Working with a hydraulic hammer
In order to avoid damage to the machine or hydraulic hammer, observe
the following points:
► Observe the Operator’s Manual of the hydraulic hammer.
► Never use the hammer horizontally or upward.
► Do not use the hammer to raise loads.
► Do not hit the hammer against rocks, concrete, etc.
► Do not use the hammer in the same spot uninterruptedly for more than
15 seconds.
► Do not raise the machine with the boom.
► Working with the hydraulic cylinders or the boom fully extended is
prohibited.
► Do not swivel the Powertilt unit beyond 30° during hammer operation,
otherwise the load on the boom increases enormously.
► Stop work immediately if a hydraulic hose moves back and forth in an
unusual manner. The pressure accumulator could be malfunctioning.
Contact a Wacker Neuson service center and have the malfunction
rectified immediately.
► Do not use the impact force of the attachment to perform demolition
work. Broken or falling pieces can cause damage to the equipment.
