MQ SP2 SLAB SAW — GENERAL INFORMATION
Familiarization
Water System
The SP2 series slab saws are designed for wet or dry cutting
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.
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 ON/OFF console water valve'
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:
A 13 HP Honda GX390K1QWT2 air-cooled, 4-stroke single
cylinder, OVH rated at 3600 RPM and a 20HP Honda
GX620TXF2 air-cooled, 4-stroke OVH 90° V-twin rated at 3600
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.
Console
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.
An ergonomically designed control console allows the operator
to easily understand and/or operate the adjustable handlebars,
Raise/Lower Crank Handle, and transmission engage/
disengage lever (Self-propelled models only). Additionally, for
self-propelled models, the console also provides forward/reverse
controls.
Manual Raise/Lower System
The SP2 slab saw uses an ACME thread, manual raise/lower
assembly easily raises and lowers the blade and can lock into
position to ensure a constant depth when cutting. See Table 6 for
blade selection with respect to depth of cut.
NOTE
All MQ series SP2 slab saws are
designed, engineered and
manufactured with strict
adherence to American National
Standards Institute, Inc. (ANSI)
guidelines B7.1 and B7.5

MQ SP2 SLAB SAW — INSPECTION -BLADE
WARNING
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.
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.
D
Failure to thoroughly inspect the diamond blade (Figure 11)
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.
Figure 11. 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.

Cutting
WARNING
The operator MUST wear
the appropriate protective
equipment and clothing while engaged in sawing. Failure
to do so can result in SERIOUS INJURY.
DANGER
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 Step Cut in increments of
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).
Figure 44. Water System ON/OFF Valve
5. Align the saw along the cut line utilizing the front pointer.
CAUTI
CAUTION
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.
6. Slowly lower the diamond blade onto the cut line by cranking
the Raise/Lower handle CLOCKWISE (Figure 37). When
the handle can no longer be turned, the blade will be at its full
rated depth.
WARNING
If the water supply to your blade is interrupted, STOP cutting
immediately to prevent damage to your blade
and/or saw.
If the engine stalls for ANY reason during cutting, raise the
blade out of the cut before restarting.
7. For self-propelled models, follow steps 1-4 of the Traveling
During Cutting (Self-Propelled) section.
For push models, use the Traveling During Cutting (Push)
instructions.
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 side of
the handle bar as you slowly advance the saw forward.
CAUTI
CAUTION
Figure 43. On-board Water Tank ON/OFF Valve
4. Open the water system valve on the left side of the console
by moving the lever to the ON position (Figure 44) and ensure
the water is flowing equally to both sides of the diamond
blade.
DO NOT force the blade into the cut any faster than its design
will allow. This can damage your blade and/or your machine.
Dry Cutting Operation
When dry cutting, follow steps 5-8 of the Wet Cutting Operation
section.

MQ SP2 SLAB SAW — OPERATION
Finishing A Cut
Diamond Blades
1. Raise the blade out of the cut by cranking the Raise/Lower
handle COUNTER-CLOCKWISE (Figure 37). Raise the
blade high enough out of the cut to clear the surface and allow
the saw to be maneuvered.
Diamond blade sawing consists of cutting WET (using water to
cool the blade) or DRY (using the circulating air to cool the blade).
Selecting the diamond blade TYPE and GRADE defines how
the blade will perform both in cutting speed and blade life.
Selection of the proper diamond blade consists of:
z Determining WET or DRY cutting
2. Move the engine throttle lever to the idle (SLOW) position
(Figure 30, 33).
3. Set the engine ON/OFF switch to the OFF position (Figure
31, 34).
4. Place the water valve (Figure 44) in the OFF position (as
required).

MQ SP2 SLAB SAW — MAINTENANCE
Maintenance
Engine air filter:
Clean air filter 2 to 3 times daily when DRY cutting. See
Engine Owner’s Manual for detailed information.
WARNING
General maintenance practices are crucial 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
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 blade removed, and the
Console Engine ON/OFF switch & Engine
ON/OFF switch in “OFF” position.
Some maintenance operations may require the engine to be run. Ensure that
the maintenance area is well ventilated.
Exhaust contains poisonous carbon monoxide gas that can cause of unconsciousness and may result in DEATH.
General Cleanliness
Clean the machine daily. Remove all dust and slurry build up. If
the saw is steam cleaned, ensure that lubrication is accomplished
AFTER steam cleaning operations.
General Engine Care
Engine tank & strainer:
Clean every year/or 300 hours.
Fuel line:
Replace every two years/or as necessary.
Spark plug:
Clean/adjust every 6 months/or 100 hours. Replace every
year/ or 300 hours.
Bearing Lubrication Care
There are four grease points for the SP2 saw. [Use only Premium
Lithium 12 based Grease, conforming to NLG1 Grade #2
consistency.]
Rear Wheels (1):
Grease daily, see Undercarriage Assy., item 10
Blade Shaft Bearings (2):
Grease daily, see Blade Shaft Assy., item 15
Raise/Lower Adjust Tube (1):
Grease daily, see Raise/Lower Assy., item 2
NOTE
When cutting DRY, lubricate blade
shaft bearings 2 to 3 times daily.
The grease can provide an added
protective seal for the bearings.
Engine check:
Check daily for any oil and/or fuel leakage, thread nut & bolt
tightness, and overall cleanliness.
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 8). DO NOT OVERFILL! SAE 10W30 of SG is recommended for general use.
Engine oil change:
Change engine oil the first month or 20 hours of operation.
Then every 3 months/or 50 HOURS of operation. See Engine
Owner’s Manual for detailed information.
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.
PAGE 32 — MQ SP2 SLAB SAW — PARTS & OPERATION MANUAL — REV. #7 (09/08/06)
MQ SP2 SLAB SAW — MAINTENANCE
General Transmission Care (Self-Propelled Models only)
All SP2 model saws 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.
Transmission Reservoir Cup:
Check every 8 hours of operation. When the transmission
is cold (A), check oil level against the level indicator (see
Figure 45).
Spline Gear Wheels:
Check every 25 hours and clean as necessary. If the spline
wheels DO NOT engage the rear wheels with sufficient
pressure, slippage of the rear wheels may occur.
To adjust the Spline Gear Assembly:
1. Place the transmission engage/disengage lever in the
DISENGAGE position (Figure 46) .
CAUTION
DO NOT use multiple viscosity oils! DO NOT OVERFILL.
Figure 46. Transmission Engage/Disengage Lever
(Disengage Position)
Figure 45. Transmission Reservoir
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, M2C41A or International Harvester Hy-Tran fluids. For extreme
hot weather, drain oil and refill with an oil having a viscosity
of SAE30W-30 or SAE40W-40.
3. Loosen the linkage adjustment nut and slightly lengthen the
linkage rod (see Transmission Engage Lever Assy., items 11
and 13).
4. Move the transmission engage/disengage lever to the
ENGAGE position to observe the proper spline-to-rear wheel
contact.
5. Retighten the adjustment nut.
Drive Chain:
Check every 50 hours. Periodically wipe the chain clean and
re-lubricate with penetrating chain oil.
The drive chain may stretch requiring tension adjustments.
To adjust the drive chain tension:
1. Loosen the (3) transmission attachment screws (Hydrostatic.
Transmission Assy., item 2)
2. Pivot the transmission in the “U” slots of the transmission
mount until the proper tension is achieved (Hydrostatic
Transmission Assy., item 7).
NOTE
Excessive tension on the drive chain
will reduce chain life.
