The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-specific models.
The appliance meets IEC 61000-3-11 requirements and is subject to conditional connection. The appliance can lead to occa-
sional voltage fluctuations under unfavorable power conditions. The impedance of this appliance is set as Z

Noise/Vibration Information
Noise emission values determined according to
EN 60745-2-3.
Typically the A-weighted noise level of the power tool are: 93
dB(A); sound power level 104 dB(A). Uncertainty K = 3 dB.
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K

The vibration level given in these instructions has been
measured in accordance with a standardised measuring pro-
cedure and may be used to compare power tools. It can also
be used for a preliminary estimation of exposure to vibra-
tion.
The stated vibration level applies to the main applications of
the power tool. However, if the power tool is used for differ-
ent applications, with different application tools or poorly
maintained, the vibration level may differ. This can signific-
antly increase the exposure to vibration over the total work-
ing period.
To estimate the exposure to vibration accurately, the times
when the tool is switched off or when it is running but not ac-
tually being used should also be taken into account. This can
significantly reduce the exposure to vibration over the total
working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping the hands warm,
and organising workflows correctly.
Fitting
Fitting protective equipment
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Note: If the grinding disc breaks during operation or the
holding fixtures on the protective guard/power tool become
damaged, the power tool must be sent to the after-sales ser-
vice immediately; see the "After-Sales Service and Applica-
tion Service" section for addresses.

Adjust the protective guard (5) such that sparking in
the direction of the operator is prevented.
Always use the protective guard for cutting (13) when
cutting bonded abrasives.
Provide sufficient dust extraction when cutting stone.
Do not operate your power tool without the side
handle (3).
Always fit the hand guard (15) when working with the
rubber sanding plate (17) or with the cup brush/disc
brush/flap disc.
Pull the plug out of the socket before carrying out any
work on the power tool.
Do not touch grinding and cutting discs until they have
cooled down. The discs can become very hot while work-
ing.
Do not press the spindle lock button while the grind-
ing spindle is moving. The power tool may become dam-
aged if you do this.
