Each category has Different models. For the commonly used tools, it is necessary to use the correct method and maintenance management to bring greater convenience to people. Let ’s take a closer look at the common tools used in the next set.
Metalworking hand bow saw: Use appropriate saw blades to match the work, such as solid or thick soft metal with 14 teeth per inch;
Tool steel, iron pipe, hard metal, etc. are used for 18 teeth per inch; and 24 teeth per inch are suitable for sawing metal plates, metal pipes, and thin iron bars.
Wrench: A proper size wrench should be selected according to the nature of the work. When using the adjustable wrench, apply force to the fixed side, and do not apply force to the movable side. If the opening of the wrench is worn or slipping during use, do not continue to use it to avoid injury due to slipping. Do not use a spanner as an iron hammer. Do not put a pipe on the handle end of the wrench to increase the torque of the wrench.
Screwdriver: Should match the size and shape of the groove of the screw head, choose an appropriate screwdriver. The handle of the driver should not be hit with a hammer, and the damaged handle should be replaced immediately. Do not use the screwdriver as a ladle or leverage. The electric current shall be tested by an electric screwdriver, and the high voltage power shall not be tested by a general screwdriver. Shida tool manufacturers remind users that when using a screwdriver, the blade of the screwdriver must not be ground to avoid damaging the hardened surface. The driver should not be placed in the pockets of clothes or pants to avoid injury in the event of a collision or fall.
Pliers: Pliers are only used to fasten, insert and remove various pins, nails, and cut or tighten various wires. Pliers should not be used to tighten or strike bolts or nuts. Do not tap or extend the handle to increase the clamping or cutting force at the handle of the pliers.
Portable electric drill: The drill bit must be tightened with a wrench that conforms to the specifications. Before starting the electric drill switch, the electric drill must be held firmly. When the electric drill is not in use or when the drill is replaced, the power should be turned off before putting it down. The drill bit should be removed first at the end of work. Pressure on the drill bit should be moderate. Too much force may break the drill bit or reduce the speed of the drill bit. If it is too small, the drill bit will wear easily. When drilling fast, the pressure must be light in order to perforate smoothly. When drilling small work, the work piece should be fixed by fixture.
