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 3O”C), the warming-up operation is carried out automatically.
The automatic warming-up operation is canceled if the engine water
temperature 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 operation, warm the engine up further as
follows.
NOTICE
l 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.
l 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 from 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 a mid-range speed.
1. Set fuel control dial @to the low idling (MINI position and run
the engine for about 5 minutes without load.
