Items included
Carefully remove all parts included in the delivery from their
packaging.
Remove all packing material from the power tool and the ac-
cessories provided.
Check to ensure that all the parts listed below have been
supplied before using the power tool for the first time:
– Cut-off grinder with cutting disc fitted
– Hex key (12)
Note: Check the power tool for possible damage.
Before continuing to use the power tool, carefully check that
all protective devices or slightly damaged parts are working
perfectly and according to specifications. Check that the
moving parts are working perfectly and without jamming;
check whether any parts are damaged. All parts must be fit-
ted correctly and all the conditions necessary to ensure
smooth operation must be met.
If the protective devices or any parts become damaged, you
must have them properly repaired or replaced by an author-
ised service centre.
Stationary or flexible mounting
To ensure safe handling, the power tool must be
u
mounted on a flat, stable work surface (e.g. work
bench) before use.
Mounting on a work surface (see figure A)
– Use suitable screw fasteners to secure the power tool to
the work surface. Use the holes (11) to do this.
Flexible installation (not recommended)
In exceptional circumstances, if it is not possible to securely
mount the power tool on a work surface, you can improvise
by placing the feet of the base plate (13) on an appropriate
base (e.g. workbench, flat ground, etc.), without screwing
down the power tool.
Changing the Tool (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.

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.
Operation
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Transport Safety Lock (see figure C)

lease the transport safety lock (17).
– Pull the transport safety lock (17) all the way out.
