Discover the key maintenance schedule for mini excavators to extend lifespan and reduce downtime. Follow expert tips for daily, 250-hour, 500-hour, and 1000-hour servicing to keep your Infinity mini excavator in top condition.
Why Regular Maintenance is Essential
Mini excavators are valuable assets for construction, landscaping, and excavation projects. Whether you own a 1-ton compact excavator or a 3-ton model like the Infinity FE930, proper maintenance ensures optimal performance, lower repair costs, and extended machine life. Following a structured maintenance schedule can significantly impact your machine’s efficiency and longevity.
Daily Checks: Before and After Each Operation
To prevent unexpected failures, conduct these daily inspections:
• ✅ Check engine oil, hydraulic oil, and coolant levels.
• ✅ Inspect air filters for dust buildup.
• ✅ Look for leaks in hydraulic hoses and connections.
• ✅ Examine tracks or tires for wear and tension.
• ✅ Grease all pivot points for smooth operation.
Routine Maintenance Schedule
1. 250-Hour Maintenance (Monthly Checkup)
• Replace engine oil and oil filter.
• Clean or replace the air filter.
• Inspect and clean the fuel and hydraulic filters.
• Check radiator and cooling system for debris.
• Ensure all bolts and connections are tightened properly.
2. 500-Hour Maintenance (Quarterly Service)
• Replace hydraulic oil filter.
• Change the fuel filter.
• Check battery condition and terminals.
• Inspect engine belts for tension and wear.
• Clean the cooling system thoroughly.
3. 1000-Hour Maintenance (Semi-Annual Overhaul)
• Replace hydraulic oil (especially in larger models like the Infinity FE930).
• Change final drive and swing motor gear oil.
• Inspect and replace worn hydraulic hoses.
• Check for excessive play in the boom, arm, and bucket joints.
4. 2000-Hour Maintenance (Annual Inspection & Rebuild Check)
• Perform a complete inspection of the hydraulic pump and cylinders.
• Replace old hoses and seals to prevent leaks.
• Service or replace the turbocharger (if applicable).
• Check and adjust the track tension.
How Long Can a Mini Excavator Last?
With proper maintenance, a high-quality mini excavator like the Infinity FE918 can last 8-10 years or over 10,000 operating hours. Factors like workload, operating conditions, and maintenance frequency determine its lifespan. Regular servicing minimizes downtime and maximizes return on investment.
Common Maintenance Mistakes to Avoid
❌ Ignoring small leaks – They can turn into costly repairs.
❌ Skipping hydraulic oil changes – Dirty oil leads to system failures.
❌ Overlooking track tension – Loose tracks wear out faster.
❌ Running the engine on low coolant – Leads to overheating and engine damage.
