A diesel generator is a crucial investment for businesses, industries, and events that require a reliable power source. Whether used for standby power, continuous operation, or emergency backup, your generator must be properly maintained to ensure it runs efficiently when you need it most.
Why Diesel Generator Maintenance is Essential for Reliable Power
At Generator Hire Sales & Service, we know that regular diesel generator maintenance is not just recommended—it’s essential. Neglecting servicing can lead to unexpected failures, costly repairs, and a shorter generator lifespan. Here’s why ongoing maintenance is critical and how our expert team can help keep your generator running at its best.
1. Prevent Unexpected Breakdowns
Generator failure during a power outage can lead to business downtime, financial losses, and serious safety risks. Regular servicing helps catch small issues early and prevents them from becoming major faults.
Common causes of generator failures include:
- Battery failure – A weak or dead battery is one of the most common reasons generators fail to start.
- Fuel contamination – Degraded diesel can clog filters and damage injectors.
- Coolant leaks & overheating – Can lead to catastrophic engine damage.
- Blocked air & fuel filters – Reduce efficiency and increase fuel use.
Solution: Our generator maintenance plans include full inspections, battery checks, fuel testing, cooling system servicing, and filter replacements to keep your equipment in peak condition.
2. Maximise Generator Lifespan & Efficiency
A well-maintained diesel generator can last for decades. Regular maintenance prevents unnecessary wear, reduces fuel consumption, and avoids costly replacements.
Key maintenance tasks we provide include:
- Oil & filter changes – Prevent engine wear and extend lifespan.
- Load bank testing – Confirms your generator can deliver its rated capacity.
- Cooling system inspections – Prevent overheating and damage.
- Routine checks – Identify wear, leaks, or potential failures early.
We tailor maintenance plans to suit your generator’s load demands and working environment.
3. Prevent Wet Stacking & Carbon Buildup
Wet stacking occurs when a generator operates under light load for extended periods, causing unburnt fuel to build up in the exhaust system. This reduces performance and leads to costly repairs.
Common symptoms of wet stacking:
- Black smoke from the exhaust
- Carbon deposits and unburnt fuel in the exhaust
- Reduced engine performance over time
Solution: We perform on-site generator testing using portable Sephco resistive load banks to simulate real-world loads and burn off unburnt fuel. After testing, you’ll receive a detailed Load Test Report confirming your generator’s performance.
4. Maintain Fuel Quality & Prevent Contamination
Stored diesel fuel can degrade over time. Without testing and treatment, this can cause clogs, injector damage, and engine failure.
Typical fuel issues include:
- Water contamination – Promotes microbial growth and corrosion.
- Sediment buildup – Blocks filters and injectors.
- Oxidation – Thickens fuel and reduces combustibility.
Our fuel management services include:
- ✔ Regular fuel testing and filtering
- ✔ Tank cleaning and inspections
- ✔ Self-bunded diesel fuel tank solutions for safe, clean storage
