ISO 11681-1:2004(E)
Foreword
ISO (the International Organization for Standardization) is a world-wide 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 second edition cancels and replaces the first edition (ISO 11681-1:1996), which has been technically
revised.
ISO 11681 consists of the following parts, under the general title Machinery for forestry — Portable chain-saw
safety requirements and testing:

Part 2: Tree service chain-saws

This document is a type C standard as defined in ISO 12100-2.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this document.
The provisions of this type C standard are different from those stated in type A or B standards, in that they
take precedence over the provisions of the other standards for machines that have been designed and built
according to type C standard provisions.

INTERNATIONAL STANDARD ISO 11681-1:2004(E)
Machinery for forestry — Portable chain-saw safety
requirements and testing —
Part 1:
Chain-saws for forest service
1 Scope
This part of ISO 11681 deals with the significant hazards and specifies safety requirements and their
verification for design and construction of portable combustion-engine, hand-held chain-saws, designed only
for use by one operator and intended for forest work.
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 by the manufacturer.
It deals with all significant hazards. It does not cover the hazard from kickback for machines with an engine
3
displacement over 80 cm . The environmental aspects, except for noise, have not been considered.
Chain-saws covered by this part of ISO 11681 are designed for use by persons having read and understood
the safety requirements in the instruction handbook and using the appropriate personal protective equipment
(PPE). The chain-saws covered are designed only to be operated with the right hand on the rear handle and
the left hand on the front handle.
This part of ISO 11681 is not applicable to chain-saws which are manufactured before the date of publication
of this document.

ISO 11681-1:2004(E)
5.2 Handles
5.2.1 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 when 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.
The strength of both handles shall at least comply with ISO 7915.
Chain-saws having a system for isolating the machine vibration from the handles shall be designed so that the
operator has the possibility of stopping the engine in a controlled manner with the engine stopping device (see
5.11), even in case of failure of the vibration isolation system.
5.2.2 Verification
Dimensions shall be verified by measurement. Strength requirements shall be verified by functional test in
accordance with ISO 7915. The possibility of stopping the chain-saw engine, if a failure has occurred in the
vibration isolation system, shall be verified by inspection of the design.
5.3 Hand protection
5.3.1 Protection at the front handle
5.3.1.1 Requirements
A guard shall be fitted in the vicinity of the front handle to protect the operator's fingers from injury by contact
with the saw chain.
The dimensions of this front hand-guard shall comply with ISO 6533. Its strength shall comply with ISO 6534.
5.3.1.2 Verification
Dimensions shall be verified by measurement. Strength requirements shall be verified by functional testing in
accordance with ISO 6534.
5.3.2 Protection at the rear handle
5.3.2.1 Requirements
A guard shall be provided along the length of the right side of the bottom of the rear handle to protect the
operator's hand from contact with a broken saw-chain.
This guard shall extend from the right edge of the handle for at least 30 mm at the guide bar side and at least
100 mm lengthwise (see Figure 2). This requirement may also be fulfilled by parts of the machine.
The strength of the rear hand guard shall comply with ISO 6534.
5.3.2.2 Verification
Dimensions shall be verified by measurement. Strength requirements shall be verified by functional testing in
accordance with ISO 6534.
