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.

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.
