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

 Use only the chargers listed in the technical data. Only
these chargers are matched to the lithium-ion battery of
your power tool.
Note: The battery supplied is 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.
Observe the notes for disposal.
Removing the battery
The battery 3 is equipped with two locking levels that should
prevent the battery from falling out when pushing the battery
unlocking button 4 unintentionally. As long as the battery is
inserted in the power tool, it is held in position by means of a
spring.
To remove the battery 3, press the battery unlocking button 4
and pull the battery toward the rear out of the power tool. Do
not exert any force when doing this.
Battery Charge-control Indication (see figure A)
The three green LEDs of the battery charge-control indicator
18 indicate the charge condition of the battery 3. For safety
reasons, it is only possible to check the status of the charge
condition when the machine is at a standstill.
Press button 17 to indicate the charge condition. This is also
possible when the battery 3 is removed.

When no LED lights up after pushing button 17, then the bat-
tery is defective and must be replaced.
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.
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.
Insert the saw blade 10 into the stroke rod 19 until it latches.
The SDS lever 11 automatically snaps to the rear and the saw
blade is locked. Do not manually press the lever 11 toward
the rear, otherwise you could damage the machine.
While inserting the saw blade, pay attention that the back of
the saw blade is positioned in the groove of the guide roller 9.
 Check the tight seating of the saw blade. A loose saw
blade can fall out and lead to injuries.
Ejecting the Saw Blade (see figure C)
 When ejecting the saw blade, hold the machine in such
a manner that no persons or animals can be injured by
the ejected saw blade.
Turn the SDS lever 11 all the way forward in the direction in-
dicated by the arrow. The saw blade is released and ejected.

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 car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable
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.
 Prevent dust accumulation at the workplace. Dust can
easily ignite.
