Generator Servicing · Gauteng
Generator Servicing Across Gauteng
Generator servicing is a planned onsite visit: oil, filters, coolant, the battery and a running check. It is not a breakdown repair. If the set has already failed, that job is booked as generator repairs.
- Oil & filter change
- Coolant system check
- Battery & charging test
- Full load test
The Service
Scheduled generator servicing — one visit at a time
Generator servicing is individual, scheduled service work — a booked visit to inspect and service the machine you have, not an ongoing maintenance programme. If you want recurring visits and tracked intervals, that belongs on the maintenance page.
What we do on the day depends on the model, fuel type and hours. Typical items include oil, filters, coolant and cooling checks, battery testing, belts, a fuel-system inspection, controller checks, and ATS/changeover checks where they apply. We do not apply every item to every generator.
Intervals should follow the manufacturer schedule for your set. Standby machines that sit between outages are often serviced at least annually; prime-power sets need more frequent visits. We help you choose a practical date. We do not invent a single hour figure for every brand.
Servicing is done onsite across Gauteng. Before you book, it helps to have the brand, size if known, diesel or petrol, running hours if shown, and any recent alarms.

What's Included
What a generator service typically includes
01
Engine oil and oil filter
Where the service schedule calls for it, oil is drained and replaced with a lubricant matched to the engine.
02
Fuel and air filters
Fuel and air filters are inspected and replaced if they are due or restricted. Different models use different filter sets.
03
Coolant and radiator
Coolant level and condition, hoses, and a radiator look-over — important on standby diesels that sit, then run hot.
04
Battery, belts and charging
Battery condition, terminals, belt condition and charging output, so the next auto-start is not lost to a flat battery.
05
Fuel system and controller
A visual fuel-system check and controller look-over. ATS or changeover operation is checked where the site has one.
06
Inspection and a running test
A general inspection, then a run after the service. Not every visit is a full load-bank test — that is a separate service.
Service Intervals
How often should a generator be serviced?
Follow the manufacturer
The model plate and handbook set the real interval. We work to that, not a generic slogan.
Standby sets
Often an annual service if hours are low, or sooner when loadshedding hours add up.
Prime or high-hour sets
More frequent servicing based on hours, load and how dirty the site is.

Their attention to detail during our 500-hour major service was incredible. They meticulously checked valve clearances, tightened mounts, and calibrated the AVR, making the machine run noticeably smoother.
Google Review
Very thorough scheduled servicing.
Common Questions
Generator servicing — questions
What does generator servicing include?
Items appropriate to that machine — commonly oil, filters, coolant and radiator checks, battery testing, belts, a fuel-system look-over, controller checks, and ATS/changeover checks where fitted. The list is not identical on every visit.
How often should a generator be serviced?
Follow the manufacturer schedule for that engine. Hours and calendar time both count. The short answer is on the how-often guide. This page is the booked service visit, not the interval explanation.
Can generators be serviced onsite?
Yes. Scheduled servicing is done at your premises across Gauteng. You do not need to move the machine for a routine service.
What information should I provide before booking?
Brand and model if known, kVA if known, diesel or petrol, the site location, a preferred date, and any alarms or leaks you have noticed.
Still unsure what the fault is? Call or WhatsApp 082 057 4605 for onsite diagnosis.
