●
Never let the positive terminal (+) con-
tact with the negative terminal (-) when
connecting the cable.
●
Keep a normal machine away from
the faulty machine in order to prevent
sparks around the battery from burning

●
Avoid mistakes in connection of the
jumper cable. Its

the work tool shall be excluded as the
work tool is not a good conductor.)
●
When removing the jumper cables, pay
extra attention to the cables, whose
clips shall not contact with each other
or with the chassis.
