They may be equipped with a traction drive system. The following power systems are covered:
– Internal combustion engines
– Mains powered motors up to a rated voltage of 250 V for single-phase appliances and 480 V for
other appliances
– Battery powered motors.
Battery powered machines may be equipped with a built-in battery charger.
This standard does not apply to
– Machines designed to be part of a production process
– Machines designed for use in corrosive or explosive environments (dust, vapour or gas)
– Machines designed for use on slopes with a gradient exceeding 20 %
– Machines equipped with a power take-off (PTO)
– Machines designed for picking up hazardous dusts as defined in EN 60335-2-69, inflammable
