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.
The machine head can be
rotated with respect to
the machine housing in
90° steps. In this man-
ner, the On/Off switch
can be brought into a
more convenient position
for special working situa-
tions, e.g. for left-handed
persons.
Completely unscrew the
four screws. Rotate the
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.
– As far as possible, use a dust extraction system suita-
ble for the material.
– 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.
Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Operation

Starting Operation

Inserting the Battery
-1
[min ] [m/s]
Use only original Bosch lithium ion batteries with the
voltage listed on the nameplate of your power tool.
10000 80
Using other batteries can lead to injuries and pose a fire
hazard.
Insert the charged battery 4 from the front into the base of the
power tool until the battery is securely locked.
10000 80
Switching On and Off
To start the power tool, push the On/Off switch 2 forwards.
To lock the On/Off switch 2, press the On/Off switch 2 down
10000 45
at the front until it latches.
To switch off the power tool, release the On/Off switch 2 or,
if it is locked, briefly push down the back of the On/Off switch
2 and then release it.
When not using the power tool, switch it off in order to save
energy.
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.
Working Advice
Exercise caution when cutting slots in structural walls;
see Section "Information on Structures ".
Clamp the workpiece if it does not remain stationary
due to its own weight.
Do not strain the machine so heavily that it comes to a
standstill.
After heavily straining the power tool, continue to run
it at no-load for several minutes to cool down the acces-
sory.
