| Precautions for using electric circular saw | |
| 2020/8/3 | |
| The electric circular saw is a tool that uses a single-phase series motor as the power to drive the circular saw blade through a transmission mechanism to perform sawing operations. It has the characteristics of safety, reliability, reasonable structure, and high work efficiency. However, it is necessary to use as much care as possible to ensure that it is foolproof, so the routine operation of the electric circular saw should be continuously consolidated. Preparation before operation ①There should be no cracks or damages on the saw blade, shell, and handle. ②The cable cord and plug are intact, the switch action is normal, and the protective zero connection is correct, firm and reliable. ③Whether the saw blade is installed firmly, whether the bolts are tightened, and whether the inner and outer chucks clamp the saw blade tightly. Whether the plane of the saw blade is perpendicular to the horizontal axis of the electric circular saw. ④Check whether the movable protective cover rotates flexibly, whether it is deformed, whether it rubs against the circular saw blade, whether the connection is reliable, and whether it falls off during operation. ⑤Check whether the side handle is installed firmly and whether it will be loose during holding operation. ⑥Check whether the workpiece to be cut is firmly fixed. Operation precautions ①When starting, the electric circular saw must be in the suspended position. It will jump suddenly. It must be held with both hands. The fingers must not be placed in the switch position. The saw teeth must leave the workpiece to be cut to prevent the electric circular saw from jumping and touching the workpiece when it starts. ②After the electric circular saw is started, it should be left idling for a period of time to observe whether the saw blade is running normally, whether there is left and right swing, whether the electric circular saw vibrates too much, and whether the noise is normal. ③Be sure to pay attention to the position of the cable during the operation of the electric circular saw to prevent it from being cut and causing electric shock or short-circuit accidents. The cable should be bypassed and then connected to the power source. Keep your body away from the cable. ④When the electric circular saw is in the cutting operation, both hands must firmly hold the handle and side handle of the equipment. The fingers must not approach the high-speed rotating saw blade, and the operator's body must maintain a proper distance from the equipment. ⑤ Do not use an electric circular saw above the top of the head to prevent the electric circular saw or the cut workpiece from falling off and causing accidents. ⑥The new saw blade is generally flat. When cutting the road, select it within the range of 5℃～20℃ as needed. ⑦After the machine is started, run it without load for a while, check and confirm that the machine linkage is flexible and unimpeded. When working, the afterburner should be balanced and not too strong. |
