3. Bolt connection at the mouth of the copper strip broken, coil leading out end head and the last turn are fixed at a copper double, to strengthen the mechanical stability.

4 connecting bolts are loose, can be added to the spring or other brake coil, the bolt is not less than M8, the large traction motor can be used for two bolts fastening.

At the film not scrape or surface oxidation of 5 bolts, can be re tighten the bolt and insulated conductive contact surface after sanding.

6 copper breaks lead to bad welding, or to replace the coil to be rewelded.
