6 - CHECK THE LEVEL OF THE BATTERY ELECTROLYTE
Check the level of the electrolyte in each battery cell “1” (fig.
B6/1).
If necessary, add only distilled water to restore the level.
Never add sulphuric acid.
If frequent topping up with distilled water becomes necessary,
or if the battery is subject to getting discharged, check the
regulator voltage, which must be between 13 V and 14,7 V,
with the engine running at maximum speed.
Once in a while, check the connecting terminals to make sure
they are not rusted.
If the vehicle is to remain unused for a long time, disconnect the battery.
When the ambient temperature is high, the level should be
checked more frequently than once every 50 hours.
Maintenance :
- Check connections “2” (fig. B6/2).
- Check eleclrolyte levels regularly “3” (fig. B6/2).
Add distilled or demineralised water if necessary.
- Never add acid.
- Battery needs to be recharged if voltage drops below 12.3 V
(specific gravity of 1.21).
- If vehicle is not being used for a long period, disconnect the
battery.
F. Charging (off the vehicle) :
- Remove vents “3” (fig. B6/2).
- Only use direct current (DC).
- Connecl “+” wìth “+”, “-” wìth “-”.
- Charge at recommended bench rate i.e. 10% of battery capacity.
- The battery is fully charged when specific gravìty has reached 1.28 (1.23 under tropical climate).
- When charge has completed.
- Switch off charger then disconnect.
- Check electrolyte level.

7 - DRAIN THE FUEL PREFILTER CARTRIDGE WITH WATER SEPARATOR (if necessary)
Place the truck on a flat surface with the
engine off.
Open the engine bonnet.
Visually check for the presence of water in
tank “1” (fig. B7) and drain if necessary.
Place a receptacle under the tank and loosen
drain plug “2” (fig. B7) by two of three turns.
Leave the diesel fuel to flow out until it is free
from impurities and water.
Tighten the drain plug while the diesel fuel is
running out.
