Mechanical problem 2
机械故障2
A: Why have you stopped production?
A:你为什么停产？
B: We've had a few problems. One of the bolts has worked loose and a blade has snapped off.
B:有点问题。有个螺栓松了，一个刀片折断了。
A:OK. Make sure the power is switched off then tighten up all the bolts on the unit and replace the broken blade. Why is there oil all over the floor?
A:哦。一定要关掉电源后旋紧所有的螺栓并更换刀片。为什么地上到处都是油？
B:I think the valve is faulty. J^couldn't regulate the pressure and the seal burst.I tried opening the emergency valve but it was jammed.
B:我想是阀门的故障吧。我没法调节压力，垫圈破了，我试着打开应急阀，但是堵了。
A: Clean up the mess first, then fit a new seal and check the valve.
A:首先清除脏物，然后换一个新的垫圈并检查一下阀门。
