Preventative maintenance isn’t just a checklist - it’s a good strategy. Performing regular visual and operational checks helps to keep small problems under control.
Operator checks on a daily basis are part of good maintenance practice. These checks, along with in-depth weekly and monthly inspections of your engine, will help flag up potential problems before they lead to major repairs.
1. Stick to the service schedule
Follow the recommended service intervals in your engine manual. Regular oil changes, filter replacements, and inspections are essential to prevent wear and tear
The Perkins Operations & Maintenance Manuals (OMMs) provide all the information you need to keep your engine running properly day in, day out. They include details on regular maintenance intervals together with technical data and guidance.

2. Regular oil and filter changes
Clean oil reduces wear and keeps components running smoothly.
3. Coolant system care:
Flush and refill coolant as recommended to prevent overheating.
4. Use genuine Perkins parts:
For true peace of mind, always choose genuine Perkins filters, fluids, and components. They’re engineered specifically for your engine and help maintain optimal performance and warranty coverage. For the correct fit and function, choose genuine Perkins parts.
5. Monitor fluid levels
Check engine oil, coolant, and fuel levels regularly. Low or dirty fluids can lead to overheating, poor lubrication, and reduced efficiency.
6. Keep it clean
Ensure the engine and surrounding area are free from debris, dust, and oil buildup. A clean engine runs cooler and is easier to inspect for leaks or damage.
7. Inspect belts and hoses
Look for cracks, fraying, or signs of wear. Replace any damaged components promptly to avoid breakdowns
8. Check battery health
A weak battery can affect engine starting and electrical systems. Clean terminals and test voltage regularly.
9. Watch the air intake system
Ensure the air filter is clean and the intake system is free of obstructions. A clogged filter reduces fuel efficiency and power output. Clean filters improve efficiency and reduce strain.
10. Keep software updated
If your engine is equipped with electronic controls, ensure firmware updates are applied. These can improve performance and diagnostics.
