  • Page 29: Brake System

    Description 4.2.4 Brake system Service brake/ inching The service brake is operated via a double pedal (4-8/3). It is a fully hydraulic wet lamella brake in the front axle. When stepping on the pedal, an inching leverage releases the drive pump pilot pressure into the tank and then builds up the hydraulic pressure in the main brake cylinder.

  • Page 30: Swivel Unit And Axle Support

    Description All movements of the telescope arm, the telescope, the bucket, the attachments and the quick-change device are controlled from the operator’s seat by pilot valves. These pilot valves provide continuous speed control from “slow” to “fast”. 4.2.9 Swivel unit and axle support Two single-acting swivel cylinders are fed by a separate gear-type pump via a servo valve.

  • Page 31: Swivel Restriction

    Description 4.2.13 Swivel restriction (option) The loader is equipped with a swivel restriction that prevents swivelling by more than 30° to the left and right while the telescope is extended. This swivel restriction can be enabled or disabled with a toggle switch in the dashboard (4-11/14).

  • Page 32: Overload Cut-Off

    Description - 1 red LED (4-5/A4) The telescope loader has exceeded its maximum permissible capacity. At the same time, a warning beep is heard (can be disabled: 4-5/arrow). The warning beep is enabled only when the unit is turned off and on again. To perform safe hydraulic movements only: retract telescope and move swivel unit to a straight forward position.
