Core Maintenance Protocols: Beyond Basic Repairs
Modern rear-loading compactors compactors implement a structured maintenance architecture that integrates precision engineering with proactive care, ensuring optimal performance and extended service life through systematic inspection protocols and predictive maintenance strategies.
Hydraulic System Integrity
• Daily oil level verification with all cylinders fully retracted and packer closed
• Climate-specific hydraulic fluids: #46 anti-wear (standard) / #32 low-temp (below 0°C) - strict prohibition of mixing
• 10μm filtration during refilling + initial 3-month oil/filter replacement, then 6-month cycles
• Complete oil drainage with tank cleaning and air purge through idle operation after refilling
Mechanical Reliability Assurance
• 1-2 weekly calcium-based grease injections for guide rails and rotating shafts until new grease emerges
• Biannual high-pressure hose replacement with immediate replacement if cracking/aging/bulging detected
• On-demand seal replacement when cylinder leakage occurs
• Regular inspection of hydraulic system sealing integrity
