Connecting the dust extraction system (see figure A)
The dust extraction system (13) is only designed for use
with the sanding plate (14); it serves no purpose when used
together with other application tools.
Always connect a dust extraction system for sanding.
Remove the application tool and the depth stop (11) for fit-
ting the dust extraction system (13) (accessory).
Slide the dust extraction system (13) as far as it will go over
the tool holder (8) onto the collar of the power tool. Turn the
dust extraction system to the required position (not directly
under the power tool). Push the clamping lever (16) shut to
fix the dust extraction system in position.
Attach the dust extraction adapter (18) of the dust extrac-
tion hose (19) to the dust extraction outlet (17). Connect
the dust extraction hose (19) to a dust extractor (access-
ory).
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 (1) 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 (1) fur-
ther forwards so that "I" appears on the switch.
To switch off the power tool and the worklight, slide the on/
off switch (1) 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 (1).
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 (5).
The required orbital stroke rate is dependent on the material
and the work conditions and can be determined using prac-
tical tests.
Orbital stroke rate level "6" is recommended for sawing, cut-
ting and sanding harder materials, such as wood or metal;
Bosch Power Tools
orbital stroke rate level "4" is recommended for softer ma-
terials, such as plastic.
Note: For certain application tools (e.g. sanding and RIFF
application tools) the orbital stroke rate should be limited to
a maximum of 2/3. If the orbital stroke rate is too high, this
will considerably increase the wear on the application tool
and can also lead to premature breakdown. Please take note
of the information on the application tools or on the pack-
aging of the application tool.
Working Advice
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
Always wait until the power tool has come to a com-
u
plete stop before placing it down.
Note: Do not keep the ventilation slots (4) on the power tool
closed when working as this will reduce the service life of the
power tool.
Operating principle
The oscillating drive causes the application tool to oscillate
back and forth up to 20000 times per minute. This enables
precise work in the tightest of spaces.
Use a consistent, low contact pressure when
performing work; otherwise, the performance
will be impaired and the application tool may
jam.
While working, move the power tool back and
forth to prevent the application tool overheat-
ing and jamming.
Sawing
Use only undamaged saw blades that are in perfect
u
condition. Bent or dull saw blades can break, negatively
influence the cut, or lead to kickback.
When sawing lightweight materials, take into account
u
the statutory provisions and recommendations of the
material manufacturers.
Plunge cuts may only be applied to soft materials,
u
such as wood, gypsum board, etc.
Before using HCS saw blades to saw into wood, chipboard,
building materials, etc., check these saw blades for foreign
objects, such as nails, screws, etc. Remove the foreign ob-
jects as required or use bi-metal saw blades.
Cutting
Note: When cutting wall tiles, please bear in mind that the
application tools are subject to high wear if used for exten-
ded periods.
Sanding
The material removal rate and sanding result are primarily
determined by the choice of sanding sheet, the preselected
orbital stroke rate level and the contact pressure.
