7. Move the choke lever to the
OFF POSITION
by
pushing it in or move choke control to
RUN
position.
Allow engine to warm up for two minutes..
NOTE:
for cold weather starting: make sure the proper engine
oil is being used (see page 3).
STOPPING THE ENGINE
1. Remove load from engine.
2. Move throttle to
SLOW
position.
3. While still running, allow engine to cool for two minutes.
4. Turn key to
OFF
position.
5. Close fuel shut-off valve (if equipped).
LOW PRESSURE SHUTDOWN SYSTEM
(OPTIONAL)
The engine is equipped with a low oil pressure sensor that
shuts down the engine automatically when the oil pressure
drops below 8 psi. If the engine shuts down by itself and the
fuel tank has enough gasoline, check the engine oil level.
INITIAL STARTUP
A delay built in the shutdown system 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 operation, the
engine shuts down. The engine will not continue to run until 8
psi of oil pressure is reached.
RESTARTING THE ENGINE
If you try to restart the engine within (five) 5 seconds after it
shuts down, the engine may NOT start. The system needs 10
seconds to reset.
NOTE:
If you restart engine after a shutdown and have not
corrected the low oil pressure, the engine will run for
about 10 seconds as described above, and then it will stop.
