at incorrect pressure settings -Correct Answer-air compressor
controls
many modern pneumatic systems use clear or semiclear____
without reinforcement layers or cords -Correct Answer-tubing
____ is the practice of periodically inspecting and repairing
equipment -Correct Answer-maintenance
the advantage of a ______ program is that is reduces the amount
of troubleshooting that may need to be performed -Correct
Answer-routine maintenance
