The dust/chip extraction system can be blocked by dust,
chips or fragments of the workpiece.
– Switch the power tool off and pull the mains plug out of
the socket.
– Wait until the saw blade has come to a complete stop.
– Determine the cause of the blockage and eliminate it.
External Dust Extraction
You can also attach a dust extraction hose (35 mm dia-
meter) to the chip ejector (13) for extraction.
– Connect the dust extraction hose to the chip ejector (13).
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 C1−C4)
Pull the plug out of the socket before carrying out any
u
work on the power tool.
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.
– Turn the hex socket screw (36) using the hex key (35)
while pressing the spindle lock (29) until it engages.
– Press and hold the spindle lock (29) and loosen the
screw (36) by turning it clockwise (left-hand thread).
– Remove the clamping flange (37).
– Push the locking switch (17) and swivel the retracting
blade guard (19) back as far as it will go.
– Hold the retracting blade guard in this position and re-
move the saw blade (39).
– 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.
– Push the locking switch (17), swivel the retracting blade
guard (19) back as far as it will go and hold it in this posi-
tion.
– Place the new saw blade on the inner clamping
flange (38).

Transport Safety Lock (see figure D)
The transport safety lock (30) makes it easier to handle the
power tool when transporting it to various working locations.
Unlocking the power tool (work position)
– Press the tool arm down slightly by the handle (16) to re-
lease the transport safety lock (30).
– Pull the transport safety lock (30) all the way out.
– Slowly guide the tool arm upwards.
Locking the power tool (transport position)
– Loosen the locking screw (11) if it is clamping the slide
device (12) in place. Pull the tool arm fully forward and
tighten the locking screw again to lock the slide device.
– To lock the saw table (22) in place, tighten the locking
knob (25).
– Push the locking switch (17) and slowly guide the tool
arm downwards using the handle (16).
– Guide the tool arm downwards until you can press the
transport safety lock (30) all the way in.
The tool arm is now securely locked and ready for transport-
ation.
Preparing for operation
Moving the fence (see figure E)
You have to move the adjustable fence (6) to saw bevel
angles.
– Loosen the locking screw (40) using the hex key (35)
provided.
Both external fastening screws must not be loosened.
– Pull the adjustable fence (6) all the way out.
– Re-tighten the locking screw (40).
After sawing the bevel angles, slide the adjustable fence (6)
back again (loosen the locking screw (40); slide the fence
(6) completely inward; retighten the locking screw).
Extending the saw table (see figure F)
The free end of long workpieces must have something
placed underneath it or be supported.
The saw table can be extended left and right using the saw
table extensions (3).
– Loosen the clamping screw (2).
– Pull out the saw table extension (3) to the required
length.
– Retighten the clamping screw (2) to fix the saw table ex-
