🔌 Function

Routes hydraulic fluid between the pump/manifold and trim cylinders, providing the paired pressure paths needed to extend and retract the rams.

Common signs of failure or replacement requirement:

• Fluid leakage at crimps or fittings

• Cracked or abraded hose outer covering

• Uneven cylinder movement from pressure loss

• Air entering the circuit and causing jerky operation

• Drive drifts down or cannot reach full tilt
