Removing the Drill Chuck (see figure D)
Clamp the short end of an Allen key 15 into the
keyless chuck 1.
Place the machine on a stable surface (e. g. a
workbench). Hold the machine firmly and loos-
en the keyless chuck 1 by turning the Allen key
15 in rotation direction . Loosen a tight-seated
keyless chuck by giving the long end of the Allen
key 15 a light blow. Remove the Allen key from
the keyless chuck and completely unscrew the
keyless chuck.
Mounting the Drill Chuck (see figure E)
The keyless chuck is mounted in reverse order.
The drill chuck must be tightened with
a tightening torque of approx.
10–25 Nm.
Screw the securing screw 14 in anti-clockwise
direction into the opened keyless chuck, tight-
ening torque approx. 1.5–2.5 Nm. Always use a
new securing screw, as the threads are covered
with a thread-locking compound that loses its
effect after multiple usage.
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 10 to the cen-
tre position to protect the power tool against
accidental starting.
Insert the charged battery 8 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 F)
The rotational direction switch 10 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 11 actuated.
Right Rotation: For drilling and driving in
screws, push the rotational direction switch 10
left to the stop.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 10 through to the right stop.
Setting the Torque
With the torque presetting ring 2 the required
torque setting can be preselected in
25+1 steps. With the correct setting, the insert
tool is stopped as soon as the screw is screwed
flush into the material or when the adjusted
torque is reached. The safety clutch is deactivat-
ed in the " " position, e. g. for drilling.
Select a higher setting or switch to the
" " symbol when unscrewing screws.
Setting range 1–20:
Lower torque for screwing in screws with small
diameter or into soft materials. Fine torque gra-
dients between the individual setting positions.
