4.4 Noise information in accordance with EN 15027
The sound pressure and vibration values given in these instructions have been measured
in accordance with a standardized test and may be used to compare one power tool with
another.
Sound emissions in operation can vary up to 10 dB(A) from the stated measured values,
depending on the type of diamond saw blade used and the operating conditions. Adapt
ear protection and other noise-control measures to the specific operating conditions.
The noise pressure level can be reduced by approx. 10 dB(A) when noise-reducing
(silent) saw blades are used.

5 Planning
5.1 Cutting sequence
▶
Make dividing cuts to adjust the maximum size and weight of the concrete blocks
to the prevailing conditions (i.e. the lifting capacity of the crane or the maximum
permissible floor loading capacity and size of doors).
A rational cutting sequence can be achieved by appropriate spacing of the track
supports.
The illustration shows an example of the cutting sequence for a door opening with a
dividing cut
▶
Secure the parts to be cut away so that they cannot move. Movement of the parts
being cut can cause the saw blade to jam, presenting a risk of injury!
