Purpose of Seminar:
In the course, you’ll learn to focus on the troubleshooting process and the inspection
and testing tasks that are part of a systematic approach to locating malfunctions and
their underlying causes. Students will become aware of decision-making processes, which
is the first important step to a solid troubleshooting procedure. And several hands-on
lab demonstrations will allow the students to troubleshoot real world system problems.
Every application discussed will be totally dissected in a state-of-the-art animated
program so that the students can see what happens when they recalibrate pressure, flow,
torque, load or even upsize and downsize components.
No longer will you need to guess or try to fix problems by merely substituting parts.
When it comes time to fix something after attending this seminar, you’ll know exactly
what to do, why you are doing it and be confident that it works!
What You Will Learn
- Create and match a variety of hydraulic applications to the work to be performed
- Properly test and inspect hydraulic systems
- Diagnose system versus component problems
- Distinguish problem “symptoms” from the actual “cause”
- Apply a common-sense, systematic approach to troubleshooting
- Evaluate the cause and effect of changing or re-sizing system components
- Recommend and implement change towards fixing problems
Who should take this course?
This course is designed for anyone who needs to understand hydraulic components and
systems for work in industrial and mobile equipment applications.
