Dust/Chip Extraction; Changing The Sanding Plate (See Figure C); Special Sanding Plates - Bosch PDA 180 Manual Original

12 | English
The given vibration level and noise emission value represent
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 the hands warm,
and organising workflows correctly.
Assembly
Pull the plug out of the socket before carrying out any
u
work on the power tool.

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.
External dust extraction (see figure A)
Fit a dust extraction hose (7) onto the extraction outlet (3).
Connect the dust extraction hose (7) to an extractor. 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.
Changing the sanding sheet (see figure B)
Remove dirt and dust from the sanding plate (5), e.g. with a
brush, before attaching a new sanding sheet.
To ensure optimum dust extraction, make sure that the
punched holes in the sanding sheet are aligned with the
drilled holes in the sanding plate.

The sanding plate (5) is fitted with a hook-and-loop fasten-
ing, allowing sanding sheets with a similar backing to be se-
cured quickly and easily.
Tap the hook-and-loop fastening of the sanding plate (5) be-
fore fitting the sanding sheet (4) to facilitate maximum adhe-
sion.
Position the sanding sheet (4) so that it is flush with one a
side of the sanding plate (5), then place the sanding sheet
on the sanding plate and press it on firmly.
To remove the sanding sheet (4), take hold of it by an edge
and pull it away from the sanding plate (5).
Sanding accessories such as fleece/polishing felt are at-
tached to the sanding plate in the same way.
Choosing the sanding sheet
Different sanding sheets are available, depending on the ma-
terial you are working with and the required surface removal
rate:
Application
Can be used to work on all materials including
wood, paint, filler, varnish, hard and soft wood
as well as chipboard and metal.
For pre-sanding, e.g. of rough and un-
even beams and boards
For surface sanding and levelling of
slight irregularities
For finish-sanding and fine sanding of
hardwoods
For any finishing work, such as polishing (metal and stone in
particular), use fleece/polishing felt.
Different types of fleece and polishing felts should be used
depending on the surface finish required on the workpiece.
Changing the sanding plate (see figure C)
❶ Push the SDS slider for sanding plate release (6) all the
way to the right.
❷ Remove the sanding plate (5).
❸ Move the sanding plate (5) against the sanding plate
holder from below and press it firmly into place.
❹ Push the SDS slider for sanding plate release (6) all the
way to the left.
If the front tip of the sanding sheet has worn down, the en-
tire sanding plate can be removed, rotated 120° and put
back on again for reuse.

Special Sanding Plates

You can replace the standard supplied sanding plate (5) with
one of the special sanding plates that are available as ac-
cessories.
Special sanding plates are fitted in exactly the same way as
the standard supplied sanding plate.
Likewise, each sanding sheet is attached and removed in ex-
actly the same way as the original sanding sheet.
