Using the principle of Pascal's Law, the learner will interpret the gauge readings in a hydraulic system to determine when the system is operating properly under various load conditions and when there is a defect.

Studies show that more than 75 percent of all hydraulic system failures are a direct result of unclean oil. In this interactive object, learners examine the three primary types of hydraulic system filters. A brief quiz completes the activity.

This animated lesson demonstrates hydraulic pressure switch applications when the switch is connected to a ladder circuit to operate in a hydraulic system.

This animated lesson shows several ways that a hydraulic pressure switch, connected in a ladder circuit, causes the cylinder of a hydraulic circuit to perform various applications.

Step-by-step of setting the back gauge with an Adira Hydraulic Shear.

In this interactive object, learners set up a shear, enter the back gauge dimension, and prepare to shear metal in a simulation of the Adira Hydraulic Shear.

In this animated object, learners examine how various types of positive and non-positive displacement hydraulic pumps work.

In this learning activity you'll review safety considerations for using hydraulic press brakes.

In this interactive object, learners examine how work is performed in foot-pounds by a hydraulic system that uses a pump and cylinder. A brief quiz completes the activity.

Learners read about the similarities of electronic and hydraulic components and then match the schematic symbols in a drag-and-drop exercise.

In this animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.

In this animated and interactive object, learners use a color code to understand the operations of a hydraulic circuit. A brief quiz completes the activity.

In this screencast, learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.

Learners observe the four functions of oil in a hydraulic system.

This interactive learning object is designed to help learners memorize the color code used on some hydraulic schematic diagrams. Learners quiz themselves using electronic flashcards.

Learners follow an animated test procedure to determine if the parts of a hydraulic pump are worn.

In this animated activity, learners examine the operation of hydraulic directional control valves and the internal components that divert the fluid.

In this learning activity you'll review safety considerations for persons using a hydraulic iron worker and takes a short quiz.

The operation of a hydraulic brake valve, including the internal components, is presented using animations.
