No additional interventions may be carried out on electric installation of the tractor
(connection of other electric consumers) due to its possible overloading!
With repairs of electric installation pay special attention in particular to manipulation with the battery
to avoid any contact of electrolyte with skin or clothing.
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 tractor 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
spontaneous start and endangering of the service
person's life).
It is forbidden to start the engine by short-
circuiting the starter motor terminals. Only start the
tractor from the driver's seat!
Accumulator battery
The accumulator battery is installed under the cover on
the left side of the tractor under the cab step. The battery
is accessible after folding up of the cab step.
During folding up of the cab step the cab door
must be closed.
