S08 MAINTENANCE
DISCONNECT THE STARTER CABLES
1. Disconnect the negative cable (-) first.
2. Then remove the positive (+) cable.
If the battery is replaced, make sure that the previous one
was the correct model. Check against the table below:
Engine Nominal Capacity (K20) Cold Test Icc
A.h A
N4.115
150 (Min) -180 (Best) 900-1000
N4.140
150 (Min) -180 (Best) 900-1000
CONNECT THE CABLES
1. Always connect first the positive lead (+) to the
positive terminal (+) of the battery.
2. And then the negative (-).
BATTERY ELECTROLYTE LEVEL
DANGER !
Never touch the battery electrolyte with bare fingers. The
diluted sulphuric acid solution burns skin and will pierce
clothing. Should this occur, immediately wash garments
with spring water. Obtain medical advice and assistance
without delay for burns.
ELECTROLYTE LEVEL CHECK
In general, detailed informations for service provided by
battery manufacturers are very scarce. As a conservative
rule, electrolyte level must always be above the top of the
lead plates (+/-1 cm - slightly less than half of an inch).
Electrolyte is a mix of sulphuric acid and water. If level is
decreasing, acid concentration is not supposed to deplete
with evaporation. Water alone must be added, but it is a
good practice to check also the specific gravity with a
hydrometer. Follow these indications :
Unscrew completely the vent plugs and check level with a
flashlight in each and every orifice.
Use a syringe filled with distilled water to top up the
compartment where electrolyte level is too low.
Check gravity in each cell. A reading below 1.215 requires
either charging the battery or to replace it.
If the lead plates are not sulphated and still in good
condition, charging will improve specific gravity.
Specifi c Gravity Charge
1.260 100%
1.230 75%
1.200 50%
1.170 25%
1.140

1.110
Discharged
NOTE !
Never shake the battery during the process of adding
electrolyte !
If the battery electrolyte level cannot be adjusted
(maintenance free battery type), do not use or charge the
battery if the fluid level is below the lower limit level.
If the battery has been left unattended for an extended
period of time, it is likely that the battery has entered in
a deep discharge process. In such a case, voltage read
would be around 7 Volts or so.
