Solving some common problems in lawn mowers immediately endangers the lifespan of the mower.

1£º How to clean the air filter of a lawn mower?

The foam plastic filter element shall be cleaned every 25 hours, and the dust shall be more frequent.

The foamed plastic filter element shall be cleaned with gasoline or detergent and cold water. It shall be extruded and dried. Then it shall be soaked with automobile oil, and unnecessary automobile oil can be squeezed out before installation. If it says' DONNOTOIL ', there is no need to add oil.

Clean the paper filter cartridge every 25 hours, and more frequently when there is heavy dust.

The front filter device containing the front air filter is cleaned every 25 hours, and the paper core is cleaned every 100 hours. When there is a lot of dust, it should be done more frequently.

The cleaning of the front air filter is the same as that of the foam plastic filter element.

The paper filter element should be tapped on the plan. If it is very dirty, a should be replaced or cleaned in low or no foam plastic detergent and warm solution; B Clean thoroughly with water flow from the inside to the outside until the water flow stops cleaning; Place it upright and blow dry.

Attention: Do not use crude oil organic solvents, such as gasoline, to clean paper cores. As it is highly likely to cause mold on the paper core, it is not necessary to put car oil on the paper core, and air compression should not be used to clean or dry the paper core.

2£º Why do lawn mowers use a large accelerator pedal when weeding?

The rotary blade lawn mower uses the high-speed operation of the blade to cut grass. If the angular speed of the sharp blade is insufficient, the actual effect of grass cutting is not very good. Therefore, when cutting grass, use a large accelerator pedal to rotate at high speed. In addition, the carburetor and fully automatic transmission equipment of the lawn mower ensure that its fuel consumption is not high when the large throttle pedal is unloaded. Only when it is loaded, its speed ratio will increase from 3400r. p.m. to 2800r. p.m. at full load. Therefore, there is no need to use a small throttle pedal to save fuel, and the actual effect of grass cutting is not very good.

3£º Why should car oil be removed and replaced on time?

The appropriate model of car oil for lawn mowers has the following effects on the equipment: wetting, reducing temperature, cleaning, and improving piston rod sealing. After a period of application, various characteristics of the equipment will be reduced, accompanied by the entry of smoke and dust in the air and the entry of metal material scraps from equipment damage into car oil and car oil when exposed to heat, and fitness activities. If the oil is not replaced immediately, it may accelerate equipment damage, reduce the service life of the equipment, and even lead to safety accidents such as bearing pads, engine cylinder pulling, and crankshaft rupture. Therefore, the oil should be replaced within a specified time limit according to the instructions for use, to ensure all normal applications of the equipment.

5£º Why do we need to clean and replace the lawn mower air filter on time?

The air filter element is used to prevent dust from entering the engine cylinder block and prevent early damage to equipment parts caused by dust entering the engine cylinder block. It should be cleaned frequently and replaced within a specified period of time. During the application of the equipment, the dust and dust extracted from the pump will accumulate on the air filter element, reducing the intake volume and increasing the ignition mixing ratio, resulting in incomplete ignition and reduced output power. Long term summarization can cause carbon deposition, exacerbating damage between the cylinder and piston, and carbon deposition falling on the engine cylinder block
