Switching on and off
Switching on:
♦
To start the appliance, press the ON/OFF
switch and keep it pressed in .
The LED work light lights up when the ON/
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 to switch off the
appliance .
Adjusting the rotational speed
Press the ON/OFF switch lightly for a low
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 towards the left
or right .
Tips and tricks
Tip! This symbol indicates proper
behaviour.
♦
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 .
