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 a dust bag (57) (accessory).
– Attach the dust bag (57) to the chip ejector (2).
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 chip ejector (2) for extraction.
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

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.
Assembly with hex socket screw (see figures D1−D4)
Removing the saw blade
– Bring the power tool into the work position.

– Turn the hex socket screw (59) using the hex key (44)
while pressing the spindle lock (58) until it engages.
– Press and hold the spindle lock (58) and loosen the
screw (59) by turning it clockwise (left-hand thread).
– Remove the clamping flange (60).
– Swivel the retracting blade guard (12) backwards as far
as possible.
– Hold the retracting blade guard in this position and re-
move the saw blade (13).
– 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 (12) to the back and
hold it in this position.
– Place the new saw blade on the inner clamping
flange (62).
– Fit the clamping flange (60) and the hex socket
screw (59). Press the spindle lock (58) until it engages
and tighten the hex socket screw by turning it anticlock-
wise.
– Slowly push the retracting blade guard back down.
Assembly with SDS bolt (see figure E)
For bevel cuts when using the SDS bolt (63), before
u
sawing, first make sure that the SDS bolt cannot come
into contact with the surface of the workpiece at any
time by making a suitable adjustment to the depth
stop (35). This prevents damage to the SDS bolt and/or
the workpiece.
Removing the saw blade
– Bring the power tool into the work position.
– Press and hold the spindle lock (58) and unscrew the
SDS bolt (63) by turning it clockwise (left-hand thread).
– Remove the clamping flange (60).
– Swivel the retracting blade guard (12) backwards as far
as possible.
– Hold the retracting blade guard in this position and re-
move the saw blade (13).
– 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 to be fitted before installing
them.
– Swivel the retracting blade guard (12) backwards. Hold
the retracting blade guard in this position.
– Place the new saw blade onto the interior clamping flange
(62).
