Motion
The excavator moves with two groups made out of a hydraulic motor, brake and gearbox. The
movement function is controlled with a foot pedal, which controls both the forward and the
reverse motion, this function can be feathered. The machine has two speeds that can be
selected with a switch. The speed change is activated with the change of the hydraulic motor
displacement.
Max. speed in 1st gear::
Max. speed in 2nd gear:
The two groups can be set in neutral condition when the excavator must be pulled.
The two front wheels can be taken off by removing the locking pin.

Front tires:
Rotation
The rotation is achieved through a slew bearing moved by a hydraulic motor coupled with a
planetary gearbox and a negative stationary brake. The rotation speed can be feathered. The
dynamic braking is controlled by damp valves that limit the shocks to the structure.

Main control valve
The main pump feeds the 2 hydraulically piloted control valves, the control valves are
equipped with a maximum pressure valve located at the inlet and with anti-shock and anti-
cavitation valves on all sections;
The main control valve that controls the boom is a LOAD SENSING type.
Secondary control valve
1 electrically actuated control valve controls the under carriage functions.
Utility control at the boom nose
The machine is equipped with 2 tubes for the control of an utility:

Boom cylinders
All the boom cylinders are of double effect type and are equipped with end stroke shock
absorbers in both directions. The cylinders of the inner and outer boom can be equipped with
locking valves (Standard ISO 10567).
