Operating manual

Working with the machine

This selection determines pressure and oil flow adjustment in the hydraulic circuit, depending on the function and the size of the auxiliary user. A wrong selection could lead to damage or unsatisfactory operation of the additional attachment. Note! The selection of the attachment does neither have an influence upon the allocation of the pedals, nor lead to the switching-off of pedal function.

Danger! Additional pedals may have many functions. They are describe on the operating sign in the cab, on the window on attachment side. Always check pedal’s functions when you start up a machine fitted with additional attachments.

Control of the other additional attachments The additional pedal 9m/9k allows to control optionaly mounted additional attachments. These additional attachments are, for example: • a hydraulic adjustable boom A • a hydraulic offset boom B • a concrete breaker or a rock crusher C • a scrap shear D When two of these additional attachments are mounted simultaneously on the machine, the first is controlled by the left double pedal 9m/9k, and the second is controlled by the right double pedal 9n/9p.

Push down the foot pedal 9m (or 9n). The cylinder of the additional user is retracted. Push down the foot pedal 9k (or 9p). The cylinder of the additional user is extended.
