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 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.
Wet Cutting Do’s
- Do follow manufacturer’s recommended blade specifications for material to be cut.
- Do inspect the diamond blade for damage that may have occurred during shipment or damage due to previous use.
- Do check mounting flanges for equal diameter, excess wear and flatness. Mounting flanges must have adequate relief around arbor hole.
- Do be sure that the diamond saw blade is mounted on a correct diameter blade shaft between proper blade flanges and is securely hand-tightened with a wrench.
- Do check the saw for proper operating conditions:
A. All fluids are at proper levels.
B. Blade shaft bearings should be free of end and radial play.
C. V-belts should be properly tensioned and pulleys checked for excessive wear.
D. Lead off adjustment is set correctly, to allow the blade to travel straight.
E. Do operate with blade guard in place and properly secured.
- Do be sure there is a continuous water flow to each side of the blade. Gravity feed does not supply a sufficient water flow. The water pumps on concrete saws are “booster” pumps only and are not adequate as a primary pressure source. An adequate coolant supply is required for wet cutting blades to maintain blade life and cutting efficiency.
- DO FOLLOW THE MANUFACTURER’S RECOMMENDED PULLEY SIZES AND OPERATING SPEEDS. FOR SPECIFIC BLADE DIAMETERS, REFER TO MANUFACTURER’S OPERATING MANUAL.
- Do operate the saw with proper safety attire, i.e., safety glasses, safety helmet, safety shoes and hearing protection.
- Do examine blade periodically for cracks in the steel center or segments, or excessive wear under the segments.
Wet Cutting Don’ts
- Don’t use a diamond saw blade without checking manufacturer’s recommendations for the material to be cut. Improper selection can cause excessive blade wear and possible damage to the diamond saw blade and/or machine, and create an unsafe operating condition.
- Don’t use a new diamond saw blade or remount a used blade which has a core that is not flat or is cracked, which shows segment damage or loss, or which has a damaged arbor hole.
- Don’t use mounting flanges on which the bearing surfaces are not clean and flat.
- Don’t force blade onto machine blade shaft or mount blade on undersized blade shaft. Either condition can result in unsafe operating conditions and excessive blade wear.
- Don’t mount blade on machine that does not meet the minimum requirements set forth in the manufacturer’s machine operating manual.
