Fault Symptoms (Q&A)
QUESTION: Why does the locking ring turn black?
ANSWER: During the grinding of meat, various environmental and chemical factors come into play that can lead to oxidation or corrosion of some components of the meat grinder; it is an inevitable process. For this model of meat grinder, only an aluminum closing ring is provided; there are no original variants in steel or cast iron.

QUESTION: Why can't I lock the cutting parts inside the holder?
ANSWER: Check that the locking ring is not cracked or broken, or that the threading in the accessory housing body is not excessively damaged. Also, check for any residues from processing that may be caked on and prevent the proper tightening of the locking ring.

QUESTION: Why can't I remove the locking ring?
ANSWER: After each use, it is recommended to immediately remove the body and clean the accessories. If they are not cleaned, residues may harden and make disassembly complicated or impossible.

Maintenance Tips and Longevity
To preserve the lifespan of your Reber locking ring, follow these simple precautions. First, never tighten the component with excessive force: it should be secure, but forcing the closure can strip the thread or crack the metal (especially if cast iron). Second, cleaning is essential: after each use, wash and especially dry the ring immediately and thoroughly. We strongly discourage washing in the dishwasher; aggressive detergents oxidize and blacken the locking nut. Instead, we suggest applying a small amount of food-grade oil or lubricant to the threading every 2-3 months, which can help prevent future jams.

What is the purpose of the front ring?
The locking ring is a fundamental part for the proper functioning of your meat grinder. Its main function is to securely lock the perforated plate and the knife against the worm screw inside the body of the meat grinder, ensuring the correct cutting adherence. A ring in good condition allows the meat to be ground evenly, preventing the grinding group from moving or the motor from dangerously straining due to misalignments. Additionally, over time the locking ring may wear out, so it is advisable to replace it to maintain a high level of hygiene of the product.
