The purpose of this tool is to cut through material that is too thin to be cut using a band-saw, that requires less cutting force, or is oddly shaped. Safety glasses should always be worn when using this tool. When using this tool, ensure that your work piece is securely held in place. Be cautious of the sharp edges that are formed from the hack-saw. Pay special attention to the type of saw blade you are using. There are various tooth sizes and styles that will dictate what type of application they are meant for. For example, a coarse tooth blade may be used for softer materials such as plastics, wood or aluminum. A fine tooth blade may be used on harder materials such as steels.


First identify the type of blade that is required for your particular application. Secure the work piece to a firm surface. Gently rest the hacksaw blade against the surface of the material to be cut. With slow and light strokes, pull the saw towards you. This will cut a small groove that will assist with cutting in the intended location. Once a sufficient groove has been established, the sawing action can commence. Bring the saw towards you and place the teeth on the part. Apply force in a smooth pushing motion. Once you are out of stroke on the saw blade, gently bring the saw blade back towards you. Repeat this motion until the operation is complete. Use a file to remove any burrs that were left by the saw blade. Use a hand brush and dust pan to clean up any debris produced during this operation. Return the hack-saw to its proper location. If a new blade is needed, loosen the screw typically located near the hack-saw handle to relieve tension on the blade. Remove the blade from the rear hook followed by the front hook. When placing the new blade on to the hack-saw, ensure that the teeth are pointed away from the handle and that the arrow printed on the blade faces away from the handle. Place the blade on the two hooks and tighten the screw to secure the blade in place.
