4.4

Emergency steering properties

If the engine fails while you are driving, you can still steer the
machine. However, you need to manually apply more power.

In case of engine failure, immediately drive to the side of the road,
switch on the warning lights and secure the machine.

4.5

Emergency lowering

When the engine is not running, the work equipment can still be
lowered with the multi-function lever (emergency lowering).

If the hose break safety device is installed, the machine is
equipped with a pressure accumulator, so that the work unit can
be lowered by means of the multi-function lever when the diesel
engine is off.

NOTICE

If you have locked the work hydraulics (multi-function lever) by
means of the lock lever, you cannot lower the work unit.

1. Make sure that no one is standing under the machine.

2. Push the multi-function lever slowly to the position “S”.

The work equipment is lowered.
