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
user must make sure, that the connection point, with the impedance 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

determined according to EN 60745-2-3:
Surface grinding (roughing):

Disc sanding:
2 2
a = 2.7 m/s , K = 1.5 m/s .

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.
Protective guard for grinding with clamping lever
Open the clamping lever (9). Place the protective guard (6)
with the coding cam (8) engaging into the coding groove on
the spindle collar until the shoulder of the protective guard is
seated against the flange of the power tool, and turn the pro-
tective guard (6) to the required position. Close the clamp-
ing lever (9).
Adjust the protective guard (6) such that sparking in
u
the direction of the operator is prevented.
The tensioning force of the clamp from the protective
guard (6) can be changed by loosening or tightening the ad-
justment screw (10). Ensure that the protective guard (6) is
fitted securely and check it regularly.
Note: The coding cams on the protective guard (6) ensure
that only a protective guard that is suitable for the power
tool can be fitted.
Protective guard for grinding with locking screw
Place the protective guard (7) on the spindle collar. Adjust
the position of the protective guard (7) to the requirements
of the operation and lock the protective guard (7) with the
locking screw (11).
Adjust the protective guard (7) such that sparking in
u
the direction of the operator is prevented.
