This unit involves the skills and knowledge required to provide solutions to pneumatic-hydraulic system operations.

It includes identifying, providing, completing and documenting solutions to discovered problems in pneumatic-hydraulic system operations. It also includes setting up and maintaining pneumatic and hydraulic systems; applying problem-solving procedures, including using measuring instruments; applying appropriate circuit theorems; and providing solutions derived from measurements and calculations and justification for such solutions.

No licensing, legislative or certification requirements apply to this unit at the time of publication.
