Only use the battery charger in a dry environment at a temperature between 5 °C
and 40 °C.
The battery on the impact wrench you have purchased is not charged up. Before using it for the
first time leave it to charge for 1 - 2 hours in order for it to reach its full capacity. The total capacity
of the battery will be reached after it has been charged 4 – 5 times.
If the cordless impact wrench is not going to be used for a long period of time,
recharge the battery before storing. From time to time recharge the battery for a
short period of time, to prevent it from running down. Store the battery separately in
the plastic case.
Discharging the battery
Not only charging batteries is important, discharging is of equal importance or even
greater importance.
• When the battery is charged the cordless impact wrench has to be used until you start
noticing that the power of the drill is diminishing and that the maximum rotational speed is
not reached.
• The battery is almost discharged now. Only now you can start charging the battery.
• Charging the battery while it is still charged for say one-third of capacity, the so-called
‘memory effect’can occur. Since during charging only the discharged part of the battery
capacity of the battery is being charged now, the battery can start crystallizing in the one-
third that is still charged. This part of the battery capacity can never be used afterwards.
• Do not discharge the battery to the minimum. As soon as you notice that the power or the
maximum rotational speed is diminishing, you have to charge the battery. When you
proceed using the drill and the battery becomes fully discharged, the so-called ‘switch of
poles effect’can occur. The polarity of the battery poles will be switched: the ‘+’will become
‘-‘ and the ‘-‘ will become the ‘+’. Once this has occurred the polarity will remain switched
during loading and this will damage the battery irreparable.
When the impact wrench is not being used over a longer period of time,
the battery has to be charged fully first. The battery has to be stored in charged
condition.
5. SERVICE & MAINTENANCE
