The MQWhiteman FS1 Series Concrete Saws are designed for
wet or dry cutting utilizing diamond blades. They have been
engineered for general and industrial flat sawing applications.
The exceptional performance of these saws centers around
simple operating 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. A rugged
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, sturdy oversized wheels, and
industrial under carriage assembly ensure accurate tracking and
years of reliable use. A positive locking counter balance Raise/
Lower system with a depth meter easily orients blade elevation.
A hardy water plumbing system evenly distributes optimum water
volume & flow rate to both sides of the blade. Operator control of
the saw is safely accomplished with adjustable ergonomic
handlebars.
POWER PLANTS
The FS1 Saw Series provides a variety of gasoline engine
choices. Selection of a specific engine, and its capacity measured
in horsepower/torque, directly affects the performance of the
diamond blade. The FS1 series is generally classified in the
industry as a "LOW to 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. [See Table 3]
All FS1 saws are designed, engineered and manufactured with
strict adherence to American National Standards Institute, Inc.
(ANSI) guidelines B7.1 and B7.5.
A jig welded heavy steel gauge under carriage chassis assembly
supports the saw in tracking, pivoting and stabilization. Two rear
wheels (8" x 2.0" x 3/4") and two front wheels (4" x 2.0" x 3/4")
supports the chassis. The entire assembly pivots about the rear
carriage and is lubricated through 90-degree grease fitting in
the rear axle tube. [See page 38, Under Carriage Assembly]
BLADE DRIVE SYSTEM
A rugged 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. Two premium 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, and is designed for left and right hand cutting.
[See page 40, Blade Shaft Assembly]
BLADE GUARD ASSEMBLY
MANUAL RAISE/LOWER SYSTEM
A positive locking mechanical raise and lower spring tension
assembly supports elevation cycling operations. A rotating ball
handle permits the engage/disengage process, and the tension
spring assists the operator with smooth blade entry and egress.
Blade orientation is referenced on the front face of the handle
bar support tube and is calibrated for 12", 14", 16" and 18"
diamond blades. [See Figure 11 and page 22]
CCC
The two-piece heavy gauge 14" blade guard is designed with a
water system to meet the challenges of wet cutting operations. 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. The blade guard has a convenient "flip-up" front
cover for easy blade changes, and is spring tensioned for positive
up/down positioning. The blade guard may be oriented for left or
right hand cutting.
WATER SYSTEM
The FS1 Series employs a water system that provides floodwater
to the blade. 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 standard
"garden hose" hookup valve connects the water source to the
saw, and a 2-way water lever (ON/OFF) is conveniently located
for the operator. [See Figure 6 and page 48]

directional arrows on the blade, clockwise for right-hand
cutting and counter-clockwise for left-hand cutting, then
place the blade onto the blade shaft, and ensure the arbor
hole of the blade matches the diameter of the shaft.
5.Blade Drive Pin – Line up the blade drive pin with the
inner flange (collar) pin hole. The blade’s operating
directional arrows must point in a “down-cutting” direction
(whether cutting on right side or left) to perform correctly.
6.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.
7.Blade Shaft Torque Hole – A conveniently placed opening
on the frame that permits the use of the shaft lock wrench to
assist in blade changes. The pointed end of the locking
wrench fits into the saw frame hole and a machined hole in
the blade shaft. Once in place, the blade shaft can not
rotate making it easier to remove the blade nut.

working at high speeds, except for
extreme emergencies.
The FS 1 employs a front and rear pointer (Figure 22) that has
1.
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 22. Pointer View (Front/Rear)
2.For operator comfort, an ergonomically designed handle bar
adjusts by loosening two clamping knobs and adjusts to the
desired height. Tighten the knobs back down when the
desired height is met.
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” (51 mm). “Step-cutting” provides the optimum opportunity for the blade to cut fast and last its longest.
CAUTION:CAUTION:
CAUTION:
CAUTION:CAUTION:
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.
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.
WARNING
If the engine stalls for any reason during
sawing, raise the blade out of the cut
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 (Hose Connection below handle bars) on the saw. The
source pressure should be approximately 40 psi.
2.Select the “ON” position of the two-way water value, and
ensure the proper flow and rate 4-5 gallons/ minute (15-19
Lt/min) is equally directed to both side of the blade.
3.Advance engine throttle to full (FAST) position.
4.Slowly lower the blade onto your cut line by unlocking the
mechanical Raise/Lower lever (Figure 6); freeing the spring
assisted lowering assembly. Observe the depth of cut with
the depth feed scale, and lock in the depth with the Raise/
Lower handle.
interrupted, stop sawing immediately.
IF the water supply to your blade is

9.The operator must recognize and adhere to the optimum
speed that the saw advances while sawing. DO NOT

1.Ensure the proper DRY Cutting blade is selected for the job.
2.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 its longest. Airflow acts
as a blade coolant during sawing. Cutting too deep with one
pass, or exerting excessive forward/side-ward pressure may
damage the blade.

2.Matching the correct blade for the specific job and material
being cut optimizes performance and value.
3.Selection of the proper diamond blade consists of:
Finishing a Cut
1.Raise the blade out of the cut by utilizing the ball handle
adjustment assembly. Raise the blade high enough out of
the cut to clear the surface and allow the saw to be maneuvered.

2.Move the engine throttle lever to the idle (SLOW) position
(Figure 20).
3.Set the engine ON/OFF switch to the “OFF” position
(Figure 18).
4.Place the two-way water valve (Figure 6) in the “OFF”
position .
4.Selecting the “grade” of diamond blade often defines the
performance factors that can be achieved. Multiquip offers a
variety of diamond blade grades to provide the desired level
of valve and performance.
Blade Speed
1.A diamond blade’s performance is directly connected to
specific peripheral (rim) speeds.
2.The following shaft rotational speeds have been factory set
to ensure optimum blade performance.
Operating saw blades at rotational speeds
greater than those specified by the manufacture can cause blade damage, and may injure the user or others in the operating area.
to the performance and longevity of your saw.
The extreme environments of sawing operations require routine cleaning, lubrication, belt
tensioning, and inspection for wear and damage
WARNING
The following procedures devoted to maintenance can prevent serious saw damage or
malfunctioning. Before servicing or inspection,
ALWAYS park the saw on a level surface with
the engine ON/OFF switch in “OFF” position.
