1. Product Overview
This manual hand siphon pump is designed for quick, spill-free transfer of liquids. It features a squeeze bulb for easy priming, flexible hoses for hard-to-reach access, and is ideal for automotive, marine, and household fluid transfer tasks. This product is made of chemical-resistant plastic, suitable for most automotive fluids, water, and non-corrosive chemicals.

2. Safety Information
WARNING: Failure to follow these safety guidelines may result in injury or property damage.
- Flammable Liquid Safety: When transferring flammable fluids (e.g., gasoline, diesel), use only in a well-ventilated area away from open flames, heat sources, or sparks to avoid fire or explosion hazards.
- Chemical Compatibility: Do not use with highly corrosive, toxic, or high-temperature liquids above 60°C (140°F) to prevent material degradation, leakage, or injury.
- Food Contact Prohibition: This product is not certified for food or drinking water transfer. Do not use for edible liquids.
- Keep Away from Children: Store the siphon out of reach of children to prevent accidental ingestion, choking, or misuse.
- Pressure Safety: Do not over-squeeze the bulb or block the outlet, as this may cause hose rupture or liquid backflow.
3. Setup
- Prepare the Siphon: Inspect the pump and hoses for cracks, tears, or blockages before use. Ensure all connections are tight and secure.
- Position the Hoses: Insert the longer rigid intake hose fully into the source liquid container. Place the flexible outlet hose into the receiving container, ensuring the outlet is lower than the source liquid level.

4. Operating Instructions
- Prime the Siphon: Squeeze the red bulb repeatedly to expel air and draw liquid into the hose. Once liquid flows continuously through the outlet, stop squeezing and let gravity complete the transfer.
- Stop Transfer: To stop flow, lift the outlet hose above the source liquid level, or pinch the hose to block flow. Then remove the intake hose from the source container.

5. Maintenance
- Clean After Use: Flush the siphon thoroughly with clean water after use, especially after transferring chemicals or fuels. Dry completely before storage. For fuel transfer, use a fuel system cleaner, then air dry completely before storage.
- Avoid Kinking: Do not sharply bend or kink the flexible hose, as this will block flow and damage the hose structure.
- Regular Inspection: Check the bulb, hoses, and connections for wear, cracks, or leaks before each use. Replace damaged parts immediately.
- Storage Requirements: Store in a cool, dry place away from direct sunlight and extreme temperatures to prevent material aging and brittleness.
- Do Not Modify: Do not alter the pump structure or use it for purposes other than liquid transfer, as this will void the warranty and create safety risks.
6. Troubleshooting
Q: Why won't the siphon start?
A: Ensure the outlet hose is lower than the source liquid level, the intake hose is fully submerged, and there are no kinks or blockages in the hoses. Squeeze the bulb firmly to expel all air from the system.

9. User Tips
- This pump is particularly useful for reaching awkwardly placed reservoirs, such as windshield washer fluid tanks.
- While effective, the transfer speed might be slow for larger volumes, so plan accordingly for tasks like refueling a generator.
- The product is generally suitable for occasional, light-duty fluid transfers, such as extracting oil from a lawnmower once a year. For frequent or heavy-duty use, consider alternative options.
- Be mindful of the flexible hose; some users have noted it can bend easily. Handle with care to prevent kinks that could impede flow.
