5.3.7 Operation – pendulum axle locking
• The pendulum axle locking is controlled by the
excavator brake; that is, upon engaging the
brake, the pendulum axle is automatically
locked.
• For special application cases, it is possible to
activate the pendulum axle locking independent
of the excavator brake.
• To do so, set switch for pendulum axle locking
to "ON" (38/62)
• The indicator light in the switch lights up red.
After completing the special work, set
switch for pendulum axle locking
immediately back to "OFF."
