Bosch GSB 162-2 RE Original Instructions Manual page 15

To remove the application tool, turn the eccentric cam in ro-
tational direction ➊ and open the keyed chuck (16) with the
chuck key (15).
Screwdriving Tools
You should always use a universal bit holder (14) when using
screwdriver bits (13). Only use screwdriver bits that fit the
screw head.
For screwdriving, make sure the "drilling/impact drilling" se-
lector switch (2) is always set to the "drilling" symbol.
Changing the drill chuck
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Removing the Drill Chuck (see figure F)
To remove the keyed chuck (1), place an open-ended span-
ner (17) (width across flats: 17 mm) onto the spanner flat of
the drive spindle.
Place the power tool on a firm surface, e.g. a work bench. In-
sert the chuck key (12) into one of the three holes of the
keyed chuck (1) and release the keyed chuck (1) with this
lever by turning it in rotational direction ➊. A keyed chuck
that is fixed in place can be released by applying light force
to the chuck key (12). Remove the chuck key (12) from the
keyed chuck and completely unscrew the keyed chuck.
Fitting the Drill Chuck (see figure G)
The keyed chuck is fitted in reverse order.
The drill chuck must be tightened using a tight-
ening torque of approx. 80–85 Nm.
Dust/Chip Extraction
Dust 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 dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (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 ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation
Starting Operation
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
Bosch Power Tools
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current

The rotational direction switch (3) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (5) is being pressed.
Clockwise rotation: To drill and drive in screws, slide the
rotational direction switch (3) to the left.
Anti-clockwise rotation: To loosen or unscrew screws and
