BLADES
BLADE PLACEMENT
1. Blade Guard — Pivot the blade guard front cover all
the way back. The guard tension spring will keep the
front cover in position.
2. Blade Hex Nut — Unscrew the blade shaft nut (right
side loosens clockwise and tightens counter-clockwise
while the left side loosens counter-clockwise and
tightens clockwise. DO NOT overtighten the nut
(approximately 45-50 ft. lb/61-68 N/m) when finalizing
the assembly.
3. 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.
4. 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 blade shaft, ensure the arbor hole
of the blade matches the diameter of the shaft.
5. Inner Flange (Collar) — This flange is fixed upon the
blade shaft. The inside surface of the flange must be
free of debris and permit a tight closure on the surface
of the blade.
BLADE SPEED
A diamond blade’s performance is directly connected to
specific peripheral (rim) speeds.
The following shaft rotational speeds have been factory set
to ensure optimum blade performance.

lb/61-68 N/m) when finalizing the assembly.
CAUTION
ALWAYS ensure that unit is unplugged (disconnected)
when installing blade.
