All manufacturers of diamond blades are very concerned that their products are used in a safe manner. The following is a list of Do’s and Don’ts for concrete and masonry dry sawing. This is provided with the intention of eliminating hazardous conditions or practices. Please take time to read and understand its principles.
IMPORTANT: Always wear proper safety equipment; wear safety glasses, safety footwear, snug-fitting clothing, hearing and head protection, and respiratory equipment where required.
Dry Cutting Do’s
- Do follow manufacturer’s recommendation regarding specification for material to be cut and suitability for dry cutting applications.
- Do inspect the diamond saw blade for damage that may have occurred during shipment or damage due to previous use.
- Do inspect the diamond blade periodically during use for core flatness, fatigue cracks, segment damage, undercutting and damage to the arbor hole.
- Do check the mounting flanges to be sure that they are of equal or correct diameter, that they do not show excessive wear, and that they are flat.
- Do be sure that the diamond blade is mounted on a correct diameter blade shaft between proper blade flanges and is securely hand tightened with the wrench provided or an adjustable wrench no longer than 8".
- Do check for proper saw machine conditions. Spindle bearings should be free of end and radial play. Consult the operating manual from the saw manufacturer for proper machine maintenance conditions.
- Do follow the manufacturer’s recommendation for operating speeds for specific blade diameters.
- Do maintain a firm grip on hand-held saws during cutting operation.
- Do wear proper safety equipment at all times. Always wear safety glasses, safety footwear, snug fitting clothing, hearing and head protection, and respiratory equipment where required.
Dry Cutting Don’ts
- Don’t cut dry except with a blade specifically designated for dry cutting by the manufacturer.
- Don’t force blade onto machine blade shaft, alter the size of the mounting hole, or tighten mounting nut excessively. The use of bushings to reduce the arbor hole size is not recommended for diamond blades used on high speed saws.
- Don’t exceed the maximum operating speed established for the diamond blade.
- Don’t operate a saw without proper safety guards in place. NEVER OPERATE ANY SAW, WET OR DRY, WITHOUT A BLADE GUARD!
- Don’t stand in direct line with dry diamond or abrasive blades during start-up or operation.
- Don’t cut or grind with the sides of a diamond blade.
- Don’t force the blade into the material; allow the blade to cut at its own speed. Forcing the blade may cause overheating or blade damage.
- Don’t make long continuous cuts with a dry diamond blade. Allow the blade to cool by turning in air every few minutes. The harder the material being cut, the more often the blade should be allowed to cool.
- Don’t use the blade to cut material other than that recommended by the manufacturer for that specific blade type.
- Don’t use the blade on a type of saw other than that specified by the manufacturer.
- Don’t allow the blade to deflect in the cut.
- Don’t attempt to cut curves or radii.
