Assembly
Changing the Tool (see figure A)
Before any work on the machine itself, pull the mains
plug.
– Open the key type drill chuck 1 by turning until the tool can
be inserted. Insert the tool.
– Insert the chuck key 6 into the corresponding holes of the
key type drill chuck 1 and clamp the tool uniformly.
Screwdriver Tools (see figure B)
When working with screwdriver bits 7, a universal bit holder 8
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. 25–30 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-
1 609 92A 2DW | (27.7.16)
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 mate-
rials to be worked.
Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Operation
Starting Operation
Observe correct mains voltage! The voltage of the pow-
er 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
Actuate the rotational direction switch 4 only when the
machine is at a standstill.
The rotational direction switch 4 is used to reverse the rota-
tional 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 save energy, only switch the power tool on when using it.
– 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 ad-
justed, depending on how far the On/Off switch 3 is pressed.
Light pressure on the On/Off switch 3 results in a low rotation-
al speed. Further pressure on the switch results in an increase
in speed.
Working Advice
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, 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.
