FS3SP CONCRETE SAW — GENERAL INFORMATION

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
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

FS3SP CONCRETE SAW — GENERAL INFORMATION

UNDER CARRIAGE SYSTEM

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.
See pages 56.

the blade guard raised. The blade exposure cannot exceed 180
degrees during operations. Adhere to the safety guidelines of
the American National Standards Institute (ANSI) B7.1 and

B7.5.

Figure 14. Blade Guard

NEVER attempt to check the V-belt with the engine running

because severe injury can occur. Keep fingers, hands, hair and
clothing away from all moving parts.

V-belts Alignment and Tensioning

This concrete saw is equipped with four premium V-belts that
have been aligned and tensioned by factory personnel. All four
V-belts MUST be installed for proper operation of the saw. Failure
to run the saw with less than four belts may damage the saw or
equipment.

Use the following procedure to check the alignment of V-belts:

1. Remove the bolts that secure the V-belt cover (Figure 16) to
the saw frame.

CHECK the following on the "blade guard":

■

Check to ensure the capacity of the blade guard matches the

diameter of your diamond blade.

■

Check that the guard seats firmly upon the bayonet fitting of

the saw frame.

■

Check that the spring tensioned front cover of the guard is

firmly seated with the rear section of the guard, and there are
no gaps.

■

Check the fit of the water hoses about the two water manifolds

(14" guard). NEVER lift the blade guard while cutting.

■

Check that the flood water tubes and water jets are clear and

open. Test the water supply for pressure and flow (to both
sides of the blade) before sawing operations.

CHECK the following on the "blade flange cover":

■

Check that the flange cover seats firmly upon the bayonet

fitting of the saw frame prior to operation.

FS3SP CONCRETE SAW — OPERATION

Saw Alignment

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.

Figure 24. Saw Pointers (Front/Rear)

2.

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.

8. The rotation of the blade creates a tendency for the saw to
slightly pull in a particular direction. To ensure a straight line
of sawing, apply pressure against the appropriate handle bar

FS3SP CONCRETE SAW — MAINTENANCE

General Transmission Care

All FS3SP Models utilize spline gear wheel design coupled
with an EATON Model 7 Hydrostatic Transmission that provides
forward/reverse propulsion. The simple design of the system
keeps maintenance to a minimum.

1. Transmission Reservoir Cup: Check every 8 hours

cold

of operation. When the transmission is
level against the level indicator (see Figure 25).

DO NOT use multiple viscosity oils! DO NOT OVERFILL.

Figure 25. Transmission Reservoir

2. Servicing: The transmission reservoir is factory filled.
Should servicing be required, use SAE20W-20, API classi­fication (SE,CC,CD) or better, General Motors Dexron B,
Ford M2C-33F, M2C-41A or International Harvester Hy-Tran
fluids. For extreme

Adjust V-Belt Alignment/Replacement Pulleys

The V-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.

2. A change in Pulley diameters may require specifically sized
V-Belts. Contact Multiquip Servive Department to en-

sure V-Belt compatibility.

Complete Drive V-Belt(s) Replacement steps (1 through 7)

3. Remove the V-Belts from around the Pulley(s).

4. Remove the set screws that secure the pulleys to the respec­tive shafts (PTO shaft) for engine pulley or the (bade shaft)
for the blade shaft pulley.

5. Remove/replace the pulley by sliding it off the shaft.

6. Reorient the new pulley on the shaft, and ensure precise
pulley alignment by utilizing an accurate straight edge (see
Figures 26 and 27).

7. Replace/tighten set screws treated with a drop of

Threadlocker 266.

8. Orient the proper replacement V-Belt(s) around the blade
shaft pulley and engine pulley.

9. Reference the final stages of the Drive V-Belt(s) Replace-

ment steps.

3. Drive Chain: Check every 50 hours. Periodically wipe the
chain clean and relubricate with penetrating chain oil.

The drive chain may stretch requiring tension adjustments.
Loosen the (3) transmission attachment screws (see page
68, item 11), and pivot the transmission in the
