6. Risoluzione Dei Problemi

This section addresses common issues you might encounter with the Stanley N830-311 Double Clevis Link.

• Issue: Pins are difficult to remove or insert.
  Soluzione: Check for dirt or debris obstructing the pinholes. Clean the pins and clevis thoroughly. If there is visible deformation, the link may be damaged and should be replaced. A light lubricant can also assist.
• Issue: Clevis link appears bent or deformed.
  Soluzione: This indicates the link has been subjected to excessive load or impact. Immediately remove the link from service and replace it. Do not attempt to straighten or reuse a deformed link.
• Issue: Visible rust or corrosion.
  Soluzione: While zinc-plated for corrosion resistance, prolonged exposure to harsh conditions can lead to rust. Clean the affected areas. If corrosion is severe and compromises the structural integrity, replace the link.
• Issue: Chains are not seating properly in the clevis.
  Soluzione: Ensure the chain links are of the correct size (compatible with 5/8" clevis). Check for any foreign objects or deformation in the clevis slots or chain links.
