– 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.
Only use grinding points with a matching shank diame-
ter. A grinding point/accessory with a shank diameter that
does not fit the tool holder (see "Technical Data"), can not
be clamped properly and will damage the collet chuck.
The application tool must be clamped at least 10 mm.
The inner shank dimension L
can be used to calculate the
0
maximum permitted speed of the application tool from the
specifications provided by manufacturer of the application
tool. It must not be less than the maximum speed of the
power tool.
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
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.
Bosch Power Tools
Restarting Protection
The restarting protection feature prevents uncontrolled re-
starting of the machine after an interruption in the power sup-
ply.
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.
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.
Protect the abrasive wheels from impacts.
Maintenance and Service
Maintenance and Cleaning
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.
For safe and proper working, always keep the machine
and ventilation slots clean.
