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.
Inserting/changing the saw blade
When fitting or changing the saw blade, wear protect-
u
ive gloves. Blades are sharp and can become hot when
used for prolonged periods of time.
Selecting the saw blade
You will find an overview of recommended saw blades at the
end of these operating instructions. Only use saw blades
with single lug shank (T shank). The saw blade should not be
longer than required for the intended cut.
Use a narrow saw blade when sawing tight curves.
Inserting the saw blade and adjusting the saw blade
guide (see figures A–B)
Clean the shaft on the saw blade before inserting it.
u
A dirty shaft cannot be securely fixed in place.
If necessary, remove the hood (28).
Pull the SDS lever (19) forward as far as it will go and hold it
there. Push the saw blade (16), with the teeth in the cutting
direction, into the saw blade receptacle (18) until it clicks
into place.
Make sure when inserting the saw blade that the saw blade is
in between the jaws of the saw blade guide (15).
Check that the saw blade is seated securely. A loose
u
saw blade can fall out and lead to injuries.
For a good cutting result, the jaws of the saw blade
guide (15) should be as close as possible to the saw
blade (16) without clamping the saw blade. To adjust the
distance to the thickness of the saw blade, you can adjust a
jaw on the saw blade guide.
Insert the hex key (26) into the adjustment opening (24) in
the base plate. Turn the hex key as indicated by the marking
next to the adjustment opening (clockwise to shorten the
distance, anticlockwise to increase the distance). Make sure
that the saw blade can still turn freely.
Removing the saw blade (see figure C)
Pull the SDS lever (19) all the way forwards and remove the
saw blade (16).
Anti-splinter guard (see figure D)
The anti-splinter guard (27) (accessory) can prevent splin-
tering of the surface while sawing wood. The anti-splinter
guard can only be used with certain saw blade types.
Slide the anti-splinter guard (27) into the base plate (13)
from the front.

Dust/Chip Extraction

The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
1 609 92A 6Y3 | (27.07.2022)
Touching or breathing in this dust can trigger allergic reac-
tions 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.
Hood (see figure E)
Fit the hood (28) before you connect the power tool to the
dust extraction system.
Position the hood (28) (accessory) with the bracket on one
side of the safety guard (17). Press down the hood on the
other side of the safety guard so that the bracket locks into
place on the safety guard.
Remove the hood (28) when working without a dust extrac-
tion system. To do this, hold the hood on one side and pull it
forwards off the safety guard (17).
Connecting the dust extraction (see figures F–H)
Remove the battery (10) before you use or remove the ex-
traction outlet.
Fit the extraction outlet (29) in the recesses of the base
plate (13).
Connect a dust extraction hose (30) (accessory) to the ex-
traction outlet (29). Connect the dust extraction hose (30)
to a dust extractor (accessory).
You will find an overview of connecting to various dust ex-
tractors at the end of these operating instructions.
Switch off the sawdust blower device when you have con-
nected the dust extraction system.
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.
To remove the extraction outlet (29) again, press the release
button (12) and pull the extraction outlet out of the base
plate (13).
