1. Installation method of electric jig saw blade
A jig saw is a kind of electric saw. It can cut metal and wood with different saw blades. Due to the width of the saw blade of the jig saw It is narrow, and can realize straight line cutting, small curve cutting, medium curve cutting and large curve cutting under different knife lifting gears. If it is to be used in different fields, the saw blade needs to be replaced, so how to change the saw blade for a jig saw?
1. The operation part for loosening and tightening the clamp is at the front of the handle, and the exterior is a black piece. This black part can be pulled up and rotated after being pulled out.
2. When inserting the saw blade, pull out this part upwards (about 1-2cm), then loosen it counterclockwise, tighten it clockwise, and generally loosen it for more than 3-5 turns counterclockwise. The part that enters the saw blade should be moved up to a sufficient height; at this time, insert the saw blade horizontally until it can no longer enter, and then rotate 90 degrees to make the horizontal saw blade face forward and backward. Then turn the dialed knob clockwise, about 3-5 turns, you can hear a rattling sound and then tighten it, then set the knob to the correct position and press it back to its original position.
3. In this way, the saw blade is installed, you can try the saw blade, and it can be clamped and not shaken.
Second, is the jig saw blade universal?
The jig saw can be replaced with a variety of saw blades, so can the saw blade of the jig saw be universal?
Generally speaking, the saw blade of a jig saw depends on the shape and size of the head, and the same size is universal, but if the length of the saw blade is different, or the material to be sawed is different, then the saw blade cannot be universal; In addition, the saw blade of the jig saw and other saws, such as the saw blade of the saber saw, are also not universal, because they have different interfaces.
Three, the use of electric jig saw skills
1. When using electric jig saw, you can choose saw blades with different thickness teeth according to the hardness of the workpiece material . In general, fine-tooth saw blades are selected for hard materials; coarse-tooth saw blades are selected for soft materials.
2. Before use, it should be idling for 2-3min to check whether the transmission part is working normally. Otherwise, it should be used after troubleshooting.
3. If abnormal sound or temperature rise is found during use, stop using it immediately, cut off the power supply for inspection, and use it after overhaul.
4. When sawing, the forward push should not be too violent, and the corner radius should not be too small to prevent the saw blade from breaking and causing accidents. If the saw blade is stuck, cut off the power immediately, exit and then continue to saw slowly.
