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.
If this engine is equipped with a primer bulb, use
the following instructions.
1. Press the primer bulb three (3) times, waiting two (2)
seconds between each push (Figure 5).

you feel slight resistance, then PULL QUICKLY. Repeat
pulling the recoil handle three (3) times, if necessary.
3. If the engine FAILS TO START, repeat Steps 1 and 2.
4. 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 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. As the system shuts down, the low oil light
comes ON (see Figure 2, page 6 ). However, once the engine
stops rotating, this light will go OFF.
RESTARTING THE ENGINE
If you try to restart the engine within 5 seconds after it shuts
down, the engine may NOT start. The system needs 5 to 10
seconds to reset.
NOTE: If you do 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.
