STOW CUTTER 1 CE SAW— BLADES
SPECIFICTOOLSTO BE USED
This saw is to use tools (blades) as follows:
Steel Core Segmented or Continuous Diamond Rim Cutting Wheel.
Any other type of tool is not to be used. See Table 4 for specific blade usage for material.
WARNING
Failure to thoroughly inspect the diamond blade (Figure 10) for operational safety could result in damage to the blade or the saw, and may cause injury to the user or others in the operating area. Discard damaged or worn blades and replace with fresh blade.
Figure 10. Diamond Blade
1. | Drive Pin Hole – A commonly located hole on the diamond |
| blade core that prevents operational blade slippage |
| between the inner & outer blade flanges (collars). Inspect |
| the diameter of the hole to ensure there is no distortion, |
| and that a snug fit develops between the hole and drive |
| pin. |
2. | Stress Relief Holes (Gullets) – Check the steel core for |
| cracks that may have propagated from the slots and/or |
| gullets. Cracks indicate extreme fatigue failure and if sawing |
| continues, catastrophic failure will occur. |
3. | Edge Of The Steel Core – Check the diameter edge for |
| discoloration (blue oxidation) indicating an overheating |
| condition caused by insufficient cooling water/air. |
| Overheating of blades may lead to loss of core tension |
| and/or increase the possibility for blade failure. Check to |
| make sure the steel core’s width is uniform about the rim of |
| the blade, and not succumbing to an “under cutting” |
| condition brought about by highly abrasive material or |
| improper under cutting core protection. |
4. Directional Arrow – Check to ensure that the blade is oriented properly on the spindle for sawing. Reference the directional arrow on the blade and place it so the direction
| of rotation “downcuts” with the turn of the shaft. |
5. | Diamond Segment or Rim – Ensure there are no cracks, |
| dings, or missing portions of the diamond segment/rim. DO |
| NOT use a blade that is missing a segment or a portion |
| of the rim. Damaged and/or missing segments/rims may |
| cause damage to your saw, and injury to the user or others |
| in the operating area. |
6. | Specifications – Ensure that the blade specifications, size, |
| and diameter properly match up to the sawing operation. |
| Wet blades must have water to act as a coolant. Utilizing a |
| diamond blade not matched properly to the task may result |
| in poor performance and/or blade damage. |
7. | Arbor Hole – It is essential that the arbor hole diameter |
| properly matches the shaft arbor, and that it is free from |
| distortions. Correct blade flanges (collars) must be used. |
| The inside face of the flanges must be clean & free of debris. |
| An out of round arbor condition will cause damage to the |
| blade and the saw. |
8. MAX RPM – This RPM reference is the maximum safe operating speed for the blade selected. NEVER exceed the max RPM on the diamond blade. Exceeding the MAX RPM is dangerous, and may cause poor performance and may damage the blade. All blades used must be designed for the maximum spindle RPM.
