Battery cleaning
The battery should always be kept clean, especially on its top side, and the terminals should be coated
with Vaseline.
CAUTION
NEVER USE FUSES WITH A CAPACITY HIGHER THAN THAT RECOMMENDED.
USING A FUSE OF UNSUITABLE RATING MAY SERIOUSLY DAMAGE THE VEHICLE OR EVEN
CAUSE A FIRE.
CAUTION
DRINKING WATER CONTAINS MINERALS THAT CAN BE EXTREMELY HARMFUL TO THE BAT-
TERY: USE DISTILLED WATER ONLY.
CAUTION
TO ENSURE MAXIMUM PERFORMANCE THE BATTERY MUST BE CHARGED BEFORE USE.
INADEQUATE CHARGING OF THE BATTERY WITH A LOW ELECTROLYTE LEVEL BEFORE IT
IS FIRST USED SHORTENS THE LIFE OF THE BATTERY.
Checking the electrolyte level
The electrolyte level must be checked frequently and must reach the upper level. Only use distilled
water, to restore this level. If it is necessary to add water too frequently, check the vehicle's electrical
system: the battery works overcharged and is subject to quick wear.
- Remove the short closed tube and the caps, then
pour sulphuric acid into the cells using the type
specified for batteries with a specific gravity of
1.26, corresponding to 30 Bé at a minimum tem-
perature of 15°C until the upper level is reached.
- Allow to stand for at least 2 hours, then top up the
level with sulphuric acid.
- Within the following 24 hours, recharge with the
specific (single) or (multiple) battery charger at an
intensity approx. to 1/10 of the battery rated ca-
pacity and until the acid density is approximately
1.27, corresponding to 31º Bé, and these values
are stabilised.
- After charging, level the acid (adding distilled
water). Close and clean carefully.
- Once the above operations have been per-
formed, install the battery in the vehicle ensuring
that it is wired up properly.
