Impact drill and impact on spin to work. Impact drill can be used for natural stone or concrete. Compared with percussion drill, electric hand need minimum pressure to hard material, such as stone and concrete, especially the relatively hard concrete. Below small make up to introduce the impact drill the correct method of use: before operation, must check the power supply is consistent with the conventional V rated voltage on the electric tools, in order to avoid wrong received V power supply. , please check carefully before use percussion drill body insulation protection, auxiliary handle and depth gauge adjustment, etc. , the machine for the screw loose. And impact drill must be in accordance with the requirements of material into the phi -MM between the allowed range of alloy steel drill bit or general bit drilling. Beyond the scope of the bit is strictly prohibited. , impact drill, wire to protect good, forbidden ground mess dragged to prevent rolling bad, cut, more not allowed to pull the wire to the oil and water, prevent oil and water corrosion wires. , the use of percussion drill device must be equipped with the leakage switch socket, and check whether there is any breakage phenomenon on the power cord, use of abnormal impact drill leakage, vibration, high fever, or have a different sound, should immediately stop work, find a electrician check repair in time. , impact drill bit change, special wrench and lock the keys, bit drum percussion drill put an end to the use of special tools. , remember that not too hard or appear skewed when using percussion drill operation, prior to impaction bit right feet and adjust good impact drill depth, vertical, balance slowly while operating uniform pressure, use large bit cannot be forced. , mastering and operation good or poor steering control mechanism, elastic screw, drilling tapping function, etc.
