Operation 5
Rotating the upper carriage
Accident hazard! Upper carriage can rotate a little bit further.
Can cause serious injury or death.
► The upper carriage can rotate a little bit further as long as the hydraulic
fluid has not reached its operating temperature yet.
► If the machine is equipped with an extra weight (option), the upper
carriage projects beyond the tracks when it is rotated.
► Ensure that there are no obstacles in the immediate area before
rotating the upper carriage.
► If the joystick is moved further, the revolving superstructure rotates
quickly; If the joystick is moved less far, the revolving superstructure
rotates slowly.
► If the upper carriage is supposed to be rotated on a slope, operate the
control lever carefully to avoid fast movements.
