Safety Precautions for Lambda Chain

  • Do not use Lambda Chain if the chain will come in direct contact with food or where coating flakes or wear dust can contaminate food. Also, in non-food applications, appropriately cover the chain or contact a Tsubaki representative about chain selection if using in environments where coating flakes or wear dust present problems. Though nickel is not subject to the japan Food Sanitation Law or the Industry Safety and Health Law, plating on sliding parts can peel.
  • Do not use Lambda Chain where there is the possibility of exposure to chemicals, water, or cleaning/degreasing vapors.
  • Oil might spatter depending on the usage conditions.
  • Please be aware that NSF H1 non-compliant rust prevention oil and assembly oil may be present on the chain.
