1. Daily Inspection

• Check the surface of the vibratory drum for cracks, deformation, or serious wear.
• Inspect the scraper to ensure it is in close contact with the drum surface to prevent asphalt or soil buildup.
• Check for oil leakage around the vibration chamber, bearing seats, and oil seals.
• Listen for abnormal noise during vibration; stop immediately if unusual sound occurs.

2. Lubrication and Vibration Oil Maintenance

• Use the specified vibration oil and change it strictly according to the working hours recommended in the manual.
• Before adding new oil, clean the oil chamber and drain the old oil completely.
• Check oil level regularly; maintain proper oil volume to ensure bearing lubrication and cooling.
• Use genuine lubricating oil to protect bearings and gears from premature damage.

3. Bearing Maintenance

• Vibratory bearings work under heavy impact and must be kept in good lubrication.
• Follow the grease injection schedule and use special high-temperature resistant grease.
• Do not over-grease, as it may cause overheating and seal failure.
• If vibration becomes weak, uneven, or noisy, inspect and replace bearings in time.

4. Cleaning and Protection

• Clean the drum surface after each shift, especially when working on asphalt.
• Keep the drum free of hardened materials to avoid uneven compaction and surface damage.
• When not in use for a long time, park the roller on a flat site and avoid long-term pressure on one side of the drum.

5. Avoid Improper Operation

• Do not start or stop vibration while the roller is stationary to prevent damage to the vibration system.
• Avoid vibrating on hard ground such as concrete or stone to reduce impact load.
• Do not use the vibratory drum to push or hit obstacles.

6. Regular Maintenance Summary

• Check vibration intensity, oil seals, and bearing temperature regularly.
• Replace worn scrapers, oil seals, and gaskets in a timely manner.
• Keep maintenance records for better management and fault prevention.
