Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one’s
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment addi-
tives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
• Provide for good ventilation of the working place.
• It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the mate-
rials to be worked.

Prevent dust accumulation at the workplace.
Dust can easily ignite.
Starting Operation
Inserting the battery

Use only original Würth lithium-ion batteries
with the voltage listed on the nameplate of
your power tool.
Using other batteries can lead to
injuries and pose a fire hazard.
Note: Use of batteries not suitable for the machine can lead
to malfunctions of or cause damage to the power tool.
Slide the charged battery
4
from behind into the foot of the
power tool. Push the battery fully into the foot.
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.
To save energy, only switch the power tool on when using it.
The worklight improves visibility in the immediate work area.
It is automatically switched on and off with the power tool.

Do not look directly into the work area illumina-
tion – your sight can be temporarily degraded!
The lithium-ion battery is protected against deep discharging
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 overheated battery, make sure to set the
machine’s On/Off switch 1 to off. Charge the battery and
allow it to cool down before restarting the machine. Other-
wise the battery can become damaged.
Preselecting the Orbital Stroke Rate
With the thumbwheel for preselection of the orbital stroke rate
5 , you can preselect the required orbital stroke rate, even dur-
ing operation.
The required stroke rate depends on the material and the
working conditions and can be determined through practical
testing.
Working Advice

Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as dur-
ing transport and storage, remove the battery
from the power tool. There is danger of injury when
unintentionally actuating the On/Off switch.

Wait until the machine has come to a standstill
before placing it down.
Note: Do not cover off the venting slots 2 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
oscillates up to 20000 times per minute at 2.8°. This allows
for precise work in narrow spaces.
Work with low and uniform application pres-
sure, 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

Use only undamaged saw blades that are in
perfect condition. Bent or dull saw blades can break,
negatively influence the cut, or lead to kickback.

When sawing light building materials, observe
the statutory provisions and the recommenda-
tions of the material suppliers.

Plunge cuts may only be applied to soft mate-
rials, such as wood, gypsum plaster boards,
etc.!
Before sawing with HCS 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.
