4.1 Safety
Cleanliness is mandatory at all works with
the hydraulic system. Foreign substances
and contaminations will jeopardize the func-
tion and reliability of the system.
4.2 Description
The hydrostatic transmission (HST) consists of
a hydraulic pump and a hydraulic motor.
The hydraulic pump is mechanic connected to
the drive belt.
The powerfrom the pump is transmitted to the
motor by an oil flow, i.e. the transmission is
hydraulic.
The hydraulic motor is mechanic connected to
the wheel shaft.
Since both the oil flow and the flow direction is
controlled by the drive pedal, the machine can
move both forwards and backwards with a
stepless gear ratio.
4.3 Repair
Since trouble with the HST is very unusually,
there is no need for any repair instructions in
this book.
However, in some cases oil lekage can occur.
Therefor, the oil filling procedure is described
below.
Should major repair to the HST be needed,
please refer to the service provided of the
transmission manufacturer.
