Scope

This document specifies safety requirements and measures for verification for the design, construction, transporting and commissioning of portable, combustion-engine, hand-held chain-saws. The chain- saws are intended to be used for forest work by only one operator, with the right hand on the rear handle and left hand on the front handle. Dismantling and scrapping of the product is not covered by this document. Methods for the elimination or reduction of hazards arising from the use of these machines and the type of information on safe working practices to be provided by the manufacturer are specified. This document deals with all significant hazards, hazardous situations and hazardous events, with the exception of kickback and balance for machines with an engine displacement of more than 80 cm3, relevant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A). This document is applicable to chain-saws manufactured after its date of publication. NOTE Figure 1 shows an example of a chain-saw within the scope of this document.
