Assembly
Mounting/Replacing the Saw Blade
Before any work on the machine itself, pull
the mains plug.
When mounting the saw blade, wear protec-
tive gloves. Danger of injury when touching the
saw blade.
Only use saw blades that correspond with the
characteristic 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)
• Tilt back the retracting blade guard 11 and hold
firmly.
• Lock the clamping flange 20 using an open-end
spanner 19 (size 22 mm) or position the saw blade
21 onto a piece of wood.
• Unscrew the clamping bolt 18 with the Allen key 3.
• Remove the clamping flange 20 and the saw blade
21 from the motor spindle 23.
Mounting the Saw Blade (see figure A)
• Clean the saw blade 21 and all clamping parts to be
assembled.
• Tilt back the retracting blade guard 11 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 16 must correspond.

directives 89/336/EEC,
English–5
• Mount the clamping flange 20 and screw in the
clamping bolt 18. Observe correct mounting posi-
tion of mounting flange 22 and clamping flange 20.
• Lock the clamping flange 20 using an open-end
spanner 19 (size 22 mm) or position the saw blade
21 onto a piece of wood.
• Tighten the clamping bolt 18 with the Allen key 3.
The tightening torque is between 6–9 Nm, which
corresponds to hand tight plus ¼ turn.
Adjusting the Riving Knife
(see figure B)
Before any work on the machine itself, pull
the mains plug.
Always work with the riving knife, except
when carrying out plunge cuts. The riving knife
prevents jamming of the saw blade while sawing.
Adjustment is carried out at maximum cutting depth,
see Section "Adjusting the Cutting Depth".
Loosen screw 24, adjust the riving knife 12 to the
measure shown in the figure and tighten the screw 24
again.

Dust/Chip Extraction

Before any work on the machine itself, pull
the mains plug.
External Dust Extraction
Mount the vacuum hose 29 (accessory) on to the saw
dust ejector 17. Connect the vacuum hose 29 to a vac-
uum 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 recepta-
cle of a Bosch all-purpose vacuum cleaner with remote
starting control. The vacuum cleaner starts automati-
cally when the machine 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)
mounted. Insert the dust bag sleeve firmly into the saw
dust ejector 17. Empty the dust bag at regular intervals
to maintain optimum dust collection.
