UK - GENERAL INFORMATIONS ABOUT
CHARGER-STARTERS THOR 320
1 ) The charger starter is a device capable to deliver high current for short period of time. Therefore, you must never insist
too much on the starting because these are risks to damage either the engine starter either the charger - starter
itself.
Every charger starter indicates always the maximum current which is able to deliver consequently when you choose
a charger starter you must verify that the maximum starting current corresponds to the starting current of the battery.
For example if the battery fitted into the vehicle is an 88Ah battery its starting current (if it is not already indicated) is
included in a range between 3 and 3,5 times its nominal capacity, it means between 260A and 310 Ampere.
To help start a vehicle it is necessary to have a charger starter capable to deliver similar current values.
2) When you effect starting it is always necessary to leave the battery connected.
3) You must never reverse polarity, in case of doubts, remember that the positive battery terminal is bigger than the
negative one and the negative battery terminal is connected to the vehicle's body.
4) The starting must not exceed 5 seconds and you must respect the starting cycles which are indicated on the
apparatus.
5) The charging current of the battery must Ce included between 1/10 and 1/5 of its capacity.
6) n case it is necessary to extend the cables; you can extend the primary cable by using a cable having the same
section of the primary cable.
7) The connecting clamps and the battery terminals must always be clean like also the battery surface.
8) The charger starters of this series have a decreasing charging characteristic, but you must be careful also when the
battery has been, charged because they continue to deliver current.
9) Before charging the battery, remove its caps and verify that the electrolytic liquid covers the metal plates for at least
4-5 mm. In Case of electrolytic liquid's lack; add distilled water.
10) If the battery is often run-downed, verify if the belt connected to the alternator is tightened and it delivers the right
current.
