Specifies the safety requirements for portable, hand-held internal combustion-engine driven chainsaws intended for use in arboriculture by an operator working up in trees. Guidance on the safe use of such chainsaws is given in an appendix.

This Standard specifies the safety requirements for portable, hand-held, internal combustion engine-driven chainsaws intended for use in arboriculture by a trained operator working up in trees, and with a maximum mass of 4.3 kg without guide bar and saw chain and with empty tanks. This Standard does not apply to(a) pole-mounted powered pruners; or(b) hydraulic chainsaws; or (c) electric chainsaws. NOTE: Guidance on the safe use of tree service chainsaws is given in Appendix A.
