BATTERIES
•
Keep the battery room open during the batteries recharge;
•
It is forbidden to use flames and/or to smoke near the batteries;
•
Pay attention to the battery acid;
•
Do not develop sparks near the batteries;
•
Pay attention to the batteries gazes, which can burst;
•
Do not invert battery polarities.
CHECKING THE BATTERY CHARGE
The operator has to check the batteries charge when the machine is on duty by means
of the indicator on the dashboard, which shows:
•
Green light: charged battery
•
Yellow light: slightly charged battery
•
Red light: uncharged battery
HYDROMETRY
In order to check the batteries hydrometry the operator has to follow the instructions
below:
1.
By means of a hydrometre draw a small quantity of electrolyte so that the floater
reaches the surface;
2.
Make sure that the floater inside the hydrometre is not blocked;
3.
For a new measurement, after having filled the batteries with distilled water, the
operator has to wait until the liquid inside each battery becomes homogeneous.
WATER FILLING UP
1.
Fill distilled water up in each battery cell before the recharge. The liquid inside the
batteries has to be of 6 mm. over the plates;
2.
The operator has to repeat the same operation every time the level decreases (every
week).
CHARGE LIMITS
It is not necessary to recharge the batteries if the hydrometry, after a work day, is not
under 1,24 (28 Bè). The highest suggested temperature is 45°C. If the electrolyte
