Operation

Changing the width of the stabilizer blade

NOTICE

Damage to machine when driving through doors, etc.

☞ Bear in mind the width of the stabilizer blade and of the telescopic travel gear when travelling through passages.

☞ Adjust the stabilizer blade and the telescopic travel gear to the same widths when operating the machine.

Reducing the width of the stabilizer blade

☞ Raise the stabilizer blade to about 1 – 2 cm (about 0.4 – 0.8 in).

☞ Pull out pins A on either side.

Operation

3.19 Telescopic travel gear

Crushing hazard due to tipping over of machine.

Causes severe crushing or injury resulting in death.

• Bear in mind the reduced stability of the machine with a retracted telescopic travel gear.

• Travelling with the retracted telescopic travel gear is only allowed for short passages.

• Position the boom upward when travelling uphill.

• Position the boom downward when travelling downhill.

• Raise the boom about 20 – 30 cm (8 – 12 in) off the ground and position it straight ahead at the center of the machine. In an emergency, lower the boom immediately to increase stability.

This prevents the machine from tipping over in case of a hose rupture on the telescopic hydraulic cylinder. A hose rupture might cause the travel gear to retract and reduce stability.

WARNUNG

Crushing hazard when retracting the telescopic travel gear.

Can result in severe injury or death.

• Do not allow anyone to stay in the danger zone.

NOTICE

In order to avoid damage to the machine when travelling through doors etc.:

☞ Pay attention to the width of the stabilizer blade and of the telescopic travel gear when travelling through passages.

☞ Adjust the stabilizer blade and the telescopic travel gear to the same widths when operating the machine.

Important

In order to achieve the best possible stability, lower the stabilizer blade, turn out the extensions (option) and extend the telescopic travel gear.

3.21 Parking the machine

Crushing hazard. Do not allow anyone to stay in the danger zone.

Risk of serious injury or death.

• Lock the upper carriage when transporting the machine.

• Lock the upper carriage when driving over longer distances.

The upper carriage lock prevents the upper carriage from rotating when driving the machine over longer distances, or locks the upper carriage during transport.

Locking the upper carriage

☞

Pull lever 2 from position

A to position B .

Unlocking the upper carriage

☞ Push lever

2

from position B to position A .

WARNUNG

Accident hazard. Always park the machine on firm ground.

Risk of injury.

• Place the machine on firm, level and horizontal ground.

• Position the boom straight ahead at the center of the machine and lower it.

• Lower the stabilizer blade to the ground.

NOTICE

Never stop the engine under full load, otherwise it can be damaged due to overheating.

☞ Let the engine run at idling speed with no load for at least 5 minutes before you stop it.

• Stop the machine.

• Lower the bucket and the stabilizer blade to the ground

• Reduce engine speed completely.

• Secure the machine against unauthorized operation.

• Raise the lock lever.

• Remove the starting key and carry it with you.

• Secure the tracks accordingly (e.g. chocks, etc.).
