For any machine breakdown under normal use conditions within warranty period, we will be responsible for free maintenance; if the machine breakdown is due to improper human operation and there is a need to replace certain components, then certain fee shall be charged.
    2. We will still be responsible for maintenance beyond warranty period, but associated fee will be charged. If any component placement occurred, there would be one-year warranty for that component, too.
