for design and construction of portable combustion-engine, hand-held chain-saws, designed
only for use by one operator and intended for forest work.
It describes methods for the elimination or reduction of hazards arising from their
use. In addition it specifies the type of information on safe working practices to
be provided by the manufacturer.
It deals with all significant hazards. It does not cover the hazard from kickback
for machines with an engine displacement over 80 cm3. The environmental aspects, except for noise, have not been considered.
Chain-saws covered by this part of ISO 11681 are designed for use by persons having read and understood the safety requirements
in the instruction handbook and using the appropriate personal protective equipment
(PPE). The chain-saws covered are designed only to be operated with the right hand
