Confirm that the battery is secure and terminal connections are clean and tight, and inspect belts and pulleys for proper tension and wear. Record any anomalies and ensure the machine is on level ground with the tracks or wheels properly seated before proceeding to functional testing. Functional testing procedures Engage the engine at a low idle and perform a controlled ramp to operating speed while monitoring oil pressure, temperature, and electrical system indicators. Observe for abnormal noises, vibrations, or smoke, and verify that all gauges respond within expected ranges as rpm increases. With the machine in a safe operational posture, test primary hydraulic functions such as boom lift, lower, and extension if applicable, noting response times and relief valve settings. Execute a series of controlled movements to assess drive motors or hydraulic motors for smooth operation and consistent speed changes without surging. Validate auxiliary systems including the cooling fan, charging system, lighting, and instrument panel warnings; address any fault codes or abnormal readings with the diagnostic procedures outlined in the service manual. Calibrate fuel and air systems if necessary by following the specified procedure, ensuring proper idle characteristics and stable acceleration without misfires. Perform a functional test of the safety interlocks, seat switch, and operator presence verification to confirm that all safety features engage appropriately during operation. Final performance verification After completing functional testing, conduct a comprehensive performance check that replicates typical field conditions such as loading, travel over varied terrain, and precise control of hydraulic outputs. Compare real-world performance against factory specifications for speed, lift capacity, hydraulic flow, and cycle times; document any deviations and determine if they stem from calibration drift, wear, or component degradation. Re-check all critical systems under load, including hydraulic temperatures, engine temperatures, and transmission or drive-system temperatures, ensuring they remain within acceptable limits. Perform a test run on a closed loop or test area to confirm predictable operation, including braking effectiveness, steering precision, and stability on uneven surfaces. Conclude with a final diagnostic scan to capture any residual fault codes and verify that repairs or adjustments have resolved prior issues. Ensure all safety guards are reinstalled and the machine is secured with appropriate lockout or tagout procedures if another personnel will be performing maintenance. Document the entire testing and calibration sequence with timestamps, readings, and the names of personnel involved for traceability and future reference.The MASSEY FERGUSON 2920LC service manual section titled Appendices and reference data consolidates essential data that technicians rely on for precise maintenance and repair work.
