Core Responsibilities

Primary Functions

Conduct in-depth troubleshooting and root cause analysis on malfunctioning hydraulic systems, including pumps, motors, cylinders, valves, and actuators, to identify and resolve operational failures.
Execute comprehensive preventative and predictive maintenance schedules on all hydraulic equipment to minimize downtime and extend asset lifespan.
Interpret complex hydraulic schematics, blueprints, and technical manuals to guide installation, repair, and diagnostic activities.
Skillfully disassemble, inspect, repair, and rebuild major hydraulic components, ensuring all parts meet or exceed manufacturer specifications.
Assemble and install new hydraulic systems and components, ensuring proper alignment, connection, and integration with existing machinery.
Perform precise pressure and flow testing on hydraulic systems using specialized diagnostic equipment to verify performance and ensure safe operating parameters.
Fabricate, install, and properly route hydraulic hoses and steel tubing, paying close attention to pressure ratings, bend radii, and abrasion points.
Maintain meticulous and accurate documentation of all maintenance activities, service reports, parts usage, and system modifications in a CMMS (Computerized Maintenance Management System).
Operate and maintain a variety of diagnostic tools, including pressure gauges, flow meters, temperature sensors, and data loggers.
Perform necessary welding and fabrication tasks to create or repair mounts, brackets, and other structural components related to hydraulic systems.
Manage fluid cleanliness by performing oil analysis, filtration, and fluid replacement procedures to prevent contamination-related failures.
Adhere rigorously to all company and industry safety protocols, including Lock-Out/Tag-Out (LOTO) procedures, before beginning any maintenance or repair work.
Collaborate with the parts department to accurately identify, specify, and order required hydraulic components, parts, and supplies.
Apply expertise to both stationary industrial machinery (e.g., presses, injection molders) and mobile heavy equipment (e.g., excavators, cranes).
Provide clear and concise technical support and guidance to machine operators and other maintenance personnel regarding the proper operation and care of hydraulic systems.
Calibrate hydraulic system controls, including pressure relief valves, flow control valves, and proportional valves, to achieve precise operational outcomes.
Respond to emergency breakdown calls in a timely and effective manner to restore equipment to service as quickly and safely as possible.
Conduct thorough post-repair inspections and operational tests to ensure the initial problem has been fully resolved and the equipment is safe for return to service.
Utilize precision measuring instruments like calipers, micrometers, and bore gauges to assess component wear and determine refurbishment needs.
Install and troubleshoot electro-hydraulic systems, including proportional and servo valves, requiring a basic understanding of electrical control signals and PLC interfaces.

Secondary Functions

Provide hands-on mentorship and technical guidance to junior technicians and apprentices on complex hydraulic diagnostics and repair techniques.
Actively contribute to the continuous improvement of maintenance procedures and safety protocols by suggesting data-driven enhancements.
Collaborate with engineering and operations departments to provide practical input on potential system upgrades, modifications, or replacements for improved reliability and efficiency.
Participate actively in departmental team meetings, daily safety briefings, and ongoing professional development training to stay current with industry best practices and new technologies.
