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.
When you take off the outer cover for maintenance purposes, store it
sufficiently away from the working area.
