PRE-SETUP (ELECTRIC)

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.

SAW BLADES

Diamond Blades ™ are recommended for you saw. Ask your MULTIQUIP dealer about your specific cutting application.

SAW BLADE DEFINITIONS (FIGURE 8)

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.

Figure 8. Diamond Blade

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. 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 - Ensure that the blade is oriented properly on the blade shaft 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 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 or injury to the user or others in the operating area.

5.Specifications - Ensure that the blade specifications, size, and diameter properly match up to sawing operations. Utilizing a 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 blade, and that it is free from distortion. 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 maximum RPM is dangerous and may cause poor performance and may damage the blade.

BLADE INSTALLATION

1. Use the blade nut wrench (Figure 9) supplied with the saw to install the cutting blade.

2.Ensure the capacity of the blade guard matches the diameter of your cutting blade.

3. Using the blade nut wrench, remove the bladeshaftnut and outsidebladeflange. Installthecuttingbladeontothe inside blade flange arbor. Re-install the outside blade flange and blade shaft nut. Tighten securely. DO NOT over tighten.
