Assembly
 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
Battery Charging (see figure A)
 Use only the battery chargers listed on the accessories
page. Only these battery chargers are matched to the lith-
ium ion battery of your power tool.
Note: The battery is supplied partially charged. To ensure full
capacity of the battery, completely charge the battery in the
battery charger before using your power tool for the first time.
The lithium ion battery can be charged at any time without re-
ducing its service life. Interrupting the charging procedure
does not damage the battery.
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.
 Do not continue to press the On/Off switch after the
machine has been automatically switched off. The bat-
tery can be damaged.
To remove the battery 4, press the battery unlocking button 5
and pull the battery upward out of the power tool. Do not ex-
ert any force.
The battery is equipped with a NTC temperature control
which allows charging only within a temperature range of be-
tween 0 °C and 45 °C. A long battery service life is achieved
in this manner.
Observe the notes for disposal.
Replacing/Inserting the Saw Blade
 When mounting the saw blade, wear protective gloves.
Danger of injury when touching the saw blade.
Selecting a Saw Blade
An overview of recommended saw blades can be found at the
end of these instructions. Use only T-shank saw blades or saw
blades with 1/4" universal shank (U-shank). The saw blade
should not be longer than required for the intended cut.
Use a thin saw blade for narrow curve cuts.
Inserting the Saw Blade (see figure B)
 Clean the shank of the saw blade before inserting it. An
unclean shank cannot be fastened securely.
If required, remove the dust cover 11 (see "Dust Cover").
Push the saw blade holder 17 upward in the direction of the
arrow. Insert the saw blade 14 (teeth in cutting direction) to
the stop into the saw blade holder.
While inserting the saw blade, pay attention that the back of the
saw blade is positioned in the groove of the guide roller 12.
 Check the tight seating of the saw blade. A loose saw
blade can fall out and lead to injuries.

Removing the Saw Blade (see figure C)
Push the saw blade holder 17 upward in the direction of the
arrow and remove the saw blade 14.
Saw Blade Storage (see figure D)
Up to six saw blades with lengths to 110 mm can be stored in
the saw blade storage 8. Insert the saw blades with the T-shank
into the recess of the saw blade storage intended for this. Up to
three saw blades can be placed on top of each other.
Shut the saw blade storage and slide it to the stop into the
opening of the base plate 9.
Splinter Guard (see figure E)
The splinter guard 20 (accessory) can prevent fraying of the
surface while sawing wood. The splinter guard can only be
used for certain saw blade types and only for cutting angles of
0°. When sawing with the splinter guard, the base plate 9
must not be moved back for cuts that are close to the edge.
Press the splinter guard 20 from below into the base plate 9
(with the notch facing upward as shown in the figure).
"Cut Control"
"Cut Control" enables precise guiding of the power tool along
a cutting line marked on the workpiece. The "Cut Control" kit
includes the viewing window 15 with cutting marks and the
base 13 for attachment to the power tool.
Attaching "Cut Control" to the Base Plate (see figure F)
Clamp the "Cut Control" 15 viewing window into the holders
of the base 13. Then, lightly press the base together and allow
it to engage into the lead 21 of the base plate 9.
Dust/Chip Extraction
 Dusts 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 dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suita-
ble for the material.
– 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
materials to be worked.
Dust Cover
Mount the dust cover 11 before connecting the machine to
the dust extraction.
Mount the dust cover 11 onto the machine in such a manner
that the centre holder engages on the contact protector 16 and
the two outer holders engage in the openings on the casing.
Remove the dust cover 11 for applications without dust ex-
traction as well as when performing mitre cuts. For this, push
the dust cover together at the two outer holders and pull it off
toward the front.
