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 three attempts, check the fuel supply system. Absence of blue or
white exhaust smoke during cranking indicates no fuel is being delivered.
Move the throttle position to idle as soon 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 (60C
[140F]), 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.
