How to use a lawn mower correctly?

When using a lawn mower, the first thing to do is to ensure the safety of the power line. Do not leave the wires within the mowing range to prevent the lawn mower from cutting them off. Secondly, when using the lawn mower, do not let it rise from the ground height to avoid sudden throwing of the lawn mower and injury to personnel. Finally, when the lawn mower is in operation, attention should be paid to touching the bottom of the lawn mower to avoid hand injuries.
