1 609 92A 01H | (4.12.12) Bosch Power Tools
The battery is equipped with a NTC temperature control
which allows charging only within a temperature range of be-
tween 0 °C and 45 °C. A long battery service life is achieved
in this manner.
Observe the notes for disposal.
Removing the battery
The battery 7 is equipped with two locking levels that should
prevent the battery from falling out when pushing the battery
unlocking button 6 unintentionally. As long as the battery is
inserted in the power tool, it is held in position by means of a
spring.
To remove the battery 7, press the battery unlocking button 6
and pull the battery upward out of the power tool. Do not ex-
ert any force.
Battery Charge-control Indication (see figure A)
The three green LEDs of the battery charge-control indicator
10 indicate the charge condition of the battery 7. For safety
reasons, it is only possible to check the status of the charge
condition when the machine is at a standstill.
Press button 9 to indicate the charge condition. This is also
possible when the battery 7 is removed.
When no LED lights up after pushing button 9, then the bat-
tery is defective and must be replaced.
Mounting the Grinding Tools (see figure B)
 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.
 Only use properly fitting and undamaged open-end
spanners (see “Technical Data”).
– Clean the grinder spindle 3 and all parts to be mounted.
– Hold the grinder spindle 3 with open-end spanner 11 by
the spanner flats .
Loosen the clamping nut 2 with open-end spanner 12 by
applying it to the spanner flats and turning in anticlockwise
direction.
– Insert the clamping shaft of the grinding tool to the stop in-
to the collet chuck 1.
– Hold the grinder spindle 3 firmly with open-end spanner
11 and clamp the tool bit with open-end spanner 12 by the
spanner flats , 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.
 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
 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.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Operation
Starting Operation
Inserting the battery
 Use only original Bosch lithium ion batteries with the
voltage listed on the nameplate of your power tool. Using
other batteries can lead to injuries and pose a fire hazard.
Insert the charged battery 7 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 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.
To save energy, only switch the power tool on when using it.
Restarting Protection
The restarting protection feature prevents uncontrolled restart-
ing of the machine after an interruption in the power supply.
To restart the operation, switch the On/Off switch 5 to the
Off position and start the machine again.
Note: When switching off and on again very quickly, it is pos-
sible that the restarting protection is triggered; this will pre-
vent the power tool from starting, although the On/Off switch
5 is actuated. Set the On/Off switch 5 to the off position, and
then switch the power tool on again.
