ISO 11681-2:1998/Amd.1:2003(E)
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.
Amendment 1 to ISO 11681-2:1998 was prepared by Technical Committee ISO/TC 23, Tractors and
machinery for agriculture and forestry, Subcommittee SC 17, Manually portable forest machinery.

 clause 3: a definition of trained operator has been added and that for chain saws for tree service has
been changed;
…”
Modify the fourth and fifth points to read
“…
 subclause 4.3: a requirement for the sideways balance, measured in accordance with a new Annex D,
has been added with a limited holding moment of 6 N⋅m;
 subclause 4.4: the non-manual chain-brake system shall meet stricter requirements than those in
ISO 13772 and the allowed kickback angle has been reduced to 25°;
…”
Delete the seventh and eleventh indents (those making reference to 4.9 and 4.10, and 4.18), and modify the
fourteenth and fifteenth indents to read
“…
 subclause 6.3: new safety warnings have been added along with a new Annex E;

Replace the first and second paragraphs of the Scope by the following.
“This part of ISO 11681 specifies safety requirements and their verification for the design and
construction of portable combustion-engine, hand-held chain-saws for tree service, designed for use by a
trained operator for pruning and dismantling standing tree crowns.
It is applicable to chain-saws having a maximum mass of the saw equal to 4,3 kg, without guide bar and
saw chain and with empty tanks.”

Pages 1 and 2, Clause 2
Add the dates as follows to the two remaining undated International Standards given in the list of normative
references:
“ISO 6531:1999, …”

Page 2, Clause 3
Replace the first paragraph by the following.
“For the purposes of this document, the definitions given in ISO 6531, with the exception of the definition
of 3.1, and the following apply.”
Replace definition 3.1 with
“ 3.1
chain-saw for tree service
specialised chain-saw of limited mass designed for use by a trained operator (see 3.2) for pruning and
dismantling standing tree crowns”
Replace 3.2, “attachment point” (defined in ISO 6531:1999), with the following term and definition.
“ 3.2
trained operator
person who has competence and knowledge in
 the use and particular hazards associated with using a chain-saw (for tree service work)

personal protective equipment (PPE)”

Page 4, 4.3
Replace the entire text of the subclause by the following.
“The chain-saw shall be balanced when fitted with the manufacturer’s recommended guide-bars. The
balance shall be tested in accordance with ISO 8334. The holding moment shall be a maximum 6 N⋅m,
when determined in accordance with Annex C.

The maximum angle of the guide-bar shall not exceed 25° above and below the horizontal plane.
Sideways balance when measured in accordance with Annex D shall be 0° ± 10°.”

Page 4, 4.4.1
Strengthen the requirements for the non-manually chain brake activation system by adding the following
limitations on the threshold values, changing the second sentence of the second paragraph to read
“The performance of the system shall be determined in accordance with ISO 13772, but with the
2 2
threshold level for activation modified to y = 1 500 m/s and x = 7
