Regular maintenance is essential for extending the service life of road rollers and ensuring construction efficiency. Below is a maintenance schedule categorized by time/operating hours, along with core operational guidelines.

I. Daily Maintenance (Every 8-10 Operating Hours / Daily)

Key Focus: Preventive checks and minor fault elimination

1. Cleaning

• Remove adhered materials (asphalt, mud) from steel wheels/tires.

• Check engine compartment for dust accumulation to prevent overheating.

2. Lubrication

• Apply grease to pivot points and bearings (e.g., steering bearings, vibration drum bearings).

3. Fluid Level Checks

• Verify engine oil, hydraulic oil, and coolant levels are within standard ranges.

4. Fastener Inspection

• Check for loose bolts and nuts (especially vibration wheel bolts).

5. Safety Device Testing

• Ensure lights, horn, and braking system are functioning properly.

II. Weekly / 50-Hour Maintenance

Key Focus: In-depth system inspection

1. Transmission System

• Check gearbox oil level and inspect gear oil for metal particles (first oil change at 500 hours).

2. Vibration System

• Test vibration frequency stability and listen for abnormal noises from eccentric blocks.

3. Tires/Steel Wheels

• Ensure uniform tire pressure (standard for pneumatic tire rollers: 500–700 kPa).

• Inspect steel wheel welds for cracks.

4. Filters

• Clean air filter (blow out dust); replace if heavily soiled.

III. Monthly / 250-Hour Maintenance

Key Focus: Critical component servicing

1. Oil and Filter Replacement

• Engine oil (first change at 250 hours, then every 500 hours).

• Replace oil and fuel filters simultaneously.

2. Hydraulic System

• Check hydraulic oil cleanliness (ISO 18/15 or lower); replace if necessary.

• Inspect hydraulic lines for leaks.

3. Electrical System

• Check battery terminals for corrosion and wiring for wear.

IV. Quarterly / 500-Hour Maintenance

Key Focus: Core component overhaul

1. Vibration Drum Maintenance

• Replace drum lubricant (recommended: GL-5 85W-90).

• Check bearing wear (replace if axial clearance exceeds 0.5 mm).

2. Braking System

• Replace brake pads if thickness is <5 mm; adjust brake pedal free travel.

3. Cooling System

• Clean radiator to prevent clogging and engine overheating.

V. Annual / 2,000-Hour Maintenance

Key Focus: Comprehensive overhaul

1. Engine

• Check cylinder compression and fuel injectors; replace piston rings if needed.

2. Hydraulic System

• Replace all hydraulic oil and clean the tank.

3. Structural Components

• Inspect frame welds and pivot points for fatigue cracks.

Critical Maintenance Notes

1. Grease Selection

• Use lithium-based grease (e.g., molybdenum disulfide grease) for high-temperature environments.

2. Hydraulic Oil Replacement

• Never mix different brands (may cause sedimentation).

3. Vibration Drum Bearings

• Bearing lifespan ≈3,000 hours; stop immediately if abnormal heating occurs.

4. Long-Term Storage

• Start the engine monthly to prevent seal drying.

Common Failures & Preventive Measures

Maintenance Mnemonic:

"Clean daily, inspect weekly, change oil monthly,
Overhaul quarterly, major repair yearly.
Lubricate and tighten without neglect,
Safety and efficiency stay perfect."

Following standardized maintenance can extend roller life by 30%+ and reduce breakdowns by 50%. Maintain a "Maintenance Log" to track all servicing activities.
