A) Rated no-load speed for the selection of appropriate application tools in accordance with EN IEC 62841-2-3. The actual no-load speed
must not exceed the rated no-load speed and is therefore lower.
B) Depends on protective guard ((13), (5), (24)) and auxiliary handle ((3), (28)) in use
C) Weight without mains connection cable and without mains plug
The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-specific models.
Values can vary depending on the product, scope of application and environmental conditions. To find out more, visit

Noise/Vibration Information
Noise emission values determined according
to EN IEC 62841-2-3.
Typically, the A-weighted noise level of the power tool is:
Sound pressure level 96 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
h
determined according to EN IEC 62841-2-3:
Surface grinding (roughing):
2 2
a = 8.7 m/s , K = 1.5 m/s ,
h
Disc sanding:
2 2
a = 6.5 m/s , K = 1.5 m/s ,
h
Cut-off grinding:
2 2
a = 6.5 m/s , K = 1.5 m/s .
h
Grinding thin metal sheets or other materials that tend to easily vi-
brate with a large surface area can cause the noise emission value to
increase by up to 15 dB. Suitable, heavy damping mats can reduce
the increased noise emissions. Increased noise emissions must be
taken into consideration, both for the risk assessment of the noise
output and for selecting suitable hearing protection.
The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ac-
cessories or is poorly maintained, the vibration level and
noise emission value may differ. This may significantly in-
crease the vibration and noise emissions over the total work-
ing period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
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 accessories, keeping their hands warm, and
organising workflows correctly.

kg 5.8–6.9
Soft start
The electronic soft start limits the torque when the power
tool is switched on and enables a smooth start-up.
Note: If the power tool runs at full speed immediately after
being switched on, this means that the soft start and restart
protection mechanisms have failed. The power tool must be
sent to the after-sales service immediately; see the "After-
Sales Service and Application Service" section for ad-
dresses.
Restart protection
The restart protection feature prevents the power tool from
uncontrolled starting after the power supply to it has been
interrupted.
To restart the tool, set the on/off switch (2) to the "off" posi-
tion and then switch the power tool on again.
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
Place the protective guard (5) on the spindle collar. Adjust
the position of the protective guard (5) to the requirements
of the operation and lock the protective guard (5) with the
locking screw (6).
Adjust the protective guard (5) such that sparking in
u
the direction of the operator is prevented.
Protective guard for cutting
For cutting, always use the protective guard for
u
cutting (13) or the protective guard for grinding (5)
together with the cover for cutting (24).
Provide sufficient dust extraction when cutting stone.
u
The protective guard for cutting (13) is fitted in the same
way as the protective guard for grinding (5).
