– a cable-retaining device to keep the cable out of the vicinity of the tines, to which the cable may be
adequately fastened, or
– the supply cable entry or attachment being at least 0,6 m from the nearest point of the tines.
Compliance is checked by inspection and by the following test procedure, except for automatic cord
reel-in devices.
The supply cable as delivered with the machine is attached to the device in accordance with the
instruction manual. The supply cord is then subjected 10 times to a pull of 100 N, the pull being applied in
the most unfavourable direction, without jerks, for 1 s.
After the test the power supply cord shall show no damage within the meaning of this standard and it shall
not have been displaced longitudinally, in the device, by more than 2 mm.
22.102 Air filters which can be removed for cleaning purposes shall be so designed that they are
unlikely to come off during use.
This requirement is met if, for example, the air filter
– can only be removed with the aid of a tool, or
– is provided with a spring that prevents it from falling away, during use, due to vibration, or
– needs a deliberate action of the user for its removal.
