the set-collar (Figure 1). The cor-
rect torque depends on several
factors:
on the type and hardness of
material in question
on the type and length screws
used
on the requirements needing to
be met by the screwed joint.
The clutch disengages with a gra-
ting sound to indicate when the set
torque is reached.
Drilling
For drilling purposes, move the set-
collar to the last step „Drill" (Figure
1). In this setting the slip clutch is
inactive. The maximum torque is
available in drilling mode.
Changing over from 1st gear to
2nd gear (Figure 2)
You can work at a higher or lower
speed depending on the position of
the selector switch. To avoid dama-
ging the gear unit you should only
change over gears when the tool
has stopped.
Forward/Reverse switch (Figure
3)
With the slide switch above the
On/Off switch you can select the
direction of rotation of the battery-
12
powered drill/screwdriver and secu-
re it against being switched on
accidentally. You can choose bet-
ween clockwise and anticlockwise
rotation. To avoid causing damage
to the gearing it is advisable to
change the direction of rotation
only when the tool is at a standstill.
The On/Off switch is blocked when
the slide switch is in centre positi-
on.
On/Off switch (Figure 4)
Infinitely variable speed control is
possible with the On/Off switch.
The further you press the switch,
the higher the speed of the battery-
powered drill/screwdriver.
Screwdriving
We recommend using self-cente-
ring screws (e.g. Torx screws,
recessed head screws) designed
for reliable working. Be sure to use
a bit that matches the screw in
shape and size. Set the torque, as
described elsewhere in these ope-
rating instructions, to suit the size
of screw.
