FS2/FS2SP CONCRETE SAW — SAFETY MESSAGE ALERT SYMBOLS

FOR YOUR SAFETY AND THE SAFETY OF OTHERS!

Safety precautions should be followed at all times when
operating this equipment. Failure to read and understand the
Safety Messages and Operating Instructions could result in
injury to yourself and others.

HAZARD SYMBOLS

NOTE

This Owner's Manual has been developed to provide
complete instructions for the safe and efficient operation
of the MQWhiteman FS2 and FS2SP Concrete Saws.
Depending on the power plant you have selected, please
refer to the engine manufacturers instructions for data
relative to its safe operations.

Before using this Concrete Saw, ensure that the
operating individual has read and understands all
instructions in this manual.

SAFETY MESSAGE ALERT SYMBOLS

The three (3) Safety Messages shown below will inform you
about potential hazards that could injure you or others. The
Safety Messages specifically address the level of exposure to
the operator, and are preceded by one of three words: DANGER,

Lethal Exhaust Gases

Engine exhaust gases contain poisonous
carbon monoxide. This gas is colorless and

odorless, and can cause death if inhaled.
NEVER operate this equipment in a confined

area or enclosed structure that does not
provide ample free flow air.

Explosive Fuel

Gasoline is extremely flammable, and its
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.

DANGER: You WILL be KILLED or

SERIOUSLY injured if you do not follow
directions.

WARNING: You CAN be KILLED or

SERIOUSLY injured if you do not follow
directions.

CAUTION: You CAN be injured if you

do not follow directions.

Potential hazards associated with Concrete Saw operations
will be referenced with Hazard Symbols which appear
throughout this manual, and will be referenced in conjunction
with Safety Message Alert Symbols.

Burn Hazards

Engine components can generate extreme heat.
To prevent burns, DO NOT touch these areas
while the engine is running or immediately after
operations. Never operate the engine with heat
shields or heat guards removed.

Rotating Parts

NEVER operate equipment with covers, or

guards removed. Keep fingers, hands, hair and
clothing away from all moving parts to prevent
injury.

■

Use appropriate steel centered diamond blades manufactured
for use on concrete saws.

ALWAYS inspect diamond blades before each use. The blade

should exhibit no cracks, dings, or flaws in the steel centered
core and/or rim. Center (arbor) hole must be undamaged and
true.

Examine blade flanges for damage, excessive wear and
cleanliness before mounting blade. Blade should fit snugly on
the shaft and against the inside/outside blade flanges.

Ensure that the blade is marked with an operating speed greater
than the blade shaft speed of the saw.

Only cut the material that is specified by the diamond blade.
Read the specifications of the diamond blade to ensure the proper

FS2/FS2SP CONCRETE SAW — GENERAL INFORMATION

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.

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 (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.

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/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.

All MQ Whiteman 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.

FS2/FS2SP 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 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.

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.

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

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 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 44.

disconnect manifold fittings, and either a 14" or 20" blade guard.
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
guard incorporates an independent water misting system that utilizes
specifically positioned aerosol spray nozzles to support dust
suppression when sawing in minimal water environments.

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.

BLADE GUARD ASSEMBLY

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.

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.

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
for blade selection with respect to depth of cut. Blade orientation is
referenced on the console's depth feed gauge.

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
jet nozzles, in conjunction with the design of the 14" blade guard,
provides exceptional dust suppression.
