Assembly
Mounting/Replacing the Saw Blade
 Before any work on the machine itself, pull the mains
plug.
 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 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 23 turning
in rotation direction .
– Tilt back the retracting blade guard 11 and hold firmly.
– Remove the mounting flange 22 and the saw blade 21 from
the saw spindle 19.
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 21 and all clamping parts to be assem-
bled.
– Tilt back the retracting blade guard 11 and hold firmly.
Bosch Power Tools
– Place the saw blade 21 on the clamping flange 20. The cut-
ting direction of the teeth (arrow direction on saw blade)
and the rotation direction arrow on the blade guard 17
must match.
– Attach the mounting flange 22 and screw in the clamping
bolt 23 in rotation direction . Ensure that the mounting
flange 22 and clamping flange 20 are installed in the cor-
rect position.
– Press the spindle lock button 5 and keep it pressed.
– With the hex key 3, tighten the clamping bolt 23 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 machine itself, pull the mains
plug.
 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 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. Dusts can
easily ignite.
External Dust Extraction
Mount the vacuum hose 26 (accessory) on to the chip ejector
16. Connect the vacuum hose 26 to a vacuum cleaner (acces-
sory). An overview for connecting to various vacuum cleaners
can be found at the end of this manual.
The machine can be plugged directly into the receptacle of a
Bosch all-purpose vacuum cleaner with remote starting con-
trol. The vacuum cleaner starts automatically when the ma-
chine is switched on.
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.
Integrated Dust Extraction with Dust Bag
For smaller jobs, a dust bag (accessory) can be mounted. In-
sert the dust bag sleeve firmly into the saw dust ejector 16.
Empty the dust bag at regular intervals to maintain optimum
dust collection.
