Hand-held punching machines are sturdy tools but there are some simple guidelines to keep them in tip-top order.
Storage
Storing your punching machine in a case or tool box will not only keep it from accidental damage but it will also help to keep all the spare parts, dies, and punches together for easy access.
Lubrication
As with any piece of machinery or tool, if it has moving parts then it is advised to keep them well lubricated and maintained with some multi-purpose oil.
Replacement punches and dies
There may come a time when you need to replace your punches and dies, as wear and usage may eventually blunt them. You can purchase replacement punches and dies from your local supplier or hardware store.
