3.49 Working with the machine
General safety instructions
• Never drive up to the edge of a pit from outside – danger of cave-in.
• Never undermine the foundations of walls – danger of collapse.
• Do not work under projecting earth. 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 cab more easily under especially difficult circumstances, position
the tracks perpendicularly to the roadside or to the uphill slope with the drive pinion
behind the user.
• Do not perform demolition work below the machine, otherwise it can lose its balance
and tip over.
• When working on roofs or similar structures, check the resistance and the structure
itself before starting work. The building can collapse, causing severe injury and
damage.
• In general the machine is more liable to tilt if the boom is positioned laterally than if it is
positioned at the front or rear of the machine.
• Do not move the attachment across the heads of workers or across the cabs of trucks
or of other means of transport. Material can fall out, or the attachment can knock
against the truck and cause severe injury or damage.
• Operation of the machine by unauthorized personnel is prohibited.
• Look out for high-voltage cables, underground cables, gas and water pipes during
excavation work.
• The hydraulic system of the machine is still pressurized even when the engine is not
running. Therefore release the pressure in the sections of the system and hydraulic
lines which are to be opened before starting setup or repair work, for example fitting/
removing an attachment with hydraulic functions
– see chapter 3.56 Releasing the pressure on the operating hydraulics on page 3-102.
