How often should my mechanical clock movement be oiled and cleaned?
It is recommended that your clock movement be oiled every two years from the date of purchase and thoroughly cleaned every five to ten years depending upon climatic conditions. Extremely dry, humid or salty air, hot or cold may necessitate more frequent servicing. Howard Miller does not recommend that you service your clock yourself. Contact an authorized Howard Miller Service Center as found at this internet site. Cleaning and oiling are not covered under warranty.
