Selecting A Sanding Pad; Dust/Chip Extraction - Bosch AdvancedOrbit 18 Manual Original

To ensure optimum dust extraction, make sure that the
punched holes in the sanding sheet (10) are aligned with the
drilled holes in the sanding pad (6).
You can use the alignment aid (11) to precisely align the
sanding sheet (10) on the sanding pad (6). Place the sand-
ing sheet onto the alignment aid with the hook-and-loop
fastening facing upwards. Press the cams of the alignment
aid into the two holes in the sanding pad and unroll the sand-
ing sheet from the alignment aid. Firmly press the sanding
sheet into place.
Note: The sanding sheet must be positioned correctly in or-
der to ensure low vibration of the power tool during opera-
tion.

Selecting a Sanding Pad

The power tool can be fitted with sanding pads of various
hardnesses, depending on the application:
– Medium sanding pad (black): Suitable for all sanding
work, universal application.
– Soft sanding pad (grey, accessory): Suitable for interme-
diate and fine sanding even on curved surfaces.
Changing the Sanding Pad (see figures D–E)
Note: Replace damaged sanding pads (6) immediately.
Remove the sanding sheet or polishing tool. Unscrew the
four screws completely (12) and remove the sanding pad
(6).
Clean the top of the new sanding pad (6). Lubricate the
outer ring (shaded in grey in the figure) with a thin layer of
synthetic grease.
Attach the new sanding pad (6) and retighten the four
screws.
Note: Damaged sanding pads must only be replaced by an
after-sales service centre authorised to work with Bosch
power tools.

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.

Self-generated Dust Extraction with Dust Box (see
figures F–I)
Place the dust box (5) onto the extraction outlet (14) until it
clicks into place.
You can easily check the filling level of the dust box (5)
through the transparent container.
To empty the dust box (5), rotate and pull it downwards.
Before opening the dust box (5), knock the dust box against
a firm surface as shown in the figure to loosen the dust from
the filter element.
Holding the dust box (5) firmly, flap the filter element (15)
upwards out of the way and empty the dust box. Use a soft
brush to clean the flaps of the filter element (15).
Note: In order to ensure optimum dust extraction, empty the
dust box (5) in good time and clean the filter element (15)
regularly.
When working on vertical surfaces, hold the power tool with
the dust box (5) facing downwards.
External Dust Extraction (see figure J)
Attach a vacuum hose (16) with a dust extraction adapter
(19) to the extraction outlet (14). Connect the vacuum hose
(16) and the dust extraction adapter (19) to a dust ex-
tractor. You will find an overview of connecting to various
dust extractors at the end of these operating instructions.
The dust extractor must be suitable for the material being
worked.
When extracting dry dust that is especially detrimental to
health or carcinogenic, use a special dust extractor.
When working on vertical surfaces, hold the power tool with
the dust extraction hose facing downwards.
Auxiliary Handle (see figure K)
The auxiliary handle (7) enables comfortable handling and
optimum power distribution, with a high sanding removal
rate in particular.
You can remove the auxiliary handle in order to sand close to
edges. Unscrew and remove the wing nut (18) and pull the
screw (17) out of the housing. Then pull the auxiliary handle
(7) off towards you.
To reinstall the auxiliary handle (7), push it onto the housing
from the front such that the ridges on the auxiliary handle
engage in the recesses on the housing. Firmly fix the auxili-
ary handle in place using the screw (17) and the wing nut
(18).
Adjusting the Auxiliary Handle (see figure L)
The auxiliary handle can be set to three positions. To change
the position, loosen the wing nut (18) (by approx. 2–3
turns). Set the auxiliary handle and retighten the wing nut.
