NOTICE
• Do not accelerate the engine abruptly until it is
warmed up.
Do not operate the starting motor continuously for
more than 20 seconds.
• If the engine does not start, wait for 2 minutes or so,
and then try to start the engine again.
This machine is equipped with an engine automatic preheating
device that functions to start the engine preheating automati-
cally.
When the ambient temperature is low, the preheating pilot lamp
(2) lights up when the key in starting switch (1) is turned to ON
position to inform the operator that preheating has been started
automatically.
1.
Turn the key in starting switch (1) to ON position (B).
When the ambient temperature is low, preheating pilot
lamp (2) lights up and automatic preheating is performed.
Keep the starting switch key (1) at ON position until pre-
heating pilot lamp (2) goes out.
The time that preheating pilot lamp (2) stays lit depends on
the ambient temperature as shown in the table.

REMARK
Usually, the engine is preheated sufficiently by the automatic preheating. If it is needed to extend the pre-
heating time, turn the key in starting switch (1) to position (D).
Do not preheat the engine more than 40 seconds, however.
2.
When preheating pilot lamp (2) does not light up, turn the
key in starting switch (1) to START position (C) after the
engine preheating has been completed.
The starting motor keeps running to start the engine.
Keep the key in starting switch (1) at position (C) to keep
running the starting motor until the engine starts.
REMARK
When the ambient temperature is low, fuel is not supplied
to the engine for 3 seconds to ensure lubrication of the en-
gine and to improve the durability after the key in starting
switch (1) is turned to START position (C), so the engine
does not start during this time.
