23. Cooling fan auto reverse rotation switch
(Option)
This switch (23) is used to rotate the cooling fan in the reverse
direction when cleaning the radiator.
Position (a): Auto reverse rotation function ON
The fan automatically rotates in reverse for 2 minutes every 2
hours. The pilot lamp inside the switch and the cooling fan
reverse rotation pilot lamp on the machine monitor light up.
Position (b): Manual reverse rotation switch ON
When the fan is rotating in the normal direction, if the switch is
pressed once, the fan will rotate in reverse; if the switch is
pressed again, the fan will rotate in the normal direction. When
the fan is rotating in the reverse direction, the cooling fan
reverse rotation pilot lamp on the machine monitor lights up.
For details of the procedure for cleaning, see "Clean radiator fins
and cooler fins (4-43)".
Position (c): Neutral (OFF)
The cooling fan is constantly set to normal rotation.
Run the engine at idling when operating the switch.
REMARK
When the direction of rotation of the fan is switched, the reverse
rotation pilot lamp flashes.
When the machine is operating under high load or in low tem-
peratures, the direction of rotation of the fan may not change.
This is to protect the machine.
When the engine is stopped, the fan returns to normal rotation.
When the switch is set to position (b) (Manual reverse rotation
switch ON), if the switch is released, it returns to position (c)
(Neutral). Even if the switch is not kept pressed at position (b),
the fan will continue to rotate in reverse direction for a certain
period, so there is no need to keep the switch pressed at posi-
tion (b).
