17 This document modifies by common modifications FprEN 62841-4-4:2020, which consists of the text of
18 IEC 62841-4-4:2020, Ed. 1) prepared by IEC/TC 116 “Safety of motor-operated electric tools”.
19 If approved, this draft amendment will be published as EN 62841-4-4:202x/A11:202x.
20 This series is divided into four parts:
21 Part 1: General requirements which are common to most hand-held electric motor operated tools (for the
22 purpose of this document referred to simply as tools) which could come within the scope of this document;
23 Part 2, 3 or 4: Requirements for particular types of tools which either supplement or modify the requirements
24 given in Part 1 to account for the particular hazards and characteristics of these specific tools.
25 The Part 4-4 is used in conjunction with EN 62841-1:2015 + A11:2022.
26 The Part 4-4 supplements or modifies the corresponding clauses in EN 62841-1:2015 + A11:2022, so as to
27 convert it into the European Standard: Particular requirements for lawn trimmers, lawn edge trimmers, grass
28 trimmers, brush cutters and brush saws.
29 Where a particular subclause of Part 1 is not mentioned in Part 4-4, that subclause applies as far as relevant.
30 When this document states “addition”, “modification” or “replacement”, the relevant text in Part 1 is to be adapted
31 accordingly.
32 The following print types are used:
33 — requirements; in roman type
34 — test specifications: in italic type;
35 — notes: in smaller roman type.
36 The terms defined in Clause 3 are printed in bold typeface.
37 Subclauses, notes, tables and figures which are additional to those in Part 1 are numbered starting from 101.
38 Clauses, subclauses, notes, tables, figures and annexes which are additional to those in IEC 62841-4-4:2020
39 are prefixed “Z”.
40 This document follows the overall requirements of EN ISO 12100:2010.
41 This document has been prepared under a Standardization Request addressed to CENELEC by the European
42 Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
43 Member States.
44 For the relationship with EU Legislation, see informative Annex ZZ, which is an integral part of this document.
45 Compliance with the clauses of Part 1 together with Part 4-4 provides one means of conforming with the
46 essential health and safety requirements of the Directive concerned.
47 1 Modifications to Clause 8, “Marking and instructions”
48 Add the following new text:
49 “8.14 Addition:
50 For machines intended to be used by non-professional users, the wording and layout of the instruction manual
51 shall take into account the level of general education that can reasonably be expected from the users.”
52 Delete the NOTE after 8.14.2 c) 105) and replace with the following normative text:
53 “8.14.2 Za) Replacement:
54 Emissions
55 1) The noise emission, measured in accordance with I.2, as follows:
56 — A-weighted emission sound pressure level L and its uncertainty K , where L exceeds 70 dB(A).
pA pA pA
57 Where L does not exceed 70 dB(A), this fact shall be indicated;
pA
58 — for lawn trimmers and lawn edge trimmers, the A-weighted measured and guaranteed sound power
59 levels L ;
WA
60 — for grass trimmers, brush cutters and brush saws, the A-weighted sound power level L and its
WA
61 uncertainty K , where the A-weighted emission sound pressure level L exceeds 80 dB(A).
WA pA
62 2) Recommendation for the operator to wear hearing protection.
63 3) The vibration total value and its uncertainty measured in accordance with I.3.
64 When the vibration total value does not exceed 2,5 m/s , this shall be stated.
65 When the vibration total value exceeds 2,5 m/s , its value shall be given in the instructions.
66 4) The following information:
67 — that the declared vibration total value(s) and the declared noise emission value(s) have been measured
68 in accordance with a standard test method and may be used for comparing one machine with another;
69 — that the declared vibration total value(s) and the declared noise emission value(s) may also be used
70 in a preliminary assessment of exposure.
71 5) A warning:
72 — that the vibration and noise emissions during actual use of the machine can differ from the declared
73 total value depending on the ways in which the machine is used; and
74 — of the need to identify safety measures to protect the operator that are based on an estimation of
75 exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the
76 times when the machine is switched off and when it is running idle in addition to the trigger time).”
77 2 Modification to Clause 21, “Construction“
78 Replace the title of subclause 21.102 as follows:
79 “21.102 Distance from guard to power switch”
80 3 Modifications to Annex I, “Measurement of noise and vibration emissions”
81 Replace the title of Annex I with the following:
82 “Annex I
83 (normative)
85 Measurement of noise and vibration emissions”
86 and delete the NOTE.
87 Replace the existing NOTE in subclause I.2.2.1 with the following:
88 “
89 NOTE For grass trimmers with a cutting element having a kinetic energy of not more than 10 J, lawn trimmers and
90 lawn edge trimmers, the determination of the sound power level in accordance with I.2.2.4 also provides the basis for the
91 determination of the A-weighted measured and guaranteed sound power level L required by the European Directive
WA
92 2000/14/EC and its amendments.”
93 4 Modification to Annex K, “Battery tools and battery packs”
94 Replace the existing NOTE 301 in K.1 with the following normative paragraph:
95 “This annex does not apply to grass trimmers, brush cutters and brush saws equipped with integral
96 batteries.”
97 Replace item cc and NOTES 302 and 303 of K.8.14.1.102 with the following:
98 “cc) When clearing jammed material or servicing the machine, make sure the switch is off and the
99 machine is disabled. Unexpected starting of the machine while clearing jammed material or servicing may
100 result in serious personal injury.
101 NOTE 302 The above warning is omitted for machines with detachable battery packs and separable battery packs.”
102 Replace the NOTE in K.21.18 with the following normative text:
103 “K.21.18.Z101 Isolation device
104 Hand-held trimmers and walk-behind trimmers with an integral battery shall be equipped with an isolation
105 device to prevent the risk of injury from mechanical hazards during servicing or user maintenance.
106 An isolation device shall:
107 — provide disconnection of at least one pole of the battery from the serviceable region of the machine;
108 — be equipped with an unambiguous indication of the state of the disconnection device which corresponds to
109 each position of its manual control (actuator);
110 — be provided with protection against accidental reconnection.
111 NOTE 1 Examples of methods to achieve this disconnection include removable jumpers, integral batteries that can be
112 disconnected for servicing or user maintenance, or an electromechanical power switch with a direct mechanical link
113 between the actuator and the contact.
114 NOTE 2 The risk of accidental reconnection for a power switch is addressed by the requirement of 21.18.1.2. The other
115 examples in NOTE 1 achieve this by the necessary actions for reconnection.
116 Compliance is checked by inspection and by manual test.”
117 Replace the existing subclause K.21.302.1 with the following:
