Precaution to be observed:

• Choose the correct blade for the material being cut.
• Secure the blade with the teeth pointing forward.
• Keep the blade rigid and the frame properly aligned.
• Cut using strong, steady strokes directed away from you.
• Use the entire length of the blade in each cutting stroke.
• Keep saw blades clean, and use light machine oil on the blade to
  keep it from overheating and breaking.
• Cut harder materials more slowly than soft materials.
• Clamp thin, flat pieces that require edge cutting.
• If you’re cutting pipe, always secure it in a vise before cutting
