When a diesel generator inspection is performed without a structured guide, critical items get missed. One technician checks the oil, another checks the coolant, but nobody verifies the transfer switch operation or documents the hour meter reading. This inconsistency creates gaps that turn into failures—failures that always seem to happen during the worst possible moment: an actual power outage.
OXmaint transforms generator inspections from memory-dependent checklists into standardized, documented procedures. Every inspection follows the same comprehensive guide, every reading is captured digitally, and every report is generated automatically. Your team builds a complete operational history that predicts problems before they cause downtime.
The 5 Critical Inspection Categories
01
Fluid Systems
Engine oil level and condition, coolant level and mixture, fuel level and quality, hydraulic fluids where applicable.
02
Electrical Systems
Battery voltage and connections, charger operation, control panel indicators, wiring integrity, and grounding.
03
Mechanical Components
Belt tension and condition, hose integrity, exhaust system, mounting bolts, vibration isolators, and enclosure.
04
Control & Safety
Emergency stop function, overspeed protection, low oil pressure shutdown, high temperature shutdown verification.
05
Transfer Equipment
ATS operation, utility sensing, transfer timing, load shedding sequence, and return-to-normal function.
Comprehensive inspections across all five categories ensure nothing slips through the cracks. Schedule a demo with OXmaint to see how digital inspection guides transform reliability.
Stop Relying on Memory
OXmaint's inspection guide ensures every technician performs the same comprehensive check, every time—with automatic documentation and trend tracking.
A generator inspection is more than a walk-around. It is a systematic evaluation that captures current condition, identifies emerging issues, and documents compliance. OXmaint digitizes this entire workflow from assignment to final report.

Industry Applications
Critical Sectors for Generator Inspection Programs
Healthcare Facilities
NFPA 110 requires documented weekly inspections and monthly tests. OXmaint provides audit-ready compliance records.
Fueling stations, rail yards, and airports need documented backup power readiness for safety-critical operations.
Operational Continuity
Templates Ready to Deploy
OXmaint includes pre-built inspection templates for diesel generators that meet NFPA 110, Joint Commission, and manufacturer requirements. Customize or use as-is.
NFPA 110 requires weekly visual inspections covering fluid levels, battery condition, and general cleanliness. Monthly inspections should include a test run of at least 30 minutes. Annual inspections require comprehensive testing including load bank tests. OXmaint automates scheduling for all inspection frequencies.
What should be included in a generator inspection report?
A complete inspection report should include asset identification, date/time, inspector name, all checklist items with pass/fail status, measured readings (voltage, pressure, temperature), photographs of any deficiencies, corrective actions required, and follow-up work orders. OXmaint generates all of this automatically.
Can OXmaint inspection reports satisfy NFPA 110 requirements?
Yes. OXmaint inspection templates are designed to meet NFPA 110 requirements for Level 1 and Level 2 emergency power supply systems. Reports include all required documentation elements and provide timestamped digital records that satisfy AHJ (Authority Having Jurisdiction) audit requirements.
How do I track inspection trends over time?
OXmaint automatically tracks all inspection readings and flags declining trends. For example, if battery voltage drops over consecutive inspections, the system alerts maintenance before failure occurs. Dashboard reports show inspection completion rates, common deficiencies, and asset health trends.
