Hydraulic System

The control elements, with the exception of the dozer blade lever, the boom swing pedal, the extra circuit pedal and
the drive levers, activate a hydraulic oil pilot circuit.

The dozer blade lever controls the valve via a Bowden cable.

The accumulator (

) allows the boom and arm to be lowered if the engine has stalled.

The hydraulic oil reservoir contains the intake filter and the return filter.

Radiator and Oil Cooler

The radiator and the oil cooler are located under the side cover.

Radiator

Oil cooler

Tank vent filter

NOTE

Do not open the closing plug (4) on the tank vent filter. No maintenance of the tank vent filter is necessary.

Gauge glass for the level of the hydraulic oil

Accumulator

Oil fill opening for hydraulic oil

Valve block

Reservoir for hydraulic oil

Hydraulic oil pump
