Fitting
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.
Charging the Battery
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 (see figure A)
To remove the battery (9), press the release button (16)
and pull the battery to the rear and out of the power tool. Do
not use force to do this.
Battery charge indicator

dicate the state of charge of the battery (9).

When inserting an application tool, ensure that the
u

shank of the application tool is firmly seated in the
tool holder. When the shank of the application tool is not
inserted deep enough in the tool holder, the application
tool can become loose again and cannot be controlled.
Do not use application tools that are worn or in other-
u
wise less than perfect condition. Defective application
tools can break, for example, causing material damage
and personal injury.
Only use brand accessories for grinding, sanding,
u
brushing, polishing, routing and cut-off grinding from
the dealer for the power tool, which are approved for
a speed of 35,000 min
an outside diameter of 3.2 mm.
Inserting the Application Tool (see figure B)
– Press the spindle lock (5) and turn the clamping nut (12)
by hand until locked.
– Press and hold the spindle lock and loosen the clamping
nut (12) with the open-ended spanner (17) by turning it
anticlockwise.
– Insert the dust-free application tool (e.g. holding rod (2),
grinding accessory (3) or drill bit) into the tool holder
(13) of the collet (19).
Note: Ensure that the shank (18) of the application tool sits
