Who needs it
Routine servicing in Alexandra
Households sharing one portable: Petrol generators
Run every evening for several rooms, a small air-cooled engine reaches its oil-change hours quickly.
Spaza shops and small retailers: Commercial generator services
Fridges and freezers on a set that must hold voltage as compressors cycle.
Taverns and eateries: Generator servicing
Long evening runs carrying lights, sound and cold drinks wear the oil, air filter and plug fastest.
Churches, schools and crèches: Generator maintenance
Sets used a few times a term, where stale petrol and a flat battery show up only in the outage.
Clinics: Battery not charging
A set that must start first time, with its battery, charger and fuel checked between runs.
Workshops and car washes: kVA sizing guide
Compressors and pressure washers load a set hard; the service checks it still holds when a motor starts.
Servicing
What a generator service in Alexandra includes
In Alexandra a service also looks at where the set stands and how its fuel is kept. Sets in tight yards and passages get their exhaust clearance and cooling airflow checked, and petrol kept in containers is inspected for water and age.
- 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.
Intervals
How often to service a generator in Alexandra
| Set and site | Typical use here | What decides the next service |
|---|---|---|
| Portable at a home with backyard rooms | Typical use hereEvery load-shedding slot, often near full load | What decides the next serviceRunning hours; a small sump makes oil the first item |
| Spaza or small shop set | Typical use hereThrough trading hours whenever the power fails | What decides the next serviceHours, with the air filter checked between services |
| Tavern or eatery set | Typical use hereLong evening runs during outages | What decides the next serviceHours in a busy month; plugs and filters wear early |
| Church, school or crèche set | Typical use hereA few runs a term, then stored | What decides the next serviceMonths: fuel goes stale and the battery drains as it waits |
| Clinic set | Typical use hereEvery outage, sometimes for hours | What decides the next serviceHours at higher stages, plus a monthly run under load |

Plans
Maintenance plans for Alexandra, by kind of site
Household plan: Residential generator services
Oil, plug and air filter changed by the hour meter, stale petrol drained and output tested on a shared portable.
Shop, tavern and eatery plan: Generator servicing
Visits before trading opens, with the set’s capacity checked against what it now carries.
Church, school and crèche plan: Generator maintenance
A service ahead of the busy months and a test start between visits, so a seldom-used set is proven ready.
Clinic plan: Load bank testing
Monthly runs under load, battery and charger checks, and a written record of each visit for the clinic’s management.
Workshop and car wash plan: Commercial generator services
Services by running hours, with checks that a starting compressor or washer will not stall the set.
Prevention
What an Alexandra service catches before the outage does
Most failures here give warning. A service finds the sump low before the low-oil switch stops the set mid-evening, petrol turning to varnish before it blocks the jets, worn brushes or a scorched socket before the voltage fails, and dust-packed cooling fins on a set pushed into a corner.
If the set has already stopped, the Alexandra generator repairs page lists the usual faults and what to send us. We service the same way in Sandton, Wynberg and Marlboro and Norwood and Orange Grove, and throughout the Sandton hub.

FAQ
Frequently asked questions
How often should the portable that powers our house and backyard rooms be serviced?
By its running hours, not the calendar. Shared between several rooms, it may run every slot near full load, so oil and plugs fall due fast. A simple log of hours run tells us when.
Our crèche generator hardly runs. Is a yearly service enough?
At least yearly, with a test start in between. Standing does its own damage: fuel varnishes in the carburettor, an electric-start battery loses charge and rubber seals harden. The service puts all three right.
Where should we keep petrol for the generator between outages?
In a proper fuel container, outside living and sleeping rooms, away from flames and out of children’s reach. Buy what one or two outages need; petrol kept for months goes stale and starts the next breakdown.
Can a clinic in Alexandra put its generator on a maintenance plan?
Yes: services by hours or months, monthly runs under load, battery and charger checks and a record of every visit. We work 24/7, so tests are timed around patients.
