Hydraulic Fluid Power
Fluid Control
Course Number: HFP-303
Course Description:
This industrial hydraulics course is designed to enhance the ability of the Mechanical Maintenance worker to accurately troubleshoot and repair Hydraulic System problems. This goal is achieved through teaching the participants what each component of a system does and how to troubleshooting these components in a system. Also, to aid in the understanding of the sequence of operation of a system, student are shown how to read Hydraulic schematics allowing them to narrow down the problem area to a unique set of or even one single component as the most likely cause. Our training stands offer an opportunity to build simple and more complex hydraulic circuits as well as plenty of opportunities to troubleshoot problems and get the system working again. A fantastic opportunity to learn hydraulics in just three days.
​
Each student will receive class books, work activity sheets, self-test progress evaluations, as well as questions from the instructor to make sure they understand the material presented. It is expected that an attendee will leave the class with the basic knowledge of the subject and possess new found skills to better equip them when they return to their job. A certificate suitable for framing will be issued to each attendee who successfully completes the course.
