ASSEMBLY INSTRUCTIONS/OPERATIONS
FIGURE 25
The amount and direction of forces to apply to the operator handle are governed by, but not necessarily limited to the following factors:
a)Average Random Crack Width.
b)Diamond Blade Saw Width.
c)Sawing Depth.
d)Tensile strength of the material being sawed.
e)Matrix material of the diamond blade segments in consideration of the aggregate type, amount and/or hardness contained in the material being sawed.
f)Service condition of the diamond blade segments.
g)Operating RPM speed range for the diamond blade.
9)For normal job applications, operate the engine at a maximum, governed speed of 3450 RPM. Consult the material supplied by the engine manufacturer and the Specifications section for specific information. If you have any questions regarding specific job applications, contact the Customer Service Department for information. There is no charge for this service. Additional information can be obtained from the Masonry and Concrete Saw Manufacturers Institute, 30200 Detroit Road, Cleveland, OH

10)The wide variety of potential work surface materials along with the corresponding variety of job site environments, make it impossible to develop a standardized operating procedure for the Crack Saw. Use of the Crack Saw will require constant trial and error testing until satisfactory results are achieved. Experience gained over time and common sense will help minimize the amount of necessary testing. Many factors will directly affect the operating parameters and/or techniques utilized for a specialized job application. Some of these factors include:
a)Work surface material yield and tensile values. As a general rule, these values will determine material removal rate per unit of time. Materials with high yield and tensile values will characteristically resist/limit material penetration. For such materials, the accepted procedure is to make a number of multiple passes over the work surface rather than attempt to make a single, deep pass. The net effect is to actually increase productivity: more material removed in less time. Other added benefits to this technique are decreased vibration, less operator fatigue and increased component service life.
b)The width of the random crack in comparison to the required cutting width and depth. For example, if the random crack has an average width of 1/8 inch, productivity rates will be greater with the use of a 1/4 inch wide blade over that delivered by a 1/2 inch wide blade. The same analogy can also be used for the cutting depth. Productivity rates will be greater for a 1/2 inch deep cut than a
