How to properly operate a hand saw

①When installing the band saw blade, the tip of the tooth should be pushed forward. The tension level of the band saw blade should be moderate. If it is too tight, it is very easy to break in application; if it is too loose, it is very easy to distort and shake in application, making the saw seam inclined, and it is also very easy to break the band saw blade.

②When using a hand saw, generally hold the handle of the saw with your left hand and hold the front of the saw bow with your right hand.

Because the structure of the saw handle is different, there are two ways to hold the saw handle with the left hand. When pushing the saw, the human body. Carry out sawing while reducing jagged damage at the same time.

③Whether the way of sawing is appropriate will immediately endanger the quality of sawing. The starting saw can be selected from the far side or the near side. When starting sawing, the viewing angle between the band saw blade and the product workpiece is about 10*~15°, and the viewing angle should not be too large. The reciprocating rate of sawing should be 20~40 times/min, and the working length of the band saw blade should generally not be less than 2/3 of the length of the band saw blade.

④ The sawing round bar can be sawed from scratch. When sawing a hollow pipe, it is not possible to start sawing from the beginning one by one, and it should be terminated when the sawing reaches the inner cavity of the pipe.

Rotate the pipe to the direction of the push saw for a certain angle of view and then saw it again, so as to proceed successively until the sawing is completed.
