Grinding thin metal sheets or other materials that tend to easily vibrate 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 (3) to the off posi-
tion and then switch the power tool on again.

Starting current limitation

The electronic starting current limitation feature restricts the
power of the power tool when it is switched on and enables
operation using a 16 A fuse.

Note: If the power tool runs at full speed immediately after
being switched on, this means that the starting current limit-
ation and restarting protection mechanisms have failed. The
power tool must be sent to the after-sales service immedi-
ately; see the "After-Sales Service and Application Service"
section for addresses.

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.
