3. Installation Instructions
This section outlines the steps for replacing your existing fuel cap with the Mountfield Original Stiga Fuel Cap. Ensure the engine is cool and turned off before proceeding.
- Prepare the Lawnmower: Ensure the lawnmower engine is completely cool and switched off. Disconnect the spark plug wire to prevent accidental starting.
- Locate the Fuel Tank: Identify the fuel tank on your Stiga lawnmower. The fuel cap is typically located on top of the fuel tank.
- Remove the Old Fuel Cap: Turn the old fuel cap counter-clockwise until it loosens and can be removed. Exercise caution to avoid spilling any fuel.
- Inspect the Fuel Tank Opening: Check the fuel tank opening for any debris or damage. Clean if necessary.
- Install the New Fuel Cap: Place the new Mountfield Original Stiga Fuel Cap onto the fuel tank opening. Turn it clockwise until it is securely tightened. Do not overtighten.
- Verify Seal: Ensure the cap is seated properly and forms a tight seal to prevent fuel leakage and evaporation.

4. Operating Instructions
The fuel cap's primary function is to seal the fuel tank. Proper operation involves ensuring it is securely fastened before and during lawnmower use.
- Always ensure the fuel cap is tightly closed before starting or operating the lawnmower.
- When refueling, remove the cap slowly to release any pressure buildup.
- After refueling, replace the cap and turn it clockwise until it clicks or feels secure.
5. Maintenance
Regular inspection and simple maintenance can extend the life of your fuel cap and ensure safe operation.
- Regular Inspection: Periodically check the fuel cap for cracks, damage, or signs of wear on the threads or sealing gasket.
- Cleaning: If the cap becomes dirty, wipe it with a clean, damp cloth. Avoid using harsh chemicals that could damage the plastic.
- Gasket Check: Ensure the internal gasket (if present) is intact and pliable to maintain a proper seal. A damaged gasket can lead to fuel leaks or evaporation.
- Replacement: If the fuel cap shows significant wear, damage, or no longer seals effectively, replace it immediately with a genuine Mountfield Original Stiga part.
