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 range of the machine.
• Do not place the machine directly underneath the workplace during demolition,
otherwise debris 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.
Working with a hammer
NOTICE
Always observe the following instructions:
• Do not use the impact force of the attachment to perform demolition work.
• Keep the hammer perpendicular to the surface (max. deviation to all sides is
2°).
• Never move the hammer as you drive it into the material.
• After you have driven the hammer into the material, do not try to fragment the
material with movements to the sides.
• Do not operate the hammer in the same spot uninterruptedly for more than 15
seconds.
• If the applied impact force does not break the material, move the hammer to
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.
• Never use the hammer horizontally or upward.
• Do not use the hammer for catching or collecting material.
• Press the hammer firmly against the material to avoid hammer operation with-
out any resistance.
• Do not use the hammer to raise loads.
• Do not hit the hammer-body against rocks, concrete, etc.
• Do not raise the machine with the boom.
• Do not perform any movements with the machine during hammer operation.
• Working with the hydraulic cylinders and/or the boom fully extended is prohib-
ited.
