This document specifies safety requirements and measures for verification for the design, construction, transporting and commissioning for tree service of portable, combustion-engine, hand-held chain-saws having a maximum mass of 4,3 kg (without the guide bar and saw-chain and with tanks empty). The chain-saws are intended to be used, with the right hand on the rear handle and left hand on the front handle, by a trained operator. 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 relevant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex B). 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.
