Within this Manual, “work near electric lines” means
when the attachment or load raised by the excavator

national safety regulations concerning work near
electric lines are observed.
Prior to beginning the work near electric lines:
- Contact the Company owner of the electric lines or
its nearest branch before starting the work.
Look up the in the telephone directory.
- Define together with the Company representative
which precautions should be taken to guarantee
work safety.
- All electric lines should be considered as operative
live lines even though it might be well known that

precautions.
- Decrease work speed. Reaction time could be too
slow and distance evaluation wrong.
- Warn all ground personnel to keep clear of the
machine and/or load at all times. If the load has to
be guided down for laying, consult the Electric
Power Company to know which precautions should
be taken.
- Appoint a person in charge of signalling duties.

undivided attention to the signals supplied.
When working in or near pits, in ditches or very high
walls, check that the walls are sufficiently propped up
to avoid cave-in hazards.
Pay the utmost attention when working near overhang
walls or where landslides may take place. Make sure
that the support surface is strong enough to prevent
landslides.
W h e n d i g g i n g , t h e r e i s t h e r i s k o f c a v e - i n s a n d
landslides.
Always check ground conditions and conditions of the
material to be removed. Support everywhere it is
required to prevent possible cave-ins or landslides
when:
- digging near previous trenches filled with material,
- digging in bad ground conditions,
- digging trenches subject to vibration from railroads,
working machines or highway traffic.
STOPPING
When the machine is to be stopped for whatever
reason, always check that all controls are in the
neutral position and that the safety lever is on the lock
position to guarantee risk-free start-up.
Never leave the machine unattended with the engine
running.
Prior to leaving the driver’s seat, and after making
sure that all people are clear of the machine, slowly
lower the attachment until resting it safely to the
ground. Retract possible auxiliary tools to the closed
safety position.
Check that all controls are in the neutral position.
Move engine controls to the shut-down position.
