 Disengage the driven unit,or if equipped,put the transmission in neutral.
 Position the fuel shut-off,electrical switch or mechanism control to the RUN position.
Caution: To prevent damage to the starter, do not engage the starting motor more than 30
seconds. Wait 2 minutes between each attempt to start (electrical starting motors only).
 If the engine does not start after thereattempts,check the fuel supply system. Absence of blue or
white exhaust smokeduring cranking indicates no fuel is being delivered.
 Move the throttle position to idle as the engine starts.
 Engine oil pressure must be indicated on the gauge within 15 seconds after starting.
 When starting a cold engine,increase the engine speed (RPM) slowly to make sure adequate
lubrication is available to the bearings.
Caution: Do not idle the engine for excessively long periods. Long periods of idling (more than
10 minutes) can damage an engine because combustion chamber temperatures drop so low the
fuel will not burn completely. This will cause carbon to clog the injector spray holes and piston
rings, and can cause the valves to stick. If the engine coolant temperature becomes too low
(60 °C [140 °F]), raw fuel will wash the lubricating oil off the cylinder walls and dilute the
crankcase oil; therefore, all moving parts of the engine will not receive the correct amount of
lubrication.
 Idle the engine 3 to 5 minutes before operating with a load.
Caution: When using jumper cables to start the engine, make sure to connect the cables in
parallel: positive (+) to positive (+) and negative (-) to negative (-). When using an external
electrical source to start the engine, turn the disconnect switch to the “OFF” position. Remove
the key before attaching the jumper cables to prevent unintentional starter engagement.
