Operation
Tips and notes on handling the cordless drill driver
General information:
•
Check the tool in the keyless drill chuck for correct fit
before every application. It must be firmly locked and
centred in the drill chuck.
•
Screw bits are marked with their size and shape. If you are
unsure, check whether the bit can be firmly tightened in
the keyless drill chuck without clearance.
•
The centre position of the clockwise/counter-clockwise
rotation switch (lock) is suited for work breaks or (drill) bit
exchange.
Screwing:
•
In case of soft wood, screws can be screwed in without
pre-drilling.
•
In case of hard wood or large screws, it is recommended
to use a drill for pre-drilling.
•
When using countersunk screws, the drill hole should be
countersunk beforehand.
•
Especially smaller screws and bits may be damaged when
selecting an excessive torque and / or speed at the tool.
Drilling in general:
•
Take short breaks regularly during drilling. When doing so,
take the drill bit out of the drill hole so that the drill bit can
cool down.
•
Secure the workpiece in a tensioning device or vice.
•
Select the speed depending on the material characteristics
and the size of the drill bit:
– High speed for small drilling diameter or soft material
– Low speed for large drilling diameter or hard material
•
Use a suitable aid to mark the intended location of the drill
hole.
•
Select a low speed for spudding.
Drilling in metal:
•
Use suitable metal drill bits (e.g. drill bits made of
high-speed steel
(HSS)).
•
For larger drilling diameters, use a smaller drill bit for
pre-drilling.
•
To achieve ideal results, the drill bit should be cooled with
a suitable lubricant.
•
Metal drill bits may also be used for drilling in plastic.
Drilling in wood:
•
Use drill bits suitable for wood.
•
Place a block of wood under the workpiece or drill in from
both sides so that the wood cannot break off when it is
being drilled through.
•
Use a wood drill bit with centring tip. For deep drill holes,
use an auger bit; for large drilling diameters, use a
Forstner bit.
Selecting the rotational direction
Note
Only change the rotational direction when the device is
at a standstill! Otherwise the device might be
damaged.
The motor's rotational direction can be changed by means of
the switch for clockwise/counter-clockwise rotation (5).
1. Press in the switch for clockwise/counter-clockwise
rotation (5) on the side to which the motor shall rotate.

2. Carry out a short test run to see whether the rotational
direction matches the intended application. A wrong
rotational direction may damage the tool and / or
workpiece.
3. If required, set the switch for clockwise / counter-
clockwise rotation (5) to centre position (lock) to block the
on/off switch (14).
