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 equipment drive controls, if equipped, are disengaged.
3. Move the fuel shut-off (A, Figure 5), if equipped, to the OPEN position.
4. Move the throttle control (B, Figure 5), if equipped, to the FAST position. Operate
the engine in the FAST position.
NOTE:
For models with Electronic Throttle Control, the throttle control does not have to
be in a specified position.
5. Push the stop switch (D, Figure 5), if equipped, to the ON position.
6. Turn the electric start switch (E, Figure 5) 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.
Choke System
1. Check the engine oil. See
Check Oil Level
section.
2. Make sure that the equipment drive controls, if installed, are disengaged.
3. Move the fuel shut-off (A, Figure 6), if installed, to the OPEN position.
4. Move the throttle control (B, Figure 6), if installed, to the FAST position. Operate the
engine in the FAST position.
5. Move the choke control (C, Figure 6), or the combination choke and throttle (B,C) 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. Push the stop switch (D, Figure 6), if installed, to the ON position.
7. Turn the key switch (E, Figure 6) to the ON or START position.
8. If the engine starts but will not continue to operate, move the choke control (C,
Figure 6) to the OPEN position to start the engine.
NOTICE
To extend the life of the starter, use short start cycles (five seconds maximum).
Wait one minute between start cycles.
9. As the engine warms, move the choke control (C, Figure 6) to the OPEN position.
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.
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.
Stop Switch, if installed:
Move the stop switch (D, Figure 7) to the OFF position.
2.
Key Switch, if installed:
Set the throttle control to the SLOW position. Turn the
key switch (E, Figure 7) to the OFF position. Remove the key and keep it in a safe
location out of reach of children.

CLOSED position.
Maintenance
Maintenance Information
WARNING
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.
We recommend that you see a Briggs & Stratton Authorized Service Dealer for all
maintenance and servicing of the engine and engine parts.
NOTICE
All the components used to build this engine must remain in place for correct operation.
WARNING
Accidental engine spark can cause an electric shock or fire and could result in
entanglement, traumatic amputation or laceration.
Before you make adjustments or repairs:
•
Disconnect the spark plug wire and keep it away from the spark plug.
•
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.
Emissions Control Service
For maintenance, replacement, or repair of emissions control devices and
systems, contact a qualified off-road engine repair establishment or service
technician.
However, for "no charge" emissions control service, the work must be done
by a factory authorized dealer. Refer to the Emissions Control Statements.
