Steps for Diagnosis:

1. Isolate and identify the specific problem or symptom.
   2. Using the table below, match the symptom with the corresponding probable causes and suggested corrective actions.
   3. Execute the remedies as they are listed in order.
   4. Perform checks as suggested or refer to the relevant section of the manual.
   5. If needed, repair or replace the faulty section of the scales.

NOTE:
