General safety instructions
Avoiding cave-in or collapse:
• Do not operate at the edge of an open excavation.
• Do not undermine wall foundations.
Preventing tip-overs:
• Do not excavate deeply under the front side of the machine. The ground
under the machine could collapse and cause the machine to tip.
• Do not perform demolition work below the machine.
• Doing so can cause the machine to tip over.
• In general the machine is more likely to tilt if the attachment is positioned
laterally than if it is positioned at the front or rear of the machine.
• The machine can become unstable and tip if a demolition hammer or
other heavy attachment is used. To perform work both on level ground
and on slopes:
• Do not move the attachment rapidly in any direction.
• Avoid use on slopes.
Avoiding falling debris:
• Do not create an overhang above the excavator.
• Do not create an overhang of debris during demolition.
• Install a front guard when working in areas with a risk of objects falling
from the front (e.g. demolition work).
Increasing operator safety:
• In order to leave the cab more easily under especially difficult circum-
stances, position the tracks perpendicularly to the roadside or to the uphill
slope with the drive pinion behind the driver.
• Prior to working on the structure surface, confirm that the floor or roof of a
building is strong enough to support the excavator and any loads lifted by
the excavator.
• Do not raise the bucket over the heads of other workers or over the driver
seats of trucks or of other means of transport. The material can tilt, or the
bucket can knock against the truck and cause severe injury or damage.
• Operation of the machine by unauthorized staff is prohibited!
• The hydraulic system of the machine is still pressurized even when the
engine is not running! Release the pressure in the sections of the system
and hydraulic lines which are to be opened before starting setup or repair
work, e.g. fitting/removing an attachment with hydraulic functions
Lowering the boom with the engine stopped on page 3-42.
• Never lower, turn or set down the attachment abruptly.
• Do not extend or retract the main boom cylinder abruptly, otherwise the
machine can tip over.
Preventing equipment damage:
• Do not use the impact force of the attachment to perform demolition work.
Dislodged debris can cause personal injury or damage to property and/or
equipment.
Look out for high-voltage cables, underground cables, gas and water pipes during excava-
tion work!
