OPERATION 12.5 STARTING ENGINE 12.5.1 NORMAL STARTING PROCEDURES IN COLD AND WARM CONDITIONS WARNING Check that there are no persons or obstacles in the surrounding area, then sound the horn and start the engine. WARNING NEVER use starting fluid (such as ether) to help start the engine. This engine has a preheater in the intake manifold and this combination can cause an explosion. NOTICE: Do not keep the starting motor rotating continuously for more than 20 seconds. If the engine will not start, wait at least 2 minutes before trying to start the engine again. 1. Turn the key in the starting switch (1) to the ON position.
Preheating will automatically start and preheating pilot lamp (2) will light up. The table shown below gives a guide to preheating time. The preheating time in cold areas changes according to the water temperature when starting the engine. 2. Depress accelerator pedal (3) lightly. 3. Check that preheat pilot (2) lamp is out, then turn the key of starting switch (1) to the START position to start the engine. 4. When engine is started, release the key of starting switch (1) and the key will return automatically to ON . CAUTION: ! Do not idle the engine for 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 E C {140 E 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.
2-37 Temperature Preheating time Below -18EC (-2EF) About 30 seconds From -18E to -8EC(-2E to 17EF) About 20 seconds From -8E to 8EC (17E to 46EF) About 10 seconds Above 8EC (46EF) 0 seconds
