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 Allen key 11, unscrew the clamping bolt 20 turn-
ing in rotation direction .
– Tilt back the retracting blade guard 13 and hold firmly.
– Remove the clamping flange 21 and the saw blade 22 from
the saw spindle 24.
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 22 and all clamping parts to be assem-
bled.
– Tilt back the retracting blade guard 13 and hold firmly.
– Place the saw blade 22 on to the mounting flange 23. The
cutting direction of the teeth (direction or arrow on saw
blade) and the direction-of-rotation arrow on the blade
guard 18 must correspond.
Bosch Power Tools
– Mount the clamping flange 21 and screw in the clamping
bolt 20 turning in rotation direction
mounting position of mounting flange 23 and clamping
flange 21.
– Press the spindle lock button 5 and keep it pressed.
– With the Allen key 11, tighten the clamping bolt 20 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 suita-
ble 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.
Mounting the Extraction Adapter (see figure B)
Attach the extraction adapter 25 onto the sawdust ejector 17
until it latches. A vacuum hose with a diameter of 35 mm can
be connected to the extraction adapter 25.
The extraction adapter may not be mounted when no
external dust extraction is connected. Otherwise the ex-
traction channel can become clogged.
Do not connect a dust bag to the extraction adapter.
Otherwise the extraction system can become clogged.
To ensure optimum extraction, the extraction adapter 25
must be cleaned regularly.
External Dust Extraction
Connect the vacuum hose 31 to a vacuum cleaner (accesso-
ry). 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.
