Basic service information
Accumulator battery must be always connected by a 'minus' pole to earth electrode and 'plus' pole connected
with alternator. Reversely connected accumulator battery will destroy the whole of semiconductor device of
alternator. When using auxiliary accumulator battery for starting the tractor, do not forget to connect 'plus' to
'plus' and 'minus' to 'minus'. If replacement of a part of charging circuit is done, disconnect a battery from the
earth electrode of the tractor by battery disconnector (-). Any incidental short circuits on clamps are
excluded.
With any manipulation or starter repair, it is necessary to disconnect the minus pole of the
battery and to shift all the levers including PTO shaft shifting lever to neutral position so as to
prevent spontaneous start and endangering the life of a repairman.
It is forbidden to start by short circuiting the clamps of starter. Start tractor only from driver's
seat.
Attention! When the engine is switched off, the engine control unit remains active for about
1 minute because of storage of operation data. During this time the supply of current from the
accumulator must not be interrupted. Do not disconnect the accumulator before this time expires.
Accumulator battery
Accumulator battery is located in a box on the left side of
the tractor. After unscrewing the screw marked with an
arrow, lid of box of accumulator battery can be opened
together with steps.
Battery disconnector
Accumulator battery is located under the cab on the right
side. Battery disconnector (1) is located on the right side
of the tractor in front of the cab.
a - Battery connected
b - Battery disconnected
If the tractor is put aside for a longer period of
time, it is necessary to recharge the accumulator at
least once in three months because of the battery self
discharge. When putting tractor aside we recommend
you to disconnect the accumulator by means of
battery disconnector.
Attention! When the engine is switched off, the engine control unit remains active for about
1 minute because of storage of operation data. During this time the supply of current from the
accumulator must not be interrupted. Do not disconnect the accumulator before this time expires.
