A. Functional Features 1. It can be used to replenish the hydraulic oil of the ship's steering system. The transparent hose helps with observing the oil flow, making the exhaust and oil - filling processes relatively easier and more efficient. 2. It is applicable to Seastar in - boat and out - boat hydraulic steering systems and can be used to refill the hydraulic oil of the boat's steering system. 3. The brass pipe fittings and PVC pipes have good mechanical and physical properties, with certain oxidation resistance, corrosion resistance and durability. 4. It can help keep the entire steering system sealed throughout the exhaust process. 5. One bridge tube is screwed onto the fuel tank, and the other bridge tube is connected to the exhaust connector. B. Product Specifications 1. Material: Polyurethane, stainless steel 2. Colors: Gold, black, transparent 3. Length of the black tube: Approximately 46 cm/18.11 inches 4. Length of the yellow tube: Approximately 45 cm/17.72 inches 5. Product dimensions: 20×14×14 cm 6. Package weight: 150 grams C. Usage Steps 1. Connect the oil bottle to the steering gear reservoir (do not pierce the oil bottle) (avoid letting the oil bottle empty). 2. Connect the bridge tube to the connector of the steering cylinder and loosen the connector. 3. By turning the steering wheel in one direction, use the steering gear to pump the hydraulic oil through the system. Bubbles will be pushed into the reservoir at the steering gear. 4. Manually swing the outboard motor through a full angle to release the trapped air. 5. Note: When using the steering gear to pump hydraulic oil, place the connector upwards to allow air to escape from the cylinder. 6. If needed, repeat steps 3 - 4 until no air is visible in the bridge tube. 7. Tighten the connector before removing the bridge tube. D. Package List 1. One bridge tube 2.
