Steps to Change the Spark Plug
- Ensure Safety: Make sure the engine is cool to prevent burns. Turn off the ignition and remove the key.
- Locate the Spark Plug: The spark plug is located on the right side of the engine. Remove the spark plug cap by pulling it off gently.
- Remove the Old Spark Plug: Use the spark plug socket wrench to unscrew the old spark plug. Turn counterclockwise until it is loose enough to remove by hand.
- Check the New Spark Plug: Before installing, check the gap on the new spark plug using a gap tool. The correct gap for the PW80 is 0.6-0.7mm. Adjust if necessary.
- Install the New Spark Plug: Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the socket wrench to snug it up. Do not over-tighten.
- Reattach the Spark Plug Cap: Push the spark plug cap back onto the new spark plug until it clicks into place.
- Test the Engine: Start the engine to ensure it runs smoothly. If it doesn't start or runs poorly, recheck the spark plug installation.
