FS2 CONCRETE SAW — GENERAL INFORMATION
UNDER CARRIAGE SYSTEM
A jig welded heavy steel gauge under carriage assembly supports the saw in tracking, pivoting and stabilization. A 3/4" diameter rear axle supports two solid rubber (10" x 2.75" x 3/4") cast hub wheels with roller bearings, grease fittings and locking collars. A 5/8" diameter front axle supports two solid rubber (5" x 2" x 5/8") cast hub wheels with roller bearings, grease fittings and locking collars. The assembly pivots about the rear axle and is lubricated through a
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 respect shafts via taper lock bushings, and three 3VX
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 38.
BLADE GUARD ASSEMBLY
The
The sizable (6") fluted tubes that direct the floodwater resist clogging and are easily removed for maintenance. Second, a true water misting manifold assembly provides specifically oriented cones of aerosol spray to the blade via two water jet nozzles.
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.
The blade guard is removable for quick 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 48 and 50.
WATER SYSTEM
The FS2 Series employs an independent water system that provides either floodwater or aerosol misting water to the blade. For floodwater, two 6" fluted tubes are connected via a manifold, and are oriented inside the blade guard to provide optimum water volume and dispersal to both sides of the blade.
A separate water misting system (14" blade guard) utilizes specifically positioned spray nozzles that project a special cone of aerosol water to the blade when dry cutting and/or cutting operations that require minimal usage of water. This misting spray (approximately 5 gallons/hour), along with the geometry of the blade guard considerably diminish the dust signature generated by dry cutting. The water misting system requires approximately 40 psi of pressure for effective results.
A standard "garden hose" hookup valve connects the water source to the saw, and a
CONSOLE
An ergonomically designed control console allows the operator to easily understand and/or operate the depth feed gauge, positive 3- way water valve, raise/lower control handle, digital engine tachometer/hourmeter, engine ON/OFF switch, handle bar assembly, and standard "garden hose" water hook up. A rear panel cover assembly is easily removed to permit access inside the console of the saw. See page 44.
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
A steel pointer assembly is synchronized with raise/lower handle rotations to accurately depict depth feed. See Table 4 for blade selection with respect to depth of cut. Blade orientation is referenced on the console's horizontal depth feed gauge (see page 52), and is calibrated for 12", 14", 16" and 18" diamond blades.
