What should you do before start cutting with a circular saw?

Back to top
  • Wear safety glasses or goggles, or a face shield (with safety glasses or goggles).
  • Wear an approved respirator or dust mask when exposed to harmful or nuisance dusts.
  • Use appropriate hearing protection equipment in noisy areas.
  • Check the retracting lower blade guard to make certain it works freely.
  • Ensure that the blade that you have selected is sharp enough to do the job. Sharp blades work better and are safer.
  • Check the saw for proper blade rotation.
  • Set the depth of the blade, while the saw is unplugged, and lock it at a depth so that the lowest tooth does not extend more than about 0.3 cm (1/8") beneath the wood.
  • Keep all cords clear of cutting area.
  • Circular saws are designed for right-hand operation; left-handed operation will demand more care to operate safely.

  • Check the retracting lower blade guard frequently to make certain it works freely. It should enclose the teeth as completely as possible, and cover the unused portion of the blade when cutting.

  • Use two hands to operate saws – one on a trigger switch and the other on a front knob handle.
  • Keep motor free from accumulation of dust and chips.
  • Select the correct blade for stock being cut and allow it to cut steadily. Do not force it.
  • Secure stock being cut to avoid movement.
