between 1.26 kg/lt (30° Bè) and 1.20 kg/lt (24° Bè)
the battery is not fully charged, while if the density
is lower that 1.14 kg/lt (18° Bè) the battery is
completely flat.
The measurement of the electrolyte density is the
most import check made on a battery. Therefore, it
must be made with the utmost attention with a
densimeter. Insert the syringe densimeter and take
just enough electrolyte to bring the float to the
surface. Make sure that the top of it does not touch
the rubber pear or that it does not remain stuck with
capillarity to the glass sides. Measure the density
after adding distilled water and wait for the density
to become homogeneous throughout the liquid
contained in the element.
-
Add distilled water to every single cell of the battery
after having loaded the batteries to bring the level
of the water 6 mm above the plates. At the beginning,
this operation will have to be repeated after every
charge, but from then on it can be done less
frequently, according to the supervisor’s experience,
but never going over a week between one
replenishment and the next.
-
It is not necessary to recharge the battery if, at the
end of a day of work, the density has not gone
below 1.24 kg/lt (28° Bè).
The most common misuse found in batteries for
traction is overcharging. This factor on its own, if
done continuously, can drastically shorten the life
of the batteries. The maximum recommended
temperature is 45°C, if the temperature of the
electrolyte increases by over 10/12°C compared to
the environmental temperature, overcharging can
come about independently from the actual
temperature reached.
-
The gases that develop during the recharging
operation can cause explosions, therefore the battery
has to be in a well-ventilated place during the
recharging operation and the contacts with the
terminals have to be safe so that sparks are not
created. The rooms in which the batteries are
recharged haveto be well-ventilated and the
temperature must not exceed 40/45°C. If there is
not enough aeration through the windows special
discharge flues must be provided, but they must
not lead off into chimneys.
When it is necessary, the change of air must be
made more rapid with the use of ventilators.

The batteries discharge spontaneously (self-
discharge) during periods of inactivity. With this self-
discharge the battery loses a part of its charge every
day and also causes sulphation of the plates which
increases in time, to the detriment of the efficiency
of the battery. If the battery is not used continually,
it has to be re-charged at least once a month. In
any case, before putting a battery back into use
after it has been inactive for a long time, it has to
be recharged.
The squeegee blades have to be replaced when
the contact edge is abraded; in fact the integrity
and perfection of the edge is essential for perfect
drying. To replace the blades, the squeegee has
to be disassembled. Bring the squeegee support to
the high position, remove the suction tube from the
squeegee and remove the knobs. Now it is possible
to remove the squeegee from the machine and
place it on a bench. Unscrew the knobs and remove
plastic support. Carry out the same procedure on
the contrary to assemble the new blades, then
adjust the squeegee.
