• Lead teardown, failure analysis, overhaul and complex repairs of hydraulic pumps, motors, cylinders, valves, manifolds, accumulators and hydraulic power units.
• Perform precise testing, calibration and commissioning of hydraulic systems using advanced diagnostic equipment including hydraulic flow meters, pressure transducers, contamination monitors, particle counters and electronic diagnostic tools.
• Perform diagnostics, fault finding and repairs on hydraulic cylinders, pumps, valves, motors, hoses, manifolds and electro-hydraulic systems. Support installation and removal of hydraulic components on equipment or machinery.
• Troubleshoot high-pressure, load-sensing, pilot-operated, proportional and electro-hydraulic systems across a wide range of mobile and fixed equipment.
• Supervise or carry out installation and commissioning of new hydraulic systems or major hydraulic modifications.
• Respond to customer breakdowns and perform mobile repairs and maintenance on-site as required.
• Carry out Root Cause Failure Analysis (RCFA) on hydraulic component failures and recommend permanent corrective actions.
• Read and interpret complex hydraulic and electrical schematics for fault diagnosis and repair.
• Manufacture, install and pressure test hydraulic hose assemblies where required.
• Maintain hydraulic cleanliness standards and contamination control practices in accordance with OEM recommendations.
• Ensure all repairs are completed in accordance with manufacturer specifications and company quality standards.
• Follow all workplace safety procedures including proper PPE use, hydraulic isolation procedures, Lock Out Tag Out (LOTO) and hydraulic safety practices.
• Ensure safe working practices are carried out at all times in accordance with Health and Safety legislation and company policies.
• Maintain detailed records of maintenance activities, repairs, inspections, commissioning reports and hydraulic testing results.
• Mentor, coach and train Level 1 and Level 2 Hydraulics Technicians, ensuring safe working practices and continual skills development.
• Support the Hydraulic Foreman with workload planning, technical guidance and continuous improvement initiatives.
