can be moved to a spindle that rotates in the
opposite direction, as long as it is in a useable
condition. The discs are not repairable and
must be replaced if severely damaged or worn.

If holes appear in a disc, replace the disc
immediately. Do not attempt to repair the
discs. Always use factory replacement
