vapors can cause an explosion if ignited. DO  
NOT start the engine near spilled fuel or  
combustible fluids. DO NOT fill the fuel tank  
while the engine is running or hot. DO NOT  
overfill tank, since spilled fuel could ignite if it  
comes into contact with hot engine parts or  
sparks from the ignition system. Store fuel in  
approved containers, in well-ventilated areas  
and away from sparks and flames. NEVER  
use fuel as a cleaning agent.

FS3SP CONCRETE SAW — BASIC ENGINE COMPONENTS  
Figure 6. Engine Controls and Components  
WARNING  
INITIAL SERVICING  
The engine (Figure 6) must be checked for proper lubrication and  
filled with fuel prior to operation. Refer to the manufacturers Engine  
manual for instructions & details of operation and servicing.  
Adding fuel to the tank should be accomplished  
only when the engine is stopped and has had an  
opportunity to cool down. In the event of a fuel  
spill, DO NOT attempt to start the engine until the fuel residue  
has been completely wiped up, and the area surrounding the  
engine is dry.  
1.  
Air Filter – A dirty air filter will restrict airflow to the  
carburetor, reducing engine performance.When the engine  
is operated in very dusty conditions, clean the air filter more  
often than specified in the Maintenance Schedule.  
3. Oil Filler Cap –Check the engine oil level with the engine  
stopped and in a level position. Oil is a major factor affecting  
engine performance and service life. Use 4-stroke  
automotive detergent oil.  
NOTE  
Operating the engine without an air filter,  
with a damaged air filter, or a filter in need of  
replacement will allow dirt to enter the  
engine, causing rapid engine wear.  
SAE 10W-30 is recommended for general use. Refer to  
manufacturers Engine Manual for further data regarding  
other viscositiies/temperature limits.  
To Change/Clean Air Filter  
ENGINE OIL REFILL CAPABILITIES:  
■
Remove Air Filter Wing Nut and pull the Air Filter

FS3SP CONCRETE SAW — GENERAL INFORMATION  
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, the console  
also provides starting, power control and forward/reverse controls.  
FAMILIARIZATION  
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  
innovativefeatures, topqualitycomponents, andcommittedattention  
to state-of-the-art manufacturing.  
All MQWhiteman FS3SP saws are designed,engineered and  
manufactured with strict adherence to American National  
Standards Institute, Inc. (ANSI) guidelines B7.1 and B7.5.  
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.  
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.  
An innovative outboard blade shaft bearing assembly ensures  
minimalflutterandshaftharmonicsprovidingthemostadvantageous  
condition for a diamond blade at operating speeds. Also, this design  
further promotes greater operating life to the blade shaft bearings  
andV-Belts.  
The FS3SP series saws are generally classified in the industry as  
a "MEDIUM " horsepower saw. 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.  
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.

FS3SP CONCRETE SAW — GENERAL INFORMATION  
WATER SYSTEM  
UNDER CARRIAGE 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.  
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.  
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.  
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.  
MECHANICAL RAISE/LOWER SYSTEM  
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  
bytwoself-aligningpillowblockbearingsthatareuniquelypositioned  
on the most outboard portion of the reinforced frame.  
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 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 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.  
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  
thebladeguard, providesexceptionaldustsuppressionwhencutting  
dry, and may also be desired when the job site requires minimal use  
ofwater.

FS3SP 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.  
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.  
7.  
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.

3.  
Blade NutWrench – Remove the blade nut wrench (3) fro  
the tool holder and unscrew the blade shaft nut (right-side).  
This nut loosens clockwise and tightens counter-  
clockwise.  
The following steps should be accomplished  
before placing the diamond blade on the  
blade shaft.  
4.  
Blade Nut – Remove the blade nut (4). For reassembly,  
DO NOT over tighten the blade nut against the outer flange.  
Tighten blade nut approximately 45-50 ft-lbs/62-69 N/m.  
5.  
Outside Blade Flange (Collar) – Ensure that the flange  
face is clean and free of debris and is placed flush against  
the diamond blade (7). Check that the drive pin goes through  
the blade pin hole (6) and seats properly into the inner  
flange (8).  
■
■
Place the console ON/OFF button in the OFF position.  
Raise the saw to a high position by cranking the Raise/Lower  
handle in a counterclockwise direction.  
■
Use the Blade Nut Wrench & Blade Shaft Locking Wrench  
stored in the lower section of the console to install the diamond  
blade.  
6.  
Blade Pin Hole – Align this hole with the drive pin hole on  
the inner flange collar.  
7.  
Diamond Blade – Ensure that the proper blade has been  
selected for the job. Pay close attention to the directional  
arrow on the blade, clockwise for right-side cutting,  
counter-clockwise for left-side cutting. The arbor hole  
of the blade must match the 1" arbor of the blade shaft.  
■
Reference Figure 13 (Diamond Blade Placement) when  
removing or installing the diamond blade.  
1.  
Belt Guard – Unscrew the guard security knob and water  
hose quick disconnect fitting and remove blade guard (1)  
from its bayonet fitting and set it beside the saw.  
8.  
Inner Flange Collar – This flange is fixed upon the blade  
shaft, and is manufactured with a drive pin hole.The inside  
surface of the flange must be free of debris and permit a  
tight closure on the surface of the blade.  
2.  
Shaft Lock Tool – Remove the shaft lock tool (2) from  
the tool holder and insert the pointed end through the front  
of the saw frame into the machined hole in the blade shaft.

CAUTION:  
1. 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.  
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.

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.

FS3SP CONCRETE SAW — OPERATION  
WARNING  
WARNING  
Engine components can generate extreme  
heat.  
If the engine stalls for any reason during  
sawing, raise the blade out of the cut  
before restarting.  
Diamond Blades and Blade Speed  
10. The operator must recognize and adhere to the optimum  
speed that the saw advances while sawing. DO NOT force  
the saw in the cut. Observe the engine tachometer from time  
to time to get the feel for a smooth sawing pace relative to  
RPM.  
1. Diamond sawing consist of cutting WET (using water to cool  
the blade) or DRY (using the circulating air to cool the blade).  
2. Selecting the diamond blade type and grade defines how  
the blade will perform both in cutting speed and blade life.  
11. Factors for sawing economy:  
MULTIQUIP offers a full line of quality diamond blades  
to match up with your FS3SP, that provide the highest  
level of sawing value and performance

Model saw. [Use only Premium Lithium 12 based Grease,  
conforming to NLG1 Grade #2 consistency.]  
The following procedures devoted to mainte-  
nance can prevent serious saw damage or  
malfunctioning. Before servicing or inspection,  
ALWAYS park the saw on a level surface with  
the blade removed, and the Console Engine ON/OFF switch &  
Engine ON/OFF switch in “OFF” position.  
1. Front Wheels (2): Grease daily, see page 42, item 3,  
UndercarriageAssembly.  
2. RearWheels (2):Grease daily, see page 44, item 10, Rear  
AxleAssembly.  
WARNING  
3. Blade Shaft Bearings (2): Grease daily, see page 46,  
item6, 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 58,  
item20, Raise/LowerAssembly.  
5. Transmission Shaft Bearings (2): Grease weekly, see  
page 68, item 16,Transmission Assembly.

thread nut & bolt tightness, and overall cleanliness.  
2. ENGINE OIL:Check daily.Inspect with blade removed and  
saw frame level on a level surface. Keep the oil clean, and  
at the proper servicing level (Figure 7).DO NOT OVERFILL!  
SAE 10W-30 of SG is recommended for general use.  
NOTE  
When cutting DRY, lubricate blade shaft bearings 2  
to 3 times daily.The grease can provide an added  
protective seal for the bearings.  
3. ENGINE OIL CHANGE: Change engine oil the first month  
or 20 hours of operation.Then every 3 months/ or 50 HOURS  
NOTE  
ALWAYS dispose of used oil in a responsible  
manner.Ensure that the disposition of all hazardous  
waste is handled properly. Call your Recycling  
Center for information about recycling engine oil.

FS3SP CONCRETE SAW — MAINTENANCE  
GeneralTransmission Care  
AdjustV-Belt Alignment/Replacement Pulleys  
All FS3SP Models utilize spline gear wheel design coupled  
with an EATON Model 7 HydrostaticTransmission that provides  
forward/reverse propulsion. The simple design of the system  
keeps maintenance to a minimum.  
TheV-belts and their respective pulleys have been professionally  
aligned at the factory. If there is a requirement to remove/replace  
or adjust the pulleys, proceed with the following instructions.  
1. Select the proper sized pulley both in outside diameter and  
arbor size. Use approved Multiquip parts to ensure the  
component compatibility.
