Hi there,
I has the window with S795-28 28B Channel Balances which were very old (more than 10 years). It works but moved slowly and heavily.
I sprayed some lubricant oil. It made a loud noise such as the friction between spring and the string when I opened and closed the window. It still works well but the noise. Do you know what happened and how to remove the noise from the Channel Balance or I need to replace them.
Thank you in advance for any advise and suggestion.
