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 the Bosch range of
accessories.
Sanding accessories such as fleece/polishing felt are at-
tached to the sanding plate in the same way.
Orbital stroke rate level "4" is the maximum level that should
be used when working with sanding accessories such as
sanding sheets and sanding plates. If the orbital stroke rate
is too high, this will considerably increase the wear of the ac-
cessory and can also lead to premature breakdown. Please
take note of the information on the accessory or on the pack-
aging of the accessory.
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.
Connecting the dust extraction system (see figure A)
The dust extraction system is only designed for use with the
sanding plate (15); it serves no purpose when used together
with other accessories.
Always connect a dust extraction system for sanding.
Remove the accessory and the depth stop (10) for fitting the
dust extraction system.
Slide either the dust extraction system without click
connection (13) or the dust extraction system with click
1 609 92A 8RD | (07.08.2023)
connection (14) as far as it will go over the tool holder (8)
onto the collar of the power tool. Turn the dust extraction to
the required position (not directly under the power tool).
Push the clamping lever (17) shut to fix the dust extraction
system in position.
Connect the dust extraction system with the extraction hose:
– Dust extraction system without click connection (13): In-
sert the extraction hose (20) of the dust extractor into
the dust extraction adapter (19) and allow it to engage.
Attach the dust extraction adapter (19) to the extraction
outlet (18) of the dust extraction system (13).
– Dust extraction system with click connection (14): Insert
the extraction hose (20) of the dust extractor into the ex-
traction outlet (18) of the dust extraction system (14)
and allow it to engage.
Alternatively, the dust extraction adapter (19) can be in-
serted into the extraction outlet of the dust extraction
system (14) and the extraction hose (20) can be inserted
into the dust extraction adapter (19).
Connect the dust extraction hose (20) to a dust extractor.
You will find an overview of how to connect various dust ex-
tractors 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.
Operation
Starting Operation
Switching on/off
Make sure that you are able to press the On/Off switch
u
without releasing the handle.
To switch on the worklight, slide the on/off switch (2) for-
wards so that appears on the switch. The worklight im-
proves visibility in the immediate work area.
Do not look directly into the worklight; it can blind
u
you.
To switch on the power tool, slide the on/off switch (2) fur-
ther forwards so that "I" appears on the switch.
To switch off the power tool and the worklight, slide the on/
off switch (2) backwards so that "0" appears on the switch.
Note: If the power tool shuts down automatically because
the battery is flat or overheated, switch the power tool off
using the on/off switch (2).
Charge the battery or let it cool down before switching the
power tool on again. Failure to do so can damage the bat-
tery.
Preselecting the orbital stroke rate
You can even preselect the required orbital stroke rate dur-
ing operation using the orbital stroke rate preselection
thumbwheel (6).
The required orbital stroke rate is dependent on the material
and the work conditions and can be determined using prac-
tical tests.
