WARNING
Rotating parts can entangle hands, feet, hair, clothing, or accessories and result
in traumatic amputation or laceration.
•
Operate equipment with the guards correctly installed.
•
Keep hands and feet away from rotating parts.
•
Remove jewelry and make sure that long hair is away from all rotating parts.
•
Do not wear loose clothes or items that could become caught.
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.
NOTE: Some engines and equipment have remote controls. Refer to the equipment
manual for the location and operation of remote controls.
1.
Check the engine oil. See the Check Oil Level section.
2.
Make sure that the equipment drive controls, if installed, are disengaged.
3.
Turn the stop switch (A, Figure 7), if installed, to the ON position.
4.
Move the throttle control (B, Figure 7), if installed, to the FAST position. Operate the
engine in the FAST position.
5.
Move the choke control (C, Figure 7) to the CLOSED position.
NOTE: Choke is usually not necessary when you start a warm engine.
6.
Move the fuel shut-off (D, Figure 7), if installed, to the OPEN position.
7.
Tightly hold the starter cord handle (E, Figure 7). Pull the starter cord handle slowly
until resistance is felt, then pull quickly.
8.
As the engine warms, move the fuel shut-off (D, Figure 7), if installed, to the
CLOSED position.
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 (A, Figure 8) to the STOP position.
2.
Throttle Control, if installed: Move the throttle control (B, Figure 8) to the SLOW
position and then to the STOP position.
3.
After the engine stops, move the fuel shut-off (D, Figure 8), if installed, to the
CLOSED position.
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
Replacement parts must be of the same design and installed in the same position as the
original parts. Other parts could result in damage or an injury.
NOTICE
All the components used to build this engine must remain in place for correct operation.
See a Briggs & Stratton Authorized Service Dealer for all maintenance and servicing of
the engine and engine parts.

torque specifications, refer to the Specifications section.
Servicing the Exhaust System
WARNING
During operation, the engine and muffler become hot. If you touch a hot engine,
thermal burns can occur.
Combustible materials, such as leaves, grass and brush, can catch fire.
•
Before you touch the engine or muffler, stop the engine and wait two (2)
minutes. Make sure that the engine and muffler are safe to touch.
•
Remove debris from the muffler and engine.
