BASIC SERVICE INFORMATION
The battery must always be connected with the “minus” pole to the ground and with
the “plus” pole to the alternator. If the battery is connected the other way round, it will
destroy the whole semiconductor equipment of the alternator. When starting the trac-
tor with the use of an auxiliary battery, do not forget to connect the terminals “plus” to
“plus” and “minus” to “minus”. If you replace a part of the charging circuit, disconnect
the battery from the tractor ground (-) with the battery disconnector. This way you will
avoid accidental short-circuits on the terminals.
In case of any handling or repair of the started motor the minus pole of the
battery must be disconnected and all the shifting levers, incl. the PTO shifting
lever, must be in the neutral position (do not forget to check whether the
locked PTO switches on the right cabin pillar are off as well to prevent spon-
taneous start and endangering of the service person's life).
It is forbidden to start the engine by short-circuiting the starter motor termi-
nals.
Only start the tractor from the driver’s seat!
