Switching on and off
Switching on:
♦
To start the appliance, press the ON/OFF
switch
and keep it pressed in.
The LED work light
OFF switch
is depressed lightly or fully. This
allows for illumination of the work area in low
lighting.
Switching off:
♦
Release the ON/OFF switch
appliance.
Adjusting the rotational speed
Press the ON/OFF switch
speed. Increasing the pressure increases the speed.
NOTE
►
The integrated motor brake ensures rapid
stoppage.
Changing the direction of rotation
♦
Change the direction of rotation by pressing the
rotational direction switch
or right.
Tips and tricks
Tip! This symbol indicates proper
baviour.
♦
Before operating the appliance, check whether
the screw or drill bit is correctly positioned, i.e.
centred in the drill chuck.
♦
Screw bits are labelled according to their di-
mensions and their shape. If you are uncertain,
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, for example
to avoid damaging the surface of the wood on
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 dia-
meter and a low speed for drill bits with large
diameter.
♦
Select a low speed for hard materials and a
high speed for soft materials.
♦
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,
you should cool the drill bit with 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.
Drilling in brick:
♦
Use a carbide-tipped masonry drill.
(max. recommended hole diameter: Ø 15 mm)
Drilling in wood:
♦
Use a wood drill with a lathe centre; for deep
holes, use an auger bit; for large-diameter
holes, use a Forstner bit. Small screws can be
screwed directly into soft wood.
