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 90-degree
grease fitting in the rear axle tube. See page 36.
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 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 38.
BLADE GUARD ASSEMBLY
The two-piece heavy gauge blade guard, available in 14" or 18".
The 14" blade guard (standard) is designed with two fully
independent water systems to meet the challenges of dry or wet
cutting operations. First, a fluted floodwater manifold assembly
supplies optimum volume and dispersal of water to both sides of the
diamond blade for wet cutting applications.
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 3-way water lever (OFF/MIST/FLOOD) is
conveniently located on the console. See page 44.
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 "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.
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.
