The servo filter protects the crane's control circuit — the proportional and servo valves that work with very small clearances. These valves are more sensitive to contamination than the rest of the system, so they need a finer level of filtration than the main filter provides.

Signs of a clogged servo filter are jerking when operating the controls, slower response, and imprecise positioning of the levers.

Features and application

• Finer filtration for the hydraulic control circuit
• Protects proportional and servo valves
• Prevents jerking and imprecise control operation
• Designed for cranes with proportional control
