1--What sort of problems do you have with these machines?

2--They're quite complex machines and they have a lot of different components. We need to check the metal casing regularly for any signs of corrosion. We also check the brushes once a fortnight to make sure they aren't worn down. It's important to make sure everything is properly aligned and we adjust it if necessary. There is a canvas belt at the end of the assembly line. If it gets wet, it might rot so we check that regularly too.

1--這些機器有什么問題？

2--這些機器相當復雜，它們有很多不同的配件。我們需要檢查一下金屬外殼看看有沒有腐蝕的痕跡。我們也要兩星期一次對刷子進行檢查，確定沒有磨損。確保每個件進行合適的校正是非常重要的，如果有必要我們要對其調整。在裝配線的尾部有個帆布帶。如果帆布袋濕了，它會腐爛，因此我們對它也要進行定期檢查。
