Changing the Tool (see figure B)
Before any work on the machine (e. g.,
maintenance, tool change, etc.) as well as
during transport and storage, set the rota-
tional direction switch to the centre posi-
tion. Unintentional actuation of the On/Off
switch can lead to injuries.
The drill spindle is locked when the On/Off
switch 8 is not pressed. This makes quick, con-
venient and easy changing of the tool in the drill
chuck possible.
Open the keyless chuck 1 by turning in rotation
direction , until the tool can be inserted. Insert
the tool.
Firmly tighten the collar of the keyless chuck 1
by hand in rotation direction
action ("click") is no longer heard. This automat-
ically locks the chuck.
The locking is released again to remove the tool
when the collar is turned in the opposite direc-
tion.
Dust/Chip Extraction
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Bosch Power Tools

Operation
Starting Operation
Inserting the Battery
Use only original Bosch lithium ion batter-
ies with the voltage listed on the nameplate
of your power tool. Using other batteries can
lead to injuries and pose a fire hazard.
Set the rotational direction switch 7 to the cen-
tre position to protect the power tool against
accidental starting.
Insert the charged battery 6 from the front into
the base of the power tool. Push the battery
completely into the base until the red stripe can
no longer be seen and the battery is securely
locked.
Reversing the Rotational Direction
(see figure C)
The rotational direction switch 7 is used to re-
verse the rotational 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 7
left to the stop.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 7 through to the right stop.
Setting the Torque
The required torque can be preselected in 20
steps with the torque preselection ring 2. With
the correct setting, the insert tool is stopped as
soon as the screw is screwed flush into the ma-
terial or when the set torque is reached.
Select a higher setting when driving out screws,
or set to the symbol "Drilling".
Gear Selection, Mechanical
The gear selector 3 can be actuated at
standstill or when the machine is running.
However, this should not be done while op-
erating at full load or maximum speed.
Two speed ranges can be preselected with the
gear selector 3.
