Control

switch is forcefully brought into position '1'..

Function security

An interruption of the supply line or other control lines will not deactivate the immobilizer or delete data (e.g. data codes).. All relevant data are stored in a non-volatile memory. Magnetic fields will not deactivate the immobilizer.

3.4Working with the machine

3.4.1The travel movements

Straight travel

1 Idler wheel

2 Sprocket wheel

Caution!

5 Left travel pedal

6 Right travel pedal

When travelling the machine, the upper carriage must be rotated to the undercarriage in such a way that ,during forwards travel, the idler wheel 1 is in front and the sprocket wheel 2 is at the rear.

Travelling forwards:

Push the both travel pedals forwards (5a + 6a).

Travelling backwards:

Push the both travel pedals down (5b + 6b).

Caution!

Before you travel in reverse, make sure the area behind the machine is free of any obstacle and nobody is in your way.

Turning over one track

Turning right:

Push the left travel pedal 5 forwards (5a).

Turning left:

Push the right travel pedal 6 forwards (6a).

Note!

Avoid turning over one track in reverse, this exposes the track drive components to increased strain.

Counter rotation

Turning right: Push the left travel pedal 5 forwards (5a), ... ... and at the same time push the right travel pedal 6 down (6b).

Turning left: Push the right travel pedal 6 forwards (6a), ...

... and at the same time push the left travel pedal 5 down (5b).

Danger!

Pay attention that, if the uppercarriage is turned by 180° to the undercarriage, all the travel lovements are inverted (left and right, forwards and backwards)!

Levers for manual control of travel movements

These levers allow a more sensitive control of the travel movements, they are installed to the travel pedals at machine delivery. If not used, they can be removed and stored inside the cab.

Each time when a particularly sensitive control is required, insert the levers into the travel pedals and operate the travel movements manually.

Travel speed preselection

The travel motors can be operated in two different positions:

– travel in normal speed (position 1): The obtained track forces are maximum while the travel speed is moderate.

– travel in increased speed (position 2): The track forces are reduced and the travel speed is maximum.

The preselection between the both positions is realized via the touch S21 Depressing the touch causes the integrated LED 1 to light up and go off alternately.

When the LED 1 in the touch S21 is off.

–The travel motors remain all the time in position 1 (normal speed).

When the LED 1 in the touch S21 is lighting.

–During travel, the oil motors mounted to the travel gears now change automatically from normal speed to increased speed each time the terrain conditions allow it.

–After changeover to position 2 (increased speed) the LED 2 illuminates.

–Inversely, when ground conditions become difficult again, the travel motors automatically return to position 1 (normal speed). The LED 2 turns off.

The travel brakes

The travel drive of your machine is fitted with two different braking systems. In the both systems, the releasing and the applying of the brakes occurs automatically when depressing and returning to neutral the travel pedals.

The hydraulic operating brakes

When the travel pedals are released, they automatically return to neutral position. This causes the hydraulic brakes valves 6 mounted to the travel motors to react and a rapid braking of the machine is achieved.

Caution!

Disengaging the travel pedals quickly causes the machine to halt abruptly. When ever possible, return the pedals to neutral progressively, in particular on machines which are equipped with very long working attachments or when they hold up a heavy load.

When these machines come to standstill too brutally, important forces of inertia are generated, which can endanger the stability of the machine.

The hydraulic brake valves also avoid overspeeding and run away of the machine when travelling down a slope.

Fig. 3-62 Arrangement of mechanical brakes 5 and hydraulic brake valves 6

The mechanical stop and parking brake

A negatively acting, hydraulic operated multi-disc brake 5 is integrated in each travel gear.

When a travel pedal is actuated, hydraulic pressure builds up in the corresponding travel circuit and releases the brake. Inversely, when the travel pedal is returned to neutral position the pressure is annuled and the brake applies again.

3.4.2Cable winding drum (option)

The cable drum is mounted at the rear of the

undercarriage.

Note!

Before any use, see cable drum operation manual.

Danger!

As long as the main isolating switch is not opened and locked out, the power cable, the cable drum and the switch cabinet remain powered.

Description of operating and control elements

Operating and control elements are located in the following locations : –on an outside control box, on the cable drum. –on the right control desk, on the cab.
