Hazards of use
WARNING:
The absence of
instruction, or the inadequate
imparting of instruction, can
lead to incorrect or adverse use,
and can give rise to accidents
with far-reaching human,
material, financial and environ-
mental consequences.
Precautions:
All users must follow the safety
directions given by the
manufacturer and the directions
of the person responsible for the
instrument.
CAUTION:
Watch out for erroneous
measurements if the instrument
is defective or if it has been
dropped or has been misused or
modified.
Precautions:
Periodically carry out test
measurements and perform the
field adjustments indicated in
the User Manual particularly
after the instrument has been
subjected to abnormal use and
before and after important
measurements.
DANGER:
Because of the risk of
electrocution, it is very
dangerous to use levelling staffs
and extensions in the vicinity of
electrical installations such as
power cables or electrical
railways.
Precautions:
Keep at a safe distance from
electrical installations. If it is
essential to work in this
environment, first contact the
safety authorities responsible for
the electrical installations and
follow their instructions.
