Dust/Chip Extraction

Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation

Starting Operation

Inserting the battery
Note: The use of batteries unsuitable for your power tool can
lead to malfunctions or damage to the power tool.
Set the rotational direction switch (7) to the middle position
to avoid unintentionally switching it on. Insert the charged
battery (6) into the handle until you feel it engage and it is
flush with the handle.
Setting the rotational direction (see figure B)
The rotational direction switch (7) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (8) is being pressed.
Right rotation: To drill and to drive in screws, press the ro-
tational direction switch (7) through to the left stop.
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (7) through to the right
stop.
Switching on/off
To start the power tool, press and hold the on/off switch
(8).
To switch off the power tool, release the on/off switch (8).
Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (8) to varying extents.
A light pressure on the on/off switch (8) results in a low rota-
tional speed. Increased pressure on the switch causes an in-
crease in speed.
Preselecting the torque
The torque presetting ring (3) can be used to preselect the
required torque in 20 stages and "MAX". Once the set torque
has been reached, the application tool will be stopped.
For drilling use the "MAX" setting.
Bosch Power Tools
Mechanical Gear Selection
You can press the gear selector switch (4) with the
u
power tool off or on. You should not do this at full load
or maximum torque, however.
Gear I:
Low speed range; for working with a large drilling diameter
or for screwdriving.
Gear II:
High speed range; for working with a small drilling diameter.
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or the permitted bat-
tery temperature is exceeded, the electronics of the power
tool will switch off until the temperature returns to within the
optimum operating temperature range.
Protection against deep discharge
The lithium-ion battery is protected against deep discharge
by the Electronic Cell Protection (ECP). When the battery is
discharged, the power tool is switched off by means of a pro-
tective circuit: The application tool no longer rotates.
Practical advice
Only apply the power tool to the screw/nut when the
u
tool is switched off. Rotating tool inserts can slip off.
After working at a low speed for an extended period, you
should operate the power tool at the maximum speed for ap-
proximately three minutes without load to cool it down.

Maintenance and Servicing

Maintenance and Cleaning

Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
