Mechanical 2-speed selector
For battery equipment, the mechanical 2-speed selec-
tor permits optimal drilling torques of 0–1600 rpm in
2nd speed and with high transmission in 1st speed
(0–470 rpm) very high tractive power even with
screws of a large diameter. The switchover is per-
formed by moving the switch 3 until it stops in position
1 or 2.
Torque selection
The battery-driven rotary screwdriver is equipped with
a seven-stage mechanical torque selection. The start-
ing torque for a particular screw is set at the adjusting
ring 4 according to the scale.
The volume of the torque is dependent on various fac-
tors – type and hardness of the material to be proc-
essed, type and length of the screws to be used, but
in addition the demands made on the screw connec-
tion. The data contained in the following table should
be observed as a guideline:
Stage 1 = approx. 1 Nm: screws Ø 3 mm
Stage 2 = approx. 2 Nm: screws Ø 3.5 mm
Stage 3 = approx. 3 Nm: screws Ø 4 mm
Stage 4 = approx. 4 Nm: screws Ø 4.5 mm
Stage 5 = approx. 5 Nm: screws Ø 5 mm
Stage 6 = approx. 6 Nm: screws Ø 5.5 mm
Stage 7 = approx. 7 Nm: screws Ø 6 mm
When the set torque is reached it is signalled acousti-
cally through the construction of the torque coupling.
The coupling disengages with a click.
Operation of the
Quick Clamping Drill Chuck
Rotational direction switch in the LOCK position
The fully automatic spindle locking makes possible
quick and easy changing of the tool in the drill chuck.
Opening:
Turn the sleeve in the "AUF" direction.
Clamping: Open the chuck and insert the tool as far
as possible.
Firmly clamp the chuck by turning the
sleeve in the "ZU" direction.
For soft drill shafts, it may be necessary to retighten
after a short time.
Caution! For reasons of safety, take the bat-
tery out of the device for all installation and
removal operations!

Practical Tips
Drilling
When drilling, set the torque ring to the "drill" symbol.
The torque coupling is deactivated. Maximum torque
is available for drilling.
When drilling steel, take care that no swarf
enters the ventilation slits of the housing, as
these are attracted by the permanently active
magnet of the motor and would remain on the
motor.
Screwing
Make sure that the bit and screw correspond in size
and shape.
It is advisable to use socket-head screws since their
self-centering action ensures safe work.
Or even better – TORX screws and the corresponding
bits. Optimal screwing is achieved when the screwing
device is fixed securely in the screw head.
Dismounting the Drill Chuck
Rotational direction switch in the LOCK position
Remove the left-hand threaded screw that secures
the drill chuck on the drill spindle against unscrewing
in left rotation. The drill chuck can then be loosened
by lightly striking a Allen key clamped in the drill chuck
and screwed off.
Remounting takes place in the reverse order.
Clean the flat surfaces on the drill chuck and spindle
before mounting. Screw on the drill chuck firmly and
secure with the safety screw.
Observe in addition that, when using a rim gear drill
chuck, the chuck key must not be attached to the
.
machine with chains, cords or similar means.
When drilling or screwdriving, secure the work
pieces against being rotated by the drill.
