Safety instructions
2.12 Hammer operation
• Contact your Wacker Neuson dealer for information on the correct equipment.
Safety instructions
• If there is a risk of falling or projected objects, an operator safety shield must be
installed.
• During operation, all persons must stay clear of the work area of the machine.
• Do not place the machine directly underneath the workplace during demolition,
otherwise parts can fall onto the machine or the building can collapse.
• Do not perform demolition work below the machine, this could cause the machine to tip
over.
• The machine can lose its balance and tip over if a hammer or other heavy attachment is
used. Proceed as follows to perform work both on level ground and on slopes:
• Never turn, lower or set down the attachment abruptly.
• Do not extend or retract the boom abruptly, otherwise the machine can tip over.
• Stop work immediately if a hydraulic hose moves back and forth in an unusual manner.
This could be a cause for a pressure accumulator defect. Contact your Wacker Neuson
dealer and have the error repaired immediately.

the edge or start again in another place in order to break the material.
• Do not put the hammer into operation if a hydraulic cylinder is fully extended or
retracted.
