求翻译：开刃时打开水箱出水阀门,用锯片切割强研磨性的材料(如耐火砖,废旧砂轮等),使锯片表层金刚石露出后,方可进行正常使用是什么意思？

Blade when the water tank valve open, with a strong abrasive cutting blade materials (such as bricks, scrap wheel, etc.), so that the diamond saw blade surface exposed only after normal use

When you try to open the blade out of the water valves, water tanks with a blade cutting the abrasive material (such as fire brick, etc. ) so that waste and old grinding wheel surface diamond blade, which may be looked after normal use

Operates when the edge turns on the water tank water leakage valve, cuts the strong abrasiveness with the saw blade material (for example refractory brick, worn out grinding wheel and so on), after causes the saw blade surface layer diamond to reveal, only then carries on the normal use

When opening the blade open water tank outlet valves, saw blade cutting strength of abrasive material (such as fire-resistant brick, waste grinding wheels, and so on), the surface layer of diamond saw blade after the show, before the normal use
