WARNING
Fast retraction of the starter cord (kickback) will pull your hand and arm to the
engine faster than you can let go. Broken bones, fractures, bruises or sprains
could result.
• To prevent kickback when you start the engine, pull the starter cord slowly until
resistance is felt and then pull quickly.
• Before you start the engine, disconnect or remove all external equipment and
engine loads.
• Make sure that direct-coupled equipment components, such as, but not limited
to, blades, impellers, pulleys, and sprockets, are correctly attached.
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.
NOTE: Your equipment could have remote controls. Refer to the equipment manual for
the location and operation of remote controls.
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 of systems.
• Electronic Fuel Injection (EFI) System: An EFI system does not have a
choke or a primer.
• Electronic Fuel Management System: An Electronic Fuel Management
system has an Electronic Control Unit that monitors engine and temperature
conditions. It does not have a manual choke or a primer.
• Choke System: This type of system has a choke to be used in cool
temperatures. Some models have a separate choke control, but some have a
combination choke and throttle choke. This type does not have a primer.
Electronic Fuel Injection (EFI) 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. Turn the electric start switch (D, Figure 8) 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
vanguardpower.com or call 1-800-999-9333.
Electronic Fuel Management 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 9), if installed, to the OPEN position.
4. Move the throttle control (B, Figure 9), if installed, to the FAST position. Operate the
engine in the FAST position

5. Turn the electric start switch (D, Figure 9) to the ON or START position
To extend the life of the starter, use short start cycles (five seconds maximum). Wait
one minute between start cycles.
NOTE: If the engine will not start, contact your local dealer or go to
vanguardpower.com or call 1-800-999-9333 (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 10), if installed, to the OPEN position.
4. Move the throttle control (B, Figure 10), if installed, to the FAST position. Operate
the engine in the FAST position.
5. Move the choke control (C, Figure 10), 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. Turn the key switch (D, Figure 10) to the ON or START position.
7. If the engine starts but will not continue to operate, move the choke control (C,
Figure 10) 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.
8. As the engine warms, move the choke control (C, Figure 10) 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. With the throttle control in the SLOW position, turn the electric start switch (D,
Figure 11) to the OFF position.
2. Remove the key and keep it in a safe location out of reach of children.
3. After the engine stops, move the fuel shut-off (A, Figure 11), if installed, to the
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.
