How to install the electric circular saw blade? What are the precautions for electric circular saw operation?

Electric circular saw blades are the working tools of electric circular saws. They are divided into two types: longitudinal cutting and cross-sectional type. Standard diameter and qualified circular saw blades must be used. Saw blades made of high-speed steel and deformed or cracked blades are not available. Before use, the saw path should be corrected, and the saw teeth of the electric circular saw should be ground. The circular saw blade is also the most important part of the circular saw, so how to install the circular saw blade?

　　 How to install the electric circular saw blade

1. Remove the screws and remove the external pressure plate.

2. When installing the electric circular saw blade, make sure that the direction of the blade is consistent with the rotation direction of the blade (the arrow on the blade should point in the same direction as the arrow on the circular saw).

3. The diameter of one side of the boss of the inner pressure plate is 30 mm, and the diameter of the other side is 20 mm. Use the correct side according to the aperture of the saw blade you are using. Wrong installation may cause dangerous vibration.

4. It is best to use the special wrench provided with the electric circular saw manufacturer to disassemble or install the saw blade.

After the circular saw blade is installed, it should be checked whether the direction of rotation is consistent with the direction of the arrow marked on the moving cover, and do not install the circular saw blade backwards. The helical circular saw blade (longitudinal cutting type) is used to cut longitudinal fiber wood I straight shade circular saw blade (cross sectional type) to cut wood orthogonal to the fiber direction. The saw teeth of the circular saw blade should be kept sharp.

　　 Precautions for operation of electric circular saw

1. When starting, the electric circular saw must be in the suspended position, it will jump suddenly, it must be held by both hands, the finger must not be placed in the switch position, the saw teeth must leave the cut workpiece, to prevent the electric circular saw from jumping and touching the cut workpiece .

2. After starting, the electric circular saw should be idle for a period of time to observe whether the blade is operating normally, whether there is a phenomenon of left and right swing, whether the electric circular saw vibrates too much, and whether the noise is normal.

3. During the operation, the electric circular saw must pay attention to the position of its cable to prevent electric shock or short circuit accident caused by cutting. The cable should be bypassed before connecting to the power source, and the body should not be in contact with the cable.

4. When the electric circular saw is performing the cutting operation, both hands must firmly grip the handle and the side handle of the device. The fingers should not be close to the saw blade rotating at high speed, and the operator's body must be kept at an appropriate distance from the equipment.

5. Do not use the electric circular saw in a position higher than the top of the head to prevent the electric circular saw or the cut workpiece from falling off and causing accidents.

6. The new saw blade is generally flat. When opening the saw road, select within the range of 5 ° ～ 20 ° as needed .

7. After the implement is started, it should run for a while without load, check and confirm that the linkage of the implement is flexible and unobstructed. During operation, the afterburner should be balanced, and no excessive force should be applied.

The contents of how to install the electric circular saw blade and the precautions for the operation of the electric circular saw are introduced here for everyone. Whether you are installing the electric circular saw blade or using the electric circular saw, you should abide by the operating specifications so that it can be smoother. To carry out work to prevent accidents.
