GENERAL INFORMATION

INTENDED USE

Operate the SP118 Saw, tools and components in accordance with the manufacturer's instructions. Use of any other tools for stated operation is considered contrary to designated use. The risk of such use lies entirely with the user. The manufacturer cannot be held liable for damages as a result of misuse.

General Information

The MQ SP118 Saws are designed for wet or dry cutting of concrete or asphalt utilizing Diamond Blades. These saws have been engineered for general and industrial flat sawing applications.The reinforced steel box frame design adds strength necessary to reduce blade vibrations while cutting. By minimizing blade vibrations the performance of the blade is enhanced and thus the life of the blade is extended.

Heavy-duty front and rear axles, sturdy oversized wheels, and industrial undercarriage assembly ensure accurate tracking and years of reliable use.

Additionally, the general strength-to-weight ratio design of the frame and chassis assembly provides for optimum weight distribution to keep the blade running true in the cut. A rugged spindle bearing assembly ensures minimal flutter and shaft harmonics providing the most advantageous condition for a diamond blade at operating speeds.

This saw comes equipped with an 18-inch blade guard and handles Diamond Blades ranging in size from 12-18-inches in diameter.

Power Plants

The SP118 saw is generally considered a "low" powered saw in the industry. This classification is particularly useful when selecting the proper diamond blade for an application.

This SP118 saw is powered by a HONDA GX390U1QWT2 air cooled, 4-stroke, single cylnder, OHV gasoline engine rated at 11 HP (8.2 kW) at 3,600 RPM.

Refer to the HONDA Engine Owner's Manual for specific information regarding engine operation and maintenance procedures.

BLADE ROTATION

Three premium 3VX belts connecting a properly sized drive (engine) pulley and an output blade shaft pulley provides the rotational power of the diamond blade. Specific pulley diameters have been chosen to support the design of the SP118 saw.

Ultimate blade shaft RPM speed is very important for the safe, efficient operation of the diamond blade in the cut.

All SP118 SAWS are designed, engineered and manufactured with strict adherence to American National Standards Institute, Inc. (ANSI) guidelines B7.1 and B7.5.
