Having a dirty spark plug may result in your lawn mower running poorly or the product can be damaged.
To decrease the risk of unwanted material on the spark plug electrodes, follow the instructions:
⚠️CAUTION: Always use the recommended spark plug type. Incorrect spark plug type can cause damage to the product.
Examine the spark plug if the engine is low on power, is not easy to start or does not operate correctly at idle speed.
To decrease the risk of unwanted material on the spark plug electrodes, make sure that the fuel mixture is correct and that the air filter is clean.
If the spark plug is dirty, clean it and make sure that the electrode gap is correct, refer to your product manual.
Replace the spark plug if it is necessary.
