Petrol Lawn Mower Manufacturers Introduce Common Faults And Maintenance Methods Of Lawn Mowers

Petrol Lawn Mower Manufacturers introduce common faults and maintenance methods of lawn mowers:

1. Reasons for the engine not running smoothly:
The throttle is at maximum position, the damper is open; the spark plug wire is loose; water and dirt have entered the fuel system; the air filter is too dirty; the carburetor is not adjusted properly; the engine fixing screws are loose: the engine crankshaft is bent. Remedy: lower the throttle switch: press the outer wire of the spark plug firmly; clean the fuel tank and refill the clean fuel; clean the air filter or replace the filter element; readjust the carburetor; check the engine fixing screw after turning off the engine: correct the crankshaft or replace it with a new one.

2. The reason why the engine cannot be turned off:

The installation position of the throttle wire on the engine is appropriate; the throttle wire is broken; the throttle is not sensitive; the flameout wire cannot be touched. Remedy: reinstall the throttle cable; replace the new throttle cable; drip a small amount of engine oil to the active position of the throttle; check or replace the flameout cable.

The following is the maintenance method:
1. Oil Maintenance

Before using the lawn mower every time, check the oil level to see if it is between the upper and lower scales of the oil dipstick. The engine oil should be changed after 5 hours of use of the new machine, and once more after 10 hours of use, and the oil should be changed regularly according to the requirements of the manual. Oil change should be carried out when the engine is hot. Do not add too much oil, otherwise, there will be: black smoke, and insufficient power (too much carbon deposit in the cylinder, small spark plug gap). Engine overheating etc. Do not add too little oil, otherwise, there will be: engine gear noise, accelerated wear, and damage to the piston ring. There are even phenomena such as lava, which cause serious damage to the engine.

2. Maintenance of air filter

The air filter should be checked for dirt before and after each use and should be changed and washed frequently. If it is too dirty, it will cause difficulty in starting the engine, heavy black smoke, and insufficient power. If the filter element is paper, you can remove the filter element and dust off the dust attached to it; if the filter element is a sponge, after cleaning it with gasoline, add some lubricating oil to the filter element to keep the filter element wet Good for absorbing dust.

3. Maintenance of radiator
The main function of the radiator is to eliminate noise and dissipate heat. When the lawn mower is working, the flying grass clippings will adhere to the radiator, affecting its heat dissipation function, and in severe cases, it will cause cylinder scuffing and damage to the engine. Therefore, after each use of the lawn mower, the sundries on the radiator should be carefully cleaned.
