This is scheduled for a complete overhaul.
Update: During my initial inspection, I noticed some missing springs and misaligned parts. The unit was fully disassembled, with every nut, bolt, screw, and washer taken apart. The parts were cleaned overnight, followed by meticulous hand cleaning. Afterward, I reassembled and adjusted everything, applying oil and grease where necessary. The unit has been tested and is functioning properly, now ready to be returned to its home.
