FS2 CONCRETE SAW — INSPECTION -BLADE

WARNING

Failure to thoroughly inspect the diamond blade (Figure 9) for operational safety could result in damage to the blade, the saw, and may cause injury to the user or others in the operating area.

Figure 9. Diamond Blade

1. Drive Pin Hole – A commonly located hole located 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 blade shaft for sawing. Reference the directional arrow in 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 blade, 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.
