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 con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials contain-
ing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class
respirator.
Observe the relevant regulations in your coun-
try for the materials to be worked.
Operation

Starting Operation

Inserting the Battery
Use only original Bosch lithium ion batteries
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 9 to the centre
position in order to avoid unintentional starting.
Insert the charged battery 6 into the handle so
that it can be felt to engage and faces flush
against the handle.
Reversing the Rotational Direction
(see figure F)
The rotational direction switch 9 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 10 actuated.
Right Rotation: For drilling and driving in screws,
push the rotational direction switch 9 left to the
stop.
2 609 002 498 | (7.1.08)
The indicator for right rotation 4 lights up
when the On/Off switch 10 is actuated
and the motor is running.
Left Rotation: For loosening or unscrewing
screws, push the rotational direction switch 9
right to the stop.
The indicator for left rotation 5 lights up
when the On/Off switch 10 is actuated
and the motor is running.
Setting the Torque
The required torque can be preselected in 10+1
steps with the torque preselection ring 3. 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".
Drilling
The safety clutch is deactivated in the "Drilling"
position.
Switching On and Off
To start the machine, press the On/Off switch 10
and keep it depressed.
The power light 7 lights up when the On/Off
switch 10 is slightly depressed, and enables illu-
mination of the screwing location in unfavourable
light conditions.
To switch off the machine, release the On/Off
switch 10.
Adjusting the Speed
The speed of the switched on power tool can be
variably adjusted, depending on how far the
On/Off switch 10 is pressed.
Light pressure on the On/Off switch 10 results in
a low rotational speed. Further pressure on the
switch results in an increase in speed.
Fully automatic spindle locking (Auto-lock)
When the On/Off switch 10 is not pressed, the
drill spindle and thus the tool holder are locked.
This enables screws to be screwed in, even when
the battery is empty and allows for the machine
to be used as a screwdriver.
