1. Before installing the drill bit, first press down the chuck under the eye of the hammer bit to the end to separate the chuck and the drill eye, then insert the drill bit into the eye, and then release the chuck to return it. 2. When installing, insert the drill directly into the hammer chuck. 3. Turn left and right until the drill bit is automatically locked. 4. Pull the drill bit to determine whether it is properly locked. 5. After the installation, lift the electric hammer to force the drill bit against the wall or the ground to test drill. If there is obvious impact, it means that the drill bit is installed in place. Otherwise, it will be reinstalled. The difference between electric hammer bit and electric drill bit 1. The material of the drill is different. The center of the head of the electric hammer bit is inlaid with a piece of hard alloy, and the whole body of the electric drill bit is made of high-speed steel. 2. Different shapes. Electric drill bits are generally of equal diameter, and the diameter of the carbide outer edge of the electric hammer bit is slightly larger than the diameter of the drill body. There are various shapes due to the different connection forms with the electric hammer, such as square, triangle, and spiral . 3. Different cutting edges. The cutting edge of the electric drill is used for metal cutting. It has a certain angle and slope, and the cutting edge is sharp, while the electric hammer drill has no cutting edge, and the two sides are only chamfered. In addition, if the electric hammer bit is ground into an electric drill bit, it can also be used to drill holes on the wall. Electric hammer safe operation method 1. Personal protection when using electric hammer 1. The operator should wear protective glasses to protect his eyes, and wear a protective mask when working with the face up. 2. Keep earplugs in place for long-term operations to mitigate the effects of noise. 3. The drill bit is in a hot state after long-term operation, and you should pay attention to burn your skin when replacing it. 4. The side handle should be used during operation to operate with both hands to prevent the arm from being sprained by the reaction force during blocking. 5. When working on a ladder or working at a high place, measures for falling from a high place should be taken, and the ladder should be supported by ground personnel. 2. Matters needing attention before operation 1. Confirm whether the power supply connected to the site matches the nameplate of the electric hammer. Whether there is a leakage protector. 2. The drill bit and the gripper should be adapted and properly installed. 3. When drilling walls, ceilings, and floors, you should first confirm whether there are buried cables or pipes. 4. When working in high places, pay full attention to the safety of the objects and pedestrians below, and set warning signs if necessary. 5. Confirm whether the switch on the hammer is cut off. If the power switch is turned on, the power tool will turn unexpectedly immediately when the plug is inserted into the power socket, which may cause personal injury. 6. If the working place is far away from the power source, when the cable needs to be extended, sufficient capacity should be used to install a qualified extension cable. The extension cable should be elevated or pass through measures to prevent the cable from being damaged by rolling.
