Machinery for forestry - Portable chain-saw safety requirements and testing - Part 1: Chain-saws for forest service (ISO/FDIS 11681-1:2021)
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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 11681-1 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture
and forestry, Subcommittee SC 17, Manually portable forest machinery.This fourth edition cancels and replaces the third edition (ISO 11681-1:2011), which has been technically
revised.The main changes compared to the previous edition are as follows:
— Normative references
— Kickback (clarification of requirements)
— Throttle control (verification of requirements)
— Fuel line strength and accessibility
— Information for use - Technical data
— Instruction handbook – Safe starting procedure
ISO 11681 consists of the following parts, under the general title Machinery for forestry — Portable
chain-saw safety requirements and testing:— Part 1: Chain-saws for forest service
— Part 2: Chain-saws for tree service

Introduction
This document is a type-C standard as stated in ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events
are covered are indicated in the scope of this document.When requirements of this type-C standard are different from those which are stated in type-A or
type-B standards, the requirements of this type-C standard take precedence over the requirements of
the other standards for machines that have been designed and built according to the requirements of
this type-C standard.vi © ISO 2019 – All rights reserved

Part 1:
Chain-saws for forest service
1 Scope
This part of ISO 11681 gives safety requirements and measures for their verification for the design
and construction of portable, combustion-engine, hand-held chain-saws, intended to be used for forest
work by only one operator, by persons with the right hand on the rear handle and left hand on the front
handle having read and understood the safety requirements provided in the instruction handbook and
using the appropriate personal protective equipment (PPE). 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 part of ISO 11681 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
cm , relevant to these machines when they are used as intended and under conditions of misuse which
are reasonably foreseeable by the manufacturer.NOTE See Annex A for a list of significant hazards.
This part of ISO 11681 is applicable to chain-saws manufactured after its date of publication.

4 Safety requirements and/or protective measures
4.1 General
Machines shall comply with the safety requirements and/or protective measures of this clause. In
addition, the machine shall be designed according to the principles of ISO 12100 for relevant but not
significant hazards which are not dealt with by this part of ISO 11681.The safe operation of a chain-saw also depends on the safe environment associated with the use of
personal protective equipment (PPE), such as gloves, slip-resistant footwear, and leg, eye, foot, hearing
and head protective equipment, as well as safe working procedures (see 5.1).Except where otherwise specified in this part of ISO 11681, the safety distances specified in
ISO 13857:2008, 4.2.4.1 and 4.2.4.3, shall be met.4.2 Handles
4.2.1 Requirements
Chain-saws shall have a handle for each hand. These handles shall be designed such that
— they can be fully gripped by an operator wearing protective gloves,— they provide the necessary sureness of grip by their shaping and surface, and
— they conform to the dimensions and clearances given in ISO 7914 (see also 4.12.1). The strength of
both handles shall comply with ISO 7915.Chain-saws having a system for isolating machine vibration from the handles shall be designed so that
the operator is able to stop the engine in a controlled manner with the engine stopping device (see
4.11), even in the case of failure of the vibration isolation system.4.2.2 Verification
Dimensions shall be verified by measurement. Strength requirements shall be verified by testing in
accordance with ISO 7915. The possibility of stopping the chain-saw engine when a failure has occurred
in the vibration isolation system shall be verified by inspection of the design and by functional testing.
4.3 Hand protection4.3.1 Protection at front handle
4.3.1.1 Requirements
A hand guard shall be fitted in the vicinity of the front handle to protect the operator’s fingers and hand
from injury through contact with the saw chain.The dimensions of this front hand guard shall comply with ISO 6533. Its strength shall comply with
ISO 6534.4.3.1.2 Ver
