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

operation.

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.

- The roll cover memories its winding shape. If you release the cover

while it is stretched, you may be injured because it is wound up with

great force.

Therefore, if you release the roll cover, hold it by your hand so that

it is wound up slowly.
