The MQ Whiteman FS2 Series Concrete Saws are designed for
wet or dry cutting utilizing diamond blades. They 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. Heavy duty
front and rear axles, oversized reinforced wheels supported by roller
wheel bearings and locking collars, and industrial under carriage
assembly 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.
A unique water plumbing system allows for independent orientation
of either fluted floodwater to the blade for wet cutting applications or
cones of aerosol mist to diminish material dust when dry cutting.
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 Handle, Tachometer/
Hourmeter, 3-way water valve, depth feed gauge, and engine ON/
OFF switch.
All FS2 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 FS2 Saw Series 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 FS2 series is generally classified in the industry as a "
MEDIUM
when selecting the proper diamond blade for an application. Refer
to the engine Owner's Manual for specific instructions regarding
engine operation and maintenance practices.
LOW
to
" horsepower saw. This classification is particularly useful
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.
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
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.
(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 3way 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
CCC
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.
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.
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.
A self-powered digital Tachometer/Hourmeter keeps true
running RPM and time. The operation is triggered by an external
lead wrapped around the spark plug of the engine. When the
engine is running, the display will read the RPM of the engine.
When the engine is off, the display will switch to run time (initially
in minutes), and then switching to hours after the first hour of
operation. This instrument provides quartz crystal solid-state
technology, and is built with a custom chip and die bonding
construction for maximum durability.
Figure 6 shows the location of the components of the FS2
Console. The function of each component is described below:
1.Horizontal Depth Feed Gauge – Indicates the blade
cutting depth in inches. The scale allows for orientation of
12, 14, 16 and 18 inch diamond blades.
Depending on the blade diameter selected, the steel
pointer head will indicate zero inches when the blade is
just touching the surface, positive numbers when below
the surface, and negative numbers when above the surface.
The "Depth Feed Gauge" is calibrated in inches and is set
at the factory

The FS2 employs a front and rear pointer (Figure 22) 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.

To reorient a pointer position, loosen the hex screw that
secures the pointer bar to the shaft, adjust as necessary, and
retighten the hex screw.
5.Set the depth and saw only as the job conditions and
specifications require. Unnecessary deep sawing is wasteful
to the life of your blade.
6.The preferred method of sawing is to step cut in increments
of 2” (51mm). “Step-cutting” provides the optimum opportunity for the blade to cut fast and last its longest.
CAUTION:CAUTION:
CAUTION:
CAUTION:CAUTION:
ALWAYS saw in a straight line only. Serious
damage to the blade may occur if the saw is
twisted or forced to cut radius shapes.
7.The rotation of the blade creates a tendency for the saw to pull
in a particular direction (to the right if the blade is mounted on
the right, to the left if the blade is mounted on the left).
8.To ensure a straight line of sawing, apply pressure to the
appropriate handle as you slowly advance the saw forward.
DO NOT force the blade to the cut any faster than its natural
tendency.
3.For operator comfort, an ergonomically designed handle bar
adjusts by loosening two clamping knobs (page 46, item 8),
and adjusts to the desired height. Tighten the knobs back
down when the desired height is met.
Wet Saw Operation
WARNING
The operator must wear the appropriate protective equipment
and clothing while engaged in sawing.
1.Connect hose from water source to the hose fitting connec-
tion (see item 14, page 44 "Water System Assembly") on the
saw. The source pressure should be approximately 40 psi.
If the engine stalls for any reason during
sawing, raise the blade out of the cut
before restarting.
9.The operator must recognize and adhere to the optimum
speed that the saw advances while sawing. DO NOT

The operator must wear the appropriate protective equipment
and clothing while engaged in sawing.
1.Ensure the proper DRY Cutting blade is selected for the job.
2.With the 14" blade guard, select the “MIST” position (misting
water) or the “OFF” position on the console (Figure 6). If
misting water is desired, the water source must be able to
deliver 40 psi of pressure to ensure an optimum spray
pattern.
3.The Water Misting system is designed to suppress the dust
signature caused by dry sawing. The aerosol spray pattern
and blade guard design greatly diminish the amount of dust
that is created. The misting water also acts as an added
coolant for the blade.
4.The preferred method of sawing is to step cut in increments
of 2” (51mm). “ Step-cutting” provides the optimum opportunity for the blade to cut fast and last its longest. Airflow acts
as a blade coolant during sawing. Cutting too deep with one
pass, or exerting excessive forward/sideward pressure may
damage the blade.
Finishing a Cut

Diamond Sawing consists of cutting WET or DRY.
2.Matching the correct blade for the specific job and material
being cut optimizes performance and value.
