Procedures for cleaning the vacuum ejector
WARNING
When you perform the procedure set forth in this section, you have to
place your hands in a drive section. If you perform maintenance with
the power ON, your fingers or hands may be caught or cut off.
Turn OFF the machine and shut off the facility power supply before
starting this procedure.
Also, ensure that no other person touches the machine during
cleaning.
CAUTION
When you perform maintenance with the outer cover removed,
observe the following precaution. If you stand the removed outer
cover against the machine, you may receive injury by the cover if it is
toppled by the earthquake or like that.
After taking off the outer cover for maintenance purposes, store it
sufficiently away from the working area.
