Dust/Chip Extraction - Bosch GWS 18V-10 PC Professional Originalbetriebsanleitung

After fitting the hub flange
and the grinding/cutting
disc, the free thread length
of the grinding spindle must
be at least 4 mm.
Ensure that the abrasive
tool is firmly seated, so that
it does not twist away from
the spindle in the runout of the power tool.
A plastic part (O-ring) is fitted around the cent-
ring collar in the hub flange (13). If the O-ring
is missing or damaged, the hub flange (13)
must be replaced before operation can re-
sume.
After fitting the abrasive tool, check that the abrasive
u
tool is fitted correctly and can turn freely before
switching on the power tool. Make sure that the abras-
ive tool does not brush against the protective guard or
other parts.
Flap disc
Always fit the hand guard (20) when working with the
u
flap disc.
Rubber Sanding Pad
Always fit the hand guard (20) when working with the
u
rubber sanding pad (21).
See the graphics page for fitting instructions.
Slide the rubber sanding pad (21) onto the grinding spindle
(19).
Press the sanding sheet (22) firmly onto the underside of
the rubber sanding pad (21).
Screw on the round nut (23) and tighten with a two-pin
spanner.
Cup brush/disc brush
Always fit the hand guard (20) when working with the
u
cup brush or disc brush.
See the graphics page for fitting instructions.
The cup brush/disc brush must be screwed onto the grinding
spindle until it rests firmly against the grinding spindle flange
at the end of the grinding spindle thread. Tighten the cup
brush/disc brush with an open-ended spanner.
Carbide Grinding Head
A grinding head may be used only with a suitable pro-
u
tective guard.
Approved abrasive tools
You can use all the abrasive tools mentioned in these operat-
ing instructions.
The permissible speed [rpm] or the circumferential speed
[m/s] of the abrasive tools used must at least match the val-
ues given in the table.
It is therefore important to observe the permissible rota-
tional/circumferential speed on the label of the abrasive
tool.

Rotating the Machine Head (GWS 18V-10 PC)
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
The machine head can be
rotated in 90° increments.
In this way, the on/off
switch can be brought into
a more favourable handling
position for particular ap-
plications, e.g. for left-
handed tool users.
Completely unscrew the
four screws. Rotate the ma-
chine head carefully, without removing it from the hous-
ing, into the new position. Screw in and retighten the four
screws.

Dust/Chip Extraction

Dust 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 dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– 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 ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
