Komatsu HB365LC-3, Operation & Maintenance Manual

Page: 255 / 506

Run the engine with no load until the engine coolant tempera-
ture caution lamp (1) displays the correct temperature.
• Display (A) when temperature is correct: Caution lamp
background (C) is blue.
• Display (B) when temperature is low: Caution lamp back-
ground (C) is white.
If the engine coolant temperature caution lamp displays the correct temperature, the engine warm-up operation
is completed.
Then, perform the warm-up operation for the hydraulic components.
METHOD FOR CANCELLING AUTOMATIC WARM-UP OPERATION
When you are forced to urgently cancel the automatic warm-up
operation or to lower the engine speed to Low idle (MIN), do as
follows.
1.
Turn the fuel control dial (2) to High idle (MAX) position
and hold it for 3 seconds or more.
2.
Turn the fuel control dial (2) to Low idle (MIN) position.
The engine automatic warm-up is cancelled, and the en-
gine speed is lowered.
REMARK
Turbo protect function takes priority over the engine automatic warm-up operation.
When the turbo protect function activates, run the engine at low idle even the engine coolant temperature is
30 °C or less. Then the engine automatic warm-up starts automatically to increase the engine speed.
For details of the turbocharger protect function, see “METHOD FOR STARTING ENGINE (3-177)”.
