High-speed mode

The slewing gear cannot be operated at high speed.
You can switch on the high-speed mode for a higher speed.
Risk of accidents due to the suddenly accelerating movements!
Reduce the engine speed before starting high-speed mode.
This will prevent movements from becoming excessively accelerated,
which may result in the truck crane starting to sway and overturning.
The High speed function will only be enabled if the carrier ignition is
switched off.
•
Turn off the carrier ignition, if necessary. Push the button (1) up once.
The lamp in the button should go out.
High-speed mode is always switched on and off for the derricking gear and
the telescoping mechanism at the same time.
To switch on briefly
•
Press button (1) down on the right – inwards.
High-speed mode will be active until you release the button.
Continuous operation
•
Press button (1) down on the left – outwards.
High-speed mode will be enabled until you press the button again.
Lamp (1) indicates the current status:

When lowering the boom, high-speed mode only supports the start of the
derricking procedure from steep boom positions. It does not increase the
derricking speed.
High-speed mode is disabled for raising when performing operations with
the lattice extension.
