Control and operation

The uppercarriage rotates to the left.

Push the joystick to the right d: The uppercarriage rotates to the right.

Braking the uppercarriage

Themachineisequippedaswellwithanhydraulicaswithamechanicalswingbrake.

The hydraulic swing brake

Let the left joystick move back to neutral position. The hydraulically swing braking of the uppercarriage takes place. In normal working conditions, the braking efficiency is sufficient to bring the uppercarriage to a standstill rapidly.

Move the left joystick in the opposite direction. The maximum hydraulic braking actionof the uppercarriage is achieved.

The mechanical swing brake

Themechanicalbrakeisanegativelyactingmultidiscbrakewhichisintegratedinthe swing gear. It allows to stop the uppercarriage in any desired position (for parking, when working on a slope, ...).

Press "Swing brake" button S17 Swing brake is applied. LED in the button illuminates.

Press the button again. Swing brake is released. LED in the button goes out.

Caution!

To stop the uppercarriage when working on a slope: Use the joystick to reduce the uppercarriage speed. Press button S17 to operate the swing brake. Move the joystick back to "0" position only after the brake operates.

To check the mechanical swing gear brake: When the uppercarriage is stationary.

Press button S17 to apply the mechanical swing brake

Push the left joystick to the right and then to the left as far as the stop. If the swing brake function is OK, the uppercarriage does not start swinging.

Semi-automatic swing brake control (optional equipment)

Press button S17 to release the swing brake. LED in the button goes out. The swing gear brake is in mode semi-automatic and can now be controlled as follows by the rocker switch S57:

Tilt down the rocker switch S57 on the joystick handle.

Tilt up the rocker switch S57. The brake remains released permanently.

Emergency stop of the uppercarriageswing motion

The swing brakecan beappliedindependently oftheuppercarriage RPM by switching the "Swing brake" button S17 to position "applied".

Caution!

Perform this brakingvia "Swingbrake" button S17 only exceptionally, i. e. in emergency cases, since it causes fast abrasion of the brake discs.

The positioning swing brake (optional)

The positioning swing brake is used for progressive and sensitive braking of the uppercarriage.
