Detailed Inspection Procedures
Follow these structured procedures to ensure a thorough inspection of your paving equipment. Adapt these steps to your specific machine model and operating conditions.
Screed Heating System Check
- Ensure all heating controls are in OFF position
- Inspect heating elements for damage and proper connections
- Start engine and allow to reach operating temperature
- Activate heat and verify indicator lights function
- Check each zone individually for proper heating
- Verify temperature sensors are providing accurate readings
- Allow system to reach operating temperature
- Use thermal imaging if available to check for cold spots
Material Feed System Inspection
- Check conveyor belt/slat condition and tension
- Ensure all flights and slats are present and secure
- Verify conveyor chain tension (1-2" deflection)
- Inspect floor plates for excessive wear or damage
- Check auger condition, bearings, and drive system
- Verify auger height adjustment mechanism function
- Test feed sensors with engine running
- Operate system manually to verify smooth operation
Grade Control System Check
- Clean all grade and slope sensors thoroughly
- Inspect sensor mounts and fasteners for security
- Check all cables and connections for damage
- Power up system and verify display functionality
- Perform nulling/calibration procedure per manual
- Verify sensor responds to manual movement
- Check operation in both auto and manual modes
- Verify system holds grade consistently
Hydraulic System Inspection
- Check hydraulic oil level with all cylinders retracted
- Inspect hydraulic tank, cap and breather for cleanliness
- Examine all visible hydraulic hoses for wear or leaks
- Check cylinder rods for scoring or damage
- Verify hydraulic filter indicators are in normal range
- Start engine and test all hydraulic functions
- Listen for unusual noises from pumps or motors
- Check hydraulic oil temperature during operation
