Switching on and off
Switching on:
To start the tool, press the On / Off switch
5
and keep it pressed (see Fig. K). LED work light
13
lights up when the On / Off switch
5
is
depressed lightly or fully. It illuminates the work
area in low lighting condition.
Switching off:
Release the On / Off switch
5
to switch off
the tool
Note:
LED work light
13
will keep on for about
10s right after tool is switched off (On / Off switch
5
is released)
Adjusting the rotational speed
The On / Off switch
5
has a variable speed con-
trol function. By pressing it lightly yields a low
speed. Increase pressure increases the speed
(see Fig. K).
Note:
The integrated motor brake ensures rapid
stoppage.
Changing the rotational
direction
Change the direction of rotation by pressing
the rotational direction switch
4
toward the
left or right (see Fig. L).
When the rotary direction switch
4
is in the
middle position, the on / off switch is locked.
Tips and tricks
Tip! This symbol indicates
proper behaviour!
Before operation, check whether the screw or
drill bit is correctly positioned, i.e. centred in
the drill chuck.
Screw bits are labelled according to their
dimensions and their shape. If you are uncer-
tain, always check whether the bit fits tightly in
the screw head without any free play.
Torque:
Smaller screws / bits can be damaged if you
set the torque or rotational speed too high.
Hard screw joints (in metal):
Particularly high torques occur, for example, in
metal screw joints made using drive sockets.
Select a low rotational speed.
Soft screw joints (e.g. in soft wood):
Again, use a low rotational speed, to avoid
e.g. damaging the surface of the wood upon
contact with the screw head. Use a countersink.
When drilling in wood, metal and other
materials, observe the following:
Use a high speed for drill bits with small diame-
ter and a low speed for drill bits with large di-
ameter.
Select a low speed for hard materials and a
high speed for soft materials.
Secure or fasten the workpiece in a clamp or
vice (if possible).
Mark the spot where you want to drill using a
centre punch or nail. Select a low rotational
speed when starting.
Pull the rotating drill bit from the hole
repeatedly to remove dust and chips and clear
the hole.
Drilling in metal:
Use a metal drill (HSS). For optimum results,
cool the drill bit with cutting oil. Metal drill bits
can also be used to drill into plastics. Start with
a 3 mm diameter drill bit and then increase the
size until the desired hole diameter is achieved.
