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 (21) and all the clamping elements
to be fitted.
– Swing the retracting blade guard (12) back and hold on
to it firmly.
– Place the saw blade (21) on the mounting flange (22).
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 (12).
– Attach the clamping flange (20) and screw in the clamp-
ing bolt in rotational direction ➋. Ensure that the mount-
ing flange (22) and clamping flange (20) are installed in
the correct position.
– Press and hold the spindle lock button (5).
– Use the hex key (18) to tighten the clamping bolt in rota-
tional direction ➋. The tightening torque should be
6−9 Nm, which corresponds to hand-tight plus ¼ turn.
Dust/chip extraction
The dust from materials such as lead paint, some 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.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– 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)
Push the dust extraction adapter (25) onto the chip ejector
(15) until it clicks into place.
A dust extraction hose with a diameter of 35 mm can be con-
nected to the dust extraction adapter (25).
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
(25) must be cleaned regularly.
External dust extraction
Connect the extraction hose (32) to a dust extractor (ac-
cessory). You will find an overview of connecting to various
dust extractors at the end of these operating instructions.
1 609 92A 4LP | (19.11.2018)
The power tool can be directly connected to the socket of a
Bosch all-purpose dust extractor with remote starter. This
dust extractor is started up automatically when the power
tool is switched on.
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.
Operation
Operating modes
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Setting the cutting depth (see figure C)
Adapt the cutting depth to the thickness of the work-
u
piece. A space of less than the height of one full tooth
should be visible under the workpiece.
Loosen the clamping lever (26). For a smaller cutting depth,
pull the saw away from the base plate (13); for a larger cut-
ting depth, push the saw towards the base plate (13). Adjust
the desired cutting depth at the cutting-depth scale.
Retighten the clamping lever (26).
If you are unable to fully adjust the cutting depth after
loosening the clamping lever (26), pull the clamping lever
(26) away from the saw and swivel it downwards. Loosen
the clamping lever (26) again. Repeat this process until the
required cutting depth can be set.
If you are unable to adequately fix the cutting depth after
tightening the clamping lever (26), pull the clamping lever
(26) away from the saw and swivel it upwards. Loosen the
clamping lever (26) again. Repeat this process until the cut-
ting depth is fixed.
Adjusting the mitre/bevel angle
We recommend that you place the power tool down on the
front side of the protective guard (16).
Loosen the clamping lever (8) and wing bolt . Swivel the saw
to the side. Set the required mitre/bevel angle on the scale
(6). Retighten the clamping lever (8) and wing bolt .
Note: When making mitre cuts, the cutting depth is less than
the value shown on the cutting depth scale (27).
Cut marks
The 0° cut mark (9) indicates the position of the saw blade
when making a right-angled cut. The 45° cut mark (10) indic-
ates the position of the saw blade when making a 45° cut –
when used without a guide rail.
Start-up
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
