3.
Abrasive blades must have mounting blotters on both sides and be speed tested per ANSI B7.1 Safety Code
specifications. DESTROY THE BLADE IF IT DOES NOT MEET ANSI B7.1 SPECIFICATIONS. Make sure the
blotters are in good condition between the blade and flanges. The cushion provided by the blotters protects the blade
from uneven strain.
4.
Remove the drive screw from arbor flange when using an abrasive blade. Install the blade on the arbor shaft. Make
sure a blade is installed correctly to the rotation of the saw. Saw rotation is clockwise as viewed from the arbor nut
side of the saw.
CAUTION:
DO NOT FORCE A BLADE ONTO THE ARBOR FLANGE OR USE A BLADE THAT FITS THE
ARBOR TOO LOOSELY. NEVER ALTER THE SIZE OF THE ARBOR HOLE. THE BLADE
MUST FIT THE ARBOR FLANGE PROPERLY.
5.
Inspect the flange for gouges, warps, nicks, hairline cracks, wear, dirt, or sprung condition. Replace the flange
immediately if any of these conditions are present. Install the flange on the arbor shaft.
6.
For blades that require a drive screw, insure the screw #55 is installed in the flange to prevent blade slippage
between the two flanges.
7.
Thread the arbor nut counter-clockwise on the arbor shaft. Tighten using the provided arbor wrench. Be sure the
flanges are tightened securely, but not excessively. Excessive tightening will spring the flanges and change the
pressure area.
8.
Tighten the five blade guard screws to secure the blade guard.
NEVER
operate the saw without the guard in place.

Remove the blade from the arbor shaft as described in Section 4.3.1.
2.
Loosen the set screw that secures the arbor flange to the motor shaft.
3.
Insure bolt on arbor removal tool is threaded out to its outer-most position. Thread arbor removal tool counter-
clockwise onto arbor shaft. Screw arbor removal tool bolt clockwise to pull arbor flange off motor shaft.
4.4.2
Arbor Flange Installation
1.
Insure the arbor flange fits snugly on the motor shaft. Then remove the arbor flange from the motor shaft.
2.
Apply Loctite RC609 or equivalent on the motor shaft. Follow the manufacturer’s instructions for curing. Install the
arbor flange on the motor shaft.
