Step-by-Step Guide to Draining Gas from Your Lawn Mower
1. Cool Down Your Mower: Allow the engine to cool completely before attempting to drain the gas.
2. Locate the Fuel Shut-Off Valve: The fuel shut-off valve is typically located on the fuel line, near the gas tank or carburetor. It may be a lever or a knob.
3. Turn Off the Fuel Shut-Off Valve: Close the valve completely to prevent any more fuel from flowing to the engine.
4. Disconnect the Fuel Line: There are two ways to approach this depending on your mower:
**a. Quick Disconnect:** If your mower has a quick disconnect on the fuel line, simply push the release button and pull the line apart.
**b. Manual Disconnect:** If you have a manual connection, gently pry the line loose from the carburetor or tank using a screwdriver or pliers.
5. Drain the Gas: Hold the fuel line over your container and allow the gas to drain out. If your mower doesn’t have a drain valve, you can tilt the mower slightly to encourage the fuel to flow out.
6. Re-connect the Fuel Line: Once the tank is drained, re-connect the fuel line securely. Be sure to properly align the quick connect or tighten the manual connection.
7. Clean Up: Wipe up any spills with a rag or paper towels. Dispose of the used gasoline properly according to your local regulations.
Tips for a Smoother Drain
- Using a Siphon: For larger amounts of fuel, using a siphon can make the draining process quicker and easier. You can purchase a siphon specifically designed for gasoline at most hardware stores.
- Fuel Tank Drain Valve: Some newer lawnmowers have a dedicated fuel tank drain valve, which simplifies the process. Check your owner’s manual for instructions on how to use this feature.
Preventative Maintenance:
- Fuel Stabilizer: Adding fuel stabilizer to your gasoline can extend its shelf life and prevent problems. Follow the instructions on the stabilizer product for proper usage.
- Seasonal Storage: When storing your lawnmower for the off-season, drain the gas tank and run the engine until it stops, using any remaining fuel. This will prevent the fuel from gumming up the fuel system.
When to Call a Professional
If you’re uncomfortable draining the fuel yourself or if your mower has any unusual problems, it’s best to consult a professional mechanic. They can diagnose any underlying issues and provide safe and efficient maintenance for your lawnmower.
Conclusion
Draining your lawn mower’s gas tank is a straightforward process that can save you a lot of headaches in the long run.
