Switching On and Off
To start the machine, push the On/Off switch 5 for-
ward so that the "I" is indicated on the switch.
To switch off the machine, push the On/Off switch
5 toward the rear so that the "0" is indicated on the
switch.
The lithium ion battery is protected against deep dis-
charging by the "Electronic Cell Protection (ECP)".
When the battery is empty, the machine is switched
off by means of a protective circuit: The inserted tool
no longer rotates.
☞
Note: If the machine should automatically
switch off because of a discharged or over-
heated battery, make sure to set the
machine's On/Off switch 5 to off. Charge the
battery and allow it to cool down before
restarting the machine. Otherwise the battery
can become damaged.
Preselecting the Orbital Stroke Rate
With the thumbwheel for preselection of the orbital
stroke rate 6, 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 7 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 20000 times per minute
for 2.8°. This allows for precise work in narrow
spaces.
Sawing
❏ Use undamaged faultless saw blades
only. Deformed, blunt saw blades or saw blades
that are otherwise damaged can break.
❏ When sawing light building materials,
observe the statutory provisions and the
recommendations of the material suppli-
ers.
❏ Plunge cuts may only be applied to soft
materials, such as wood, gypsum plaster
boards, etc.!
12–English
Sanding
The removal rate and the sanding pattern are pri-
marily 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.
Use only original Würth sanding accessories.
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.
Temperature Dependent Overload
Protection
When using as intended for, the machine cannot be
overloaded. In case of excessive loading or when
exceeding the allowable battery temperature range
of 0–70 °C, the speed is reduced or the machine
switches off. In case of reduced speed, the machine
will not run at full speed until after reaching the
allowable battery temperature again. In case of
automatic shut-off, switch the machine off, allow the
battery to cool down and then switch the machine on
again.
Recommendations for Optimal
Handling of the Battery
Protect the battery against moisture and water.
Store the battery only within a temperature range
between 0 °C and 45 °C. As an example, do not
leave the battery in the car in summer.
A significantly reduced working period after charg-
ing indicates that the battery is used and must be
replaced.
Observe the notes for disposal.
