Construction Machinery Common Knowledge

1. Hydraulic System Maintenance: Regularly check hydraulic fluid levels and inspect for leaks to prevent system failures in excavators and loaders.

2. Undercarriage Inspection: For bulldozers and excavators, daily inspection of rollers, idlers, and track shoes can extend the life of undercarriage components.

3. Engine Care: Ensure timely oil changes and air filter replacements in graders and other machinery to maintain engine efficiency and prevent breakdowns.
