⅜ Select a saw blade of the most appropriate length. Ideally, the length protruding from the base of the saw blade after subtracting the stroke should be larger than the material (see Fig. 16 and Fig. 18). If you cut a large pipe, large block of wood, etc., that exceeds the cutting capacity of a blade; there is a risk that the blade may contact with the inner wall of the pipe, wood, etc., resulting in damage. (Fig. 17, Fig. 19) ⅜ To maximize cutting efficiency for the materials you are using and working conditions, adjust the speed of the saw blade and the switching to swing cutting. 1. Cutting metallic materials CAUTION: ⅜ Press the base firmly against the workpiece. ⅜ Never apply any unreasonable force to the saw blade when cutting. Doing so can easily break the blade. (1) Fasten a workpiece firmly before operation. (Fig. 20) (2) When cutting metallic materials, use proper machine oil (turbine oil, etc.). When not using liquid machine oil, apply grease over the workpiece. CAUTION: The service life of the saw blade will be drastically shortened if you don't use machine oil. (3) Use the dial to adjust the speed of the saw blade to suit your working conditions and materials. (4) You can cut smoothly if you set the change lever position to straight cutting (Fig. 14).
