When the engine fails to start, it is always important to check the fuel status before embarking on other advanced lawn mower repair processes. When dealing with a 4-cycle machine, it is ideal to ascertain that the oil used is the recommended type, it is clean and it is adequate to run the machine. On the other hand, the 2-cycle machines require a mixture of the recommended type of oil and gasoline well shaken to create a perfect blend. The integral step in the lawn mower repair is to guarantee the safety of the engine, individuals and property.

To ensure the machine safety, it is important to avoid recycling old oil. To ensure the safety of others and equipment, keep the engine oil in a cool and dry place away from hazards such as sparks and flames. It is also essential to avoid keeping the oil over the winter period as the bad oil can affect the engine negatively.
