Auxiliary Handle; Dust/Chip Extraction - Bosch UniversalHammer 18V Originalbetriebsanleitung

Assembly
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.

Auxiliary handle

Make sure that the auxiliary handle is always
u
tightened. Otherwise you could lose control of the power
tool when working.
Swivelling the auxiliary handle (see figure A)
You can swivel the auxiliary handle (15) to any angle for a
safe work posture that minimises fatigue.
– Loosen the wing bolt (14) of the auxiliary handle (15)
and adjust the auxiliary handle (15) to the required posi-
tion. Then retighten the wing bolt (14) of the auxiliary
handle (15).
Make sure that the clamping ring of the auxiliary handle
slots into the corresponding groove on the housing.
Selecting drill chucks and tools
For hammer drilling and chiselling, you will need SDS plus
tools, which insert into the SDS plus drill chuck.
For drilling without impact in wood, metal, ceramic and
plastic as well as for screwdriving, tools without SDS plus
are used (e.g. cylindrical shank drill bits). A keyed chuck is
required for such drilling tools.
Note: Only use the keyed chuck in the drilling without im-
pact operating mode.
Changing the drill chuck
Inserting/removing the keyed chuck
You must use a suitable drill chuck (keyed or keyless chuck,
accessories) to work with tools that do not have SDS-plus
(e.g. cylindrical shank drill bits).
Inserting the keyed chuck (see figure B)
– Clean and lightly grease the insertion end of the shank
(18).
– Insert the keyed chuck (17) with the shank (18) into the
tool holder with a turning motion until it locks automatic-
ally.
– Check that it is locked by pulling the keyed chuck (17).
Changing the Tool
The dust protection cap (3) largely prevents the penetration
of drilling dust into the tool holder during operation. When
inserting the tool, make sure that the dust protection cap (3)
does not become damaged.
Replace a damaged dust protection cap immediately.
u
It is recommended that you have use an after-sales
service for this.

Changing the tool (SDS plus)
Inserting SDS-plus application tools (see figure C1)
The SDS-plus drill chuck enables you to change the applica-
tion tool easily and conveniently without needing to use ad-
ditional tools.
– Clean and lightly grease the insertion end of the applica-
tion tool.
– Insert the application tool into the tool holder while turn-
ing it until it locks automatically.
– Check the latching by pulling the tool.
As a requirement of the system, the SDS-plus application
tool can move freely. This causes a certain radial run-out at
no-load, which has no effect on the accuracy of the drill hole,
as the drill bit centres itself upon drilling.
Removing SDS-plus application tools (see figure C2)
– Push the locking sleeve (4) back and remove the applica-
tion tool.
Inserting screwdriver bits (see figure D)
Only apply the power tool to the screw/nut when the
u
tool is switched off. Rotating tool inserts can slip off.
A universal holder (19) with SDS-plus shank (accessory) is
required to work with screwdriver bits.
– Clean and lightly grease the insertion end of the shank.
– Insert the universal holder into the tool holder while turn-
ing it until it locks automatically.
– Check that it is locked by pulling the universal holder.
– Insert a screwdriver bit in the universal holder. Only use
screwdriver bits that fit the screw head.
– To remove the universal holder, slide the locking sleeve
(4) backwards and remove the universal holder (19)
from the tool holder.

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.
