PREPARATION / PRE-INSPECTION

1.Read and fully understand this manual, the safety instructions in particular, and the engine manufacturer's manual supplied with the saw.

2.Select the correct blade for each application. If abrasive blades are used, MAKE CERTAIN they are designed for use on a concrete floor saw. They must be reinforced and have a hole for the driving pin. When wet cutting with an abrasive blade, MAKE CERTAIN the blade is intended for wet cutting. Water will destroy a dry cut abrasive blade. Some diamond blades require water cooling and failure to do so will destroy them almost immediately. Other diamond blades can be used with or without water.

3.Handle all blades with care and NEVER use a damaged blade. NEVER use an abrasive blade that has been dropped.

BLADES

Saw blades, or cutting disks, are available in either an abrasive design or as diamond blades. Either blade will work on the HS62CUT-OFFSAW,however,diamondbladesare recommended. Ask your dealer about your specific cutting application.

SAW BLADE INSPECTION

WARNING

Failure to thoroughly inspect the diamond blade (Figure 24) for operational safety could result in damage to the blades or the saw and may cause injury to the user or others in the operating area.

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. 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.
