Daily Maintenance Guide
For remote mining areas and long-term self-power generation sites, organize pre-start inspections, operating hour maintenance, ATS and load tests, alarm records, repair information and spare parts preparation. Let the site know what to check every day, when to perform maintenance, and what information to leave when something goes wrong.
Maintenance logic
The units in remote mining areas have been operating for a long time, and on-site judgment cannot be based solely on experience. Daily inspections, maintenance based on operating hours, regular electrical inspections, keeping alarm and operating records, and preparing commonly used spare parts in advance can allow engineers to diagnose problems faster and reduce minor failures from leading to long-term shutdowns.
To judge maintenance, first check whether the fault affects drainage, crushing, ventilation, communications or camp power supply. When critical loads are affected, processing priority is higher than ordinary maintenance items.
Long-term self-generated power cannot be maintained only according to the date. Operating hours, load factors, dust, rainy weather and fuel quality all determine the inspection intervals for filters, oil, belts and cooling systems.
Alarm codes, controller photos, operating hours, fuel consumption, load changes and maintenance actions are the basis for engineers' remote judgment. Without a record, you can only guess from scratch every time.
In remote mining areas, even a small unavailable part can cause a long delay. Filters, belts, sensors, batteries, controllers, AVRs and common electrical components should be prepared in advance based on the equipment model and downtime risk.
Maintenance rhythm
Mining area units operate for a long time, and maintenance cannot rely on verbal reminders. It is recommended to divide inspection actions into five categories: daily, weekly, monthly, by operating hours and after failure, and fix the recorder, record content and processing results. In this way, the equipment person in charge, on-site electricians and engineers can see the same set of records and diagnose problems more quickly.
Appearance, oil, oil and water leakage, controller alarm, battery, fuel level, operating sound and cooling and ventilation.
Terminals, grounds, belt tension, air cleaner, radiator surfaces, fuel tank sedimentation and operating record review.
Load testing, ATS or parallel logic, protection parameters, backup unit startup, cable temperature rise and critical spare parts inventory.
Engine oil, machine filter, diesel filter, air filter, coolant, oil-water separator and periodic maintenance items specified by the manufacturer.
Retain alarm, video, load, oil pressure, water temperature, voltage frequency and processing actions. Do not just reset and continue running.
Article combination
Each article revolves around an on-site action: what to watch, how to record, when to find an engineer, and which small risks cannot be postponed.
Maintenance 01
Many outages do not occur suddenly. Insufficient oil, oil leaks, loose belts, weak batteries, clogged radiators and controller alarms can often be seen before starting the engine.
Maintenance 02
Long-term spontaneous power generation sites, operating hours are closer to true wear than calendar dates. Filter elements, engine oil, fuel system, cooling system and belts should all be managed according to actual operating intensity.
Maintenance 03
The fact that the generator can start does not mean that the electricity has been stably delivered to the critical load. ATS automatic switching, low-voltage distribution cabinets, grounding, cables, circuit breakers, parallel control and load testing all need to be inspected regularly and recorded.
Maintenance 04
Many faults are not due to inability to determine, but due to incomplete on-site information. Controller photos, alarm codes, operating hours, load, oil circuit, voltage frequency and fault video can significantly shorten the remote judgment time.
Maintenance 05
The cost of remote on-site repair is not just the price of an accessory. Personnel presence, transportation, accommodation, waiting, buying the wrong parts, and repeated inspections all make minor glitches expensive.

Please try to explain the unit model, operating hours, daily operating hours, current load, alarm code, recent maintenance records, on-site photos and whether it affects critical loads.
Engineers will contact you soon to understand your questions and needs.
