If the ambient temperature is low, the preheating monitor lights
up and automatic preheating is carried out. Keep the key in
starting switch (3) at ON position (B) until the preheating
monitor goes out.
The time that the preheating monitor stays lighted up depends on
the ambient temperature as shown in the table on the right.

then goes out to inform that the engine preheating has been
completed, turn the key in starting switch (3) to the START
position (C) and start the engine.
REMARK
If the ambient temperature is low, the engine may not start even
when the key in the starting switch (3) is kept at the START position
for 20 seconds. If this happens, wait for at least 2 minutes, then
start again from the beginning.
5. After the engine starts, release the key in starting switch (3).
The key will automatically return to ON position (B).
REMARK
When the engine is started, the battery voltage may suddenly drop
depending on the temperature and the battery condition. If this
happens, the display on the machine monitor may momentarily go
out, but this does not indicate any abnormality.

monitor to go out. Do not touch the control levers or control
pedal while the engine oil pressure monitor is lighted up.
NOTICE
If the engine oil pressure monitor does not go out even after 4 to 5 seconds
have passed, stop the engine immediately. Check the oil level, check for
leakage of oil, and take the necessary action.
