the diamond blade (7). Check that the drive pin goes through
the blade pin hole (6) and seats properly into the inner
flange (8).
5. Blade Pin Hole – Align this hole with the drive pin hole on
the inner flange collar.

cutting. The arbor hole
of the blade must match the 1" arbor of the blade shaft.
7. Inner Flange Collar – This flange is fixed upon the blade
shaft, and is manufactured with a drive pin hole. The inside
surface of the flange must be free of debris and permit a
tight closure on the surface of the blade.
