BLADEs

4.Outside Blade Flange (Collar) — Ensure that the outside blade flange is placed flush against the diamond blade. The inside surface of the flange must be free of debris and permit a tight closure on the surface of the blade core.

5.Diamond Blade — Ensure that the proper diamond blade has been selected for the job. Pay close attention to the directional arrows on the blade. The blade's operating directional arrows must point in a "down- cutting" direction to perform correctly. When placing the blade onto the spindle, ensure the arbor hole of the blade matches the diameter of the shaft.

6.Inner Flange (Collar) — This flange is fixed upon the spindle. The inside surface of the flange must be free of debris and permit a tight closure on the surface of the blade.
