With the JSUSP connector unhooked, check the resistance
between the carbon brushes is lower than 20 Ω, with the tester.
-When the resistance is 20 Ω or higher;
It is possible that the contact between the spindle axis and

In this case, repeat the operations of the step 1 through 5.
-When the resistance remains at 20 Ω or higher after repeating
the operation;
Contact your nearest Disco Service Office.
