Part 4-8: Particular requirements for shredders/chippers

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 62841-4-8 has been prepared by IEC technical committee 116: Safety of motor-operated
electric tools. It is an International Standard.
The text of this International Standard is based on the following documents:

8.12 Replacement of the first paragraph:
Markings required by this document shall be legible and durable. Product safety labels shall be
in contrast such as colour, texture, or relief, to their background such that the information or
instructions provided by the product safety labels are clearly legible when viewed with normal
vision from a distance of (500 ± 50) mm. Product safety labels having an adhesive backing shall
be in accordance with the colour requirements of ISO 3864-2. If markings or product safety
labels are embossed, etched, stamped or moulded, contrasting colours are not required.
8.14.1 Addition:
The additional safety instructions as specified in 8.14.1.101 shall be given. These instructions
may be printed separately from the "General Machine Safety Warnings".
NOTE 101 "General Machine Safety Warnings" are referred to as "General Power Tool Safety Warnings" in
IEC 62841‑1:2014.
8.14.1.1 General power tool safety warnings
2) Electrical safety
Modification of item c):
For machines classified at least IPX4, this warning may be replaced as specified below.
c) Do not operate the power tool in rain or wet conditions. This may increase the risk of
electric shock.
NOTE 101 In accordance with IEC 62841-1:2014, 8.14.1, it is possible to replace the term "power tool" with an
appropriate term such as "machine" in the warnings above.
8.14.1.101 Safety instructions for shredders/chippers
The term "machine" may be replaced by alternate wording (e.g. "shredder", "chipper",
"shredder/chipper" or "mulcher").
Shredder/chipper safety warnings:
a) Do not use the machine in bad weather conditions, especially when there is a risk of
lightning. This decreases the risk of being struck by lightning.
b) Do not use dull or damaged shredding means. Unsharpened or damaged shredding
means may increase the risk of kickback.
c) Check the debris collector frequently for wear or deterioration. A worn or damaged
debris collector may increase the risk of personal injury.
NOTE 101 The term "collector" in item c) above can be replaced by the term "bag".
NOTE 102 The warning in item c) above is omitted for machines that are not intended to be used with a debris
collector.
d) Keep guards in place. Guards must be in working order and be properly mounted. A
guard that is loose, damaged, or is not functioning correctly may result in personal injury.
e) Keep all cooling air inlets clear of debris. Blocked air inlets and debris may result in
overheating or risk of fire.
f) Operate the machine on firm level ground. Operating the machine on firm level ground
reduces the risk of the machine falling over and reduces the risk of injury.
g) While operating the machine, always wear close fitting gloves appropriate for
protecting against mechanical risks such as puncture (e.g. thorns or splinters) and
cuts (e.g. while clearing blockages). This reduces the risk of injury to hands while feeding
long or multiple branches and during maintenance.

h) While operating the machine, always wear long trousers. Exposed skin increases the
likelihood of injury from branches and thrown objects.
i) While operating the machine, always wear non-slip and protective footwear. Do not
operate the machine when barefoot or wearing open sandals. This reduces the risk of
injury to the feet.
j) Never allow the hands, other parts of the body or clothing to enter the feed intake
opening. Putting hands, other parts of the body or clothing into the feed intake opening
increases the risk of injury.
k) When feeding material into the machine, be extremely careful that pieces of metal,
rocks, bottles, cans, cables or other foreign objects are not included. Solid objects can
be thrown from the machine and cause injury.
l) Use extra caution when feeding long branches into the intake opening. Branches can
be kicked back and cause injuries.
m) Switch off and remove plug from mains if the cord is entangled or damaged. Entangled
or damaged cords can increase the risk of electric shock.
n) Do not touch blades and other hazardous moving parts while they are still in motion.
This reduces the risk of injury from moving parts.
o) When clearing jammed material, emptying the debris collector or cleaning the
machine, make sure the power switch is off and the power cord is disconnected.
Unexpected operation of the machine may result in serious personal injury.
NOTE 103 The term "collector" in item o) above can be replaced by the term "bag".
NOTE 104 The text ", emptying the debris collector" in item o) above can be omitted for machines that are not
intended to be used with a debris collector.
p) Never leave the machine running unattended. Turn it off and do not leave the machine
until it comes to a complete stop. An unattended running machine is an uncontrolled
hazard.
