Generator servicing: what a service covers and how often
1 November 2026 · Amptex Projects
A generator only earns its keep when the power fails, which is the worst time to find out it won't start. Regular servicing is how you avoid that.
How often should a generator be serviced?
Follow the manufacturer's schedule for your model, which is usually set by running hours or time, whichever comes first. A unit that runs often will reach its service interval faster than one that stands idle. If you've lost the manual, give us the make and model.
What a service typically covers
- Engine oil and filters, in line with the manufacturer's schedule.
- Fuel system and battery checks.
- Coolant on water-cooled units.
- Belts, hoses and connections.
- A test run, including how the unit takes the load.
What to check between services
- Fuel level, and how old the fuel is.
- Any leaks under the unit.
- Ventilation and exhaust clear of windows and doors.
- A short test run, following the manual.
Signs it needs attention now
Book a repair if the generator won't start, cuts out or drops the load. We repair units whoever installed them, and our electricians check the changeover at the DB board too.
