Blades
WARNING
Failure to thoroughly inspect the blade for operational safety could result in damage to the blades or the saw and may cause serious injury to the user or others in the operating area. Inspect the blade flanges and shaft for damage before installing the blade.
Blade Components
Diamond blades are recommended for your saw. Ask your Multiquip dealer about your specific cutting application. Figure 8 highlights the components of a diamond blade.

1.Stress Relief Holes (Gullets) — Check the steel core for cracks that may have propagated from the slots and/or gullets. Cracks indicate extreme fatigue failure and if sawing continues, catastrophic failure will occur.
2.Edge of the Steel Core — Check the diameter edge for discoloration (blue oxidation) indicating an overheating condition caused by insufficient cooling water/air. Overheating of blades may lead to loss of core tension and/or increase the possibility for blade failure. Check to make sure the steel core’s width is uniform about the rim of the blade, and not succumbing to an “under cutting” condition brought about by highly abrasive material or improper under cutting core protection.
3.Directional Arrow — Check to ensure that the blade is oriented properly on the spindle for sawing.Reference the directional arrow on the blade and place it so the direction of rotation “downcuts” with the turn of the shaft.
4.Diamond Segment or Rim — Ensure that there are no cracks, dings, or missing portions of the diamond segment/rim. DO NOT use a blade that is missing a segment or a portion of the rim. Damaged and/or missing segments/rims may cause damage to your saw and injury to the user or others in the operating area.
5.Specifications — Ensure that the blade specifications, size, and diameter properly match up to the sawing operation.Wet blades must have water to act as a coolant. Utilizing a diamond blade not matched properly to the task may result in poor performance and/or blade damage.
6.Arbor Hole — It is essential that the arbor hole diameter properly matches the shaft arbor, and that it is free from distortions. Correct blade flanges (collars) must be used. The inside face of the flanges must be clean and free of debris. An out of round arbor condition will cause damage to the blade and the saw.
7.MAX RPM — This RPM reference is the maximum safe operating speed for the blade selected. NEVER exceed the max RPM on the diamond blade.Exceeding the MAX RPM is dangerous, and may cause poor performance and may damage the blade. All blades used must be designed for the maximum spindle RPM.
Cutting Depth
The recommended cutting depth is 1/4" (6 mm) below the cutting table surface. To adjust the cutting depth, loosen the cutting head adjustment knob so that the blade is 1/4" below the top of the cutting table's surface.See Table 4 to determine cutting depth by blade diameter.
WARNING
Setting the blade too low may damage the cutting table and if set too high, the blade may grab the material being cut, causing damage and possibly injury.
