u
the power tool.
Wear protective gloves when fitting the saw blade.
u
Danger of injury when touching the saw blade.
Only use saw blades that match the specifications
u
given in this operating manual and that are tested and
marked in accordance with EN 847-1
The permitted speed of the application tool must be at
u
least equal to the maximum speed marked on the
power tool. If accessories run faster than their rated
speed, they may break and fly off.
Do not use abrasive wheels as the application tool un-
u
der any circumstances.
Selecting the saw blade
You will find an overview of recommended saw blades at the
end of these operating instructions.
Removing the saw blade (see figure A)
To change tools, we recommend that you place the power
tool down on the front side of the motor housing.
– Press and hold the spindle lock button (14).
Do not press the spindle lock button (14) while the
u
saw spindle is moving. The power tool may become
damaged if this happens.
– Use the hex key (16) to undo the clamping bolt (22) in ro-
tational direction ➊.
– Swing the retracting blade guard (7) back and hold on to
it firmly.
– Remove the clamping flange (21) and the saw blade (20)
from the saw spindle (18).
Fitting the saw blade (see figure A)
To change tools, we recommend that you place the power
tool down on the front side of the motor housing.
– Clean the saw blade (20) and all the clamping elements
to be fitted.
– Swing the retracting blade guard (7) back and hold on to
it firmly.
– Place the saw blade (20) on the mounting flange (19).
The cutting direction of the teeth (direction of the arrow
on the saw blade) must match the rotational direction of
the arrow on the protective guard (7).
Bosch Power Tools
– Attach the clamping flange (21) and screw in the clamp-
ing bolt (22) in rotational direction ➋. Ensure that the
mounting flange (19) and clamping flange (21) are in-
stalled in the correct position.
– Press and hold the spindle lock button (14).
Capacity
– Use the hex key (16) to tighten the clamping bolt (22) in
≥ 66%
rotational direction ➋. The tightening torque should be
≥ 33%
6–9 Nm, which corresponds to hand-tight plus ¼ turn or
<33% three graduation marks of the marking (23) on the pro-
tective guard (4).

Dust/chip extraction
The dust from materials such as lead paint, certain types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– To achieve a high level of dust extraction, use the dust ex-
tractor GAS 25/GAS 50/GAS 50 M for wood or GAS 50
MS for wood and/or mineral dust together with this power
tool.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Fitting the dust extraction adapter (see figure B)
Fasten the dust extraction adapter (26) to the base plate (6)
using the fastening screw (25).
A dust extraction hose with a diameter of 35 mm can be con-
nected to the dust extraction adapter (26).
The dust extraction adapter must only be fitted if an
u
external dust extraction system is connected. Other-
wise the extraction duct can become clogged.
No dust bags should be connected to the dust extrac-
u
tion adapter. Otherwise the extraction system can be-
come clogged.
To ensure optimum extraction, the dust extraction adapter
(26) must be cleaned regularly.
External dust extraction
Connect the dust extraction hose (27) to a dust extractor
(accessory). You will find an overview of how to connect to
various dust extractors at the end of these operating instruc-
tions.
The dust extractor must be suitable for the material being
worked.
When extracting dry dust that is especially detrimental to
health or carcinogenic, use a special dust extractor.
