• Preventative Maintenance: Conduct routine inspections and perform scheduled preventative maintenance (PM) on machinery to prevent failures before they occur. Maintain accurate maintenance logs and service records.
• Troubleshooting and Repair: Diagnose and repair mechanical, electrical, hydraulic, and pneumatic systems issues.
• Installation and Calibration: Assist with the installation, relocation, leveling, and alignment of new and existing machinery. Perform calibrations to ensure machines operate to exact specifications and tolerances.
• Documentation and Inventory: Read and interpret technical manuals, electrical schematics, blueprints, and wiring diagrams. Monitor and maintain spare parts inventory, placing orders as needed.
• Safety and Compliance: Adhere to all safety procedures and regulations, including Lockout/Tagout, personal protective equipment (PPE) protocols, and electrical safety standards.
• Collaboration: Work closely with the production and engineering teams to prioritize repairs, improve processes, and provide technical support or training to machine operators as needed.
• General Facility Maintenance: Perform general building and grounds maintenance as required.
• Supporting lean manufacturing projects as needed.
