The hydraulic drive generates a permanent op-
erating noise that gets louder when the load
(e.g. on steep terrain) is heavier. If the operat-
ing noise changes by becoming irregular or
very loud, let the hydrostatic drive cool down
and check the oil level.
If the changed operating noise persists, have
the device checked by an authorised service
centre.
It is possible that the hydraulic system must be
bled or the oil must be changed. For refilling,
only use fully synthetic engine oil 5 W50
