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 battery 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 protec-
tive gloves. Danger of injury when touching the saw
blade.

Only use saw blades that correspond with the
characteristic data given in the operating
instructions.

Do not under any circumstances use grinding
discs as the cutting tool.
Removal of the Saw Blade
(see figure A)
For changing the cutting tool, it is best to place the machine
on the face side of the motor housing.
• Press the spindle lock button
5 and keep it pressed.

The spindle lock button 5 may be actuated
only when the saw spindle is at a standstill.
Otherwise, the power tool can be damaged.
• With the hex key 3 , unscrew the clamping bolt 25 turning
in rotation direction

.
• Tilt back the retracting blade guard 13 and hold firmly.
• Remove the clamping flange 24 and the saw blade 23
from the saw spindle 21 .
Mounting the Saw Blade (see figure A)
For changing the cutting tool, it is best to place the machine
on the face side of the motor housing.
• Clean the saw blade
23 and all clamping parts to be
assembled.
• Tilt back the retracting blade guard 13 and hold firmly.
• Place the saw blade 23 onto the mounting flange 22 . The
cutting direction of the teeth (direction of arrow on the saw
blade) and the direction-of-rotation arrow on the retract-
ing blade guard 13 must correspond.
• Mount the clamping flange 24 and screw in the clamping
bolt 25 turning in rotation direction

. Observe correct
mounting position of mounting flange 22 and clamping
flange 24 .
• Press the spindle lock button 5 and keep it pressed.
• With the hex key 3 , tighten the clamping bolt 25 turning
in rotation direction

. The tightening torque is between
6–9 Nm, which corresponds to hand tight plus ¼ turn.
Dust/Chip Extraction

Before any work on the power tool, remove
the battery.
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 carci-
nogenic, especially in connection with wood-treatment addi-
tives (chromate, wood preservative). Materials containing
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.
