1-- Why have you stopped production?
 
2-- We've had a few problems. One of the bolts has worked loose and a blade has snapped off.
 
1--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?
 
2--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.
 
1-- Clean up the mess first, then fit a new seal and check the valve.

譯文：
 
1--你為什么停產？
2--有點問題。有個螺栓松了，一個刀片折斷了。
1--哦。一定要關掉電源后旋緊所有的螺栓并更換刀片。為什么地上到處都是油？
2--我想是閥門的故障吧。我沒法調節(jié)壓力，墊圈破了，我試著打開應急閥，但是堵了。
1--首先清除臟物，然后換一個新的墊圈并檢查一下閥門。
