OPERATION
NOTICE
When the hydraulic oil is at a low temperature, do not
G
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 warm-
G
ing-up operation is completed.
Do not run the engine at low idling or high idling continu-
ously for more than 20 minutes. This will cause leakage
of oil from the turbocharger oil supply piping. If it is nec-
essary 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 (1) at the low idling (MIN) position and run
the engine for about 5 minutes without load.
2. When the automatic warming-up operation is completed,
press working mode switch (2) on the monitor panel until the
heavy-duty operation mode lamp lights up.
3. Turn fuel control dial (1) to the mid-range speed position and
turn swing lock switch (3) ON.
