Assembly
Battery Charging

Use only the chargers listed in the technical data. Only
these chargers are matched to the lithium-ion battery of
your power tool.
Note: The battery supplied is 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.
Removing the battery
To remove the battery 1 , press the battery unlocking button 2
and pull the battery upward out of the power tool. Do not ex-
ert any force.
Battery Charge-control Indication
Changing the Tool

Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.), remove the battery from the
power tool.
There is danger of injury when unintentionally
actuating the On/Off switch.

It is recommended to wear protective gloves when in-
serting or replacing router bits.
Replacing the Collet (see figures A–B)
Depending on the routing tool being used, the tightening nut
with the collet
9 may need to be replaced before inserting the
router bit.
When the right collet for your router bit is already mounted,
follow the work steps as described under “Inserting a Router
Bit”.
The collet 15 must have a slight amount of play when seated
in the tightening nut. The tightening nut 9 must assemble eas-
ily. Should the tightening nut or collet be damaged, replace
immediately.
Pull out the spindle locking lever 7 up to the marking arrow 6
on the housing. If necessary, turn the motor spindle manually
until it is locked in place. Six positions offset by 60° are possi-
ble.
Unscrew the tightening nut 9 with open-end spanner 18 turn-
ing in anticlockwise direction.
If required, clean all parts to be mounted prior to assembling,
using a soft brush or by blowing out with compressed air.
Start the new tightening nut on tool holder 16 .
Hand-tighten the tightening nut.
Slide the spindle locking lever 7 back into the housing.

Do not tighten the tightening nut of the collet without a
router bit inserted.
Otherwise the collet can be damaged.
Inserting a Router Bit (see figure C)
Depending on the application, router bits are available in the
most different designs and qualities.
Router bits made of high speed steel (HSS) are suitable for
the machining of soft materials, e. g. softwood and plastic.
Milling cutters with carbide tips are specially designed for
hard and abrasive materials, such as hardwood.
Original router bits from the extensive Bosch accessories pro-
gram are available at your specialist shop.
Only use clean router bits that are in perfect condition.
Pull out the spindle locking lever 7 up to the marking arrow 6
on the housing. If necessary, turn the motor spindle manually
until it is locked in place. Six positions offset by 60° are possi-
ble.
Loosen the tightening nut 9 with the open-end spanner by
turning in anticlockwise direction 18 .
Insert the router bit into the collet. The shank of the router bit
must be immersed at least 20 mm into the collet.
Retighten the tightening nut by turning in clockwise direction.
Slide the spindle locking lever 7 back into the housing.

Do not tighten the tightening nut of the collet without a
router bit inserted.
Otherwise the collet can be damaged.
