INTRODUCTION

In industry, troubleshooting skills often matter more than building a circuit in the first place—because machines rarely break when it’s convenient. Pneumatic systems drive countless production processes, and downtime costs companies money every minute. You’ve already learned how reciprocating circuits work and practiced assembling one. In this assignment, your circuit will be altered, and you will practice diagnosing and repairing it to restore proper function.
