Maintenance intervals, fluids and wear limits

What to service at 250, 500, 1,000 and 2,000 hours, how to choose fluids, and the wear limits that tell you when a component is finished.

Most of the repairs in the troubleshooting section are cheaper to prevent than to fix, and a surprising share of premature failures trace back to a service interval that was followed on paper but not in substance — the wrong fluid, a filter changed without the strainer, grease applied to the fitting but not the pin. These guides cover the intervals, the fluids and the wear limits, and explain what each one is actually protecting.
