Locksmith tool maintenance
(1) In order to prevent the file from wearing too fast, do not file the hard skin of the blank or the hardened surface of the workpiece with a file, but use other tools or the front end and side teeth of the stand first.
(2) When filing, use one side of the falling knife first, and then use the other side after this side is dull. Because used file teeth rust easily.
(3) When filing, make full use of the effective working face of the file to avoid local wear.
(4) The file cannot be used as a tool for disassembly, knocking and prying, so as to avoid the file being broken due to fragile materials.
(5) When using plastic files and small files, do not use too much force to prevent the files from breaking.
(6) The file should be waterproof and oil-proof. Files rust easily when they are wet with water. The file is easy to slip when working after being stained with oil.
(7) In the process of filing, if chips are found embedded in the file lines, they should be removed in time to avoid the chips scratching the machined surface. After the file is used up, brush off the remaining debris along the file line with a file brush or copper sheet to prevent rust. Never blow potato chips with your mouth to prevent them from flying into your eyes.
(8) When placing files, avoid collision with hard objects, avoid file overlapping and stacking, and prevent file damage.
