Safety Information
Battery chargers
Use only SRC/ SRU Atlas Copco battery charger
(see optional accessories). Please see separate in-
structions delivered with the charger.
Battery Packs
Fully charge new or long time unused battery
packs before using your battery machine. Full
loading capacity of battery pack is reached af-
ter 4 – 5 chargings.
The contact points of chargers and battery packs
must be kept clean.
If the machine will not be used for 100 hours or
longer: separate the battery from the machine. Oth-
erwise the electronics will discharge the battery.
Battery Pack Reception
Put the battery pack in the battery machine so that
the clamps are secured. The battery can be placed
in two alternative positions, pointing forward or
backward, for best accessibility and balance. Re-
moval of Battery Pack: Press down the button,
then take out the battery pack of the battery ma-
chine.
Since a battery discharge itself slowly, it should re-
main in the charging unit which provides a trickle
charge.
Signal lights
The green LED indicates an OK tightening, i. e.
the machine has been shut off by the clutch. When
the battery energy is not sufficient for any more
correct tightening, the motor will be shut off and
the red LED will blink at a high frequency.
Theft protection (only – PROT
version)
The theft protection system disables the machine
from unauthorized use.
After connecting the battery to the machine : the
IR-sensor, situated between the green and red
LEDs, has to be moved over the 'eye' of the de-
coder until an acoustic signal indicates that the ma-
chine is unlocked. Install the decoder theft-proof.
