FS2/FS2SP CONCRETE SAW — GENERAL INFORMATION  
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 (14" blade guard only) to diminish material  
dust cutting in situations where minimal water usage is necessary.  
Quick disconnect hose fittings are provided for quick and easy water  
orientation.  
FAMILIARIZATION  
The MQ Whiteman FS2/FS2SP 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.  
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/OFFWaterValve, 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.  
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  
minimalflutterandshaftharmonicsprovidingthemostadvantageous  
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.  
All MQWhiteman FS2/FS2SP 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/FS2SP 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 positive locking Raise/Lower screw feed system with accurate  
depth gauge easily orients blade elevation, and will not permit blade  
creep during cutting operations.  
TheFS2/FS2SP seriessaws aregenerallyclassifiedintheindustry  
as a "LOW to MEDIUM " horsepower saws. This classification is  
particularly useful 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.

FS2/FS2SP CONCRETE SAW — GENERAL INFORMATION  
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 54 and 56.  
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 (8" x 2-1/2" x 1") cast hub wheels with  
roller bearings, grease fittings and locking collars. A 3/4" diameter  
front axle supports two solid rubber (5" x 2" x 3/4") cast hub wheels  
with roller bearings, grease fittings and locking collars. The assembly  
pivots about two rocker blocks with bushings. See page 40.  
WATER SYSTEM  
All FS2 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 either a 14" or 20" blade guard.  
BLADE DRIVE SYSTEM  
Both the 14" and 20" blade guards are designed with two 6" fluted  
water tubes to direct floodwater to the diamond blade.The 14" blade  
guardincorporatesanindependentwatermistingsystemthatutilizes  
specifically positioned aerosol spray nozzles to support dust  
suppression when sawing in minimal water environments.  
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 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 misting spray (approximately 5 gallons/hour) requires a 35-45  
psi water pressure for effective results.  
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.  
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 44.  
MECHANICAL RAISE/LOWER SYSTEM  
BLADE GUARD ASSEMBLY  
A positive locking mechanical raise and lower screw feed assembly  
supports elevation cycling operations. A crank raise/lower handle  
islocatedontheconsolewith"clockwise"rotationprovidinglowering  
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.  
The FS2/FS2SP comes standard with either a 14" or 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.  
An adjustable depth gauge assembly is synchronized with raise/  
lower handle rotations to accurately depict depth feed.SeeTable 4  
for blade selection with respect to depth of cut. Blade orientation is  
referenced on the console's depth feed gauge.  
The spray pattern and orientation, in conjunction with the design of  
thebladeguard, providesexceptionaldustsuppressionwhencutting  
dry, and may also be desired when the job site requires minimal use  
ofwater.  
TABLE 4. BLADE SELECTION  
The 14" blade guard is designed with an independent aerosol  
misting system to meet the challenges of minimal water sawing  
operations.The spray pattern and orientation of the two removable

FS2/FS2SP CONCRETE SAW — INSPECTION -BLADE  
4.  
Directional Arrow – Check to ensure that the blade is  
oriented properly on the blade shaft for sawing. Reference  
the directional arrow in the blade and place it so the direction  
of rotation “downcuts” with the turn of the shaft.  
WARNING  
Failure to thoroughly inspect the diamond blade (Figure 12) for  
operational safety could result in damage to the blade, the saw,  
and may cause injury to the user or others in the operating area.  
5.  
Diamond Segment or Rim – Ensure there are no cracks,  
dings, or missing portions of the diamond segment/rim. DO  
NOT use a blade that is missing a segment or a portion  
of the rim. Damaged and/or missing segments/rims may  
cause damage to your saw, and injury to the user or others  
in the operating area.  
6.  
7.  
Specifications – Ensure that the blade specifications, size,  
and diameter properly match up to the sawing operation.  
Wet blades must have water to act as a coolant. Utilizing a  
diamond blade not matched properly to the task may result  
in poor performance and/or blade damage.  
Arbor Hole – It is essential that the arbor hole diameter  
properly matches the blade, and that it is free from  
distortions. Correct blade flanges (collars) must be used.  
The inside face of the flanges must be clean & free of debris.  
An out of round arbor condition will cause damage to the  
blade and the saw.  
8.  
MAX RPM – This RPM reference is the maximum safe  
operating speed for the blade selected. NEVER exceed  
the max RPM on the diamond blade. Exceeding the MAX  
RPM is dangerous, and may cause poor performance and  
may damage the blade.  
Figure 12. Diamond Blade  
1. Drive Pin Hole – A commonly located hole on the diamond  
blade core that prevents operational blade slippage  
between the inner & outer blade flanges (collars). Inspect  
the diameter of the hole to ensure there is no distortion,  
and that a snug fit develops between the hole and drive  
pin.  
2.  
Stress Relief Holes (Gullets) – Check the steel core for  
cracks that may have propagated from the slots and/or  
gullets. Cracks indicate extreme fatigue failure and if sawing  
continues, catastrophic failure will occur.  
3.  
Edge Of The Steel Core – Check the diameter edge for  
discoloration (blue oxidation) indicating an overheating  
condition caused by insufficient cooling water/air.  
Overheating of blades may lead to loss of core tension  
and/or increase the possibility for blade failure. Check to  
make sure the steel core’s width is uniform about the rim of  
the blade, and not succumbing to an “under cutting”  
condition brought about by highly abrasive material or  
improper under cutting core protection.

FS2/FS2SP CONCRETE SAW — OPERATION  
Saw Alignment  
CAUTION:  
1. The FS2/FS2SP employs a front and rear pointer (Figure 25)  
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.  
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.  
6. Slowlylowerthediamondbladeontothecutlinebycranking  
theRaise/Lowerhandleclockwise. Whentheblade“touches”

5,item12)byrollingthedepthwheeluntil“0”islinedupwith  
theslipmark. Slowlycontinuetolowerthebladeintothecut  
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  
specificationsrequire. Deepsawingiswastefultothelifeof  
the blade. The preferred method of sawing is to “step cut”  
in increments of 2” (51 mm). Step cutting provides the  
optimum opportunity for the blade to cut fast and last it’s  
longest.

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  
For Misting Water Sawing:  
WARNING  
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(14" blade guard only).  
The operator must wear the appropriate protective  
equipment and clothing while engaged in sawing.  
For wet sawing :  
1. Ensure the proper DRY CUTTING Diamond Blade is se-

UndercarriageAssembly.  
2. RearWheels (2):Grease daily, see page 44, item10, Rear  
AxileAssembly.  
WARNING  
3. Blade Shaft Bearings (2): Grease daily, see page 46,  
item1, Blade Shaft Assembly.  
Some maintenance operations may require  
the engine to be run. Ensure that the mainte-  
nance area is well ventilated. Exhaust contains poisonous car-  
bon monoxide gas that can cause of unconsciousness and may  
result in DEATH.  
4. Raise/Lower AdjustTube (1): Grease daily, see page 60,  
item26, Raise/LowerAssembly.  
5. Transmission Shaft Bearings (2): Grease weekly/or 25
