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 hous-
ing.
– Clean the saw blade 20 and all clamping
parts to be assembled.
– Tilt back the retracting blade guard 11 and
hold firmly.
– Place the saw blade 20 on to the mounting
flange 21. The cutting direction of the teeth
(direction or arrow on saw blade) and the di-
rection-of-rotation arrow on the blade guard
15 must correspond.
– Mount the clamping flange 19 and screw in
the clamping bolt 18 turning in rotation di-
rection . Observe correct mounting posi-
tion of mounting flange 21 and clamping
flange 19.
– Press the spindle lock button 4 and keep it
pressed.
– With the Allen key 6, tighten the clamping
bolt 18 turning in rotation direction
tightening torque is between 6–9 Nm, which
corresponds to hand tight plus ¼ turn.
Dust/Chip Extraction (see figures B
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. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions 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
containing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.

Note: While sawing, always use the deflection
tube 24 or the dust/chip box 25 so that you will
not be hit by thrown about chips.
The deflection tube 24 can be used with or with-
out dust/chip extraction. Depending on the ap-
plication, turn the deflection tube 24 in such a
manner that you are not hit by chips and insert
it firmly into the sawdust ejector 16.
External Dust Extraction (see figure B)
Mount the vacuum hose 23 (accessory) on to
the saw dust ejector 16. Connect the vacuum
hose 23 to a vacuum cleaner (accessory). 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 re-
ceptacle of a Bosch all-purpose vacuum cleaner
with remote starting control. The vacuum clean-
er starts automatically when the machine is
switched on.
The vacuum cleaner must be suitable for the ma-
terial being worked.
. The
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.

Integrated Dust Extraction (see figures C–E)
For smaller jobs, the dust/chip box 25 can be
used with the slider 26 shut. For larger jobs, the
slider 26 should be open so that the chips can
fall out.
Insert the dust/chip box 25 firmly into the chip
ejector 16.
Empty the dust/chip box 25 in time to maintain
optimum efficiency.
To empty the dust/chip box 25, pull it off of the
sawdust ejector 16. Press the slider 26 upward,
turn the dust/chip box 25 aside and empty it.
Before reattaching, clean the connection sleeve
of the dust/chip box 25.
