We service generators across Mamelodi, Nellmapius and Mahube Valley: petrol and inverter units run through load shedding at homes and salons, sets at spaza shops and car washes, and school, church and clinic standby sets that must start first time. Visits fit around trading and school hours.

Who needs it
Routine servicing in Mamelodi
Homes running a set every outage: Petrol generators
A small air-cooled engine holds little oil, so a few busy weeks of load shedding bring its oil change due.
Salons, spaza shops and taverns: Commercial generator services
Dryers, fridges and sound keep a set near full load, and a worn engine loses speed as each motor starts.
Car washes and workshops: Voltage problems
Pressure washers and compressors start under load; we check the set still holds its voltage when they do.
Schools and churches: Generator maintenance
Sets used a few times a term: fuel goes stale, the battery drains and rubber seals harden while they stand.
Clinics and the hospital: Load bank testing
Standby sets that cannot fail with the mains, so fuel, battery, charger and changeover are proven each visit.
Servicing
What a generator service in Mamelodi includes
On the small units that make up most of Mamelodi’s generators, the service centres on oil, plug, air filter and fuel, with an inverter’s output checked under real load. School and clinic sets also get the battery, charger and changeover tested.
- Engine oil and filter, with the fuel, air and water-separator filters
- Coolant level and condition, radiator, hoses and belts
- Starting battery load-tested, charger output and terminals checked
- Fuel system checked for leaks, water and contamination, tank to injectors
- Alternator, AVR, output connections and earthing checked
- Controller settings, alarms and hour meter recorded
- Test run under load: voltage, frequency and temperatures
- Changeover (ATS) operation confirmed where fitted
You get a written record of what was done and found. The full list is in our service checklist; generator servicing explains the work and a maintenance plan keeps it on schedule.

Plans
Maintenance plans for Mamelodi households, traders and institutions
Household plan: Residential generator services
Oil, plug and air filter changed by the hour meter, old petrol drained and the output tested.
Trading plan: Generator servicing
For salons, spaza shops, taverns and car washes: visits before opening, with the set’s size checked against what it now runs.
School and church plan: Generator maintenance
A service before each term or the festive season, and a test start between visits so a seldom-used set is proven.
Clinic plan: Load bank testing
A monthly run under load, charger and battery measured, the changeover tested and each visit written up for the facility manager.
Prevention
Faults a service in Mamelodi finds early
Most breakdowns here give notice. A service finds the oil low before the low-oil switch cuts the set mid-evening, petrol turning gummy before it blocks the jets, a scorched socket before the voltage fails, and a school battery too weak to crank before an outage proves it.
If the set has already stopped, our Mamelodi generator repairs page lists the faults we fix most. We service generators the same way in Silverton, Cullinan and Lynnwood and Faerie Glen, through our Pretoria East coverage and the Pretoria hub.

FAQ
Frequently asked questions
My inverter generator runs most evenings during load shedding. When is it due for a service?
When its running hours reach the manual’s interval, which at higher stages can be weeks away rather than a year. Note the hours each time it runs, or read its meter, and book as you near the figure.
Can you service the school generator during the holidays?
Yes, and the holidays suit it: the set can be stopped, drained and run under load with nobody in class. Book before term so stale fuel and a weak battery are dealt with ahead of the first outage.
Should I leave petrol in the portable while it stands between outages?
Not for long. Petrol goes stale within weeks and gums the carburettor. Buy enough for an outage or two, keep it in a proper container away from living rooms, and ask at the service how to lay the set up for a long rest.
Can a clinic or church in Mamelodi put its generator on a maintenance plan?
Yes: services by hours or months, test runs between visits and a record of each one. We work 24/7, so a clinic set can be tested when it disturbs patients least.
