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
roller bearings, grease fittings and locking collars. The assembly
pivots about two rocker blocks with bushings. See page 42.
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.
BLADE GUARD ASSEMBLY
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.
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.
CONSOLE
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
for blade selection with respect to depth of cut. Blade orientation is
referenced on the console's depth feed gauge.
