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 4 and keep it pressed.
 The spindle lock button 4 may be actuated only when
the saw spindle is at a standstill. Otherwise, the power
tool can be damaged.
– With the Allen key 6, unscrew the clamping bolt 19 turning
in rotation direction .
– Tilt back the retracting blade guard 12 and hold firmly.
– Remove the clamping flange 20 and the saw blade 21 from
the saw spindle 23.
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 12 and hold firmly.
– Place the saw blade 21 on to the mounting flange 22. The
cutting direction of the teeth (direction or arrow on saw
blade) and the direction-of-rotation arrow on the blade
guard 17 must correspond.
Bosch Power Tools
– Mount the clamping flange 20 and screw in the clamping
bolt 19 turning in rotation direction . Observe correct
mounting position of mounting flange 22 and clamping
flange 20.
– Press the spindle lock button 4 and keep it pressed.
– With the Allen key 6, tighten the clamping bolt 19 turning
in rotation direction . The tightening torque is between
6–9 Nm, which corresponds to hand tight plus ¼ turn.
Adjusting the Riving Knife (see figure B–C)
 Before any work on the machine itself, pull the mains
plug.
 Always work with the riving knife, except when carry-
ing out plunge cuts. The riving knife prevents jamming of
the saw blade while sawing.
Adjustment is carried out at minimal cutting depth, see "Ad-
justing the Cutting Depth", page 18.
It is best to place the machine on the face side of the blade
guard 17.
Loosen the clamping lever 25, pull the saw away from the
base plate 14 and then tighten the clamping lever 25 again.
Loosen screw 24, adjust the riving knife 13 to the measure
shown in the figure and tighten screw 24 with a tightening
torque between 8–9 Nm.
Disassembly/Assembly of the Riving Knife
For disassembly of the riving knife 13, loosen screw 24 and
remove the riving knife 13.
For assembly, insert the riving knife 13 and tighten it with the
screw 24. Afterwards, check the adjustment of the riving
knife as described previously.
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.
Mounting the Extraction Adapter (see figure F)
Attach the extraction adapter 28 onto the sawdust ejector 16
until it latches. A vacuum hose with a diameter of 35 mm can
be connected to the extraction adapter 28.
 The extraction adapter may not be mounted when no
external dust extraction is connected. Otherwise the ex-
traction channel can become clogged.
