MQ SP2 SLAB SAW — MAJOR COMPONENTS
Figure 3. SP2 Saw Major Components
Figure 3 displays the location of the various operational control
features of the MQ SP2 slab saw. Features are dependent on the
specific model saw selected. The function of each console component
or indicator is explained below:
1. Handle Bars – Used to steer and push the SP2 slab saw
during cutting operations. The handle can be folded down
for transportation.
2. Forward/Reverse Speed Lever – Controls forward and
reverse speeds for self-propelled operation. Provides
positive neutral for engine start. ALWAYS place
transmission engage/disengage lever in the engage
position before setting speed lever (self-propelled models
only).
3. Raise/Lower Crank Handle – Physically orients saw
(raises or lowers) depending on cranking direction (CW or
CCW). Turning the handle
turning the saw counter-clockwise
clockwise
lowers the saw,
raises the saw.
4. Transmission Engage/Disengage Lever – Forward
locking position engages transmission. Rear Locking
position disengages transmission from rear axle and
permits "free wheeling" (self-propelled models only).
5. Water Tank – A 5-gallon capacity water tank provides water
for the saw blade during wet cutting applications.
6. Water ON/OFF Valve – ON position
permits water to flow from source through saw water hose.
OFF position
7. Hydraulic Drive Transmission - Controls the saw's
forward and reverse movement by using the
reverse speed lever
8. Saw Blade Guard –
operations & allows water hoses to be connected to the
cover for wet cutting.
9. Belt Cover – Covers the drive shaft belt, engine pulley
and the hydraulic transmission belt (on self-propelled
models only).
10. Drive-Shaft Pulley Guard – Covers the drive shaft pulley.
11. Rear Wheels – Allows the saw to be rolled across ground.
On self-propelled models, the rear wheels are turned by
the spline gears attached to the hydraulic transmission
system.
12. Pointer Arm – Front pointer wheel assists in straight
tracking. Lifts up for storage and pivots down for use.
13. Lifting Bale Kit – Allows for easy lifting and transporting
the MQ SP2 slab saw.

MQ SP2 SLAB SAW — GENERAL INFORMATION
Familiarization
The SP2 series
of concrete or asphalt utilizing diamond blades. They have been
engineered for general, industrial and high production flat cutting
applications. The reinforced steel box frame design adds strength
necessary to reduce vibrations while cutting. Minimizing
vibrations enhances the performance of the blade and extends
the life of the saw.
Heavy-duty front and rear axles, sturdy oversized wheels and
industrial undercarriage assembly ensures accurate tracking and
years of reliable use.
Additionally, the general weight-to-strength ration design of the
frame and chassis assembly provides 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.
Power Plants
The SP2 series slab saws are generally classified in the industry
as LOW to MEDIUM horsepower saws. This classification is
particularly useful when selecting the proper diamond blade for
an application.
There are two gasoline engines used with the SP2 series saws:
13 HP Honda GX390K1QWT2
A
cylinder, OVH rated at 3600 RPM and a
GX620TXF2
RPM. Blade rotation is v-belt driven. This is accomplished by
connecting to the output shaft of the engine to an upper drive
pulley. The lower drive pulley (Blade) is then connected to the
upper drive pulley (Engine) by three V-belts. As the engine shaft
rotates, so does the blade.
Refer to the engines Owner's Manual for the specific instructions
regarding engine operation and maintenance practices.

Water System
All saws provide a water direction system to provide cooling
water to the diamond blade. This system consists of: a standard
"garden hose" valve that connects to the water source (via hose)
to the saw, an
The 20-inch blade guard is designed with two 6-inch vinyl water
tubes to direct water to the diamond blade.
Under Carriage System
A jig welded heavy steel gauge under carriage assembly
supports the saw in tracking, pivoting and stabilization. A rear
axle supports two solid rubber cast hub wheels with roller
bearings, grease fittings and locking collars. A front axle supports
two solid rubber cast hub wheels with roller bearings, grease
fittings and locking collars. The assembly pivots about two rocker
blocks with bushings.
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, 3 V-belts (13HP, 4 V-belts for 20HP models)
connect to the engine pulley to the blade shaft pulley. The 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.
Water System
The MQ SP2 slab saw comes standard with a 20-inch hinged
two piece, heavy steel gauge blade guard. The blade guard
provides access for vinyl water tubes that supply optimum volume
and dispersal of water for cooling and/or dust suppression.

MQ SP2 SLAB SAW — OPERATION
Traveling During Cutting (Push)
Push models of the SP2 saw must be manually moved by the
operator during cutting operations. Ensure that the handlebars
are secured in place on the console and push against them with
a controlled amount of force to prevent losing control of the
machine.
CAUTICAUTI
CAUTION
CAUTICAUTI
DO NOT force the blade into the cut any faster than its
designed tendency is effective cut and remove material. This
can damage your blade and/or your machine.
Traveling During Cutting (Self-Propelled)
Self-propelled models of the SP2 saw have a hydrostatic transmission which mechanically propels the saw during cutting
operations. To prepare the machine for self-propelled cutting:
1. Place the
travel lever
in the NEUTRAL position.
3. Move the
increase forward travel speed during cutting (Figure 40).
Placing the travel lever fully forward will move the saw at
maximum speed.
Figure 40. Transmission Engage/Disengage Lever
4. When reverse movement is required, move the
towards the REVERSE position (Figure 41). Placing the
travel lever fully in reverse will move the saw backwards at its
maximum reverse speed.

Saw Alignment
1.
The SP2 saw employs a front pointer (Figure 42) that has
been precisely aligned with the diamond blade at the factory.
Referencing the figure below, accurate tracking is accomplished by referencing the front pointer tip over the cut line.
Precise saw direction is accomplished by slight operator
pressure against the handle bars.

DANGERDANGER
DO NOT operate this machine without
the Blade Guard or V-belt Guards in
place. While the blade is spinning, DO
NOT place hands, feet, or other body
parts near the blade to avoid
SERIOUS INJURY or DEATH.
When cutting, determine the required cutting depth and use an
appropriately sized blade. Deep sawing is wasteful to the life of
the blade.
The preferred method of sawing is to
2” (51 mm). Step Cutting provides the optimum opportunity for the
blade to cut fast and last longest.
Wet Cutting Operation
1. Connect hose from water source (on-board water tank or
external water source) to the hose fitting connection
(Figure 3) of the saw. The source pressure should be
approximately 30-40 psi.
2. Ensure the vinyl water tubes are properly inserted into the
blade guard holes and are clear of any obstructions.
3. Turn water source on (Figure 43).

5. Align the saw along the cut line utilizing the front pointer.
ALWAYS saw in a straight line only. SERIOUS DAMAGE to
the blade or saw may occur if the saw is twisted or forced to
cut radius shapes.
