(size 17 mm) by turning in anticlockwise direction.
– Insert the clamping shaft of the grinding tool to the stop in-
to the collet chuck
1
.
– Tighten the clamping nut
2
with the open-end spanner
9
(size 17 mm) by turning in clockwise direction.
The grinding tools must run completely concentrical. Do not
continue to use out-of-round grinding accessories, instead,
replace before continuing to work.
f
Do not tighten the collet chuck of the clamping nut as
long as no grinding accessory is mounted.
Otherwise,
the collet chuck can become damaged.

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. 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-
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
materials to be worked.
f
Prevent dust accumulation at the workplace.
Dusts can
easily ignite.
Operation
Starting Operation
f
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.
f
Visually check the collet chuck 1 and the clamping nut
2 are free from cracks or defects before use.
Switching On and Off
To
start
the power tool, push the On/Off switch
5
forwards.
To
lock
the On/Off switch
5
, press the On/Off switch
5
down
at the front until it latches.
To
switch off
the power tool, release the On/Off switch
5
or,
if it is locked, briefly push down the back of the On/Off switch
5
and then release it.
Working Advice
Optimum grinding results are achieved when the grinding tool
is moved uniformly back and forth with light pressure. Pres-
sure that is too strong reduces the performance capability of
the machine and causes the grinding tool to wear more quick-
ly.
Maintenance and Service
Maintenance and Cleaning
f
Before any work on the machine itself, pull the mains
plug.
f
For safe and proper working, always keep the machine
and ventilation slots clean.
f
In extreme conditions, always use dust extraction as
far as possible. Blow out ventilation slots frequently
and install a residual current device (RCD).
When work-
ing metals, conductive dust can settle in the interior of the
power tool. The total insulation of the power tool can be im-
paired.
Please store and handle the accessory(-ies) carefully.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.
In all correspondence and spare parts order, please always in-
clude the 10-digit article number given on the type plate of
the machine.
