PREPARING THE BATTERY
(EXCEPT MAINTENANCE-FREE BATTERIES)
Regarding use of electrolyte, please read this manual carefully and fill the electrolyte liquid correctly, making sure
not to spill any.
WARNING:
Check to make sure the electrolyte is the same type as in the battery.
The electrolyte must always be filled with the battery removed from the machine.
The fitting of bolts and nuts must be carried out after filling with electrolyte.
PREPARING THE BATTERY:
Place the battery on a flat surface and remove the filling orifice seal.
PREPARING THE ELECTROLYTE:
Remove the electrolyte container from the PVC wrapping and remove the top cover by sliding sideways.
FILLING THE BATTERY WITH ELECTROLYTE:
Fit the electrolyte container vertically into the battery filling orifice and push in with a single movement. This will
cause the seal to break and allow the liquid filling to begin.
N.B.: The electrolyte container needs to be correctly inserted, otherwise the battery may fall over or the sul-
phuric acid may spill out
PLEASE CHECK THE FOLLOWING:
That bubbles are emerging from the 6 reservoirs.
That the liquid level is falling gradually.
Allow to stand for 10 minutes (no more than 12 hours)
N.B.: If there are places where no bubbles are emerging, the liquid can be encouraged to enter by tapping this
part with the finger without removing the electrolyte container.
REMOVING THE ELECTROLYTE CONTAINER:
Check once again that no electrolyte is remaining. If there is electrolyte remaining, tap the container gently.
Remove the electrolyte container carefully.
Clean off any electrolyte that may have splashed onto the battery.
FITTING THE HERMETIC PLUG:
Remove the hermetic plug fitted to the battery and position it gently horizontally lined up with the liquid filling
orifice.
Push down several times with both hands on the 6 parts until it is at the same level as the top of the battery.
N.B.: Do not adopt the method of pushing each hermetic plug once.
PRECAUTIONS FOR HANDLING:
Take care that the electrolyte does not come into contact with the skin or eyes when filling the battery.
In the event of electrolyte coming into contact with clothing or skin, the affected part must be washed immedia-
tely with plenty of water and then washed with soap and water.
In the event of electrolyte coming into contact with the eyes, the effected eye must be washed immediately with
running water and the nearest medical personnel contacted.
Before disposing of the container, it should be made safe by diluting the contents in water or neutralising it and
then washing the contents with water.
Sulphuric acid: 41%
Specific weight: 1.32
