Battery connection
– The battery terminals must never be confused. Each terminal is
clearly marked with a (+) or a (-) sign respectively. If the cables
are wrongly connected, the alternator rectifier will be ruined im-
mediately.
– When disconnecting batteries, first break the circuit using the
battery master switch. See Master switch on page 148.
Electric welding
– Before electric welding is carried out on the machine or any at-
tachment installed to the machine, the current must be turned
OFF at the battery master switch.
– Before carrying out any electric welding on the machine, the
battery cables should be disconnected and the connectors
pulled out of the electronic control units.
– When disconnecting and reconnecting, the leads should be
without current (the battery master switch turned off).
– Connect the earth (ground) lead of the welding equipment as
close to the welding point as possible.
– Before welding, remove all paint from an area of at least 10 cm
(4 in) around the point of welding. Paint which is heated gives
off unhealthy gases.
– All paint decomposes when heated and forms a great number
of compounds, which may cause irritation and be dangerous to
ones health after repeated or prolonged exposure.
– In addition to the health hazard, the weld will be of inferior qual-
ity and strength, which, in the future, may cause the weld to
break. Therefore, never weld directly on a painted surface.
