Maintenance starts with an asset and operating baseline, not an unconditional repair promise.

Scope, schedule, response, spare parts, site access, and service targets are defined in each project proposal or contract.

Service records separate symptoms, impact, diagnosis, actions, retest results, and follow-up.
