a The real force produced by a cylinder will be less than the theoretical output because of internal friction and external side loading.
a Flow control valves are studied in Exercise Exercise 3.

Identifying the actuators
a You will study flow control valves and directional control valves in Exercise Exercise 3.
a Following each of these tables is a figure showing the actuators in the workstation. In Step 9, you will use these figures to identify the actuators.

a Tighten the lock nuts on the flow control valves hand tight. Do not over tighten them as your instructor may adjust them before you restart the system.
Since this step is intended to remind you that all actuators need to be firmly mounted and regularly inspected, it is not necessary to use a tool to verify that the actuator hardware is properly tightened. A visual inspection is sufficient.

Troubleshooting
a As a systems operator, you should be able to localize malfunctions and identify their causes and sources. In some cases, you will be able to fix the malfunction yourself. In many cases, however, you will be required to document the malfunctions and pass this information onto the appropriate experts for resolution. Be as precise as possible in describing the problem. Refer to all components using the correct names and device tags as shown in the system plans.
