ENGLISH
Removing and refitting the chuck (fig. C)
Open the chuck as far as possible.

Remove the chuck retaining screw by turning it clockwise

using a screwdriver.
Tighten an Allen key (14) into the chuck and strike it with

a hammer as shown.
Remove the Allen key.

Remove the chuck by turning it counterclockwise.

To refit the chuck, screw it onto the spindle and secure it

with the chuck retaining screw.
Use
Warning! Let the tool work at its own pace. Do not overload.
Charging the battery
The battery needs to be charged before first use and whenever
it fails to produce sufficient power on jobs that were easily
done before. When charging the battery for the first time, or
after prolonged storage, it will only accept an 80% charge.
After several charge and discharge cycles, the battery will
attain full capacity. The battery may become warm while
charging; this is normal and does not indicate a problem.
Warning! Do not charge the battery at ambient temperatures
below 4 °C or above 40 °C. Recommended charging
temperature: approx. 24 °C.
Charger with charging base (fig. D)
To charge the battery (5), remove it from the tool and

insert it into the charging base (8). The battery will only fit
into the charging base in one way. Do not force. Be sure
that the battery is fully seated in the charging base.
Plug in the charger.

After normal use, a charging time of 3 hours will provide
sufficient power for most applications. However, further
charging for up to 6 hours could significantly increase the use
time, depending on the battery and charging conditions.
Remove the battery from the charger.

Charger without charging base (fig. E)
To charge the battery, make sure that it is fitted on the drill.

Insert the charger plug (10) into the connector (9).

Plug in the charger.

Switch on at the mains.

After normal use, a charging time of 3 hours will provide
sufficient power for most applications. However, further
charging for up to 6 hours could significantly increase the use
time, depending on the battery and charging conditions.
Disconnect the tool from the charger.

Warning! Do not use the tool while it is connected to the
charger.

Selecting the direction of rotation
For drilling and for tightening screws, use forward (clockwise)
rotation. For loosening screws or removing a jammed drill bit,
use reverse (counterclockwise) rotation.
To select forward rotation, push the forward/reverse slider

(2) to the left.
To select reverse rotation, push the forward/reverse slider

to the right.
To lock the tool, set the forward/reverse slider into the

centre position.
Selecting the operating mode or torque (fig. F)
This tool is fitted with a collar to select the operating mode and
to set the torque for tightening screws. Large screws and hard
workpiece materials require a higher torque setting than small
screws and soft workpiece materials. The collar has a wide
range of settings to suit your application.
For drilling in wood, metal and plastics, set the collar (3) to

the drilling position by aligning the symbol with the
marking (15).
For screwdriving, set the collar to the desired setting. If you

do not yet know the appropriate setting, proceed as follows:
- Set the collar (3) to the lowest torque setting.
- Tighten the first screw.
- If the clutch ratchets before the desired result is
achieved, increase the collar setting and continue
tightening the screw. Repeat until you reach the correct
setting. Use this setting for the remaining screws.
Switching on and off
Variable speed switch
To switch the tool on, press the variable speed switch (1).

The tool speed depends on how far you press the switch.
To switch the tool off, release the variable speed switch.

Two-speed on/off switch
To switch the tool on, press the on/off switch (1).

When slightly pressing the switch, the tool will run at low
speed. When pressing the switch further, the tool will run
at high speed.
To switch the tool off, release the variable speed switch.

Hints for optimum use
Drilling
Always apply a light pressure in a straight line with the drill bit.

Just before the drill tip breaks through the other side of the

workpiece, decrease pressure on the tool.
Use a block of wood to back up workpieces that may

splinter.
Use spade bits when drilling large diameter holes in wood.
