Changing the Tool
 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.
 Wear protective gloves when changing appli-
cation tools/accessories. Contact with the applica-
tion tool/accessory can lead to injuries.
Mounting/Replacing the
Application Tool/Accessory
If required, remove an already mounted application
tool/accessory.
For removing the application tool/accessory, loosen the
screw 11 with the hex key 12 and remove the application
tool/accessory.
Insert the supplied adapter by allowing the smooth side of the
adapter to engage on the cams of the tool holder 8 (see fig-
ure on the graphics). Mount the application tool/accessory
on the adapter at any position.
Fasten the application tool/accessory with bolt 11. Tighten
the bolt with hex key 12 until the spring washer of the bolt
faces flush against the application tool/accessory.
 Check the tight seating of the application
tool/accessory. Incorrect or not securely fastened
application tools/accessories can come loose during
operation and pose a hazard.
Mounting/Replacing a Sanding Sheet
on the Sanding Plate
The sanding plate 10 is fitted with Velcro backing for quick
and easy fastening of sanding sheets with Velcro adhesion.
Before attaching the sanding sheet 13, free the Velcro back-
ing of the sanding plate 10 from any debris by tapping
against it in order to enable optimum adhesion.
Position the sanding sheet 13 flush alongside one edge of the
sanding plate 10, then lay the sanding sheet onto the sanding
plate and press firmly.
To ensure optimum dust extraction, pay attention that the
punched holes in the sanding sheet match with the holes in the
sanding plate.
To remove the sanding sheet 13, grasp it at one of the tips
and pull it off from the sanding plate 10.
Sanding accessories, such as fleece pads/polishing cloth
pads, are attached to the sanding plate in the same manner.

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.
Insert the charged battery 2 into the handle until it can be felt
to engage and faces flush against the handle.
Switching On and Off
To start the machine, push the On/Off switch 5 forward 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.
To save energy, only switch the power tool on when using it.
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 5 to off. Charge the battery and
allow it to cool down before restarting the machine. Other-
wise the battery can become damaged.
