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 were 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.
All fluids are at proper levels.
Blade shaft bearings should be free of end and radial play.
V-Belts should be properly tensioned and pulleys checked for excessive wear.
Lead-off adjustments is set correctly, to allow the blade to travel straight.
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 sufficient water flow. The water pumps on concrete saws are “booster” pumps only and are not adequate as a primary pressure source. An adequate water supply is required for wet cutting blades to maintain blade life and cutting efficiency.
DO FOLLOW THE MANUFACTURER’S RECOMMENDED PULLEY SIE AND OPERATING SPEEDS. FOR SPECIFIC BLADE DIAMETERS, REFER TO MANUFACTURER’S OPERATING MANUAL.
Do operate saw with proper safety attire, i.e., safety glasses, safety helmet, safety shoes, hearing protection.
Do examine blade periodically for cracks in the steel center or segments and for 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. This indicates segment damage or loss or a damaged arbor hole.
Don’t use mounting flanges that 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 minimum requirements set forth in the manufacturer’s machine operating manual.
Misalignment of the blade results in loss of blade side clearance and proper blade tension.
Loose or worn blade shaft bearings cause short diamond blade life and may cause segment loss.
Use of worn pulleys or improper feed belt tension causes loss of proper operating speed and reduced blade efficiency.
Restricted coolant flow causes excessive heat, poor blade performance, and possible segment loss.
Don’t cut dry with blades recommended for wet cutting.
Don’t use blotters with diamond saw blades.
Don’t operate machine with a damaged or open blade guard.
