LED
3× continuous green light
2× continuous green light
1× continuous green light
1× flashing green light
Temperature monitoring/overload protection indicator
The red LED indicator helps you to protect the rechargeable
battery against overheating and the motor against overload.
If the LED indicator is lit up permanently in red, the temper-
ature of the rechargeable battery is too high and the power
tool switches off automatically.
– Switch the power tool off.
– Allow the battery to cool down before you carry on work-
ing.
If the LED indicator is flashing red, then the power tool is
blocked and will switch off automatically.
Pull the power tool out of the workpiece.
The power tool will continue to work as soon as the blockage
is rectified.
Recommendations for Optimal Handling of the
Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to
50 °C. Do not leave the battery in your car in the summer, for
example.
Occasionally clean the ventilation slots on the battery using a
soft brush that is clean and dry.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
Fitting
Before carrying out any work on the power tool (e.g.
u
maintenance, tool change etc.), remove the battery
from the power tool. There is risk of injury from uninten-
tionally pressing the on/off switch.

Changing the tool
Wearing protective gloves while fitting and changing
u
router bits is recommended.
Original router bits from the extensive range of Bosch ac-
cessories are available from your specialist dealer.
Changing the collet (see figures A–B)
Depending on the router bit used, you may have to change
the cap nut with the collet (9) before fitting the router bit.
If the right collet for your router bit is already fitted, please
follow the work steps in the following section.
The collet (15) must sit in the cap nut with a small amount of
play. The cap nut (9) must be easy to fit. If the cap nut or col-
let is damaged, replace it 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 off-
set by 60° are possible.
Capacity
Unscrew the cap nut (9) anticlockwise using the open-ended
60–100 %
spanner (18).
30–60 %
If required, clean all the parts you want to fit with a soft
5–30 %
brush or by blowing them clean with compressed air before
assembling them.

Loosely tighten the cap nut.
Slide the spindle locking lever (7) back into the housing.

Wearing protective gloves while fitting and changing
u
router bits is recommended.
Router bits are available in a wide variety of designs and
qualities depending on the intended application.
Router bits made of high-performance high-speed steel
(HSS) are suited to machining soft materials such as soft-
wood and plastic.
Router bits with carbide tips are especially suitable for
hard and abrasive materials such as hardwood and alu-
minium.
Original router bits from the extensive range of Bosch ac-
cessories are available from your specialist dealer.
Only use undamaged and clean router bits.
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 off-
set by 60° are possible.
Unscrew the cap nut (9) anticlockwise using the open-ended
spanner (18).
Slide the router bit into the collet. The shank of the router bit
must be immersed at least 20 mm into the collet.
Retighten the cap nut by turning in clockwise direction.
