Commissioning

5.1

Changing the battery pack

Removing the battery pack
Press and hold the two buttons [2-2].
Slide the battery pack forwards to remove.
Inserting the battery pack
Slide the battery pack onto the retainer on the
underside of the handle shown in Fig. [3] until it
engages.
5.2

Charging the battery pack

► The battery pack is delivered partially charged.
Charge the battery pack completely before using
for the fi rst time.
To charge the battery pack, slide all the way onto
the retainer [2-1] on the charger.
► To remove, slide the charged battery pack from
the charger in similar fashion.
The charger automatically detects the type of the
inserted battery (NiCd, NiMH or LiIon).
A microprocessor controls the charging process in
line with the charging state, temperature and volt-
age of the battery pack. If a warm NiMH battery
pack (> 37 °C) is inserted, the pack is charged with
a reduced charging current and will take longer to
charge.
The LED [3-1] on the charger indicates the respec-
tive operating status of the charger.
LED yellow – lit continuously
Charger is ready to use.
LED green – fl ashing quickly
Battery pack is charged to maximum capacity.
LED green – fl ashing slowly
Battery pack is charged with reduced current, LiIon
is charged to 80 %.
LED green – lit continuously
Battery pack is fully charged, conservation charg-
ing active.
LED red – lit continuously
Battery temperature is outside the permitted
range.
LED red – fl ashing
General fault display, e.g. incomplete contact, short
circuit, battery pack faulty, etc..
5.3 Wall mounting
There are two elongated holes on the back of the
BC 3 for mounting the charger to a wall using two
screws (e.g. round head or fl at head screw with
shank diameter of 5 mm).
Insert the two screws into the wall at a distance
of 96 mm from one another and leave the screw
heads protruding approx. 4 mm.

6 Machine settings
► Setting must be done only when the machine
is turned off and will be accepted only after
restarting it.
6.1 Changing the direction of
rotation
The right/left switch [1-3] changes the direction
of rotation.
Move switch from right to left = clockwise rotation;
Move switch from left to right = anticlockwise
rotation.
6.2

Changing gear

► Always switch off the machine before changing
gear!
You can change gear using the gear switch [1-4].

Fastening

Move the switch [1-6] to the torque setting [1-5].
Setting on 1
Setting on 12
The machine switches off when the preset torque
is reached and an acoustic signal sounds. You must
release and press the ON/OFF switch [1-2] again
to start the machine.
Upon levels 1 – 12, a decreased number of rota-
tions can be set.
6.4

Drilling

The selector switch [1-6] is set to the drill symbol
marking [1-5] = maximum torque.
6.5

Screw fastening and loosening

► Only place the machine on the nut/screw when
switched off.
The torque is dependent on the impact duration.
The maximum torque results from all the individual
torques which have been produced by impacts.
The maximum torque is obtained after an impact
duration of 6 to 10 seconds. After this time the
tightening torque only increases at a very low rate,
although the head does heat up noticeably.
Excessive heating causes all the components in the
impact mechanism to wear out more rapidly and
increases the lubrication requirement.
► The impact duration must be ascertained for
each required tightening torque. The tightening
torque which is actually obtained must always
be checked with a torque wrench.
► Two characteric types of joints for application:
Hard joints:
Bolted joint of two or more usually metal parts
which are not resilient during tightening nor are
they deformed by the applied tightening pres-
sure.
