I. Pre-Operation Precautions
1. Personnel Qualifications and Training
Operators must be certified and receive regular refresher training (recommended every two years), focusing on understanding the hydraulic system, vibration mechanism principles, and emergency response procedures.
Untrained personnel can easily misadjust parameters, leading to engine overload or uneven compaction.
2. Equipment Inspection Checklist
Engine System: Check the oil viscosity (replace with low-temperature oil in winter), coolant freezing point, and battery charge (install a preheating device in cold regions).
Hydraulic System: Verify the oil level is within the mark and that the oil is free of emulsification (water content <0.1%).
Travel Mechanism: Ensure tire pressure tolerance is ≤ ±0.2 bar, and the drum surface is free of cracks or adhesions. II. Troubleshooting During Operation
1. Standardized Operating Procedures
After starting, run the machine at no load for 3-5 minutes. Observe the instrument panel for any abnormal alarms (if the hydraulic oil temperature exceeds 80°C, stop the machine for inspection).
Maintain a constant speed during compaction (1.5-2 km/h for initial compaction, 2-3 km/h for recompacting). Avoid sharp turns that could cause excessive drive shaft torque.
2. Environmental Adaptation
Low-temperature environments: Use -20°C diesel and install a fuel preheater to prevent wax buildup on the injectors.
Soft soil: Perform static compaction 1-2 times before activating vibration mode to prevent clutch damage.
III. Key Maintenance Points
1. Regular Maintenance Intervals
Daily: Clean any debris from the rollers and check the hydraulic oil line joints for tightness.
Every 500 hours: Replace the hydraulic oil filter (ISO VG46 anti-wear hydraulic oil is recommended). Seasonality: Check the electrical system for waterproofing during the rainy season and replace the antifreeze in winter (freezing point below -30°C).
2. Wear Parts Management
Refill the vibration bearing with lithium-based grease (NLGI Grade 2) every 2,000 hours. Replace if wear exceeds 1mm.
Check belt tension monthly. Adjust if deflection deviation exceeds 15mm.
IV. Intelligent Monitoring and Recording
Install a compaction sensor to monitor the rolling path and density in real time (automatic alarm if deviation exceeds 5%).
Create an electronic maintenance file to record fault codes and solutions (e.g., engine E03 fault requires turbocharger inspection).
