WARNING
Risk of injury when freeing casualties
When rescuing people trapped or injured by the device, there is a
risk of additional serious injury to the casualty if the hydraulic con-
nections were not connected according to their colour coding as

As a result, functions may run in the opposite direction or may be
inverted.
Before actuating the hydraulics, check that the hydraulic con-
nections of the device are connected to the tractor according to
the colour coding.
If there is no identification on the tractor and on the device or if the
