not start the engine.
•
Because vapors are flammable, do not use pressurized starter fluids.
WARNING
POISONOUS GAS HAZARD. Engine exhaust contains carbon monoxide, a
poisonous gas that could kill you in minutes. Although you do not smell exhaust
fumes, you could still be exposed to dangerous carbon monoxide gas. If you feel
sick, dizzy, or weak while you use this product, get to fresh air RIGHT AWAY.
See a doctor. You may have carbon monoxide poisoning.
•
Carbon monoxide gas can collect in occupied spaces. To reduce the risk of
carbon monoxide gas, ONLY operate this product outdoors and far away from
windows, doors and vents.
•
Install battery-operated carbon monoxide alarms or plug-in carbon monoxide
alarms with battery back-up as specified by the manufacturer's instructions.
Smoke alarms cannot sense carbon monoxide gas.
•
DO NOT operate this product in homes, garages, basements, crawlspaces,
sheds, or other closed spaces, even if you use fans or open doors and
windows for ventilation. After the operation of this product, carbon monoxide
can quickly collect in these spaces and stay for hours.
•
ALWAYS put this product downwind and point the engine exhaust away from
occupied spaces.
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.
Types of Start Systems
Before you start the engine, you must know the type of start system on your engine.
Your engine has one of these types.
•
Electronic Fuel Injection (EFI) System: This system does not have a choke
or a primer.
Choke System: This type of system has a choke to use in cool temperatures.
•
Some models have a choke control, but other models have a combination
choke and throttle choke. It does not have a primer.
NOTE: Your equipment can have remote controls. Refer to the equipment manual for
location and operation of remote controls.
Electronic Fuel Injection (EFI) System
1.
Check the engine oil. See the Check Oil Level section.
2.
Make sure that equipment drive controls, if installed, are disengaged.
3.
Move the fuel shut-off (A, Figure 7), if installed, to the OPEN position.
4.
Move the throttle control (B, Figure 7), if installed, to the FAST position. Operate the
engine in the FAST position.
NOTE: For models with Electronic Throttle Control, the throttle control can be in any
position when you start the engine.
5.
Turn the electric start switch (D, Figure 7) to the ON or START position.
NOTICE To extend the life of the starter, use short start cycles (five seconds maximum).
Wait one minute between start cycles.
If the engine does not start after 3 or 4 times, contact your local dealer or go to
BRIGGSandSTRATTON.COM or call 1-800-444-7774 (in USA).
Choke System
1.
Check the engine oil. See the Check Oil Level section.
2.
Make sure that the equipment drive controls, if installed, are disengaged.
3.
Move the fuel shut-off (A, Figure 8), if installed, to the OPEN position.
4.
Move the throttle control (B, Figure 8), if installed, to the FAST position. Operate the
engine in the FAST position.
5.
Move the choke control (C, Figure 8), or the combination choke and throttle (B,C), if
installed, to the CLOSED position.
NOTE: To start the engine with a dry fuel system, additional cranking time in the choke
position will be required. This will give the fuel pump time to prime the fuel system.
6.
Turn the key switch (D, Figure 8), if installed, to the ON or START position.
7.
If the engine starts but will not continue to operate, move the choke control (C,
Figure 8) to the OPEN position to start the engine.
8.
As the engine warms, move the choke control (C, Figure 8) to the OPEN position.
NOTE: If the engine will not start, contact your local dealer or go to
vanguardpower.com or call 1-800-999-9333 (in USA).
Stop the Engine
WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
•
Do not choke the carburetor (if equipped) to stop the engine.
1.
Disengage equipment controls. See the equipment manual for location and
operation of remote controls.
2.
Move the throttle control (B, Figure 9), if installed, to the SLOW position.
3.
Turn the key switch (D, Figure 9) to the OFF or STOP position. Remove the key,
and keep it in a safe location out of reach of children

Maintenance
Maintenance Information
WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
During maintenance if it is necessary to tilt the unit, make sure that the fuel tank, if
mounted on the engine, is empty and that the spark plug side is up. If the fuel tank is not
empty, leakage can occur and could result in a fire or an explosion. If the engine is tilted
in a different direction, it will not easily start because of oil or fuel contamination of the air
filter or the spark plug.
WARNING
Accidental engine spark can cause an electric shock, fire or explosion and could
result in entanglement, traumatic amputation or laceration.
Before you make adjustments or repairs:
•
Disconnect all spark plug wires and keep them away from the spark plugs.
•
Disconnect the battery wire from the negative battery terminal (only engines with
electric start).
•
Use only the correct tools.
When you check for spark:
•
Use an approved spark plug tester.
•
Do not check for spark with the spark plug removed.
WARNING
All the components used to assemble this engine must stay in the initial position
for correct operation. Damage or injury can occur if you use incorrect parts or you
do not replace all parts on the engine.
•
Replacement parts must be of the same design and installed in the same
position as initial parts.
•
If installed, do not change the governor spring, links, or other parts to increase
the engine speed.
See a Briggs & Stratton Authorized Service Dealer for all maintenance and servicing of
the engine and engine parts.
Emissions Control Service
