standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.
Fitting
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Inserting the Router Bit (see figure A)
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.
– Swivel the spindle locking lever (6) anticlockwise as far
as it will go (➊). If necessary, turn the motor spindle by
hand until you hear it engage.
– Loosen the cap nut (4) with the open-ended span-
ner (31) (width across flats 19 mm) by turning it clock-
wise (➋).
– Slide the router bit into the collet. The bit shank must be
inserted into the collet at least up to the mark.
– Tighten the cap nut (4) with the open-ended span-
ner (31) (width across flats 19 mm) by turning it anti-
clockwise. Lock the spindle locking lever (6) fully back
into place.
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. Power tools marked
with 230 V can also be operated with 220 V.

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.
Use the button (17) to set the required unit of measure.
