This part of ISO 11681 specifies safety requirements and their verification for the design and construction of portable combustion-engine, hand-held chain-saws for tree service, having a maximum mass, without guide bar or saw chain and with tanks empty, equal to 4,3 kg, and designed for use by a trained operator for pruning and dismantling standing tree crowns. 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. This document deals with all significant hazards, hazardous situations or hazardous events relevant to these machines, as well as when they are used as intended and under condition of reasonable foreseeable misuse. NOTE See Annex C for list of significant hazards. Chain-saws covered by this part of ISO 11681 are designed to be operated with the right hand on the rear handle and the left hand on the front handle by persons having read and understood the safety requirements in the instruction handbook and using the appropriate personal protective equipment (PPE). This part of ISO 11681 is not applicable to chain-saws which are manufactured before its date of publication of this standard.
