OPERATION
OPERATIONS AND CHECKS AFTER STARTING
ENGINE
Emergency stop
G
If there has been any abnormal actuation or trouble, turn
the starting switch key to the OFF position.
If the work equipment is operated without warming the
G
machine up sufficiently, the response of the work equip-
ment 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 warm-
ing-up operation fully.
WHEN NORMAL
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-
ing-up operation is completed.
Do not run the engine at low idling or high idling continu-
G
ously 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.
