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 rechargeable battery (5) and protective
guard ((10), (11)) in use
C) Limited performance at temperatures < 0 °C
D) The mobile terminal devices must be compatible with
Bluetooth® Low Energy devices (version 4.2) and support the
Generic Access Profile (GAP).
E) The signal range may vary greatly depending on external condi-
tions, including the receiving device used. The Bluetooth® range
may be significantly weaker inside closed rooms and through
metallic barriers (e.g. walls, shelving units, cases, etc.).
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: 86
dB(A); sound power level 94 dB(A). Uncertainty K = 3 dB.
Wear hearing protection!

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.
Kickback control
If there is a sudden kickback in the power tool,
e.g. jamming in a separating cut, the power
supply to the motor will be interrupted elec-
tronically.
To restart the tool, set the On/Off switch (8) to the "off" po-
sition and then switch the power tool on again.
Run-out brake
The power tool is fitted with the electronic
Bosch Brake System. When it is switched off,
the abrasive tool is brought to a complete stop
within a few seconds. This means that the run-
out time is significantly shorter than for angle
grinders without a run-out brake and enables the power tool
to be set down sooner.
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-
