Every time you use the lawn mower, check the oil level to see if it is between the upper and lower scales of the oil scale. 5 hours after the use of new machines should be replaced with oil, the use of 10 hours after the oil should be replaced once again, according to the requirements of the manual after the regular replacement of oil. Replace the oil should be in the engine in a heat state. Filling the oil can not be too much, otherwise it will appear: black smoke, lack of power (cylinder coke too much, spark plug gap small). Engine overheating and so on. Filling the oil can not be too little, otherwise it will be: the engine gear noise, piston ring to accelerate wear and damage. Even the current tile and other phenomena, causing serious damage to the engine.
