3.13 Machine operation
General safety instructions
• Machine operation is only allowed when seated on the seat
– see chapter 2.6 Safety instructions regarding operation on page 2-6.
• Do not use the machine in areas with falling object hazard!
• Never travel up to the edge of a pit from outside – cave-in hazard!
• Never undermine the foundations of walls – collapsing hazard!
• Do not dig under projecting ground. Stones or the projecting earth can fall onto the
machine.
• Do not excavate deeply under the front side of the machine. The ground under the
machine could collapse and cause it to tip over.
• In order to leave the control stand more easily under especially difficult circumstances,
position the tracks parallel to the roadside or to the uphill slope with the drive pinion
behind the operator.
• Do not perform demolition work below the machine, this could cause the machine to tip over.
• When working on roofs or similar structures, check the resistance and the structure
before starting work. The building can collapse, causing serious/fatal injury and serious
damage.
• Do not place the machine directly underneath the workplace during demolition,
otherwise demolished parts can fall onto the machine or the building can collapse,
causing serious/fatal injury and serious damage.
• Do not use the impact force of the attachment to perform demolition work. Falling
demolished parts (parts of buildings, for example) can cause injury and/or damage to
property and/or the machine.
• In general the machine is more liable to tip over if the boom is positioned laterally than
if it is positioned parallel to the longitudinal axis of the machine.
• The machine can lose its balance and tip over if a demolition hammer or other heavy
attachment is used. Proceed as follows to perform work both on level ground and on slopes:
☞Never lower, turn or set down the attachment abruptly.
☞Do not extend or retract the boom abruptly, otherwise the machine can tip over.
• Do not raise the bucket over the heads of persons, the seat or the cabs of trucks or
other means of transport. Material can fall out, or the bucket can knock against the
truck and cause serious/fatal injury and serious damage.
