Competence using compression testers, pressure gauges, torque tools, micrometers and other mechanical diagnostic equipment. Ability to interpret mechanical drawings, technical manuals and manufacturer specifications. Experience supervising mechanics and inspecting completed repairs. Ability to prepare accurate job cards, parts requirements and repair reports.

Additional Requirements

• Must undergo a rigorous practical assessment using an actual heavy-duty vehicle. Must demonstrate genuine competence in both major mechanical repairs and gas-powered vehicle systems. Must understand LNG/CNG storage, gas flow, pressure regulation, injection, leak detection, shutdown and emergency-safety systems. Must observe strict gas-safety procedures and must never improvise unsafe repairs on LNG or CNG components. Must be able to distinguish between mechanical, gas-system, electrical and electronic faults. Must not recommend parts replacement without proper diagnosis. Must be safety-conscious, disciplined and accountable for repair quality. Must be willing to attend breakdowns and emergency repairs when required. Must be capable of training and supervising junior mechanics. Must be willing to work during weekends or extended hours where operationally necessary. Must not conceal defective workmanship, repeat faults or unsafe vehicle conditions.
