Manual Extract Fan reverse rotation function:

As the fan reverse rotation switch is pressed for cleaning of the radiator core, the cooling fan reverse rotation solenoid valve of the cooling fan motor is activated, reverse rotating the fan.

1. Fan manual reverse rotation function
The operator can select the fan rotation direction as he chooses by setting the fan reverse rotation switch to “MANUAL”.
As long as switching of the fan rotation direction is taking place, the pilot lamps of the fan reverser rotation switch and the machine monitor keep blinking to inform the operator that the switching is underway.
And when the fan rotation is reversed responding to the high engine speed, high coolant or oil temperature, this lamp also keeps on blinking until the preparation for switching is completed.

As the fan rotation switching condition is met, this function sends the accelerator opening ratio-restricting signal to the engine controller so that the engine speed may not reach 1,200 rpm or above while the switching is underway.
As long as the reverse fan rotation is continued, the pilot lamp of the fan reverse rotation switch and the machine monitor remains turned on.
