tection guard 11.

Quick-clamping Nut (GGS 6 S)
(see figure C)
For convenient changing of grinding tools without the use of
additional tools, you can use the quick-clamping nut 8 instead
of the clamping nut 1.
f
Quick-clamping nut 8 may not be used for brushing.
Use only a flawless, undamaged quick-clamping nut 8.
When screwing on, pay attention that the side of the
quick-clamping nut 8 with printing does not face the
grinding disc; the arrow must point to the index mark 17.
A properly attached, undamaged quick-clamping nut can be
loosened by hand when turning the knurled ring in anticlock-
wise direction. Never loosen a tight quick-clamping nut
with pliers. Always use the two-pin spanner 16.
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.
Switching On and Off
To start the power tool, firstly push the safety switch against
starting 7 toward the front and afterwards press and hold the
On/Off switch 6.
To lock the pressed On/Off switch 6, push the lock-on button
7 further toward the front.
To switch off the power tool, release the On/Off switch 6, or
when it is locked, briefly press the On/Off switch 6 and then
release it.
f
Check grinding tools before using. The grinding tool
must be mounted properly and be able to move freely.
Carry out a test run for at least one minute with no load.
Do not use damaged, out-of-centre or vibrating grind-
ing tools. Damaged grinding tools can burst and cause in-
juries.
When not using the power tool, switch it off in order to save
energy.
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.
