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 is
lower for safety reasons and according to production tolerances.
B) Depends on protective guard and auxiliary handle in use
The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-specific models.
Noise/Vibration Information
Noise emission values determined according to
EN IEC 62841-2-3 .
Typically the A-weighted noise level of the power tool are:
94 dB(A); sound power level 102 dB(A). Uncertainty K =
3 dB.
Wear hearing protection!
Vibration total values a
h
(triax vector sum) and uncertainty K
determined according to EN IEC 62841-2-3 :
Surface grinding (roughing):
a
h
= 6.5 m/s

, K = 1.5 m/s

,
Disc sanding:
a
h
= 3.5 m/s

, K = 1.5 m/s

,
Cut-off grinding:
a
h
= 6.3 m/s
2
, K = 1.5 m/s

.
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 ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working 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 application tools, keeping their hands warm,
and organising workflows correctly.
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.
Soft start
GWS 750 S
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).
Speed preselection
GWS 750 S
You can preselect the required speed using the speed preselection thumbwheel (4) , even during operation. The information in
the table below describes the recommended values.
Material Application Application tool Thumbwheel position
Metal Removing paint Sanding sheet 2–3
Metal Brushing, removing rust Cup brush, abrasive disc 3
Stainless steel Grinding Grinding disc/fibre disc 4–6
Metal Rough grinding Grinding disc 6
Metal Cutting Cutting disc 6
Stone Cutting Diamond cutting disc 6
The values specified for speed levels are guide values.
u
The rated speed of the accessory must be at least
equal to the maximum speed marked on the power
tool. Accessories running faster than their rated speed
can break and fly apart.
