Operation
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 hammer in the same spot uninterruptedly for more than 15 seconds.
• Do not raise the machine with the boom.
• Working with the cylinders or the boom fully extended is prohibited.
• Do not swivel the Powertilt unit beyond 30° during hammer operation, oth-
erwise the load on the boom increases enormously.
• Stop machine operation immediately if a hydraulic hose moves back and
forth in an unusual manner. The pressure accumulator could be malfunc-
tioning. 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.
In order to ensure optimal functionality and to prevent the excavator from
overheating, take the following measure:
• Turn the handle of ball-type cock E (under the valve compartment cover)
toward G.
Switching on hammer operation:
Press hammer pedal 18 backward.
