The CoLibrì Automatic Book Covering machine requires minimal maintenance. The only part requiring routine maintenance is the Welding Bar. A Welding Bar should be inspected after 5,000 cuts to ensure it is welding and trimming properly.
If after 5,000 cuts (see machine display) the machine does not appear to be welding and trimming properly, you should replace the welding bar.
Note: You must choose the correct welding bar for your machine.
