The vibration level given in this information sheet has been
measured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with anoth-
er. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or insertion tools or is
poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working
period.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work pat-
terns.
Assembly
Battery Charging
 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 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 19 is equipped with two locking levels that should
prevent the battery from falling out when pushing the battery
unlocking button 26 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 19, press the battery unlocking button
26 and pull the battery out of the power tool toward the rear.
Do not exert any force.
Battery Charge-control Indication (see figure F)
The three green LEDs of the battery charge-control indicator
33 indicate the charge condition of the battery 19. For safety
reasons, it is only possible to check the status of the charge
condition when the machine is at a standstill.
Press button 32 to indicate the charge condition. This is also
possible when the battery 19 is removed.
When no LED lights up after pushing button 32, then the bat-
tery is defective and must be replaced.
Mounting/Replacing the Saw Blade
 Before any work on the power tool, remove the battery.
 When mounting the saw blade, wear protective gloves.
Danger of injury when touching the saw blade.
 Only use saw blades that correspond with the charac-
teristic data given in the operating instructions.
 Do not under any circumstances use grinding discs as
the cutting tool.
