Saw chain is also called chain saw. After a period of use, the cutter teeth become dull due to wear, which will affect the sawing efficiency. Therefore, it is necessary to check regularly and file the saw chain in time. The following details how to file a saw chain with a round file.

First, we need to know the parameters of the cutter teeth.

As shown in the figure, cutter tooth parameters include upper plate angle, side plate angle, top plate cutting angle and cutting depth.

Upper plate angle: the angle between the top surface of the cutter tooth and the vertical plane; Side plate angle: the angle between the flank of the cutter tooth and the horizontal plane; Tangent angle: the included angle between the blade bevel and the horizontal plane; Cutting depth: the horizontal height difference between the upper end of the guard and the saw blade affects the single sawing depth and the load of the chainsaw.

Second, the specific method of sawing chain with circular file (subject to the actual cutter tooth parameters)

Usually, the saw chain of chainsaw uses a circular file (5/32) with an outer diameter of 4 mm, and the saw chain of chainsaw uses a circular file (3/ 16) with an outer diameter of 4.8 mm.

As shown in the figure, fix the guide plate, and stick the file on the saw blade so that it forms a 30-degree angle with the guide plate, and extend the outer diameter of the circular file at the tip of the saw blade 1/5.

Hold the handle tightly when filing and push the file away from the operator. When retracting the circular file, don't touch the saw blade, because the saw blade of the circular file is forward. If you retract it hard, it will damage the circular file. (Angle A is slightly greater than 90)

After filing the saw chain, it must be immersed in lubricating oil, and sawdust and sawdust must be washed off the saw chain. The saw chain can be put back on the guide plate for further use.
