Is there a recommended maintenance schedule for the machines?

Routine maintenance will make your machine operate smoothly for a very long time! Each machine is different, but as a general rule, we recommend cleaning and inspecting cables/belts for tension. Throughout the weeks and months, it is best to inspect nuts and bolts for tightness, as well as cleaning rods and adding lubricant to sliding parts, bearings, etc. Depending on how often you use your machine, you may want to consider replacing cables, belts, and connecting parts as needed. (usually once per year).
