Why Central Pneumatic 42202 housing heats during use?
- T
  Tiffany GrimesAug 23, 2025
  If the housing of your Central Pneumatic Ultrasonic Jewelry Cleaner heats up during use, it could be due to worn parts, which would require a qualified technician to inspect the internal mechanism and replace parts as needed. Alternatively, long periods of continuous use can cause overheating. To resolve this, use the cleaner intermittently, allowing cool-off periods.
