Preparation for replacing the vacuum pump
1) Check to see if the vacuum pump does not operate. (After the pump operates, the inside of the
pump gets hot. Therefore, leave the pump for approximately 30 minutes after it stops, and then
start replacing it only after making sure that it is cooled down.)
2) Remove the front lower right cover of the machine main unit.
