Changing the Cutting Disc (see figures B1 − B2)
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Do not activate the spindle lock (5) while the tool
u
spindle (22) is moving. The power tool may become
damaged if you do this.
Do not touch the cutting disc after use until it has
u
cooled. The cutting disc becomes very hot during use.
Only use cutting discs that match the specifications given in
this operating manual and that have been tested and marked
in accordance with EN 12413.
Use any intermediate layers provided with the cutting disc.
Place unused cutting discs in an enclosed container or their
original packaging. Store the cutting discs lying flat.
Removing the cutting disc
– Bring the power tool into the work position.
– Swivel the retracting blade guard (4) backwards as far as
possible.
– Turn the hexagon screw (25) using the hex key (12)
provided while pressing the spindle lock (5) until it en-
gages.
– Hold the spindle lock down and unscrew the hexagon
screw (25).
– Remove the washer (24) and the clamping flange (23).
– Remove the cutting disc (6).
Fitting the cutting disc
If required, clean all the parts you want to fit before installing
them.
– Place the new cutting disc on the tool spindle (22) such
that the sticker points away from the tool arm.
– Fit the clamping flange (23), the washer (24) and the
hexagon screw (25). Press the spindle lock (5) until it en-
gages and retighten the hexagon screw (25) by turning it
clockwise. (Tightening torque approx. 18–20 Nm)
– Slowly guide the retracting blade guard (4) all the way
down until the cutting disc is completely covered.
– Make sure that the retracting blade guard (4) is working
properly.
After fitting the cutting disc, check that the cutting disc is fit-
ted correctly and can turn freely before switching on the
power tool.
– Make sure that the cutting disc does not brush against the
retracting blade guard (4), the fixed protective guard
(20) or any other parts.
– Put the power tool into operation for approx. 30 seconds.
If there is substantial vibration, switch the power tool off
immediately, remove the cutting disc and then refit it.

– Press the tool arm down slightly by the handle (3) to re-
lease the transport safety lock (17).
– Pull the transport safety lock (17) all the way out.
– Slowly guide the tool arm upwards.
Note: Make sure that the transport safety lock is not pushed
in when working, otherwise the tool arm will not be able to
be swivelled to the required depth.
Locking the power tool (transport position)
– Guide the tool arm downwards until you can press the
transport safety lock (17) all the way in.
Further information about transporting (see "Transport",
page 20).
Setting the Mitre Angle (see figure D)
The mitre angle can be set between 0° and 45°.
Important settings are marked with corresponding markings
on the angle guide (7). The 0° and 45° positions are secured
by the respective end stop.
– Loosen the locking screws (16) on the angle guide using
the hex key (12) (8 mm) provided.
– Set the required angle and retighten both locking screws
(16).
Moving the Angle Guide (see figures D−E)
If you want to cut workpieces more than 140 mm wide, you
can move the angle guide (7) backwards.
– Completely unscrew the locking screws (16) using the
hex key provided (12) (8 mm).
– Move the angle guide (7) backwards by one or two holes
to the required distance.
– Set the required angle and retighten both locking screws
(16).
Clamping the workpiece
To ensure maximum safety while working, the workpiece
must always be firmly clamped.
Do not saw workpieces that are too small to clamp firmly.
Clamping the Workpiece (see figure E)
– Place the workpiece against the angle guide (7).
– Slide the locking spindle (8) against the workpiece and
clamp the workpiece in place using the spindle handle
(10).
Securing the Workpiece (cross section of max. 40 x 40
mm) (see figures F−H)
– Set the angle guide (7) to the standard 0° mitre/bevel
angle.
– Lift the workpiece support (15) slightly and slide it
through the slot in the angle guide.
– Hang the hook of the workpiece support in the opening of
the clamping jaw (14).
