STOW CUTTER 3 CE SAW — GENERAL INFORMATION

Familiarization

The Cutter 3 saws are designed for wet or dry cutting of concrete or asphalt utilizing diamond blades.They have been engineered for general, industrial and high production flat cutting applications.The reinforced steel box frame design adds strength necessary to reduce vibrations while cutting. Minimizing vibrations enhances the performance of the blade and extends the life of the saw.

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

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

Power Plants

The Cutter 3 saws are generally classified in the industry as LOW to MEDIUM horsepower saws. This classification is particularly useful when selecting the proper diamond blade for an application.

There are two gasoline engines used with the Cutter 3 saws: A

13HP Honda GX390K1QWT2 air-cooled, 4-stroke single cylinder, OVH rated at 3600 RPM and a 20HP Honda GX620TXF2 air-cooled, 4-stroke OVH 90° V-twin rated at 3600 RPM. Blade rotation is v-belt driven. This is accomplished by connecting to the output shaft of the engine to an upper drive pulley. The lower drive pulley (Blade) is then connected to the upper drive pulley (Engine) by three V-belts. As the engine shaft rotates, so does the blade.

Refer to the engines Owner's Manual for the specific instructions regarding engine operation and maintenance practices.

Console

An ergonomically designed control console allows the operator to easily understand and/or operate the adjustable handlebars, Raise/Lower Crank Handle, and transmission engage/ disengage lever (Self-propelled models only). Additionally, for self-propelled models, the console also provides forward/reverse controls.

Manual Raise/Lower System

The Cutter 3 saw uses an ACME thread, manual raise/lower assembly easily raises and lowers the blade and can lock into position to ensure a constant depth when cutting. See Table 7 for blade selection with respect to depth of cut.

Water System

All saws provide a water direction system to provide cooling water to the diamond blade.This system consists of: a standard "garden hose" valve that connects to the water source (via hose) to the saw, an ON/OFF console water valve'

The 20-inch blade guard is designed with two 6-inch vinyl water tubes to direct water to the diamond blade.

Under Carriage System

A jig welded heavy steel gauge under carriage assembly supports the saw in tracking, pivoting and stabilization. A rear axle supports two solid rubber cast hub wheels with roller bearings, grease fittings and locking collars.A front axle supports two solid rubber cast hub wheels with roller bearings, grease fittings and locking collars.The assembly pivots about two rocker blocks with bushings.

Blade Drive System

A rugged blade shaft assembly has been specifically designed to support the optimum distribution of torque from the engine shaft to the blade shaft, and to ensure minimal vibratory conditions on the tips of the shaft.

Balanced engine & blade shaft pulleys are connected to their respective shafts, 3 V-belts (13HP, 4 V-belts for 20HP models) connect to the engine pulley to the blade shaft pulley.The blade shaft is supported by two self-aligning pillow block bearings that are uniquely positioned on the most outboard portion of the reinforced frame.

The combination of pulley and blade shaft bearing positioning ensures minimal vibration & flutter to the ends of the blade shaft.

Water System

The Stow Cutter 3 Saw comes standard with a 20-inch hinged two piece, heavy steel gauge blade guard. The blade guard provides access for vinyl water tubes that supply optimum volume and dispersal of water for cooling and/or dust suppression.

All Stow Cutter 3 saws are designed, engineered and

NOTEmanufactured with strict adherence to American National Standards Institute, Inc. (ANSI) guidelines B7.1 and B7.5
