Facilitated 6 week online fluid power program.

Language Session

Prerequisite: Participants must have access to The Lubrication Engineers Manual, 2nd Edition

Sweating the CLS™ exam?
Lubrizol K2M in cooperation with the STLE™ has developed a series of seven online programs to help you.

The Fluid Power Program is a 6 week program designed to reinforce your knowledge of the operation of hydraulic systems, the difference in hydraulic pumps and the use of fluids; their power, condition and compatibility. This program will also discuss hydraulic pump failure; a variety of causes and how to prevent such failures. It will also cover how to interpret a fluid analysis report and the significance of abnormal readings.
