Dust/Chip Extraction
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Connecting the Dust Extraction
For sanding, always connect dust extraction.
Place a vacuum hose 4 (accessory) onto the vac-
uum connection 3. Connect the vacuum hose 4
with a vacuum cleaner (accessory). An overview
for the connection of various vacuum cleaners
can be found at the end of these instructions.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
Bosch Power Tools
Operation
Starting Operation
Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Switching On and Off
To start the machine, push the On/Off switch 1
forward so that the "I" is indicated on the switch.
To switch off the machine, push the On/Off
switch 1 toward the rear so that the "0" is indi-
cated on the switch.
Preselecting the Orbital Stroke Rate
With the thumbwheel for preselection of the or-
bital stroke rate 2, you can preselect the required
orbital stroke rate, even during operation.
The required stroke rate depends on the material
and the working conditions and can be deter-
mined through practical testing.
Working Advice
Note: Do not cover off the venting slots 6 of the
machine while working, as this reduces the
working life of the machine.
While working with HCS tools make sure that
the covering of the tools is undamaged.
Operating Principle
Due to the oscillating drive the application tool/
accessory swings up to 21000 times per minute
for 2.8°. This allows for precise work in narrow
spaces.
Work with low and uniform appli-
cation pressure, otherwise, the
working performance will decline
and the application tool can be-
come blocked.
While working, move the machine
back and forth, so that the appli-
cation tool does not heat up ex-
cessively and become blocked.
