• The chosen method will depend on the situation and can be tested by checking whether a
traction difference can be observed even when the traction levers are not operated (i.e. with
the pumps in zero position).
• When the rollers touch the surface, the weight of the machine will prevent you from observing
a small traction difference in neutral status. That difference can however, be noticed when the
rollers are idle.
• Draw a straight chalk line across both rollers; this will allow you to monitor the traction
difference.
• Start the engine.
Caution:
Do not touch the All-in-one

control lever: the blades are on the surface!
Engaging the blades at this point would cause serious damage to the blades and
to the surface.
• Check the effect on both rollers. In the neutral position, it will be easy to observe which roller
causes the deviation.
• To adjust the neutral position at the relevant side
of the pump, slightly loosen the two bolts (M6) of
the fixing plate (spanner size 10). Very carefully
move the plate to slightly move the neutral point.
• Proceed until the traction difference is gone.
• Tightly secure the tension bolts (M6) again.
• Adjusting the zero point on the hydrostatic pump will have an effect on the cruise control
setting. Readjust it if necessary.
11.4.10 Changing hydrostatic oil
The hydrostatic circuit is a closed system, fully shielded against dirt. The hydrostatic suction
tube also contains a filter to avoid any dirt from entering the pump. Despite these provisions, we
recommend to change the oil after 500 hours of operation. Proceed as follows:
