Bosch Power Tools
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
22
and all clamping
parts to be assembled.
– 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 di-
rection-of-rotation arrow on the blade guard
18
must correspond.
– Mount the clamping flange
21
and screw in
the clamping bolt
20
turning in rotation di-
rection
o
. Observe correct mounting posi-
tion of mounting flange
23
and clamping
flange
21
.
– Press the spindle lock button
5
and keep it
pressed.
– With the Allen key
7
, tighten the clamping
bolt
20
turning in rotation direction
o
. The
tightening torque is between 6–9 Nm, which
corresponds to hand tight plus ¼ turn.
Dust/Chip Extraction
f
Before any work on the machine itself, pull
the mains plug.
f
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.
Mounting the Extraction Adapter
(see figure B)
Attach the extraction adapter
25
onto the saw-
dust ejector
17
until it latches. A vacuum hose
with a diameter of 35 mm can be connected to
the extraction adapter
25
.
f
The extraction adapter may not be mounted
when no external dust extraction is con-
nected.
Otherwise the extraction channel
can become clogged.
f
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 clean-
er (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.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
Operation
Operating Modes
f
Before any work on the machine itself, pull
the mains plug.
Adjusting the Cutting Depth (see figure C)
f
Adjust the cutting depth to the thickness of
the workpiece.
Less than a full tooth of the
blade teeth should be visible below the work-
piece.
