Core Responsibilities

Primary Functions

Perform comprehensive diagnostic tests on complex hydraulic and pneumatic systems using pressure gauges, flow meters, and other specialized diagnostic tools to accurately identify malfunctions, leaks, and performance deviations.
Execute the complete overhaul and rebuilding of critical hydraulic components, including pumps (piston, vane, gear), motors, servo valves, and cylinders, ensuring they are restored to OEM specifications and performance standards.
Read, interpret, and analyze intricate hydraulic and pneumatic schematics, blueprints, and technical service manuals to guide systematic troubleshooting and complex repair procedures.
Conduct precision installation, commissioning, and testing of new or refurbished hydraulic systems and machinery, ensuring proper alignment, fluid purity, and operational safety before handover.
Perform preventive and predictive maintenance tasks on a wide range of industrial and mobile equipment, including fluid analysis, filter replacement, and system flushing, to minimize unplanned downtime.
Troubleshoot and repair hydraulic hose and tube assemblies, which includes proper selection, cutting, fitting, and crimping to withstand system pressures and environmental conditions.
Skillfully dismantle and inspect hydraulic components for wear, fatigue, and damage, utilizing precision measuring instruments like calipers, micrometers, and bore gauges to determine serviceability.
Set up and operate hydraulic test stands to bench-test repaired components, verifying their performance, efficiency, and leak-free operation under simulated working conditions.
Adjust and calibrate system components, such as pressure relief valves, flow control valves, and proportional valves, to fine-tune machine performance and ensure operational safety.
Respond to emergency breakdowns, applying rapid and effective troubleshooting techniques to diagnose the root cause of hydraulic failures and implement immediate corrective actions.
Fabricate and/or modify brackets, mounts, and simple mechanical parts using welding, cutting, and grinding equipment to support hydraulic system installations and repairs.
Ensure all hydraulic fluids are handled, stored, and disposed of in accordance with environmental regulations and safety protocols to prevent contamination and spills.
Isolate and lock-out/tag-out machinery safely before commencing any maintenance or repair work, strictly adhering to all company and OSHA safety procedures.
Document all work performed, parts used, and system test results in a Computerized Maintenance Management System (CMMS) with a high level of detail and accuracy.
Evaluate and diagnose issues with the electrical control interfaces of hydraulic systems, including solenoids, sensors, and basic PLC logic, to resolve electro-hydraulic faults.

Secondary Functions

Maintain a clean, organized, and safe work environment, including the workshop, service vehicle, and job sites, to promote efficiency and prevent accidents.
Manage and control the inventory of hydraulic spare parts, fittings, seals, and fluids, communicating with an MRO buyer to place orders and ensure critical parts are on hand.
Provide technical support and guidance to machine operators and junior maintenance personnel on the proper operation and basic care of hydraulic systems.
Collaborate with engineering and reliability teams to provide feedback on equipment performance and suggest modifications or upgrades to enhance system reliability and efficiency.
Participate in root cause analysis (RCA) meetings for significant equipment failures, contributing your technical expertise to help develop lasting solutions.
Stay current with the latest advancements in hydraulic technology, components, and diagnostic techniques through continuous training and self-study.
