Repairing and servicing a portable diesel generator

Keep Your Backup Power Dependable & Operational

When grid power drops or storms sever coastal power lines, you need complete certainty that your backup generator will start on the first crank.

The Restorers provides professional maintenance, fault diagnostics, and mechanical/electrical repairs for petrol and diesel generators. We handle oil and filter changes, carburetor ultrasonic cleaning, spark plug replacements, battery health tests, and automatic transfer switch (ATS) safety checks.

Our technicians troubleshoot hard-starting units, uneven voltage outputs, AVR failures, and ensure compliant changeover switches with legal interlocks to prevent dangerous grid back-feeding.

Frequently Asked Questions

Got questions about our services in Knysna? Here are answers to some of the common inquiries we receive.

How often should a standby residential generator be serviced? ↓

Standby generators should be serviced every 50 to 100 operating hours or at least once every 12 months (whichever comes first) to prevent stale fuel varnishing, oil breakdown, and dead starter batteries.

Why won't my generator start after sitting idle for several months? ↓

In Knysna's humid climate, modern petrol degrades within 60–90 days, leaving gummy deposits in the carburetor jets. The starter battery also naturally discharges. We clean fuel systems and install battery trickle chargers.

Can you legally connect my generator into my home's main DB board? ↓

Yes. Connecting a generator to your DB board requires a certified manual or automatic changeover switch with mechanical interlock and a neutral-earth bonding relay to comply with SANS 10142 codes.
