• Reduced system efficiency

What could be a cause of low hydraulic fluid pressure?

• High-quality fluid

• Overfilled reservoir

• Sealed hoses

• Worn-out pump

Which of these would be a part of a routine maintenance check for a hydraulic system?

• Adjusting all valves

• Checking for leaks in hoses and connections

• Inspecting seals with water

• Running the system under maximum pressure

What does excessive noise in a hydraulic system usually indicate?

• Cavitation or air in the system

• Improved performance

• Over-lubrication

• Proper functioning

How can hydraulic fluid temperature be controlled effectively?

• By adding more fluid

• By changing the pump

• By reducing system usage

• By using a cooling system
