3. Move the choke lever to the HALF CHOKE
POSITION, and pull the recoil handle (Figure 4)
two (2) times.
• If the engine STILL FAILS TO START, repeat
Steps 1-3.
4. Move the choke lever to the RUN POSITION by
sliding it to the right (away from the valve cover
and under the arrow).
5. Allow the engine to warm up for two (2) minutes
before using the equipment.

STOPPING THE ENGINE

1. Remove the load on the engine, and let it run for
30 seconds.
2. Turn off the engine by moving the RUN/STOP
SWITCH to the STOP position.
3. Close the fuel shut-off valve, if so equipped.

LOW PRESSURE SHUTDOWN SYSTEM

The engine is equipped with a low oil pressure sensor
that shuts down the engine should the oil pressure
drop below 8 psi. If the engine stops by itself, check
the engine oil and gasoline levels before restarting.

INITIAL STARTUP

A delay built in the low oil pressure sensor allows oil
pressure to build during starting. The delay allows
the engine to run for about 10 seconds before sensing
oil pressure.

SENSING LOW PRESSURE

If the system senses low oil pressure during opera-
tion, the engine shuts down. If the unit is equipped,
the low oil light comes ON as the unit shuts down.
However, once the engine stops rotating, this light
will go OFF .

RESTARTING THE ENGINE

If attempting to restart the engine within five (5) sec-
onds after it shuts down, the engine may NOT start.
The system needs 5 to 10 seconds to reset.
If an attempt has been made to restart the
engine after a shutdown, and the low oil pres-
sure has not corrected, the engine will run for
about 10 seconds before stopping.
GENERAL MAINTENANCE
RECOMMENDATIONS
The owner/operator is responsible for making sure
that all periodic maintenance tasks are completed on
a timely basis; that all discrepancies are corrected;
and that the equipment is kept clean and properly
stored. Never operate a damaged or defective engine.

Disconnect the spark plug wire from the spark
plug, and place the wire where it cannot come
in contact with the spark plug before working
on this engine.

CHECKING THE OIL LEVEL

See the BEFORE STARTING THE ENGINE section
on page 3 for information on checking the oil level.
The oil level should be checked before each use, or
at least every eight (8) hours of operation. Keep the
oil level maintained.

CHANGING THE OIL AND OIL FILTER

The engine may be equipped with an oil filter. Change
the oil and filter after the first eight (8) hours of
operation. Change the oil and oil filter (if so equipped)
every 100 hours thereafter. If using this engine
under dirty or dusty conditions, or in extremely hot
weather, change the oil more often.
Use the following instructions to change the oil while
the engine is still warm:
1. Clean the area around the oil drain plug, remove
the plug and drain the oil completely into a suit-
able container (Figure 5).
Placing the engine on a flat surface will allow
complete drainage. Tipping the engine towards
the drain plug will not allow complete drain-
age.
