IEC 62841-4-3:2020 pdf download – Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery – Safety – Part 4-3: Particular requirements for pedestrian controlled walk-behind lawnmowers.
8.1 4.2 b) Addition: 1 01 ) Hazards which may be encountered while using the lawnmower, such as blockage of the cutting means, and how to avoid them while performing typical tasks; 1 02) Instructions to stop the cutting means if the machine has to be tilted for transportation when crossing surfaces other than grass and when transporting the machine to and from the area to be used; 1 03) Instructions not to tilt the machine when switching on the motor, except if the machine has to be tilted for starting. In this case, instruction not to tilt it more than absolutely necessary and to lift only the part which is away from the operator; 1 04) Instructions to stop the machine, and remove plug from the socket, and to make sure that all moving parts have come to a complete stop – after striking a foreign object, and to inspect the machine for damage and make repairs before restarting and operating the machine; – if the machine starts to vibrate abnormally, and then to immediately inspect for damage, replace or repair any damaged parts and to check for and tighten any loose parts; 1 05) Recommendation for the use of a residual current device with a tripping current of 30 mA or less; 1 06) Instructions to empty the grass catcher before storage. 8.1 4.2 c) Addition: 1 01 ) Information regarding regular maintenance routines; 1 02) Recommendations for cleaning and maintenance before storage; 1 03) Information explaining the consequences of improper maintenance, the use of non- conforming replacement components, or the removal or modification of safety components; 1 04) Instruction to replace worn or damaged components in sets to preserve balance, as applicable; 1 05) Instructions for machines with multiple cutting means, to take care as rotating one cutting means can cause other cutting means to rotate; 1 06) Instructions to be careful during adjustment of the machine to prevent entrapment of the fingers between moving cutting means and fixed parts of the machine;
8.1 4.3 Replacement: If information about the mass or weight of the machine is provided, it shall be the mass specified in 5.1 7 together with the mass of a supply cord with a length not less than 1 0 m, if any. Compliance is checked by inspection. 9 Protection against access to live parts This clause of Part 1 is applicable, except as follows: 9.2 Addition: For machines that are class II tools, access to the surface of basic insulation or metal parts separated from live parts by basic insulation is permitted when the cutting means is removed, if the use of a tool is required for its removal. 10 Starting This clause of Part 1 is applicable. 11 Input and current This clause of Part 1 is applicable. 12 Heating This clause of Part 1 is applicable, except as follows: 12.2.1 Replacement: The load conditions for the heating test of 12.2 are as follows. The test is conducted with the machine mounted on an unperforated flat horizontal surface with the cutting means attached, and with the minimum size of openings for connection to the torque load. The traction drive wheels, if any, are lifted the minimum amount required to avoid contact with the unperforated flat horizontal surface. The lawnmower is operated with a torque load applied such that rated input or rated current is drawn until thermal equilibrium is reached under the most unfavourable conditions. For machines with more than one motor (i.e. separate motors for the cutting means and traction drive), the lawnmower is operated with torque loads such that rated input or rated current of each motor in accordance with 8.1.101 is drawn until thermal equilibrium is reached under the most unfavourable conditions.
