Screwdriver Tools
When working with screwdriver bits 5, a universal bit holder
11 should always be used. Use only screwdriver bits that fit
the screw head.
Replacing the Drill Chuck
For machines without spindle lock, the drill chuck must be re-
placed through an authorized after-sales service agent for
Bosch power tools.
The drill chuck must be tightened with a tightening
torque of approx. 35–40 Nm.
Dust/Chip Extraction
Dusts 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 dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (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
materials to be worked.
Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Operation
Starting Operation
Inserting the Battery
Use only original Bosch O-pack batteries with the volt-
age given on the type plate of your machine. The use of
other batteries can lead to injuries and danger of fire.
Set the rotational direction switch 9 to the centre position in
order to avoid unintentional starting. Insert the charged bat-
tery 7 into the handle so that it can be felt to engage and faces
flush against the handle.
Reversing the Rotational Direction (see figure B)
The rotational direction switch 9 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 8 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 9 left to the stop.
Left Rotation: For loosening or unscrewing screws, push the
rotational direction switch 9 right to the stop.
Setting the Torque
The required torque can be preselected in 5 steps with the
torque preselection ring 4. With the correct setting, the insert
tool is stopped as soon as the screw is screwed flush into the
material or when the set torque is reached.
Select a higher setting when driving out screws, or set to the
symbol "Drilling".

Switching On and Off
To start the machine, press the On/Off switch 8 and keep it
pressed.
To switch off the machine, release the On/Off switch 8.
Adjusting the Speed
The speed of the switched on power tool can be variably ad-
justed, depending on how far the On/Off switch 8 is pressed.
Light pressure on the On/Off switch 8 results in a low rotation-
al speed. Further pressure on the switch results in an increase
in speed.
Run-on Brake
When the On/Off switch 8 is released, the chuck brakes to a
stop, thus preventing the run-on of the tool.
When driving in screws, wait until the screw is screwed in
flush with the material and then release the On/Off switch 8.
By doing so, the head of the screw does not penetrate into the
material.
Working Advice
Apply the power tool to the screw only when it is
switched off. Rotating tool inserts can slip off.
After longer periods of working at low speed, allow the ma-
chine to cool down by running it for approx. 3 minutes at max-
imum speed with no load.
For drilling in metal, use only perfectly sharpened HSS drill
bits (HSS=high-speed steel). The appropriate quality is guar-
anteed by the Bosch accessories program.
Before screwing larger, longer screws into hard materials, it is
advisable to predrill a pilot hole with the core diameter of the
2
thread to approx.
/
of the screw length.

Maintenance and Service
Maintenance and Cleaning
Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
For safe and proper working, always keep the machine
and ventilation slots clean.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.
In all correspondence and spare parts order, please always in-
clude the 10-digit article number given on the type plate of
the machine.
