After the engine starts, do not start operating the machine
immediately. First, carry out the following operations and checks.
1. Wait until the automatic warm-up operation is cancelled.
If the engine water temperature goes above 30 degrees C or if
the warm-up operation has been continued for more than 10
minutes, the automatic warm-up operation is cancelled and the
engine speed drops to the normal low idling speed.
2. Check that the engine coolant temperature monitor (1) displays
the correct temperature.
• (A) Display when temperature is correct: Monitor background
(C) is blue.
• (B) Display when temperature is low: Monitor background (C)
is white.
If it displays low temperature, use the procedure in Step 3 to
carry out additional warm up of the engine until the monitor
displays the correct temperature.
3. Turn fuel control dial (2) to a point midway between low idling
(MIN) and full speed (MAX), run the engine under no load at a
mid-range speed until engine coolant temperature monitor (1)
displays the correct temperature.
• (A) Display when temperature is correct: Monitor background
(C) is blue.
• (B) Display when temperature is low: Monitor background (C)
is white.
If the engine coolant temperature monitor displays the correct temperature, the engine warm-up
operation is completed.
After checking that the engine coolant temperature monitor displays the correct temperature, carry out
the warm-up operation for the hydraulic equipment.
[CANCELLING AUTOMATIC WARM-UP OPERATION]
If it becomes necessary in an emergency to cancel the automatic
warm-up operation or to lower the engine speed to low idle, do as
follows.
(1) Turn fuel control dial (2) to the full speed (MAX) position and
hold it for 3 seconds.
(2) When fuel control dial (2) is returned to the low idle (MIN)
position, the engine speed will drop.
