Operating Modes - Bosch PKS 55 Notice Originale

18 | English
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
Only use saw blades the maximum permitted speed of
u
which is higher than the no-load speed of the power
tool.
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 (4).
Do not press the spindle lock button (4) while the saw
u
spindle is moving. The power tool may become damaged
if you do this.
– Use the hex key (6) to undo the clamping bolt (18) in ro-
tational direction ➊.
– Swing the retracting blade guard (11) back and hold on
to it firmly.
– Remove the clamping flange (19) and the saw blade (20)
from the saw spindle (22).
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 (11) back and hold on
to it firmly.
– Place the saw blade (20) on the mounting flange (21).
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 (15).
– Attach the clamping flange (19) and screw in the clamp-
ing bolt (18) in rotational direction ➋. Ensure that the
mounting flange (21) and clamping flange (19) are in-
stalled in the correct position.
– Press and hold the spindle lock button (4).
– Use the hex key (6) to tighten the clamping bolt (18) in
rotational direction ➋. The tightening torque should be
6–9 Nm, which corresponds to hand-tight plus ¼ turn.
Dust/chip extraction (see figures B–E)
Pull the plug out of the socket before carrying out any
u
work on the power tool.
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.
Note: Always use the deflection tube (24) or the dust/chip
box (25) when sawing to avoid being hit by flying chips.
The deflection tube (24) can be used either with or without
the dust/chip extractor attached. Turn the deflection tube
away from you so that you will not be hit by the chips (posi-
tion will vary depending on the application) and firmly con-
nect it to the chip ejector (16).
External dust extraction (see figure B)
Connect an extraction hose (23) (accessory) to the chip
ejector (16). Connect the extraction hose (23) to a dust ex-
tractor (accessory). You will find an overview of connecting
to various dust extractors at the end of these operating in-
structions.
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.
Self-generated dust extraction (see figures C – E)
For smaller jobs, the dust/chip box (25) can be used with
the slider (26) closed. For larger jobs, you should leave the
slider 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) at regular intervals to maintain
efficiency.
To empty the dust/chip box (25), pull it out of the chip
ejector (16). Push the slider (26) upwards, turn the dust/
chip box (25) onto its side and empty it.
Clean the connector of the dust/chip box (25) before insert-
ing it again.
Operation

Pull the plug out of the socket before carrying out any
u
work on the power tool.
Setting the cutting depth (see figure F)
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 (27). For a smaller cutting depth,
pull the saw away from the base plate (12); for a larger cut-
