Operating instructions

Operation

Caution! The safety lever must always be pushed up into its highest position (see arrow) when entering or exiting the cab. When the safety lever is pushed up, the pilot control pressure is interrupted. This means that: – No work movements can be carried out when pilot control devices, e. g. the joystick or foot pedals, are operated. – The slewing gear brake will engage (indicator light in switch S17 illuminates). – It is not possible to release the slewing gear brake using switch S17. By moving the safety lever to its lowest position, the original switching states of the slewing gear brake and its switch S17 will be recreated and the pilot control devices are active. Before starting work from the operator's seat, the safety lever must be pushed to its lowest position.
