1.1 COIL SLIDER
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.
Checking of water and oil
Check if the coil slider is exposed to water or oil ceaselessly. If so, the
insulation can gradually degrade, reducing the life of the motor
remarkably. If such a state lasts, consider a structure that prevents the
coil slider from being exposed to water and oil.
Chipped resin
If the material inside the coil slider is exposed because of chipped
resin, replace the coil slider immediately. If the resin is chipped but
the inside material is not exposed, the use of the coil slider can be
continued. However, frequently check if the chipping of the resin gets
worse.
Cracked resin
If the resin is cracked, replace the coil slider immediately. If the coil
slider is used without being replaced, a failure (such as insulation
degradation) can occur abruptly.
Peeled cable sheath and terminal crack
If the material in question is replaceable, replace it immediately. If the
material in question is directly built into the main coil slider unit, it is
not replaceable. In this case, replace the coil slider. However, by
patching the trouble, the materiel in question may be used only
temporarily.
Play in assembly
If there is play although the mounting screws are tightened firmly,
replace the coil slider immediately after checking that the play is not
caused by the machine. If the coil slider is used without being
replaced, a failure or accident can occur abruptly.
