Dust/Chip Extraction - Bosch GCM 18V-216 D Professional Originalbetriebsanleitung

Assemble the saw stand properly before mounting the
u
power tool. Correct assembly is important to prevent the
risk of collapsing.
– Mount the power tool on the saw stand in the transport
position.
Flexible installation (not recommended) (see figure B3)
If, in exceptional circumstances, it is not possible to mount
the power tool on a flat and stable work surface, you can im-
provise by setting it up with the tilt protector.
Without the tilt protector, the power tool will not be
u
stable and can tip over especially when sawing max-
imum mitre and/or bevel angles.
– Rotate the tilt protector (18) inwards or outwards until
the power tool is positioned straight on the work surface.

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.
The dust/chip extraction system can be blocked by dust,
chips or fragments of the workpiece.
– Switch the power tool off and remove the battery.
– Wait until the saw blade has come to a complete stop.
– Determine the cause of the blockage and eliminate it.
Self-generated dust extraction (see figure C)
For basic chip collection, use the dust bag (37) provided.
– Turn the transport handle (3) so that it is vertical.
– Place the dust bag (37) onto the extraction adapter (50)
and turn so that the pin of the dust bag locks in place in
the recess of the extraction adapter.
During sawing, the dust bag must not come into contact with
moving tool components.
Always empty the dust bag in good time.
Check and clean the dust bag each time after using.
u
When sawing aluminium, remove the dust bag to avoid
u
the risk of fire.
External Dust Extraction
You can also attach a dust extraction hose (35 mm dia-
meter) to the extraction adapter (50) for extraction.
Bosch Power Tools
– Connect the dust extraction hose to the extraction
adapter (50).
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.
Changing the saw blade (see figures D1−D4)
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
Wear protective gloves when fitting the saw blade.
u
There is a risk of injury when touching the saw blade.
Only use saw blades that have a maximum permitted speed
higher than the no-load speed of the power tool.
Only use saw blades that match the specifications given in
this operating manual and that have been tested and marked
in accordance with EN 847-1.
Only use saw blades that are recommended by the power
tool manufacturer and are suitable for use on the material
you want to saw. This will prevent the saw teeth overheating
when sawing.
Removing the Saw Blade
– Bring the power tool into the work position.
– Swivel the retracting blade guard (10) to the back and
hold it in this position.
– Turn the hex socket screw (51) with the hex key
(6 mm) (43) and at the same time push the spindle
lock (31) until it engages.
– Keep holding the spindle lock (31) and loosen the hex
socket screw (51) by turning it clockwise (left-hand
thread).
– Remove the clamping flange (52).
– Remove the saw blade (30).
– Slowly push the retracting blade guard back down.
Fitting the saw blade
When fitting the saw blade, make sure that the cutting
u
direction of the teeth (arrow direction on the saw
blade) matches the direction of the arrow on the pro-
tective guard.
If required, clean all the parts you want to fit before installing
them.
– Swivel the retracting blade guard (10) to the back and
hold it in this position.
– Place the new saw blade on the inner clamping
flange (53).
– Fit the clamping flange (52) and the hex socket
screw (51). Press the spindle lock (31) until it engages
and tighten the hex socket screw by turning it anticlock-
wise.
– Slowly push the retracting blade guard back down.
