Battery Charging
Use only the chargers listed in the technical data. Only
u
these chargers are matched to the lithium-ion battery of
your power tool.
Note: The battery is supplied partially charged. To ensure
full battery capacity, fully charge the battery in the charger
before using your power tool for the first time.
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
Do not continue to press the On/Off switch after the
u
power tool has automatically switched off. The battery
can be damaged.
Follow the instructions on correct disposal.
Removing the Battery
The battery (7) is equipped with two locking levels to pre-
vent the battery from falling out when pushing the battery re-
lease button (6) unintentionally. As long as the battery is in-
serted in the power tool, it is held in position by means of a
spring.
To remove the battery (7), press the release button (6) and
pull the battery out of the power tool. Do not use force to
do this.
Battery charge indicator
The green LEDs on the battery charge indicator indicate the
state of charge of the battery. For safety reasons, it is only
possible to check the state of charge when the power tool is
not in operation.
Press the button for the battery charge indicator or
show the state of charge. This is also possible when the bat-
tery is removed.
If no LED lights up after pressing the button for the battery
charge indicator, then the battery is defective and must be
replaced.
Note: The state of charge of the battery is also displayed on
the user interface (13) (see "Status indications", page 20).

Fitting the Abrasive Tools (see figure A)
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
Only use open-ended spanners that are suitable and
u
undamaged (see "Technical Data").
– Clean the grinding spindle (3) and all the parts to be fit-
ted.
– Use an open-ended spanner (10) on the spanner flat of
the grinder spindle (3) to hold it in place.
Loosen the clamping nut (2) by placing an open-ended
spanner (11) on the spanner flat and turning it counter-
clockwise.
– Insert the straight shank of the grinding tool all the way
into the collet (1).
– Hold the grinding spindle (3) with the open-ended span-
ner (10) and tighten the application tool by placing the
open-ended spanner (11) on the spanner flat and turning
it clockwise.
to
The grinding tools must run completely concentrically. Do
not continue to use damaged grinding tools that are out of
balance. If the grinding tools are out of balance, they should
be replaced.
Do not, under any circumstances, tighten the collet
u
with the clamping nut until a grinding tool has been
fitted. The collet may otherwise become damaged.
Only use mounted points with an appropriate shank
u
diameter. A mounting point with a shank diameter which
does not correspond to the tool holder of the power tool
(see "Technical data") cannot be held properly and will
damage the collet chuck.
Capacity
The application tool must be clamped at least 10 mm.
