Maintenance:

  • Yale Spring balances are designed to require only minimal maintenance. Balances are best protected by being operated at least once a month. Should balances not be operated for long periods, particularly lower sash balances, then apply a light coat of high-quality water-resistant multi-purpose greases to the extended helix rod routinely to ensure optimum balance performance. Tubes can be cleaned with a damp cloth
