High voltage is lethal and the current sufficiently
strong to destroy both machine and attachments.
Your life is in danger if you come into contact with
or close to high voltage power lines. Always contact
the power company responsible before beginning
any work near high voltage power lines. Go through
the special instructions issued by the power
company for work/presence near the power lines.
Regard all power lines as if they were live even if
they are supposed to be without current. Working
when the machine or its load at any time is closer
than the minimum safety distance to a power line,
is taking a very serious risk.
Remember that the voltage of the power line
determines the safety distance. Electrical flash-
over may occur and damage machine and
operator at fairly great distances from the power
line.
Voltage Minimum distance to
power line
0 ~ 50 kV 3 m (10 ft)
50 ~ 69 kV 4.6 m (15 ft)
69 ~ 138 kV 5 m (16.4 ft)
138 ~ 250 kV 6 m (20 ft)
250 ~ 500 kV 8 m (26 ft)
500 ~ 550 kV 11 m (35 ft)
550 ~ 750 kV 13 m (43 ft)
750 kV~ 14 m (46 ft)
NOTICE
The operator should have secure visibility when
working around the power lines.
NOTICE
When transporting the machine also take overhead
power lines into consideration.
