🔍 Key Concepts

• Stored energy in hydraulic accumulators and why it is dangerous when working on the system • Function of component E in the illustration and what kind of device it is • Proper safety procedure before disconnecting or removing any control valve in a pressurized hydraulic system

💭 Think About

• Look at line connections leading into and out of the starter control valve (F). Which component in the system could still hold high pressure even after the pump is secured? • If you simply drained the reservoir (A), would that automatically remove pressure from all parts of the system, especially from E? Why or why not? • Consider what would happen to the mechanic standing at F if E is still fully charged when a line or fitting is loosened.

✅ Before You Answer

• Identify component E and confirm whether it is able to store pressure even with the pump stopped • Verify which action directly ensures no trapped pressure remains at F before removal • Eliminate any options that deal only with fluid level (like the reservoir) or that would actually make the system less controlled or more hazardous during maintenance
