HANDLE
3. Move the choke lever to the HALF CHOKE
POSITION, and pull the recoil handle (Figure 5)
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

SWITCH (Figure 2) to the STOP position.
3. Close the fuel shut-off valve, if so equipped.
low oil pRessuRe sysTeM
Some engine applications may be equipped with a low
oil pressure switch. The switch is a normally closed
type, but is held open by engine oil pressure during
cranking and running. Should engine oil pressure
drop below approximately 10 psi for any reason, the
switch contacts will close. With the switch contacts
closed, the following will occur:
• A low oil pressure indicator will turn on and glow
as power is available for its operation.
• If so equipped, the closure of the switch contacts
will connect the primary ignition circuit to ground.
Ignition will terminate, and the engine will shut
down.
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.
