OPERATION
OPERATIONS AND CHECKS AFTER STARTING
ENGINE
Emergency stop
●
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
●
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.
WARMING UP OPERATION
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 warm-
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 necessary to run the engine at idling, apply a load
from time to time or run the engine at a mid-range speed.
REMARK
If water temp is above 30°C, to protect the turbocharger, the
engine speed does not rise for 2 seconds after starting, even if
the fuel control dial is turned.
If the hydraulic oil temperature is low, the hydraulic oil tempera-
ture 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 (7) to the centre position between LOW
IDLING (MIN) and HIGH IDLING (MAX) and run the engine at
medium speed for about 5 minutes with no load.
