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 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.
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.
Removing the battery (see figure A)
The battery 3 is equipped with two locking levels that should
prevent the battery from falling out when pushing the battery
unlocking button 17 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 but-
ton 17 and pull the battery upward out of the power tool.
Do not exert any force.

Dust/Chip Extraction

 Before any work on the power tool, remove the battery.
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-treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be worked by specialists.
Bosch Power Tools
– 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 mate-
rials to be worked.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
External Dust Extraction (see figure B)
– Insert a vacuum hose 18 (accessory) into the vacuum con-
nection 4. Connect the vacuum hose 18 to a vacuum clean-
er (accessory). An overview for connecting to a vacuum
cleaner can be found at the end of these instructions.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
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.
Selecting a Saw Blade
An overview of recommended saw blades can be found at the
end of this manual.
Removal of the Saw Blade (see figure C)
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 19 and keep it pressed.
 The spindle lock button 19 may be actuated only when
the saw spindle is at a standstill. Otherwise, the power
tool can be damaged.
– With the Allen key 24, unscrew the clamping bolt 23 turn-
ing in rotation direction .
– Tilt back the retracting blade guard 9 and hold firmly.
– Remove the clamping flange 22 and the saw blade 8 from
the saw spindle 20.
Mounting the Saw Blade (see figure C)
For changing the cutting tool, it is best to place the machine
on the face side of the motor housing.
– Clean the saw blade 8 and all clamping parts to be assem-
bled.
– Tilt back the retracting blade guard 9 and hold firmly.
– Place the saw blade 8 onto the mounting flange 21. 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 9 must correspond.
– Mount the clamping flange 22 and screw in the clamping
bolt 23 turning in rotation direction . Observe correct
mounting position of mounting flange 21 and clamping
flange 22.
