I. Pre-Operation Preparation
1. Personnel Qualifications
Operators must be certified and familiar with the equipment's performance and emergency response procedures.
Untrained personnel can easily misadjust parameters, leading to uneven compaction or equipment damage.
2. Equipment Inspection
Key Components: Check the engine oil level, brake system sensitivity, tire pressure (refer to the equipment manual for standard values), and roller surface cleanliness.
Hydraulic System: Verify that there are no leaks, the oil level is within the scale, and the oil is clear and free of impurities.
Safety Devices: Test the emergency stop button and warning lights for proper function.
3. Environmental Assessment
Clear the work surface from obstructions and assess soil moisture (air it out if it's too wet; water it if it's too dry).
II. Operating Instructions
1. Starting and Driving
After starting, run the machine at no load for 3-5 minutes and observe if there are any abnormal alarms on the instrument panel. Maintain a constant speed while driving (recommended speed: 1.5-2 km/h for initial compaction, 2-3 km/h for secondary compaction). Avoid sharp turns or sudden braking.
2. Compaction Techniques
Layered compaction: Each layer should be ≤30 cm thick, following the principle of "light first, heavy later, slow first, fast later."
Overlap Width: Adjacent compaction strips should overlap by 1/3 of the wheel width to ensure no pressure loss.
Vibration Control: Use low frequency and high amplitude for soft soils and high frequency and low amplitude for hard soils.
3. Safety Distance
No one is allowed to stand within the operating radius, and coasting in neutral is prohibited when going downhill.
III. Maintenance
1. Daily Maintenance
Clean off any debris (such as asphalt) from the rollers and inspect tire wear (tread depth <3mm requires replacement).
Drain any accumulated water in the fuel tank after operation to prevent oil line corrosion.
2. Regular Maintenance
Weekly: Replace the oil filter and lubricate the joints. Every 500 hours: Replace the hydraulic oil and calibrate the vibration system balance.
3. Long-term Parking
Park on a flat surface, place wooden blocks under the tires to prevent deformation, and disconnect the negative terminal of the battery.
IV. Emergency Procedures
Sudden malfunction: Immediately turn off the engine and apply the brakes. If there is a hydraulic leak, use absorbent cotton to remove it.
Personal Injury: In the event of a crush accident, disconnect the power before rescuing to avoid secondary injuries.
