1.2 MAGNET PLATE
Check the external view of the coil slider and maintain the coil slider
as described below.
Periodic checking of the external view
Check the external view at least once in every month. By making a
frequent check at short intervals, you can protect against trouble
beforehand.
When a magnet is exposed or floating
Replace the magnet plate immediately. If the magnet plate is used
without being replaced, a failure can occur.
When the resin is cracked or chipped
Replace the magnet plate as soon as possible. If the magnet plate is
used without being replaced, a failure can occur.
When the resin on the magnet plate surface has a flaw
If a flaw in question is a slight scratch, and no magnet is exposed, the
use of the magnet plate can be continued. If a magnet is exposed,
replace the magnet plate immediately. If a flaw is caused by foreign
matter caught in the gap between the coil slider and magnet plate,
remove the foreign matter immediately, and take measures to prevent
foreign matter from being caught in the gap.
Deformed or lost mounting screws
By using new mounting screws, secure the magnet plate tightly.
Play in assembly
If there is play although the mounting screws are tightened firmly,
replace the magnet plate immediately after checking that the play is
not caused by the machine. If the magnet plate is used without being
replaced, a failure or accident can occur abruptly.
