The use of brush cutter common sense and how to choose

lawn mower, the main purpose is to cut grass. It is used in garden decoration pruning, grass greening pruning, urban streets, highway green belts, green scenic spots, garden pruning, field weeding, especially in parks and grasslands, football fields and other grasslands, private villa gardens, as well as agriculture, forestry and animal husbandry grounds and other aspects of vegetation trimming.

With the continuous development of science and technology, the use of lawn mowers is more and more extensive. Take the side hanging, knacker-type lawn mower, it is more used for rice, wheat, corn, sugar cane, beans, highland barley, herbs and other crops harvest, bush weeds, tea tree cutting, especially suitable for hilly areas, high slope terraces, triangular land, mud, woodland harvesting, cutting and trimming operations.

First: Whether it is a side-hanging lawn mower or a knife-type lawn mower, before operation, please connect the parts firmly according to the operating instructions, especially the working blade fillet nut, be sure to tighten.
Two: Check whether the fuel is enough, to accurately fill, two-stroke lawnmower fill mixed oil, gasoline, two-stroke oil mix, the ratio of 25:1, four-stroke lawnmower fill pure gasoline in the fuel tank, the fuel tank fill four-stroke oil, it is best to use lawnmower special oil.
Three: Start the Gasoline Engine, run at low speed or idle for 3-5 minutes, so that the gasoline engine is fully preheated before operation to better protect the gasoline engine.
Four: Before the operation, adjust the length of the strap according to their own characteristics, the lawn mower should be located on the right side of the operator, the operator needs to stand up straight naturally, the left and right hands respectively hold the left and right hands (side hanging) or the front and back hands (knapper). The lever is tilted forward and the blade is basically parallel to the ground at a distance of about 3-5 cm, which helps the operator maintain balance and effectively control the operation.

‍ in the process
1: The operation of cutting grass with the grass head should ensure that the nylon rope extends out of the grass head wheel 5-10 cm, if too long, it will affect the service life of the gasoline engine because of the large load, and cause damage to the grass board; If it is too short, the operation efficiency will be reduced.
Two: Do not extend the entire blade into the grass, general lawns, extend into 1/2 of the diameter of the blade, grass stems harder grass, extend into 1/3 of the diameter of the blade.
Generally, the shrub should be cut along the perimeter of the shrub in the same horizontal plane, and when cutting the thicker shrub, a cut should be made in the direction of the shrub falling first, the depth of the mouth is about 1/3 of the diameter of the shrub, and then the shrub will be cut off from the other side of the shrub. This cut not only ensures that the blade will not be caught in the cutting process, but also controls the direction of the bush's fall. ‍

Attention:
It can only be used for cutting grass, and is strictly prohibited for cutting shrubs. Do not use a two-pronged blade to cut shrubs. The diameter of the bush cut by the three-toothed blade should not exceed 1 cm. Carbide multi-tooth blade cutting bush should not exceed 6 cm.
Four: Use a blade to harvest rice, wheat and other crops to use a 36-tooth or 40-tooth blade, and install a rice support device. When harvesting, increase the throttle to 1/3, 1/2 or basically fully open, after the blade runs smoothly, feed the knife at the front end of the opening of the rice support device, cut straight and horizontal from right to left, the speed is moderate, the force is uniform, and the middle can not stop, otherwise, the rice support device will wind the straw causing the blade stuck. The cutting width should be moderate, not too thick and too wide, and the rice stubble should not be left too high, otherwise it will reduce the efficiency of the harvesting operation, and cause the phenomenon of irregular harvesting.
Five: Harvesting and placing operation ① Push the first cut of rice to the left, place the right side of the handle, so that the left opening of the rice holder can be tilted downward to place the harvested rice ② Use the same operation method as the first cut of the second cut of rice can be neatly placed on the first cut of rice. And so on, three times for a pile, so that the harvested rice piles placed, easy to bundle, collection.
Attention:
· Do not panic when the rice support is wrapped in straw, the blade is stuck or the blade suddenly vibrates, and should be handled calmly to avoid accidents. · In such cases, the gasoline engine should be turned off immediately. · Place the whole machine on a wide ground, clean the straw wrapped in the rice buttress and blade, check whether the blade has distortion, cracks, gaps, etc., check whether the fixed blade is loose, if the above, please replace the blade immediately and tighten the wire nut.

Warning operation, with the operator as the center, within a radius of 15 meters, do not let non-operators and animals close to avoid accidents. It is strictly forbidden to swing or open the bow from left to right during operation. Please operate with caution to avoid accidents.

After job
After each use, the whole machine must be cleaned and cleaned to keep it dry and clean.
one Empty the gas tank in a ventilated area and clean it.
2. Drain the carburetor, otherwise the carburetor pump film will stick, affecting the next start.
3. Start the engine until the engine automatically shuts off to completely drain the gasoline from the fuel system.
4. Thoroughly clean the entire machine, especially the cylinder heat sink and air filter.
5. Lubricate each lubricating point of the cutting machine.
6. Keep the machine in a dry and safe place to prevent contact with unrelated personnel. ‍
