1. Check the engine oil. When checking the engine oil, place the lawn mower in a horizontal position with the engine off. When the oil level is still, pull out the oil dipstick, wipe off the oil with a clean cloth, and then insert it into the oil pan to check the oil dip position of the oil dipstick. Generally, there are two scale marks on the oil dipstick. If the oil level is below the lower scale mark, add it to the upper scale. If the oil is too low, you can't use the lawn mower, or it will cause engine failure. But also do not exceed the upper scale, too much oil will cause power decline and smoke. It is worth noting that if the oil dipstick has a screw thread, it is only necessary to insert the oil dipstick when checking the oil position.

 

2. Check the oil level in the oil tank. Lawn mowers generally use four range engines. Therefore, pure gasoline must be used instead of mixed oil of engine oil and gasoline. Avoid dirt, dust and water in the oil tank when refueling.

 

Gasoline is inflammable and explosive. Refueling must be carried out in a well ventilated place with the engine stopped.

 

② do not smoke at the fuel filling place or fuel storage place of lawn mower, and do not work in the area easy to cause sparks.

 

(3) be careful not to spill gasoline outside when refueling. Gasoline volatile gas or spilled gasoline is easy to catch fire. Before starting the engine, make sure that the spilled gasoline is evaporated.

 

(4) do not let the gasoline in the oil tank overflow. After filling, be sure to tighten the oil cap.
