Slow charge the battery
Special tools
Battery charger - constant current type with an output
of at least 14A and an upper voltage limit of 50V per
battery.
Charge procedure
Slow charge the battery as follows :
1. Remove the battery from the machine. Refer to
4003-5.
2. If a battery has been neglected and produces an
open circuit voltage of 11V or less, it will be
completely discharged and the plates will have
suffered sulphation. Initially the battery will draw
higher than normal voltage but lower than
specified current.
CURRENT FOR SINGLE BATTERY...............9A
CURRENT FOR TWIN BATTERY.................14A

CAUTION :
Parallel charging is not
recommended, therefore on machines fitted
with twin batteries, charge each one
individually.

3. Connect the battery charger to the battery. Make
sure the polarity of the connections is correct and
connect the (+) positive connection first.
4. After 30 minutes, check the charging voltage (the
charging current may still be lower than
specified).
Below 12V reject the battery.
Above 16V reject the battery.
Between 12 to 16V, continue with charging
process for 15 hours.
5. Set the battery charger to OFF. Disconnect the
cables from the battery. Make sure you
disconnect the (+) positive cable first.
6. Allow the battery to stand for 24 hours.
7.Load test the battery.
WARNING :
Check the battery temperature
regularly and if it reaches 60
°
C (140
°
F) stop
the charging process.
