12.3.2 IN COLD AREAS (AUTOMATIC WARMING-UP
OPERATION)
When starting the engine in cold areas, carry out the automatic
warming up operation after starting the engine.
When the engine is started,if the engine water temperature is low (below
30°C), the warming up operation is carried out automatically.
The automatic warming-up operation is cancelled if the engine water tem-
perature reaches the specified temperature (30°C) or if the warming-up
operation is continued for 10 minutes. If the engine water temperature or
hydraulic oil temperature are low after the automatic warming-up opera-
tion, warm the engine up further as follows.
NOTICE
•
When the hydraulic oil is at a low temperature, do not carry out
operations or move the levers suddenly. Always carry out the
warming-up operation. This will help to extend the machine life.
•
Do not suddenly accelerate the engine before the warming-up
operation is completed.
•
Do not run the engine at low idling or high idling continuously
for more than 20 minutes. This will cause leakage of oil form the
turbocharger oil supply piping.
If it is necessary to run the engine at idling, apply a load from
time to time or run the engine at mid-range speed.
