Impact drill belongs to high speed electric tools, improper use or wear labor protection is not easy to cause personal injury, so use or operate the machine, safe operating procedures must be carried out in the training, improve the awareness and safety protection. The use of percussion drill is analysed for everybody today. Mainly applies to the concrete floor, wall, brick, stone, wood and multilayer material impact on the punch; Also can be conducted on wood, metal, ceramic and plastic drilling and tapping and equipped with electronic speed equipment for cis/reverse, and other functions. Impact drill for double insulation design, safe and reliable operation, when using, do not need to use protective earth (After zero)Single-phase diode, the use of plug, when using insulation can not wear insulating gloves or shoes. To make the operation convenient, flexible and powerful, generally with the auxiliary handle percussion drill. Due to the impact electric drill adopts double insulation, no grounding (After zero)Protection, so should pay special attention to protecting rubber sets of cables. Portable electric drill, must hold the drill handle, moves can't drag cabtyre cable. Cabtyre cable can't let the wheel rolling rolling and feet; To prevent the mouse biting. Impact drill motor voltage with a V -V and V -V two different voltage, micro switch on-off control and motor speed 2 different speed, equipped with good or poor steering control mechanism, elastic screw and tapping etc. Function. ()Before operation must check to see if the power supply are in conformity with the conventional V rated voltage on the electric tools, in order to avoid wrong received V power supply. ()Please check carefully before using the impact electric drill body insulation protection, auxiliary handle and depth gauge adjustment, etc. , the machine for the screw loose. ()Impact drill must load phi - according to the requirements of materialMM between the allowed range of alloy steel drill bit or general bit drilling. Beyond the scope of the bit is strictly prohibited. ()Impact electric drill wire to protect good, it is strictly prohibited 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. ()Using impact electric drill device must be equipped with the leakage switch socket, and check whether there is any breakage phenomenon on the power cord, found that the impact of using electric drill abnormal leakage, vibration, high fever, or a different sound, should immediately stop work, find a electrician check repair in time. ()Impact drill bit change, application of special wrench and lock the keys, bit drum percussion drill put an end to the use of special tools. ()Remember not overexert when using impact electric drill or appear skewed operation, prior to impaction bit right feet and adjust good impact electric drill depth, vertical, balance slowly while operating uniform pressure, use large bit cannot be forced. ()Master and operation good or poor steering control mechanism, elastic screw, drilling tapping function, etc.
