WARNING
q
If there has been any Emergency stop, abnormal actuation or trouble, turn the starting switch key to
the OFF position.
q
If the work equipment is operated without warming the machine up sufficiently, the response of the
work equipment to the movement of the control lever will be slow, and the work equipment may not
move as the operator desires, so always carry out the warming-up operation. Particularly in cold
areas, be sure to carry out the warming-up operation fully.
Warming-Up Operation
3
NOTICE
q
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 warm-
ing-up operation is completed.
q
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.
REMARK
If the hydraulic oil temperature is low, the hydraulic oil temperature monitor display will be white.
After starting the engine, do not immediately start operations. First, carry out the following operations and checks.
1. Turn fuel control dial (2) to center position (A) between the
low idling (MIN) and high idling (MAX) positions and run the
engine at a mid-range speed under no load until the engine
water temperature monitor gives a green display.
2. Set lock lever (1) to the FREE position (F) and raise the
bucket from the ground.
