Rotating the Machine Head
Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
machine head carefully, without removing it from the hous-
ing, to the new position. Screw in and tighten the four screws
again.
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-
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
Inserting the battery
Insert the charged battery 5 from the front into the base of the
power tool until the battery is securely locked.
Switching On and Off
To start the power tool, push the On/Off switch 3 forwards.
To lock the On/Off switch 3, press the On/Off switch 3 down
at the front until it latches.
To switch off the power tool, release the On/Off switch 3 or,
if it is locked, briefly push down the back of the On/Off switch
3 and then release it.
To save energy, only switch the power tool on when using it.
Bosch Power Tools
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.
The machine head can be

Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
Do not use the power tool with a cut-off stand.
When the power tool is electrostatically charged, the built-in
electronic control switches it off. To restart the power tool,
press the On/Off switch 3 again.
Rough Grinding
Never use a cutting disc for roughing.
The best roughing results are achieved when setting the ma-
chine at an angle of 30° to 40°. Move the machine back and
forth with moderate pressure. In this manner, the workpiece
will not become too hot, does not discolour and no grooves
are formed.
Flap Disc
With the flap disc (accessory), curved surfaces and profiles
can be worked.
Flap discs have a considerably higher service life, lower noise
levels and lower sanding temperatures than conventional
sanding sheets.
Cutting Metal
For cutting with bonded abrasives, always use the pro-
tection guard for cutting 16.
When cutting, work with moderate feed, adapted to the mate-
rial being cut. Do not exert pressure onto the cutting disc, tilt
or oscillate the machine.
Do not reduce the speed of running down cutting discs by ap-
plying sideward pressure.
