Overview

EN IEC 62841-4-3:2021/FprA1:2025 is an amendment (A1) to the international safety standard for electric motor‑operated pedestrian controlled walk‑behind lawnmowers. Developed by IEC TC 116 and adopted regionally (CLC/EN), this document updates particular safety requirements for walk‑behind mowers used in lawn and garden machinery. It clarifies definitions, expands marking and instruction requirements, and adds normative references for insulation, switches and acoustics. The amendment excludes machines with a swing‑over handle and targets manufacturers, test labs and conformity assessors.

Key Topics and Requirements

• Scope and exclusions: Applies to pedestrian controlled walk‑behind lawnmowers; explicitly excludes lawnmowers with a swing‑over handle in the EN implementation.
• Definitions: Revised definitions such as maximum speed (steady‑state cutting means speed) and a new term traction drive (system transmitting power from motor to ground drive means).
• Marking and instructions:
  • Updated mandatory safety warnings (e.g., “WARNING – Beware of thrown objects – keep bystanders away”) and minimum bystander distance marking.
  • Requirement to mark ear protection unless measured A‑weighted sound pressure at the operator’s ear (per Annex I) ≤ 85 dB(A).
  • North American specific labeling guidance: conformity options with ANSI B71.1:2017 and 16 CFR 1205 labeling dimensions and placement for cylinder and rotary mowers.
  • Requirements for machine mass marking and additional European marking for replaceable cutting‑means part identification.
• Safety instructions and user warnings: Harmonized text requirements (e.g., mandatory wording, French equivalents for Canada) and formatting (signal word sizes).
• Technical references: Adds or updates normative references on insulation coordination, switch requirements, acoustics and safety distances.

Applications and Users

• Manufacturers and designers of walk‑behind lawnmowers use this standard to design safer products and prepare compliant user manuals and labels.
• Test laboratories and certification bodies apply the standard for conformity assessment, marking inspection and acoustic testing.
• Safety engineers, product compliance teams and regulators reference it when assessing machine hazards, user warnings and labeling requirements across EU and North American markets.

Related Standards

Key normative references added or cited include:

• IEC 60664‑3, IEC 60664‑4 (insulation coordination)
• IEC 61058‑1 / IEC 61058‑2‑6 (switches)
• IEC 61672‑1; ISO 354; ISO 11201; ISO 3744 (acoustics and sound measurement)
• ISO 13857 (safety distances); ISO 11684 (safety labels)
• ANSI B71.1:2017 and 16 CFR 1205 (North American labeling)

This amendment is essential for ensuring regulatory compliance and practical safety controls in the design, labeling and testing of pedestrian controlled walk‑behind lawnmowers.

11 AMENDMENT 1
13 FOREWORD
14 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
15 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
16 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
17 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
18 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
19 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
20 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
21 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
22 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
23 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
24 consensus of opinion on the relevant subjects since each technical committee has representation from all
25 interested IEC National Committees.
26 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
27 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
28 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
29 misinterpretation by any end user.
30 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
31 transparently to the maximum extent possible in their national and regional publications. Any divergence between
32 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
33 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
34 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
35 services carried out by independent certification bodies.
36 6) All users should ensure that they have the latest edition of this publication.
37 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
38 members of its technical committees and IEC National Committees for any personal injury, property damage or
39 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
40 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
41 Publications.
42 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
43 indispensable for the correct application of this publication.
44 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
45 rights. IEC shall not be held responsible for identifying any or all such patent rights.
46 Amendment 1 to IEC 62841-4-3:2020 has been prepared by IEC technical committee 116:
47 Safety of motor-operated electric tools.
48 The text of this Amendment is based on the following documents:

246 contact hidden wiring or its own cord. Blade(s) contacting a "live" wire may make
247 exposed metal parts of the machine "live" and could give the operator an electric shock.
248 Add the following new NOTE 103 to 8.14.1.101:
249 NOTE 103 In Canada and the United States of America, the following requirements apply:
250 8.14.1.101 Replacement:
251 Lawnmower safety warnings
252 WARNING Read all safety warnings, instructions, illustrations and specifications provided with this
253 lawnmower. Failure to follow all instructions listed below may result in electric shock, fire and/or serious
254 injury.
255 Save all warnings and instructions for future reference.
256 1) Work area safety
257 a) To avoid bystander contact with the moving blade or a thrown object injury, keep the area of operation
258 clear of all bystanders, particularly small children. Stop the lawnmower and any attachment(s) if anyone
259 enters the area. Contact with the moving blade or thrown objects may result in serious personal injury or death.
260 b) Only operate the lawnmower in daylight or good artificial light. Dark areas invite accidents.
261 c) Do not operate lawnmowers in explosive atmospheres, such as in the presence of flammable liquids, gases
262 or dust. Lawnmowers create sparks which may ignite the dust or fumes.
263 d) Do not use the lawnmower in bad weather conditions, especially when there is a risk of lightning. This
264 decreases the risk of being struck by lightning.
265 e) Thoroughly inspect the area where the lawnmower is to be used and remove all stones, sticks, wires,
266 bones, and other foreign objects. Thrown objects can cause personal injury.

IEC CDV 62841-4-3/AMD1 © IEC 2024 – 8 – 116/736/CDV

267 2) Electrical safety
268 a) Lawnmower electrical plugs must match the outlet. Never modify the plug in any way. Do not use any
269 adapter plugs with earthed (grounded) lawnmowers. Unmodified plugs and matching outlets will reduce risk of
270 electric shock.
271 b) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the lawnmower. Keep the
272 cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric
273 shock.
274 c) Keep the supply cord away from the cutting blades. A damaged supply cord may result in electric shock, fire
275 and/or serious injury.
276 d) Switch off and remove plug from mains if the cord is entangled or damaged. Entangled or damaged cords
277 can increase the risk of electric shock.
278 e) When operating a lawnmower outdoors, use an extension cord suitable for outdoor use. Use of a cord
279 suitable for outdoor use reduces the risk of electric shock.
280 f) Avoid body contact with earthed or grounded surfaces, such as metal fences or signs. There is an increased
281 risk of electric shock if your body is earthed or grounded.
282 g) Do not expose the lawnmower to rain or wet conditions. Water entering a lawnmower may increase the risk of
283 electric shock.
284 NOTE 101 For machines classified at least IPX4, the words “expose the lawnmower to” in Item g) above can be
285 replaced by the words “operate the lawnmower in”.
286 h) If operating a lawnmower in a damp location is unavoidable, use a residual current device (RCD) protected
287 supply. Use of an RCD reduces the risk of electric shock.
288 NOTE 102 The term “residual current device (RCD)” in Item h) above can be replaced by the term “ground fault
289 circuit interrupter (GFCI)” or “earth leakage circuit breaker (ELCB)”.
290 3) Personal safety
291 a) Use personal protective equipment. Always wear eye protection. Protective equipment will reduce personal
292 injuries.
293 b) Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving
294 parts. Loose clothes, jewellery or long hair can be caught in moving parts.
295 c) While operating the lawnmower, always wear long trousers. Exposed skin increases the likelihood of injury
296 from thrown objects.
297 d) While operating the lawnmower, always wear non-slip and protective footwear. Do not operate the
298 lawnmower when barefoot or wearing open sandals. This reduces the chance of injury to the feet from contact
299 with the moving blade.
300 e) Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source
301 and/or batteries, picking up or carrying the lawnmower. Carrying a lawnmower with your finger on the switch or
302 energising a lawnmower that has the switch on invites accidents.
303 f) Remove any adjusting key or wrench before turning the lawnmower on. A wrench or a key left attached to a
304 rotating part of the lawnmower may result in personal injury.
305 g) Keep proper footing and balance at all times. This enables better control of the lawnmower in unexpected
306 situations.
307 h) Stay alert, watch what you are doing and use common sense when operating a lawnmower. Do not use a
308 lawnmower while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention
309 while operating a lawnmower may result in serious personal injury.
310 i) Do not let familiarity gained from frequent use of the lawnmower allow you to become complacent and
311 ignore lawnmower safety principles. A careless action can cause severe injury within a fraction of a second.
312 j) To avoid operator blade contact or a thrown object injury, stay in the operator zone behind the lawnmower
313 handles. Blade contact or thrown objects may result in serious personal injury.
314 k) Do not touch blades and other hazardous moving parts while they are still in motion. This reduces the risk
315 of injury from moving parts.
316 4) Lawnmower use and care
317 a) Use the lawnmower and accessories in accordance with these instructions, taking into account the working
318 conditions and the work to be performed. Use of the lawnmower for operations different from those intended may
319 result in a hazardous situation.

IEC CDV 62841-4-3/AMD1 © IEC 2024 – 9 – 116/736/CDV

320 b) Before using the lawnmower, always visually inspect to see that the blade and the blade assembly are
321 properly secured and not worn or damaged. Loose, worn, or damaged parts may increase the risk of injury.
322 c) Before use, check the supply cord and any extension cord for signs of damage or aging. Do not use the
323 lawnmower if the cord is damaged or worn. If the cord is damaged or worn during use, switch off the
324 lawnmower and do not touch the cord before disconnecting it from the supply. A damaged supply cord or
325 extension cord may result in electric shock, fire and/or serious injury.
326 d) Keep guards and other safety devices in place, properly mounted, and in working order. A guard or other
327 safety device that is loose, damaged, or is not functioning correctly may result in personal injury.
328 e) Keep all cooling air inlets clear of debris. Blocked air inlets and debris may result in overheating or risk of fire.
329 f) Do not use the lawnmower if the switch does not turn it on and off. Any lawnmower that cannot be controlled
330 with the switch is dangerous and must be repaired.
331 g) Do not operate the lawnmower in wet grass. Walk, never run. This reduces the risk of slipping and falling which
332 may result in personal injury.
333 h) Do not operate the lawnmower on excessively steep slopes. This reduces the risk of loss of control, slipping
334 and falling which may result in personal injury.
335 i) Do not force the lawnmower. Use the correct lawnmower for your application. The correct lawnmower will do
336 the job better and safer at the rate for which it was designed.
337 j) Be aware of the lawnmower and attachment discharge direction and do not point the lawnmower discharge
338 at anyone. Thrown objects can cause personal injury.
339 k) Use extreme caution when reversing or pulling the lawnmower towards you. Always be aware of your
340 surroundings. This reduces the risk of tripping during operation.
341 l) When working on slopes, always be sure of your footing, always work across the face of slopes, never up
342 or down, and exercise extreme caution when changing direction. This reduces the risk of loss of control, slipping
343 and falling which may result in personal injury.
344 m) Disconnect the plug from the power source before making any adjustments, changing accessories, or
345 storing the lawnmower. Such preventive safety measures reduce the risk of starting the lawnmower accidentally.
346 n) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping
347 surfaces do not allow for safe handling and control of the lawnmower in unexpected situations.
348 o) Check the grass catcher frequently for wear or deterioration. A worn or damaged grass catcher may increase
349 the risk of personal injury.
350 p) Before removing the grass catcher, turn off the motor and wait until the blade(s) comes to a complete stop.
351 The cutting blade(s) continues to rotate after the blade control is released. Never place any part of the body
352 in the blade(s) area until you are certain the motor is off and the blade(s) has stopped rotating. Contact with
353 the moving cutting blade(s) may result in serious personal injury.
354 NOTE 103 It is possible to replace the term “catcher” in Items o) and p) above by an alternative term such as
355 “collector” or “bag”.
356 NOTE 104 The warnings in Items o) and p) above are omitted for lawnmowers that can only be operated as a
357 mulching lawnmower.
358 q) Before unclogging the chute, turn off the motor, wait until the blade(s) comes to a complete stop and
359 disconnect the power cord. The cutting blade(s) continues to rotate after the blade control is released. Never
360 place any part of the body in the blade(s) area until you are certain the motor is off and the blade(s) has
361 stopped rotating. Contact with the moving cutting blade(s) may result in serious personal injury.
362 r) Before cleaning or inspecting the lawnmower, disconnect the power cord, turn off the power switch and
363 ensure the blade(s) and all moving parts have stopped. Accidental contact with the moving blade(s) and moving
364 parts may result in personal injury.
365 s) Maintain the lawnmower and accessories. Check for misalignment or binding of moving parts, breakage of
366 parts and any other condition that may affect the lawnmower’s operation. If damaged, have the lawnmower
367 repaired before use. Many accidents are caused by poorly maintained lawnmowers.
368 t) Store idle lawnmowers out of the reach of children and do not allow persons unfamiliar with the lawnmower
369 or these instructions to operate the lawnmower. Lawnmowers are dangerous in the hands of untrained users.
370 5) Service
371 a) Have your lawnmower serviced by a qualified repair person using only identical replacement parts. This
372 will ensure that the safety of the lawnmower is maintained. Use of parts which do not meet the original equipment
373 specifications may lead to improper performance and compromise safety.
