9. The blade of the lawn mower is sluggish. The solution is to polish the blade of the lawn mower after ten days of use, and the grinding frequency of the roller blade can be extended to every three months.

10. If the lawn mower shakes or vibrates violently during operation, the solution is to grind the blades of the lawn mower to a horizontal state on both sides. During use, pay attention to the condition of the lawn and try to avoid hard objects.

The muffler of the lawn mower engine is emitting smoke. The solution is to first clean or replace the air filter with a new one. If the fault still exists, the carburetor of the lawn mower's engine needs to be cleaned and adjusted. Generally, it only needs to drain excess oil and run for ten minutes. If the fault still exists at this time, it is necessary to seek maintenance personnel to repair the engine.

14. There are two fuel supply methods. One is to use a mixture of 95% gasoline and 5% engine oil for a two-stroke lawn mower, and the other is to burn pure gasoline for a four stroke lawn mower. The four stroke lawn mower should regularly check whether the engine oil has decreased, and if it is insufficient, it should be filled with engine oil to protect the lawn mower.
