 Before connecting two machines with booster cables:
 Turn the starting switch of the faulty machine to the OFF
position.
 Only switch the battery main switch of the faulty machine
off once the green pilot lamp on the relay box has gone
out.
 Switch the starting switch of the functioning machine off.
There is a risk that the faulty machine will move when the
power is connected.
 Avoid short circuits with the battery poles or the battery termi-
nals by accidentally touching them with metal objects, e.g.
tools.
 Always disconnect the negative (-) terminal (ground side) first
when removing the battery; when installing the battery, con-
nect the positive (+) terminal first, and connect the ground
last.
 Attach the battery terminals securely. Loose battery terminals
can cause sparks and lead to an explosion. Make sure that
the cover for the positive (+) terminal is mounted at all times.
 Tighten the battery caps securely.
 Remove the negative (-) terminal from the battery during
repair work of the electric connections or during electric weld-
ing, to disrupt the electricity flow.
