Assembly
Inserting a Router Bit (see figure A)
Before any work on the machine itself, pull the mains
plug.
It is recommended to wear protective gloves when in-
serting or replacing router bits.
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.
Carbide tipped router bits (HM)
are particularly suitable for
hard and abrasive materials, e. g. hardwood and aluminium.
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.
– Swivel the spindle lock lever
6
anticlockwise all the way
(
). If necessary, turn the motor spindle by hand until you
hear it engage.
– Loosen the tightening nut
4
with the open-end spanner
31
(width across flats of 19 mm) by turning it clockwise (
).
– Slide the router bit into the collet. The bit shank must be in-
serted into the collet at least up to the mark.
– Tighten the tightening nut
4
with the open-end spanner
31
(width across flats of 19 mm) by turning it anticlockwise.
Close the spindle lock lever
6
completely.
Do not insert any router bits with a diameter greater
than 50 mm.
These router bits will not fit through the base
plate.
Do not tighten the tightening nut of the collet without a
router bit inserted.
Otherwise the collet can be damaged.
Dust/Chip Extraction (see figure B)
Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one’s health. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable
for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the mate-
rials to be worked.
Prevent dust accumulation at the workplace.
Dusts can
easily ignite.
Connecting the Dust Extraction (see figure B)
Attach an extraction hose (Ø 35 mm)
32
(accessory) to the
port
30
in the base plate
13
. Connect the extraction hose
32
to a vacuum cleaner (accessory).
The machine can be plugged directly into the receptacle of a
Bosch all-purpose vacuum cleaner with remote starting con-
trol. The vacuum cleaner starts automatically when the ma-
chine is switched on.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Operation
Starting Operation
Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
GOF 1250 LCE:
Once the mains voltage has been applied,
the light ring
3
lights up continuously to illuminate the work-
piece surface.
Insert the battery (see section “Changing the Battery”,
page 19). In some versions 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.
Preselecting the Speed
The required speed can be preselected with the thumbwheel
28
(also while running).
1 – 2
low speed
3 – 4
medium speed
5 – 6
high speed
The required speed is dependent on the material and the
work conditions and can be determined by practical trials.
After longer periods of working at low speed, allow the ma-
chine to cool down by running it for approx. 3 minutes at max-
imum speed with no load.
