OPERATION
EXPLANATION OF COMPONENTS
3-21
REMARK
The fan rotation direction cannot be changed, even if it is tried
when the engine is running.
The fan operation confirmation lamp begins to flash to tell you
that the fan rotation direction cannot be changed.
When the fan operation check lamp lights up and the fan is
turning in the reverse direction, the machine does not start
even if the steering - forward / reverse shifting- gearshift lever
is operated to the FORWARD or REVERSE position. This is to
protect the radiator. To start the machine, turn the engine start-
ing switch key to the OFF position once and then turn to the
ON position once again, after making sure that the fan opera-
tion check lamp has gone off.
When the fan is turning to clean the radiator fins, and the
engine starting switch is turned to the OFF position, power is
not switched off immediately in order to protect the hydraulic
circuit.
