Setting the fan speed on the oil flow control valve of the tractor
The pressure relief valve (Fig. 77/2) returns oil
volumes, larger than necessary, back into the oil
tank and unnecessarily heat up the hydraulic oil.
The fan speed is changing until the hydraulic oil
has reached its operational temperature.
At the first use the fan speed should be corrected
until the operational temperature has been
reached.
When the fan is operated after a prolonged peri-
od of standstill again the pre-set fan speed will
only be reached when the hydraulic oil has
reached its operational temperature.
On tractors with controllable hydraulic pump (Fig.
77/1) set the fan speed on the oil flow control
valve:
1. Close the pressure relief valve (Fig. 79/2)
(turn clockwise) and then open ½ turn (see
chapter ), so that the oil volume is as little
as possible.
2. Set the necessary fan speed on the oil vol-
ume control valve of the tractor.
3. The blower fan rev. speed is displayed in
the menu operation.

/2) of the
machine:
1. Remove protective cap (Fig. 7

/1)
2. Slacken counter nut
3. Use a screw driver to set the speed on the
valve as follows:
Turn to the right
= Increase fan speed
Turn to the left
= Reduce fan speed
4. After setting, secure the valve position us-
ing the counter nut and put on the protec-
tive cap (Fig. 79/1).
The blower fan rev. speed id displayed in
the menu machine date (see chapter,) and
in the menu operation.
