4. Operation
l 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.
Starting Operation
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 indicated on the switch.
Preselecting the Orbital Stroke Rate
With the thumbwheel for preselection of the orbital 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 determined through
practical testing.
Working Advice
Note: Do not cover off the venting slots 3 of the machine
while working, as this reduces the working life of the
machine.
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 application pressure,
otherwise, the working performance will decline
and the application tool can become blocked.
While working, move the machine back and forth, so that
the application tool does not heat up excessively and
become blocked.
Sawing
l Use undamaged faultless saw blades only.
Deformed, blunt saw blades or saw blades that are
otherwise damaged can break.
l When sawing light building materials, observe the
statutory provisions and the recommendations of
the material suppliers.
l Plunge cuts may only be applied to soft materials,
such as wood, gypsum plaster boards, etc.!
Before sawing with HSS saw blades in wood, particle
board, building materials, etc., check these for foreign
objects such as nails, screws, or similar. If required, remove

foreign objects or use BIM saw blades.
Sanding
The removal rate and the sanding pattern are primarily
determined by the choice of sanding sheet, the preset
oscillation rate and the applied pressure.
Only flawless sanding sheets achieve good sanding
capacity and extend the service life of the machine.
Pay attention to apply uniform sanding pressure; this
increases the working life of the sanding sheets.
Intensifiying the sanding pressure does not lead to an
increase of the sanding capacity, but to increased wear of
the machine and the sanding sheet.
For precise on-the-spot sanding of edges, corners and hard
to reach areas, it is also possible to work only with the tip or
an edge of the sanding plate.
When selectively sanding on the spot, the sanding sheet
can heat up considerably. Reduce the orbital stroke rate
and allow the sanding sheet to cool down regularly.
A sanding sheet that has been used for metal should not be
used for other materials.
For sanding, always connect dust extraction.
Scraping
For scraping, select a high oscillation rate.
Work on a soft surface (e.g. wood) at a flat ange, and apply
only light pressure. Otherwise the scraper can cut into the
surface.
5. Maintenance and Service
Maintenance and Cleaning
l Before any work on the machine itself, pull the
mains plug.
l For safe and proper working, always keep the
machine and ventilation slots clean.
Clean Riff application tools (accessory) regularly with a wire
brush.
If the machine should fail despite the care taken in
manufacturing and testing procedures, repair should be
carried out by an after-sales service centre for Stayer.
