Note: The battery is supplied partially charged. To ensure full
capacity of the battery, completely charge the battery in the
battery charger before using your power tool for the first time.
The lithium-ion battery can be charged at any time without re-
ducing its service life. Interrupting the charging procedure
does not damage the battery.
The lithium ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
 Do not continue to press the On/Off switch after the
machine has been automatically switched off. The bat-
tery can be damaged.
Observe the notes for disposal.
Removing the battery (see figure A)
– To remove the battery 9, press the unlocking buttons 16
and pull the battery out of the machine to the rear. Do not
exert any force.

Changing the Tool
 When inserting an application tool, pay attention that
the 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 not be controlled.
 Use only flawless tool bits that are not worn. Defective
tool bits can break, for example, and cause injury or dam-
age.
 Only use brand accessories for grinding, sanding,
brushing, polishing, routing and cut-off grinding from
the dealer for the power tool, which are approved for a
speed of 35000 rpm and which have a shank with an
outside diameter of 3.2 mm.
Inserting (see figure B)
– Press the spindle lock 5 and turn the clamping nut 12 by
hand until locked.
1 619 P11 460 | (26.11.13)
– Press and hold the spindle lock and loosen the clamping
nut 12 with the open-end spanner 17 by turning it in an an-
ticlockwise direction.
– Insert the dust-free application tool (e.g. holding rod 2,
grinding accessory 3 or drill bit) into the collet 13 of the
collet chuck 19.
Note: Ensure that the shank 18 of the application tool sits in
as far as possible, but at least 10 mm into the collet chuck.
– Press and hold the spindle lock 5 and tighten the applica-
tion tool by turning the clamping nut 12 with the open-end
spanner 17 in a clockwise direction.
Removing
– Loosen the clamping nut 12 as previously described and
remove the application tool.
Mounting a Cutting Disc (see figure C)
Cutting discs reinforced with fibreglass are included in the
scope of delivery. They can be used for grooving, routing and
cutting metal, wood and plastic.
– Insert the holding rod 2 into the collet (see "Inserting",
page 18).
– Press and hold the spindle lock 5 and completely unscrew
the screw on the holding rod 2 using the screwdriver 17.
– Attach the cutting disc 1 to the holding rod 2 and reinsert
and tighten the screw.
Changing the Collet Chuck (see figure D)
– 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-end spanner 17 by turning it in an an-
ticlockwise direction.
– Remove the clamping nut 12 together with the collet chuck
19.
– Insert the required collet chuck into the drive spindle 20.
– Screw the clamping nut 12 onto the drive spindle 20 and
tighten it slightly in a clockwise direction using the open-
end spanner 17.
Replacing the Dust Protection Cap (see figure E)
Two dust protection caps are included in the scope of deliv-
ery.
Use the dust protection cap 11 when you need a good grip for
detailed work.
Use the dust protection cap 21 when you have to work close
to the workpiece surface.
The dust protection cap largely prevents the penetration of
dust into the tool holder during operation. When inserting the
tool, pay attention that the dust protection cap is not damaged.
– Unscrew the dust protection cap used.
– Screw on the new dust protection cap and tighten it.
