REMARK
If the ambient temperature is low, the engine may not start even when the key in starting switch (1) is
kept at START position for 20 seconds.
In such case, return the key in starting switch (1) to OFF position once, then in approximately 2 minutes,
repeat the operation from the start.
If the starting switch is not returned to OFF position, the automatic preheating does not operate.

After the engine starts, release the key in the starting switch (1).
The key in starting switch (1) automatically returns to ON
position (B).
REMARK
At starting of the engine, battery voltage may drop abruptly
depending on the ambient temperature or battery condi-
tion, and the machine monitor may go out temporarily or
restart, but it is not a trouble.
5.
Do not operate the accelerator pedal immediately after
starting the engine. Run the engine for at least 15 seconds
at low idle.
When the engine is started for the first time after the engine oil or engine oil filter is replaced, continue the
low idle run for at least 20 seconds to circulate the engine oil in the engine.
METHOD FOR MANUAL PREHEATING WHEN STARTING ENGINE
Manual preheating of the engine is available regardless of the
ambient temperature.
1.
Turn the key in starting switch (1) from OFF position (A) to
PREHEAT position (D).
The preheating pilot lamp on the machine monitor (2)
lights up and preheating of the engine starts. (Preheating
continues while the key in starting switch (1) is held coun-
terclockwise.)
While preheating is being performed, the preheating pilot
lamp lights up to indicate that the preheating is being per-
formed.
