1) What type of material are you cutting?
2) What type of equipment and what horsepower is being used?
3) Are you cutting wet or dry?
4) What is the most important to you - the initial price of the blade or the cost per cut? |

|
|
| * | Dry cutting blade can be used wet or dry. |
| * | Use dry blade Only for shallow cutting (1" to 2" deep) or step cutting
(making several shallow passes to reach the full depth required). |
| * | After every 10 to 15 seconds of cutting, take pressure off the blade and allow it to run back up to full speed for several seconds |
|
|
|
 |
|
|
| * | This blade must be used with water to prevent from excessive heating. |
| * | Using water on the blade also reduces dust and helps to remove cuttings. |

All manufacturers of diamond blades are very concerned that their products are use in a safe manner.
The following is a list of Do's and Don'ts for your working. This is provided with intention of eliminating
dangerous conditions or practices. Please take time to read and understand its principles. |
|
|
 |
|
|
| * | Carefully follow manufacturer's recommendation for material being cut. |
| * | Check for suitability of cutting dry. |
| * | Inspect diamond blade for damage before mounting on saw. |
| * | Inspect arbor shaft and mounting flanges for damage or uneven wear and they are of equal or
correct diameter. |
| * | Be sure blade is mounted on correct diameter shaft with arrow in the proper direction of rotation
and blade shaft nut is securely tightened with wrench. |
| * | Check for continuous flow of water to both sides of the blade in case of wet cutting.
* Inspect power tools for proper condition before operating. |
| * | Inspect power tools for proper condition before operating. |
| * | Inspect blade periodically during use for fatigue cracks, segment damages, and excess wear
under segments. |
| * | Wear proper safety equipments such as safety glasses, safety footwear, snug fitting clothing,
hearing and head protection, and respiratory equipment at all times. |
|
|
|
 |
|
|
| * | Do not operate any saw without safety guards in place and properly secured. |
| * | Do not exceed maximum operating speed established for blade diameter. |
| * | Do not force blades onto machine blade shaft, alter size of mounting hole, or tighten mounting
nut excessively. |
| * | Do not cut long continuous cuts with dry cutting blades : allow blade to cool by turning in air
every few minutes. |
| * | Do not operate saw with blade diameter larger than machines capacity. |
| * | Do not cut dry with blade recommended for wet cutting. |
| * | Do not force blade into material. Allow blade to cut as its own speed. |
| * | Do not cut or grind with side of blade. |
| * | Do not cut a curve or radius. |
| * | Do not stand in direct line with dry diamond or abrasive blades during start-up and operation. |
