IEC CDV 62841-4-2/AMD1 ED1 © IEC: 2021 – 4 – 116/499/CDV

78 The DANGER marking or symbol shall be readily visible to the user and shall not be located

79 on the underside of the machine.
80 For all hedge trimmers with a degree of protection of less than IPX4:

81 – “ WARNING – Do not expose to rain” or the safety sign specified in Figure AA.3.

82 For mains supplied machines:

83 – “ WARNING – Remove plug from the mains immediately if the cable is damaged or cut”;

84 or the safety sign specified in Figure AA.4.
85 For all hedge trimmers except for Category 1 in Table 101:

86 – “Wear eye protection” or a relevant safety sign of ISO 7010 or one of the safety signs

87 specified in Figure AA.5.
88 Additionally, for extended-reach hedge trimmers:

89 – “ DANGER – Keep sufficient distance away from electrical power lines” or symbol

90 C.2.30 of ISO 11684.
91 – “Wear head protection” or a relevant safety sign of ISO 7010.

92 A combination of ISO safety signs, such as eye and head protection, is allowed. In addition, a

93 combination of safety signs as specified in Figure AA.6 is allowed.
94 Add the following new subclause:
95 8.14.1.1 Addition for item 2) c):

96 For machines classified at least IPX4, the warning may be replaced as specified below.

97 c) Do not operate the machine in rain or wet conditions. Water entering the machine may

98 increase the risk of electric shock or malfunction that could result in personal injury.

99 Replace the existing text of 8.14.1.101 with the following new text:
100 8.14.1.101 Safety instructions for hedge trimmers

101 For Category 1 hedge trimmers that can be converted to a grass shear, the term “hedge

102 trimmer” may be replaced by alternate wording (e.g. “grass shear/hedge trimmer” or “grass

103 shear/shrub shear”). For this case, the verbatim warnings below need not be repeated for the

104 two configurations.
105 Hedge trimmer safety warnings:

106 a) Do not use the hedge trimmer in bad weather conditions, especially when there is a

107 risk of lightning. This decreases the risk of being struck by lightning.

108 b) Keep all power cords and cables away from cutting area. Power cords or cables may

109 be hidden in hedges or bushes and can be accidentally cut by the blade.

110 c) Wear ear protection. Adequate protective equipment will reduce the risk of hearing loss.

111 NOTE 101 This warning can be omitted if the measured emission sound pressure level at the operator’s ear

112 in accordance with Annex I does not exceed 85 dB(A).

113 d) Hold the hedge trimmer by insulated gripping surfaces only, because the blade may

114 contact hidden wiring or its own cord. Blades contacting a "live" wire may make

115 exposed metal parts of the hedge trimmer "live" and could give the operator an electric

116 shock.

117 e) Keep all parts of the body away from the blade. Do not remove cut material or hold

118 material to be cut when blades are moving. Blades continue to move after the switch is

119 turned off. A moment of inattention while operating the hedge trimmer may result in

120 serious personal injury.

121 f) When clearing jammed material or servicing the hedge trimmer, make sure all power

122 switches are off and the power cord is disconnected. Unexpected actuation of the

123 hedge trimmer while clearing jammed material or servicing may result in serious personal

124 injury.

125 g) Carry the hedge trimmer by the handle with the blade stopped and taking care not to

126 operate any power switch. Proper carrying of the hedge trimmer will decrease the risk of

127 inadvertent starting and resultant personal injury from the blades.

128 h) When transporting or storing the hedge trimmer, always use the blade cover. Proper

129 handling of the hedge trimmer will decrease the risk of personal injury from the blades.

130 Replace the existing text of 8.14.1.102 with the following new text:
131 8.14.1.102 Additional safety instructions for extended-reach hedge trimmers
132 Extended-reach hedge trimmer safety warnings:

133 a) Always use head protection when operating the extended-reach hedge trimmer

134 overhead. Falling debris can result in serious personal injury.

135 NOTE 101 Alternate wording for "extended-reach" is possible, e.g. “pole” or “long reach”.

136 b) Always use two hands when operating the extended-reach hedge trimmer. Hold the

137 extended-reach hedge trimmer with both hands to avoid loss of control.

138 c) To reduce the risk of electrocution, never use the extended-reach hedge trimmer

139 near any electrical power lines. Contact with or use near power lines may cause serious

140 injury or electric shock resulting in death.
141 14 Moisture resistance
142 Replace the existing text of 14.2.1 with the following new text:
143 14.2.1 Replacement:
144 The machine is not connected to the supply.

145 The machine is placed in its normal rest position on a perforated turntable. The turntable is

146 then turned continuously at (1 ± 0,1) /min during the test.
147

148 Detachable parts are removed and subjected, if necessary, to the relevant treatment with the

149 main part. Movable covers that are non-detachable parts and are not self-restoring are

150 placed in the most unfavourable position.

151 NOTE Examples of self-restoring covers include those that are spring loaded or close by gravity.

152 Replace the existing text of 14.2.2 with the following new text:
153 14.2.2 Addition:

154 Alternatively, extended-reach hedge trimmers may be subjected to the test described in

155 14.2.3 b) or 14.2.4 b) of IEC 60529:2013, as applicable.
156 Replacement of the last paragraph:

157 Immediately after the appropriate treatment, the machine shall withstand the electric strength

158 test of Annex D between live parts and accessible parts, the test voltage being 2 500 V.

159 Then the machine is connected to the supply. It shall not start with the power switch in the

160 “off” position.

161 Afterwards, inspection shall show that there is no trace of water on insulation which could result

162 in a reduction of creepage distances between bare conductors of different potential below the

163 values specified in 28.1. For all instances where creepage distances could be reduced below

164 the values specified in 28.1, a short circuit is introduced between adjacent conductors

165 simultaneously. The machine is then evaluated for
166 – the risk of fire in accordance with item a) of 18.6.1; and
167 – the loss of any SCF, unless the machine is rendered into a safe state.
168 17 Endurance

286 to multiple drops without failure. If a sample has been subjected to multiple drops and fails,

287 then the drop in the orientation that resulted in the failure is repeated using a new sample. If

288 the new sample passes the test for the drop in that orientation, then the requirements for the

289 drop in that orientation are considered to be fulfilled. The test is continued in this manner until

290 all drops in each of the four orientations are completed.

301 Replace the existing text of 21.18.102.3 with the following new text:

302 21.18.102.3 The hedge trimmer shall be provided with a blade control having a lock-off

303 device such that at least two separate and dissimilar actions are required before drive to the

304 cutting device is possible. It shall not be possible to achieve these actions with a single

305 grasping motion or a straight line motion within any grasping surface identified in accordance

306 with 8.14.2 b) 6).

307 Drive to the cutting device shall only be enabled when the lock-off device is operated prior to

308 the power switch.

309 It shall not be necessary to sustain the actuation of the lock-off device until the blade control

310 is activated, provided

311 – the blade control or an operator presence sensor (if any) is activated within 5 s of the

312 release of the lock-off device; and

313 – there is a visual or audible indication as soon as the lock-off actuator is released and

314 continues at least until the blade control or an operator presence sensor (if any) is

315 activated;
316 or

317 – an operator presence sensor (if any) is activated prior to the release of the actuator of

318 the lock-off device.

319 NOTE The visual or audible indication is intended to only indicate the state of the hedge trimmer.

320 The hedge trimmer shall return to the original locked state within 5 s when the blade control

321 is released (i.e. at least two separate and dissimilar actions are required before drive to the

322 cutting device is possible), unless
323 – an operator presence sensor is provided; and
324 – the hand is not released from the operator presence sensor.

325 The operator presence sensing function may be achieved by any combination of mechanical,

326 electrical or electronic means.
327 Compliance is checked by inspection, by measurement and by manual test.

328 Additionally, for lock-off devices that are actuated in a direction generally perpendicular to the

329 longitudinal vertical plane of the machine, (see Figure 124), and that are located within any

330 grasping surface of handle(s) or grasping surface(s) identified in accordance with

331 8.14.2 b) 103), in order to determine if it is possible to actuate the blade control and the lock-

332 off device with a single grasping motion or a straight line motion, compliance is checked by

333 the following test:

334 With the blade control in the "off" position, a 25 mm diameter x 75 mm long steel rod with a

335 force not exceeding 20 N is applied to the lock-off device in any direction. The steel rod shall

336 be applied such that its cylindrical surface bridges the surface of the lock-off device and any

337 surface adjacent to the lock-off device. During the test, it shall not be possible to actuate the

338 blade control with a force not exceeding 20 N.
339 Replace the existing text 21.30.101 with the following new text:

340 21.30.101 Extended-reach hedge trimmers are considered to be machines likely to cut into

341 concealed wiring or their own cord and shall meet the following requirements:

342 Handles and grasping surfaces of extended-reach hedge trimmers, as specified in 8.14.2 b)

343 6), shall be formed of insulating material or, when of metal, shall be either adequately covered

344 by insulating material having a thickness of at least 1 mm or their accessible parts shall be

345 isolated by insulating barrier(s) from accessible metal parts that may become live by the

346 cutting device. These insulating barriers are not to be regarded as basic insulation,

347 supplementary insulation or reinforced insulation.

348 An insulated, stick type, auxiliary handle shall be provided with a flange having a height not

349 less than 12 mm above the handle and covering at least 2/3 of the periphery to provide a

350 barrier to minimize the likelihood of the hand from slipping onto surfaces that are not suitably

351 insulated or isolated.
