Occasionally clean the ventilation slots on the battery using a
soft brush that is clean and dry.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
Assembly
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
Changing/fitting base plate and foam pad (see
figures A1− A2)
Unscrew the 4 screws (11) completely.
Pull the base plate away from the four pivoting feet (7).
Place the replacement pad on the four pivoting feet (7) and
push the pivoting feet into the recess (8).
Position the foam pad.
Secure both parts of the pad (base plate and foam pad) in
place with the screws (11).
Do not remove any hard components when changing the
foam pad.
Changing the sanding sheet
Remove dirt and dust from the sanding plate , e.g. with a
brush, before attaching a new sanding sheet.
To ensure optimum dust extraction, make sure that the
punched holes in the sanding sheet are aligned with the
drilled holes in the sanding plate.
Sanding sheets with hook-and-loop backing (see
figure B)
If the sanding plate is fitted with a hook-and-loop fastening,
sanding sheets with a hook-and-loop backing can be secured
quickly and easily.
Tap the hook-and-loop fastening of the sanding plate before
fitting the sanding sheet (17) to facilitate maximum adhe-
sion.
Position the sanding sheet (17) so that it is flush with one
side of the sanding plate , then place the sanding sheet on
the sanding plate and press it on firmly.
To remove the sanding sheet (17), take hold of it by a corner
and pull it away from the sanding plate .
Dust/Chip Extraction
The dust from materials such as lead paint, certain types of
wood and minerals can be harmful to human health. Touch-
ing or breathing in this dust can trigger allergic reactions
and/or cause respiratory illnesses in the user or in people in
the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.

– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Self-generated dust extraction with dust bag
(see figures F–H)
Place and move the complete dust bag (2) onto the extrac-
tion outlet (21) until it lines up precisely with the power tool.
To empty the dust bag(22), pull the complete dust bag (2)
away from the extraction outlet (21). Unscrew the adapter
(23) from the dust bag (22)
Note: Empty the dust bag (22) in good time to ensure op-
timum dust extraction.
When working vertical surfaces, hold the power tool in such
a manner that the dust bag (2) faces downward.
External dust extraction (see figure I)
Fit a dust extraction hose (24) onto the extraction outlet
(21).
Connect the dust extraction hose (24) to an extractor. You
will find an overview of connecting to various dust extractors
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.
When working on vertical surfaces, hold the power tool with
the dust extraction hose facing downwards.
Operation
Starting Operation
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, press the on/off switch (1).
To switch off the power tool, press the on/off switch (1)
again.
Preselecting the orbital stroke rate
You can even preselect the orbital stroke rate during opera-
tion using the necessary orbital stroke rate preselection
thumbwheel (6).
1–2 Low orbital stroke rate
3–4 Medium orbital stroke rate
5–6 High orbital stroke rate
The required orbital stroke rate is dependent on the material
and the work conditions and can be determined using prac-
tical tests.
