German MOZART tools MOZART models MOZART prices

MOZART tools powered by electric motors or electromagnets, driving the working head through a transmission mechanism, are referred to as power tools. They are hand-held operating tools that use low-power electric motors or electromagnets as the power source to drive the working head via a transmission mechanism. Power tools are divided into two types: hand-held and portable. Hand-held power tools are more flexible, convenient, and widely used; many varieties have become essential tools for production and daily life. There are numerous power tool brands. According to their functions and applications, they are mainly classified into metal cutting power tools, grinding power tools, assembly power tools, and railway power tools. Common power tools include electric drills, electric grinders, electric wrenches and electric screwdrivers, electric hammers and impact drills, concrete vibrators, and electric planers.

MOZART tool types

1) Frame saw. Also known as a buck saw, it consists of an H-shaped wooden frame, twisted rope and toggle, saw blade, etc. The two ends of the saw blade are fixed to the frame with knobs, which can also be used to adjust the angle of the blade. After tightening the twisted rope, the saw blade is tensioned and ready for use. Frame saws are classified into coarse, medium, and fine types based on blade length and tooth pitch. Coarse saw blades are 650—750mm long, with a tooth pitch of 4—5mm; coarse saws are mainly used for cutting thicker wood. Medium saw blades are 550—650mm long, with a tooth pitch of 3—4mm; medium saws are mainly used for cutting thin wood or cutting tenons. Fine saw blades are 450—500mm long, with a tooth pitch of 2—3mm; fine saws are mainly used for cutting finer wood and cutting tenon shoulders. 2) Knife saw. A knife saw mainly consists of two parts: the saw edge and the saw handle. It can be classified into single-sided, double-sided, and back-backed knife saws. Single-sided knife saws have a blade length of 350mm, with teeth on one side. Depending on the function of the teeth, they can be divided into rip-cut and cross-cut types. Double-sided knife saws have a blade length of 300mm, with teeth on both sides; generally, one side is for rip-cutting and the other for cross-cutting. Back-backed knife saws have a blade plate length of 250—300mm. The back of the back-backed knife saw is reinforced with a steel strip, and the teeth are finer, available in rip-cut and cross-cut versions. 3) Groove saw. A groove saw consists of a handle and a saw blade, with the blade being approximately 200mm long. Groove saws are mainly used for cutting grooves in wood. 4) Panel saw. Also known as a hand saw, it consists of a handle and a saw blade. The blade is approximately 250—750mm long, with a tooth pitch of 3—4mm. Panel saws are mainly used for cutting wider wooden boards. 5) Narrow hand saw. The blade is narrow and long, with a pointed tip, and a length of approximately 300—400mm. Narrow hand saws are mainly used for cutting narrow holes and slots. 6) Coping saw. Also known as a fret saw, its structure is similar to that of a frame saw, but the blade is narrower (approximately 10mm), mainly used for cutting arcs, curves, and other shapes. 7) Wire saw. Also known as a bow saw, it is made by bending a bamboo strip into a bow shape and stretching a wire between the two ends. Saw-tooth-like projections are cut into the wire, using the sharp edges of these projections for cutting. The wire is approximately 200—600mm long, and the saw bow is 800—900mm long. Wire saws are mainly used for cutting complex curves and opening holes.

MOZART tool usage

1) Select the appropriate saw blade according to the workpiece. For example, use 14 teeth per inch for cutting solid or thick soft metals; use 18 teeth per inch for tool steel, iron pipes, hard metals, etc.; and 24 teeth per inch is suitable for cutting metal sheets, metal pipes, and thin iron bars. 2) Push forward to cut, and lift gently when pulling back. 3) Select a wrench of appropriate size according to the nature of the work. 4) When using an adjustable wrench, apply force towards the fixed jaw, never towards the movable jaw. 5) If the wrench jaws are worn or slip during use, do not continue to use them to avoid slipping. 6) Do not use a wrench as a hammer for striking. 5) Do not fit a pipe over the end of the wrench handle to increase torque. 7) Press the inner side of the first leg of the square against the edge of the wooden board, and draw along the inner side of the second leg with a pencil to mark a perpendicular line. 8) Select a screwdriver appropriate for the size and shape of the screw head slot. 9) Do not strike the screwdriver handle with a hammer; replace handles immediately if damaged. 10) Do not use a screwdriver as a chisel or lever. 11) Use an electrician's screwdriver to test current; do not use ordinary screwdrivers to test high voltage. 12) Do not grind the tip of a screwdriver to avoid damaging the hardened surface. 13) Do not keep screwdrivers in shirt or trouser pockets to avoid injury from collision or falling.

MOZART tool operation

1) The single-phase power cord for mobile electric machinery and handheld electric tools must use a three-core flexible rubber cable, and the three-phase power cord must use a four-core rubber cable; during wiring, the cable sheath shall be inserted into the equipment's junction box and secured. 2) Before using electric tools, check the following items: no cracks or damage to the housing and handle; correct and secure connection of the protective grounding wire or neutral wire; intact cable or flexible cord; intact plug; normal, flexible, and undamaged switch operation; intact electrical protection devices; intact mechanical guards; and flexible rotating parts. 3) The insulation resistance of electric tools shall be measured regularly using a megohmmeter with 500V; if the insulation resistance between live parts and the housing is less than 2M Ω, maintenance must be performed. 4) After repairing the electrical parts of an electric tool, insulation resistance measurement and dielectric strength testing must be carried out; the test voltage is 380V, and the test duration is 1 minutes. 5) The electrical circuits connecting electric machinery and tools shall have separate switches or sockets, and residual current operated protective devices shall be installed; the metal housing shall be grounded; it is strictly prohibited to connect multiple devices to a single switch. 6) The rated residual operating current of current-type residual current operated protective devices shall not exceed 30mA, and the operating time shall not exceed 0.1 seconds; the rated residual operating voltage of voltage-type residual current operated protective devices shall not exceed 36V. 7) The operating switch of motor-driven tools shall be located within easy reach of the operator. During breaks, after work, or in case of sudden power failure during operation, the power supply switch shall be disconnected. 8) When using portable or mobile electric tools, wear insulating gloves or stand on an insulating mat; when moving the tool, do not lift it by the power cord or the rotating parts. 9) When using Class III insulated electric tools in damp or acid-containing environments, as well as inside metal containers, reliable insulation measures must be taken and a dedicated supervisor assigned. The switch of the electric tool shall be placed within easy reach of the supervisor. 10) The magnetic surface of a magnetic chuck drill shall be flat, clean, and rust-free; when performing side drilling or overhead drilling, measures shall be taken to prevent the drill body from falling in case of power loss. 11) When using an electric wrench, ensure the reaction torque support is firmly positioned and the nut is securely tightened before starting.
