FEIN mechanics.
Modern and reliable mechanics integrated in
outstanding ergonomics – that is the concept
of the A
CCU
T
EC
shut-off screwdriver. By em-
ploying brushless EC motor technology in
theA
CCU
T
EC
ASM and ASW screwdrivers, ser-
vice life is highly increased compared to con-
ventional motors. Premature motor replace-
ment is eliminated. Follow-up costs in main-
tenance and spare parts are kept to
a mimum.
Low Energy Lock.
The new A
CCU
T
EC
screw guns with the pistol
grip also features Low Energy Lock.
A restart lock monitors the remaining charge
of the battery. Before the charge becomes too
low to provide the desired torque the ma-
chine is locked. Fastening is not possible until
the battery has been exchanged. The switch-
on delay blocks the machine for 0.8 seconds,
which avoids undesired retightening of the
fastener. This function is activated immediate-
ly after the switch is released.
Loaded with extras.
An LED indicator lights up when the preset
torque has been reached. Improper fastenings
are indicated by the red LED and an acoustical
signal. Battery capacity is monitored continu-
ously. The LED indicator also signals when the
battery should be exchanged.
