The blade of the gasoline chain saw machine becomes dull after a period of use, at which time the blade needs to be polished to make it sharp again. The correct grinding method can not only improve the efficiency of the blade, but also extend its service life. Today Xiaobian will introduce the gasoline chain saw machine blade grinding skills, to help you easily polish the blade more sharp.

1. Prepare the polishing tools. Tools such as a small file, a piece of fine sandpaper and a whetstone or wheel, these are the basic tools needed. Choosing the right tool can improve efficiency and quality, making the blade sharper.

2. Clean the blade. Before sanding, you need to clean the blade. Use a brush, cloth, or other suitable cleaning tool to wipe the dust and stain off the blade. This can facilitate the observation of the gasoline chain saw machine blade itself, so as to better grinding.

3. Polish the blade. The grinding process can be divided into coarse grinding and fine grinding two stages. In most cases, coarse grinding and fine grinding take about 20 to 30 minutes each. The exact time depends on the Angle and bluntness of the blade. The following are two stages of grinding methods:

Grind coarsely. The purpose of the roughing stage is to re-polish the cuts and serrations of the blade. The use of a file for rough grinding helps to create a better cutting Angle and improve cutting efficiency. When working, the blade should be placed on a flat surface that can be fixed.

Then, place the file on the cut of the blade at an appropriate Angle and work slowly from the tip to the back in the same direction. It is not appropriate to exert too much force, and maintain moderate pressure.

It should be noted that a certain amount of patience and meticulousness should be maintained in the polishing process, especially the careful polishing quality of every part of the blade, which can ensure the sharpness of the blade edge.

Grind carefully. The purpose of the fine grinding stage is to sharpen the gasoline chain saw machine blade. This requires the use of abrasive materials such as sandpaper or whetstone. As with rough grinding, the blade needs to be secured. Next, grind slowly along the blade with the abrasive, again maintaining moderate pressure.

It is worth noting that a lot of sand on the surface of the sandpaper will adhere to the blade, so it is necessary to wipe the blade regularly in order to achieve the desired effect.

4. Check the blade. After polishing, the blade needs to be inspected to see if there are still scratches, bumps or other defects that can not be solved, and if it is determined that there is no problem, it is installed back to the hedge machine, which is used to trim the hedge or lawn.

Grinding the blade every other period to maintain its sharpness is also an important means of maintaining the blade.

Polishing gasoline chain saw machine blades requires attention to skills and methods. Only with the right tools and in accordance with the correct method of grinding, the blade can achieve a higher sharpness. At the same time, grinding the blade regularly is to ensure the normal operation of the machine, and it is recommended that you do not neglect in use.
