When it comes to maintaining precision tools like the 2M2 key cutting machines, a common question among locksmiths is: "What type of lubricant should be used for the machine parts, and how often should it be applied?"

The answer might surprise you: No lubricant is required.

Unlike some traditional mechanical equipment, the 2M2 series—including the TANK 2 PRO—is designed to operate efficiently without the need for external grease or oiling on its main components. In fact, applying unnecessary lubricants can sometimes attract dust and metal shavings, leading to buildup that might interfere with the machine's precision.

The Key to Maintenance: Regular Cleaning Instead of lubricating, the most important maintenance task is regular cleaning. Keeping the machine free of metal debris ensures smooth operation and extends the lifespan of the cutters and probes.
