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

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.

Stopping the Engine
NEVER stop the engine while the blade is in the cut, except for
extreme emergencies. A sudden stoppage of the engine at high
speed while in a cut could damage the blade and/or saw, and
may cause injury to the user or other in the operating area.

The FS3SP employs a front and rear pointer (Figure 24) that
has been precisely aligned with the diamond blade at the
factory. Referencing the figure below, accurate tracking is
accomplished by referencing the front and rear pointer tips
over the cut line. Precise saw direction is accomplished by
slight operator pressure against the handle bars.
Figure 24. Saw Pointers (Front/Rear)

To reorient a pointer position, loosen the screw that secures
the pointer bar to the shaft, adjust as necessary, and retighten
the screw.
3.For operator comfort, ergonomically designed handle bars
adjust by loosening two clamping knobs (Figure 5, item 14),
and adjusts to the desired height. Tighten the knobs back
down when the desired height has been achieved.
Wet Saw Operation
CAUTION:
6.Slowly lower the diamond blade onto the cut line by cranking
the Raise/Lower handle clockwise. When the blade “touches”
the cutting surface, “zero-out” the depth feed gauge (Figure
5, item 10) by rolling the depth wheel until “0” is lined up with
the slip mark. Slowly continue to lower the blade into the cut
until the desired depth is achieved.
If the water supply to your blade is interrupted - STOP
sawing immediately.
7.Set the sawing depth and saw only as job conditions and
specifications require. Deep sawing is wasteful to the life of
the blade. The preferred method of sawing is to “
in increments of 2” (51 mm). Step cutting provides the
optimum opportunity for the blade to cut fast and last it’s
longest.

WARNING
The operator must wear the appropriate protective

psi.
2.Ensure the quick disconnect water those fitting is connected
to the Floodwater manifold of the blade guard.
3.Turn water source on.
4.Select the “ON” position (water valve on the saw console),
and ensure the proper flow and rate (4-6 gallons/minute) is
equally directed to both sides of the diamond blade.
5.Align the saw along the cut line utilizing the front and rear
pointers.
If the engine stalls for any reason during
sawing, raise the blade out of the cut
