How is the hydraulic system powered off?

• A. Electrically
• B. Pneumatically
• C. Hydraulically
• D. Mechanically

Answer: (A)

Hydraulics rely on a pump driven by an energy source, most commonly an electric motor. To power the hydraulic system off, you disrupt that energy supply by cutting electrical power to the pump. Once the motor loses power, the pump stops, pressure drops, and the system shuts down. This is why the method of turning off electrical power is the standard answer. Using air (pneumatic), the hydraulic-medium itself (hydraulic), or a manual/mechanical action would not universally represent how the system is turned off in typical setups.
