Checking the level of electrolyte solution in
the batteries
Place the batteries on a level surface, then proceed as follows.
 Visually check that the fluid level is between the "Min" and "Max" lim-
its; in the absence of references, check that the fluid covers the Lead
plates inside the elements by approximately 5 mm.
 If necessary, top up with distilled water only those elements in
which the level is below minimum.
 On this occasion, make sure that the terminals and clamps are
clean, properly locked and protected by vaseline.
Some types of battery have a single cover for all the inspection plugs.
To access the elements, use a lever as shown in the figure.
Cleaning the air filters
Proceed with the engine stopped.
 Loosen the clamps holding the two filters (1, figure on the next page).
 Remove the filters from their housing.
 Blow dehumidified compressed air through the filter element, from
the inside outward (maximum pressure 200 kPa), or wash with wa-
ter only. Do not use detergents; do not use diesel.
 If the filters are damaged, replace them.
 Replace the filters at least once every 2 years.
 Return them to their proper position and lock the retaining clamps.
WARNING
Contact specialised technical staff if all the elements in the battery
need topping up with a considerable amount of distilled water, and
have them diagnose the efficiency of the batteries and the recharging
system.

CAUTION!
 The batteries contain sulphuric acid, which is extremely
caustic and corrosive; always wear protective gloves and gog-
gles when topping them up. Whenever possible it is recom-
mended that this control be carried out by specialised
personnel.
 Do not smoke or use live flames near the batteries during
controls, and make sure that the room you are working in is
adequately ventilated.
