Usage-based intervals are based on manufacturer guidelines and industry benchmarks. Mileage is used for road vehicles; operating hours for plant and equipment.
Calendar maximums apply regardless of usage. Fluids degrade, seals dry, and corrosion progresses even on lightly used assets. Always service within the calendar limit.
Environment multipliers reflect how significantly operating conditions affect wear. A forklift in a clean warehouse lasts 2× as long between services as one in a foundry.
Disclaimer: These are general guidance intervals based on industry standards. Always follow the original equipment manufacturer (OEM) recommendations for your specific asset and consult a qualified engineer for safety-critical systems.
