Working chair repaired



The coil protecting thermal fuse was put on adequate position on field coil component replacing the parts bypassed for temporally countermeasure a few years ago. The cause of the thermal fuse cut was water leaking on printed circuitry pattern. Now the original condition is acquired again as a new protection.
All the functions on oil pressure lines are OK, checked!
The price of a thermal fuse part is 100 yen in all, but the replacement procedure by some professional engineer costs at least 15,000 yen including service man's travel fee.
