Always connect a dust extraction system for sanding.
Remove the application tool and the depth stop (12) for fit-
ting the dust extraction system (17) (accessory).
Slide the dust extraction system (17) 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 (18) shut to
fix the dust extraction system in position.
Plug the tool sleeve of the extraction hose (15) onto the ex-
traction outlet (16). Connect the dust extraction hose (15)
to a dust extractor (accessory).
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
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Switching On/Off
Make sure that you are able to press the On/Off switch
u
without releasing the handle.
To switch on the power tool, slide the on/off switch (2) for-
ward so that "I" appears on the switch.
The electronic soft start limits the torque when the power
tool is switched on and increases the service life of the mo-
tor.
The Constant Electronic keeps the orbital stroke rate at no
load and under load virtually consistent, guaranteeing uni-
form performance.
To switch off the power tool, slide the on/off switch (2)
backwards so that "0" appears on the switch.
The 180° light band (7) improves visibility in the immediate
work area. It is automatically switched on and off with the
power tool.
Do not look directly into the worklight; it can blind
u
you.
Preselecting the orbital stroke rate
You can even preselect the required orbital stroke rate dur-
ing operation using the orbital stroke rate preselection
thumbwheel (4).
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.
Practical Advice
Pull the plug out of the socket before carrying out any
u
work on the power tool.
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 (3) 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 by 2.8° 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 ap-
plication tool may jam.
While working, move the power tool back
and forth to prevent the application tool
overheating 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.
Only immaculate sanding sheets achieve good sanding per-
formance and make the power tool last longer.
Be sure to apply consistent contact pressure in order to in-
crease the lifetime of the sanding sheets.
Excessively increasing the contact pressure will not lead to
increased sanding performance, rather it will cause more
severe wear of the power tool and of the sanding sheet.
