Classification according to ISO 7176-28:2012
Type C (table 1 of annex A)
1) The climbing speed as well as the range with one charge of the batteries is reduced if the ComfortStep is activated.
2) Never use the stair climber to climb stairs with too little depth because it is no longer possible for the main wheels to touch the steps safely.
3) Temperatures below 0°C will reduce the performance of the battery pack, therefore we recommend a storage temperature of at least 0°C.
