Do not insert a router bit with a diameter larger
u
than 50 mm when the guide bushing is not mounted.
These router bits will not fit through the base plate.
Do not, under any circumstances, tighten the collet
u
with the tightening nut until a router bit has been fit-
ted. The collet may otherwise become damaged.
Dust/Chip Extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Connecting the dust extraction system (see figure B)
Attach an extraction hose (dia. 35 mm) (32) (accessory) to
the fitted dust extraction adapter. Connect the dust extrac-
tion hose (32) to a dust extractor (accessory).
The power tool can be directly connected to the plug socket
of a Bosch all-purpose dust extractor with remote starter.
This dust extractor is started up automatically when the
power tool is switched on.
The dust extractor must be suitable for the material being
worked.
When extracting dry dust or dust that is especially detri-
mental to health or carcinogenic, use a special dust ex-
tractor.
Operation
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool.
Starting Operation
GOF 1250 LCE: Once the mains voltage has been applied,
the light ring (3) lights up continuously to illuminate the
workpiece surface.
Insert the battery (see "Changing the Battery
(GOF 1250 LCE) (see figure M)", page 21). In some ver-
sions the battery is already inserted. Remove the seal on the
battery to activate it.
Bosch Power Tools
Use the button (17) to set the required unit of measure.
Preselecting the speed
You can preselect the required speed using the speed
preselection thumbwheel (28), even during operation.
1−2
low speed
3−4
medium speed
5−6
high speed
The values shown in the table are guide values. The required
speed is dependent on the material and the work conditions
and can be determined by practical trials.

After working at a low speed for an extended period, you
should operate the power tool at the maximum speed for ap-
proximately three minutes without load to cool it down.
Switching on/off
Before switching on, set the required routing depth.
To switch on the power tool, press the on/off switch (29)
and keep it pressed.
Press the lock-on button (2) to lock the on/off switch (29) in
this position.
To switch off the power tool, release the on/off switch (29);
or, if the switch is locked with the lock-on button (2), briefly
press the on/off switch (29) and then release it.
Constant electronic control
The Constant Electronic keeps the speed at no load and un-
der load virtually consistent, guaranteeing uniform perform-
ance.
Soft start
The electronic soft start limits the torque when the power
tool is switched on and increases the service life of the mo-
tor.
Overload protection
The overload protection prevents impermissibly high current
consumption in the event of extreme overload. This can lead
to a reduction in motor speed and power output or in ex-
treme cases to motor standstill.
Once the load has been removed from the power tool, the
motor immediately runs up or back to working speed.
