The rated speed of the diamond wheel does not exceed a peripheral speed of 100 m/s at rated capacity.

This document does not apply to transportable wall saws with a design that allows an automatic change of the cutting direction without user intervention before any change of the cutting direction.

This document does not apply to transportable wall saws that employ hydraulic systems.

This document does not apply to hand-held cut-off machines.

NOTE 101 Hand-held cut-off machines will be covered by a future part of IEC 62841-2.

This document covers all significant hazards, hazardous situations or hazardous events relevant for tools covered by this standard.
