INSTALLING AND CHECKING:
I Setting speedometer
1. Push the function key beside the display until
the display shows the driving speed.
2. The driving speed should be zero (0).
3. Push the key about 6 seconds, then release it.
4. To make the display smaller
:
---Push the key once. By pushing the key
immedia tely, the display shows the wheel cir-
cumference adjusting value which reduces at
every push.
To make the display greater
:
---Push the key once and wait about 6 seconds.
By pushing after, the adjusting value increases at
every push.
Adjust the circumference value according to
thetyresizeshownintablebelowbypushing
the key.
5. After the adjustment, the display shows auto-
matically the driving speed and the adjusting
value is in the memory. Note that the driving
speed must be in the display, when the adjust-
ment is started. The value direction can neither
be changed during the adjustment.
Setting speedometer has also to be done when
changing different size tyres or if it is wanted to
adjust the speedometer more exact for worn
tyres.

Table 1. The wheel circumference value which
is input into the speedometer can be calculated
as follows:
Rolling circumference
number of magnets (2)
x0,91
If tyre specifications are not available, you
can measure the wheel circumference as fol-
lows:
---Mark a mark on the tyre and on the ground.
---Drive the tractor forward until the wheel has
made 5 revolutions.
---Make a second mark on the ground.
---Measure the distance between the two marks
and divide this distance by 5. The result is the
effective circumference of the wheel.
