Bosch Power Tools
Replacing the Drill Chuck
For machines without spindle lock, the drill
chuck must be replaced through an authorized
after-sales service agent for Bosch power tools.
The drill chuck must be tightened with a
tightening torque of approx. 25–30 Nm.
Dust/Chip Extraction
f
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.
f
Prevent dust accumulation at the work-
place.
Dusts can easily ignite.
Operation
Starting Operation
f
Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Reversing the Rotational Direction
f
Actuate the rotational direction switch 4
only when the machine is at a standstill.
The rotational direction switch
4
is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch
3
actuated.
Right Rotation:
For drilling and driving in
screws, push the rotational direction switch
4
left to the stop.
Left Rotation:
For loosening and unscrewing
screws and nuts, press the rotational direction
switch
4
through to the right stop.
Switching On and Off
To
start
the machine, press the On/Off switch
3
and keep it pressed.
To lock the
pressed
On/Off switch
3
, press the
lock-on button
2
.
To switch off the machine,
release
the On/Off
switch
3
.
Adjusting the Speed
The speed of the switched on power tool can be
variably adjusted, depending on how far the
On/Off switch
3
is pressed.
Light pressure on the On/Off switch
3
results in
a low rotational speed. Further pressure on the
switch results in an increase in speed.
Working Advice
f
Apply the power tool to the screw/nut only
when it is switched off.
Rotating tool inserts
can slip off.
Tips
After longer periods of working at low speed, al-
low the machine to cool down by running it for
approx. 3 minutes at maximum speed with no
load.
For drilling in metal, use only perfectly sharp-
ened HSS drill bits (HSS=high-speed steel). The
appropriate quality is guaranteed by the Bosch
accessories program.
