FS3SP CONCRETE SAW — GENERAL INFORMATION

FAMILIARIZATION

The MQ Whiteman FS3SP Series concrete saws are designed for wet or dry cutting utilizing diamond blades. They are self-propelled via a hydrostatic transmission system and have been engineered for general, industrial and high production flat sawing applications. The exceptional performance of these saws centers around innovative features, top quality components, and committed attention to state-of-the-art manufacturing.

The reinforced heavy gauge steel frame and chassis assembly has been precisely jig welded to eliminate operational bending and/or flex that would lead to diminished blade performance. Additionally, the general weight-to-strength ratio design of the frame and chassis assembly provides for optimum weight distribution to keep the blade running true in the cut.

An innovative outboard blade shaft bearing assembly ensures minimal flutter and shaft harmonics providing the most advantageous condition for a diamond blade at operating speeds. Also, this design further promotes greater operating life to the blade shaft bearings and V-Belts.

Heavy duty front and rear axles, oversized reinforced wheels supported by roller wheel bearings and locking collars, and industrial under carriage assemly ensure accurate tracking and years of reliable use. The positive locking Raise/Lower screw feed system with accurate depth gauge easily orients blade elevation, and will not permit blade creep during cutting operations.

Operator control of the saw is safely accomplished with adjustable ergonomic handle bars, and a combination of conveniently oriented items on the console such as: Raise/Lower Crank Handle, Tachometer/Hourmeter, ON/OFF Water Valve, Depth Feed Gauge, and Emergency Engine ON/OFF switch. Additionally, the console also provides starting, power control and forward/reverse controls.

All MQ Whiteman FS3SP saws are designed, engineered and manufactured with strict adherence to American National Standards Institute, Inc. (ANSI) guidelines B7.1 and B7.5.

POWER PLANTS

The FS3SP Series saws provides a variety of gasoline engine choices (Table 3). Selection of a specific engine, and its capacity measured in horsepower/torque, directly affects the performance of the diamond blade.

The FS3SP series saws are generally classified in the industry as

UNDER CARRIAGE SYSTEM

A jig welded heavy steel gauge under carriage assembly supports the saw in tracking, pivoting and stabilization. A 1" diameter rear axle supports two solid rubber (10" x 2.75") cast hub wheels with roller bearings, grease fittings and locking collars. A 5/8" diameter front axle supports two solid rubber (5" x 2") cast hub wheels with

WATER SYSTEM

All FS3 saws provide a water direction system to provide cooling water to the diamond blade. This system consist of : a standard "garden hose" valve that connects the water source (via hose) to the saw, an ON/OFF console water switch, water hose with quick disconnect manifold fittings, and a 14" or 20" blade guard.

roller bearings, grease fittings and locking collars. The assembly pivots about two rocker blocks with bushings. See page 42.

CONSOLE

BLADE DRIVE SYSTEM

An innovative 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, and four 3VX V-belts connect the engine pulley to the blade shaft pulley. The 1- 1/4" diameter 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. The blade drive system has been designed for left and right hand cutting. See page 46.

An ergonomically designed control console allows the operator to easily understand and/or operate the adjustable handlebars, Raise/ Lower Crank Handle, Tachometer/Hourmeter, ON/OFF Water Valve, Depth Feed Gauge, and Emergency Engine ON/OFF Switch. Additionally, for electric start and self-propelled models, the console also provides starting, power control and forward/reverse controls.

MECHANICAL RAISE/LOWER SYSTEM

A positive locking mechanical raise and lower screw feed assembly supports elevation cycling operations. A crank raise/lower handle is located on the console with "clockwise" rotation providing lowering action, and "counter-clockwise" rotation providing raising action. An ACME precision screw and thread assembly provide accurate travel; while a spring loaded plunge ball system ensures positive height position locking.

An adjustable depth gauge assembly is synchronized with raise/ lower handle rotations to accurately depict depth feed. See Table 4

BLADE GUARD ASSEMBLY

for blade selection with respect to depth of cut. Blade orientation is referenced on the console's depth feed gauge.

The FS3SP offers a 14" or a 20" hinged two-piece, heavy steel gauge blade guard.

Both blade guards provide zinc plated, fluted floodwater manifold assemblies that supply optimum volume and dispersal of water to both sides of the diamond blade for wet cutting. The sizable (6") fluted floodwater tubes resist clogging and are easily removed for maintenance.

The spray pattern and orientation, in conjunction with the design of the blade guard, provides exceptional dust suppression when cutting dry, and may also be desired when the job site requires minimal use of water.

A quick disconnect hose and blade guard are easily removed for fast blade changes, and easily seats itself on the chassis bayonet fitting. The blade guard may be oriented for left or right hand cutting. See pages 56.

6. Specifications – Ensure that the blade specifications, size,

and diameter properly match up to the sawing operation. Wet blades must have water to act as a coolant. Utilizing a diamond blade not matched properly to the task may result in poor performance and/or blade damage.

7. Arbor Hole – It is essential that the arbor hole diameter

properly matches the blade, and that it is free from distortions. Correct blade flanges (collars) must be used. The inside face of the flanges must be clean & free of debris. An out of round arbor condition will cause damage to the blade and the saw.
