The specifications apply to a rated voltage [U] of 220 V. These spe-
cifications may vary at different voltages and in country-specific mod-
els.
Noise information
Noise emission values determined according to
EN 62841-1.
Typically the A-weighted noise level of the power tool is:
Sound pressure level 100 dB(A); sound power level
113 dB(A). Uncertainty K = 3 dB.
Wear hearing protection
The noise emission value given in these instructions has
been measured in accordance with a standardised measur-
ing procedure and may be used to compare power tools. It
may also be used for a preliminary estimation of noise emis-
sions.
The noise emission value given represents the main applica-
tions of the power tool. However, if the power tool is used
for other applications, with different application tools or is
poorly maintained, the noise emission value may differ. This
may significantly increase noise emissions over the total
working period.
To estimate noise emissions accurately, the times when the
tool is switched off, or when it is running but not actually be-
ing used, should also be taken into account. This may signi-
ficantly reduce noise emissions over the total working
period.
Mounting
Avoid starting the power tool unintentionally. The
u
mains plug must not be connected to the power supply
during assembly or when carrying out any kind of
work on the power tool.
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:
– Metal cut-off saw with mounted saw blade
– Hex key/cross-headed screwdriver (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 a suitable screwed connection to secure the power
tool to the work surface. Use the holes (23) to do this.
Flexible installation (not recommended)
If, in exceptional circumstances, it is not possible to securely
mount the power tool on a work surface, you can improvise
by placing the feet of the saw table (25) on an appropriate
base (e.g. workbench, flat ground, etc.), without screwing
down the power tool.
Changing the saw blade (see figures B1−B4)
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Do not activate the spindle lock (3) while the tool
u
spindle is moving. The power tool may become damaged
if you do this.
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 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.
– Loosen the fastening screw (26) (by approx. two turns)
using the cross-headed screwdriver (12).
Do not unscrew the screw completely.
– Loosen the fastening screw (27) (by approx. six turns)
using the cross-headed screwdriver (12).
Do not unscrew the screw completely.
– Press the locking lever (1) and swivel the retracting blade
guard (4) upwards as far as possible.
