How to Suppress Sparks When Cutting With a Concrete Saw

Tackle small concrete jobs around the home yourself, and save money on contractors. You can create openings for doors or windows by cutting with a concrete saw. But first, make sure the wall is not load bearing and that its integrity will not be compromised by your alterations. A small amount of sparking from the saw is inevitable, but there are several things you can do to minimize sparking and make sawing safer.

Instructions

- 1
  Don your protective gear. Ensure all flammable materials have been removed from the area, and do not wear flammable clothing. Run the saw for 15 minutes on full throttle. Check that the blade runs true and there are no problems with the saw. Any problems or chips in the blade will increase sparking.
- 2
  Pick the correct blade for the job. Consult your hardware professional to ascertain whether the blade you are using is the right one. Using the wrong blade will increase sparking.
- 3
  Set the saw to a slower speed. The slower speed will reduce sparking and increase the longevity of your blade.
- 4
  Lubricate the blade shaft before use, and grease the rear wheel after every 40 hours of use. Tighten belts after every 2 hours of use, and return them to the original factory tension. Keeping your saw lubricated and the belt tight will keep your saw operating at optimal levels with little sparking.
