This annual preventive maintenance checklist is designed for emergency Caterpillar generator sets. It covers required tools and safety guidelines (including lockout/tagout), then guides technicians through comprehensive inspections and service tasks: visual walk‑around, cleaning, electrical connection checks, coolant level and sampling, belts and hoses, zinc rod inspection, radiator and water pump service, air intake cleaning and filter replacement, fuel system draining and filtration, bearing lubrication, oil sampling and changes, valve lash checks, protective devices, and charging system verification. It also includes battery electrolyte and specific gravity checks, full‑load operational testing on a load bank for one hour, vibration measurement, infrared thermography (CM‑0002), insulation testing (CM‑0003), temperature logging, safety shut‑off validation, and post‑run leak checks, ensuring reliable standby power and regulatory compliance.
