The characteristics of the brush cutter and how to use the brush cutter

Brush cutters, also known as lawn mowers, are a type of garden machinery used for woodland cleaning, young forest tending, secondary forest transformation, and forest tending felling to cut shrubs, weeds, pruning branches, cutting trails, and cutting bamboo. The brush cutter is equipped with some replaceable additional devices or equipment, which can also be used to harvest crops such as rice and wheat. The development of the brush cutter is closely related to the development of small power machinery. Today, the editor mainly talks about the characteristics of the brush cutter and the method of using the brush cutter.

Characteristics of brush cutter

It is characterized by flat work, simple operation, strong cutting ability for the objects that need to be cut, mainly grasses, and is suitable for high-yield pastures and large parks. The lawn mower cuts the grass by the relative shearing movement of the movable knife and the fixed knife on the cutter. It is characterized by neat stubble cutting and low power required, but it has poor adaptability to pasture and is easy to block. It is suitable for flat and natural grasslands. And artificial grassland operations. Production and use of rotary lawn mowers began in the mid-1980s. Rely on the blade on the high-speed rotating cutter head to cut the forage. With the improvement of technology, the working ability of the newly improved lawn mower products has been greatly enhanced, and the speed has been greatly improved, which saves the working time of the weeding workers and saves a lot of human resources, such as the Crep brush cutter.

Use of brush cutter

1. General safety measures

1.1. It is forbidden to use indoors;

1.2. Keep a safe distance from flammable materials not less than 1 meter;

1.3. Smoking is prohibited when refueling, the engine must be stopped, and gasoline overflow is prohibited;

1.4. Wear protective glasses and protective equipment when working, and use shoulder straps. If there are breaks, cracks or bends, they must not be used, nor can they be used without a protective cover;

1.5. Before use, remove the rocks and other hard objects from the ground, and keep it at least 1.5 meters away from people and animals when using it;

1.6. Keep hands and feet away from the machine before turning and stopping.

2. Check before operation

2.1. Check the fuel level from the outside of the fuel tank. If the fuel level is low, add fuel to the upper limit. The fuel is formulated with a 25:1 mixing ratio of unleaded gasoline and two-stroke engine oil. Pure gasoline and gasoline containing impurities must not be used.

2.2. Air filter Check the dirt of the air filter element and clean it if there is dirt.

2.3. Check the free gap of the throttle cable at the end and check the operation of the throttle handle is stable.

2.4. Blade check whether the blade installation nut is loose, tighten the nut if necessary; check whether the blade has cracks, nicks, bends and wear, and replace it if necessary.

2.5. Cutterhead guard check whether the guard is loose, if necessary, tighten the safety bolt of the guard; check whether the guard is damaged, and replace it if necessary.

2.6. Pull up the release lever of the quick release device and check whether the hook is released, and put the hook in place.

3. operating procedures

3.1. When mowing the grass with the mowing head, ensure that the nylon rope of the mowing head extends 5-10cm outside the mowing head. If it is too long, the service life of the gasoline engine will be affected due to the large load, and the damage of the grass barrier will be formed. ; If it is too short, the job compliance will be reduced.

3.2. After the nylon rope is worn and shortened, in the process of normal use, you only need to touch the mowing head quietly into the air, and the nylon rope will actively stretch out. If the length is not enough, you can repeat the touch several times until the nylon The rope length is 5-10cm. After the nylon rope is used up, the cutter head can be disassembled, and the new nylon rope can be wound on the rope wheel and installed.

3.3. When cutting grass with a blade, do not extend the entire blade into the grass. For ordinary lawns, extend into 1/2 of the diameter of the blade. For grass with hard stems, extend into 1/3 of the diameter of the blade. can.

3.4. When cutting shrubs with blades, ordinary shrubs should stop cutting along the periphery of the shrubs in the uniform water level. When cutting thick shrubs, cut an opening in the direction where the shrubs fell, and the depth of the opening should be 1 of the diameter of the shrub. /3 or so, then cut off the bush from the other side of the bush. Such cutting not only ensures that the blade will not be clamped during the cutting process, but also controls the direction in which the bushes fall.

4. maintenance

4.1. Before using the lawn mower, check the oil level to see if it is between the upper and lower scales of the oil dipstick.

4.2. The oil should be changed after 5 hours of use for the new machine, and the oil should be changed again after 10 hours of use, and the oil should be changed regularly according to the requirements of the manual.

4.3. The oil change should be carried out when the engine is in a warm state. Do not add too much oil, otherwise there will be large black smoke, insufficient power (excessive carbon deposit in the cylinder, small spark plug gap), and engine overheating.

4.4. The engine oil should not be too little, otherwise, the engine gear will be noisy, the piston ring will be worn and damaged at an accelerated rate, and even the pull will appear, causing serious damage to the engine. Pay attention to safety when using it. Therefore, check and test beforehand.

4.5. Remove the spark plug, clean up the carbon deposits, and measure (electrode) gap between 0.6 to 0.7 mm;

4.6. Repair the fuel filter and clean the fuel tank. Pour out the engine fuel, take out the filter, and clean it gently; remove the moisture and dirt attached to the fuel tank;

4.7. Heat sink, check whether the heat sink is dirty through the engine hood, and clean it if it is dirty.

4.8. Fuel pipe, check the fuel pipe, if it is aging or leaking, replace it in time.

4.9. Replace the blade and nylon disc in time.

The use of the brush cutter should not be ignored. I hope you can operate according to the requirements. If you have any questions, you can consult us
