Fitting/changing the application tool
Remove the application tool if one has already been fitted.
To remove the application tool, use the hex key (12) to
loosen the clamping bolt (11) and remove the tool.
Position the required application tool (e.g. plunge cut saw
blade (10)) on the tool holder (7) so that the depressed
centre is facing downwards (see figure on the graphics page,
text on the application tool should be legible from above).
Turn the application tool to a position which is convenient
for the job at hand and allow it to lock into place in the cams
Selecting a sanding sheet
Different sanding sheets are available, depending on the material you are working with and the required surface removal rate:
Sanding sheet Material
– All wood and wood-based
materials (e.g. hardwood,
softwood, chipboard, con-
struction boards)
– Metal materials
– Paint
– Varnish
– Filler
– Bodyfiller
Attaching/changing the sanding sheet on the sanding
plate
The sanding plate (15) is fitted with a hook-and-loop fasten-
ing, allowing sanding sheets with a hook-and-loop backing to
be secured quickly and easily.
Tap the hook-and-loop fastening of the sanding plate (15)
before fitting the sanding sheet (16) to facilitate maximum
adhesion.
Position the sanding sheet (16) so that it is flush with one
side of the sanding plate (15), then place the sanding sheet
on the sanding plate and press it on firmly.
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.
To remove the sanding sheet (16), take hold of it by a corner
and pull it away from the sanding plate (15).
You can use all sanding sheets, polishing and cleaning
fleeces from the Delta 93 mm series in Bosch's range of ac-
cessories.
Sanding accessories such as fleece/polishing felt are at-
tached to the sanding plate in the same way.
1 609 92A 4D9 | (11.06.2018)
of the tool holder (7). Twelve positions offset by 30° are
possible for this.
Secure the application tool using the bolt (11). Tighten the
bolt using the hex key (12) until the rounded head of the bolt
is lying flat against the application tool.
Check that the application tool is seated securely. Ap-
u
plication tools that are attached incorrectly or are not se-
curely fixed in place may come loose during operation,
thereby putting you at risk.
Application
For pre-sanding, e.g. of rough and uneven beams and
boards
For surface sanding and levelling of slight irregularities
For finish-sanding and fine sanding of wood
For sanding down paint
For sanding undercoats (e.g. removing brushstrokes,
paint drips and paint runs)
For final sanding of primers prior to painting
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.
