Changing the fuel in your lawn mower primarily involves safely removing the old or stale fuel and then adding fresh fuel. This process is essential for maintaining engine health and ensuring easy starting.
Steps to Change Lawn Mower Fuel
The process of changing fuel is straightforward but requires caution when handling flammable liquids. It typically involves these key steps:
Step 1: Remove Old Fuel
Removing the existing fuel is the most critical part of changing it, especially if the fuel is old (stale) or contaminated. Always perform this step in a well-ventilated area, away from open flames or sparks, and have an approved fuel container ready.
There are a couple of common methods for safely removing fuel from the tank:
- Using a Siphon or Baster: One effective way to remove the gas is to use either a hose to siphon off the gas or a baster/pipette to remove the gas from the lawn mower gas tank to a gas can. This method is relatively simple and allows you to extract most of the fuel directly from the tank opening.
- Disconnecting the Fuel Line: Alternatively, the fuel line connecting the fuel tank to the carburetor can be disconnected at the carburetor and fuel emptied into a gas can. This method drains the fuel directly from the line and tank but may require some basic mechanical skill to locate and safely disconnect the line. Ensure the fuel line is properly reconnected afterward.
Here's a quick comparison of common fuel removal methods:
| Method | Ease of Use | Required Tools | Draining Efficiency |
|---|---|---|---|
| Siphon/Baster/Pipette | Easy | Hose, Baster/Pipette, Gas Can | Good, may leave residue |
| Disconnect Fuel Line | Moderate | Wrench/Pliers, Gas Can, Rags | Very Good |
Always dispose of old fuel responsibly according to local regulations.
Step 2: Add New Fuel
Once the old fuel has been safely and completely removed from the tank and fuel lines, you can add fresh fuel.
- Ensure the fuel cap is clean before opening the tank.
- Carefully pour the appropriate type and octane of gasoline into the fuel tank using a funnel to avoid spills. Consult your lawn mower's owner's manual for the recommended fuel type.
- Fill the tank to the recommended level, typically leaving a small amount of air space. Do not overfill.
- Securely replace the fuel cap.
With the old fuel removed and fresh fuel added, your lawn mower should be ready to start with the new fuel supply.
