SILICOSIS/RESPIRATORY WARNINGS
WARNING WARNING
SILICOSIS WARNING
RESPIRATORY HAZARDS
Grinding/cutting/drilling of masonry, concrete, metal and
other materials with silica in their composition may give
off dust or mists containing crystalline silica. Silica is a
basic component of sand, quartz, brick clay, granite and
numerous other minerals and rocks. Repeated and/or
substantial inhalation of airborne crystalline silica can
cause serious or fatal respiratory diseases, including
silicosis. In addition, California and some other
authorities have listed respirable crystalline silica as a
substance known to cause cancer. When cutting such
materials, always follow the respiratory precautions
mentioned above.
Grinding/cutting/drilling of masonry, concrete, metal and
other materials can generate dust, mists and fumes
containing chemicals known to cause serious or fatal
injury or illness, such as respiratory disease, cancer,
birth defects or other reproductive harm. If you are
unfamiliar with the risks associated with the particular
process and/or material being cut or the composition of
the tool being used, review the material safety data
sheet and/or consult your employer, the material
manufacturer/supplier, governmental agencies such as
OSHA and NIOSH and other sources on hazardous
materials. California and some other authorities, for
instance, have published lists of substances known to
cause cancer, reproductive toxicity, or other harmful
effects.
Control dust, mist and fumes at the source where
possible. In this regard use good work practices and
follow the recommendations of the manufacturers or
suppliers, OSHA/NIOSH, and occupational and trade
associations. Water should be used for dust
suppression when wet cutting is feasible. When the
hazards from inhalation of dust, mists and fumes cannot
be eliminated, the operator and any bystanders should
always wear a respirator approved by NIOSH/MSHA for
the materials being used.

■
Understanding the capability of your saw
Understanding the specifications of the engine
Understanding the blade shaft speed of your saw
Understanding diamond blade operating limitations
The depth of cut required
Cutting conditions
Desired cutting performance requirements
Engine (RPM) and Surface Feet per Minute (SFPM)
Speeds
This saw uses a belt drive system to propel the diamond
blade. Specifically sized engine drive and blade shaft
pulleys, engine (RPM) and blade diameter determine the
ultimate peripheral speed (SFPM) of the diamond blade. It
is important to understand the SFPM speed — For safety
and performance, it is essential that the selected
diameter diamond blade be matched up to a proper
SFPM. See Table 8.
Four 4030 models are available (403016, 403020, 403026,
403030), and are designed with different pulley ratio speeds
to govern the blade shaft RPM output.The combination of
the different diameters of the pulleys along with engine
(RPM) determines this ratio that ultimately provides a RPM
speed at the blade shaft (Figure 7).

Blade RPM vs. Surface Feet Per Minute (SFPM)
CAUTION
When choosing a blade for your cutting conditions, follow
the blade manufacturer’s recommendations. Match the
blade speed (blade shaft RPM) to the recommended blade
surface feet per minute (SFPM). See Table 8.
Verify the engine start switch is OFF before removing
or installing a blade.
Tighten the 5/8" blade-mounting bolt to 125-175 ft. lbs.

SPECIFIC TOOLS / SAW BLADES
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.
SPECIFICTOOLSTO BE USED
This saw is to use tools (blades) as follows:
Steel core segmented or continuous diamond rim cutting
wheel
4. Directional Arrow — Check to ensure that the blade
is oriented properly on the spindle for sawing. Reference
the directional arrow on the blade and place it so the
direction of rotation “downcuts” with the turn of the shaft.
Any other type of tool is not to be used.
SAW BLADES
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.
WARNING — Inspect Diamond Blade
Failure to thoroughly inspect the diamond blade (Figure
8) for operational safety could result in damage to the
blade or the saw and may cause injury to the user or
others in the operating area. Discard damaged or worn
blades and replace with fresh blade.
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 shaft arbor, and that it is free
from distortions. Correct blade flanges (collars) must
be used.The inside face of the flanges must be clean
and free of debris. An out of round arbor condition will
cause damage to the blade and the saw.
Figure 8. Diamond Blade
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. All blades
used must be designed for the maximum spindle RPM.
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

INSTALLING THE BLADE
INSTALLING THE BLADE
The blade can be mounted on either side of the saw to
accomodate different cutting jobs. With the proper sized
blade selected, reference the following procedure to install
the new blade.
Ensure the flange faces are kept clean and
smooth as well as the inside diameter of the
blade shaft.
Figure 10. Aligning Flange Pin Through Blade
(Standard Blade Flange System shown)
1. Raise the saw so the blade will clear the ground when
installed.
WARNING —Tighten Blade Mounting Bolt
2. Remove the blade flange bolt. This bolt is LEFT-HAND
thread on the RIGHT side of the saw and RIGHT-HAND
thread on the LEFT side of the saw.
Failure to properly tighten the blade mounting bolt can
result in the bolts coming loose with the blade flange
potentially falling off the rotating blade shaft assembly.
The blade and other parts coming loose from the saw
during operation pose a high risk of serious injury or
even death!
3. Verify the blade flanges are clean and not damaged. Pay
particular attention to all holes and recesses (Figure 9).
6. With the blade still off the ground, tighten mounting bolt
as tight as can be achieved until blade spins. (Figure 11,
Item B shows tightening direction for blade mounted
on RIGHT side of saw.)

INSTALLING THE BLADE
Stacking Blades for Wide Cuts
CAUTION — ImproperTorque
Combining, or stacking blades together to make wide cuts
requires an optional bushing extension kit.
An improperly torqued mounting bolt can cause the
inside diameter of the blade, blade shaft, and flange
bushing to quickly wear. This can result in poor cutting
characteristics or premature failure of these parts
requiring replacement and machine “downtime.”
WARNING
NEVER attempt to stack blades beyond the capacity
of the kits described here. NEVER operate the saw
without blade guards in place.

RAISE-LOWER CONTROLS
RAISE - LOWER CONTROLS
SETTINGTHE DEPTH STOP
The MQ SP4030 saw uses a 24-volt motor and hydraulic
cylinder to raise and lower the saw.The raise-lower function
is controlled by the operator through a 3-position toggle
switch on the raise-lower control handle located on the
operator’s control panel.
The SP4030 saw uses a controlled depth stop to position
and set the blade at a desired cut depth (Figure 26).
Figure 26. Depth Stop
Figure 24. Raise-Lower Control Toggle Switch
If a blade is changed for any reason, or if
wear is suspected since the last time
depth stop was set, you will need to reset
the depth stop. If a cut at a precise depth is
necessary, it is best to make a pre-cut and
MEASURE at deepest part of cut to confirm
cut is at desired depth.
1. To lower the blade, push the toggle switch located on
the end of the control handle FORWARD (Figure 24).
2. To raise the blade, pull the toggle switch located on
the end of the control handle BACKWARD.
Setting the Depth Indicator
1. Lower the blade until it just touches the cutting surface.
WARNING
2. Set the Depth Indicator dial to zero.(The depth indicator
now accurately indicates how deep the blade is cutting.)
See Figure 25.
Always adhere to manufacturer’s blade speed
recommendations for surface feet per minute when
choosing a blade for your cutting conditions. See blade
size/speed information section.

RAISE-LOWER CONTROLS/WHEEL DRIVE SYSTEM
To control the depth of cut with saw running and blade
mounted:
WHEEL DRIVE SYSTEM
The 4030 Series features a cable-controlled hydraulic
powered gear motor system with infinite Forward-Neutral-
Reverse (F-N-R) speed adjustment. This is controlled by
the operator through the speed control handle located on
the control panel. The saw is designed with a locked axle
drive and can travel forward at transportation speeds up to
275 feet per minute.
1. Set depth indicator as outlined on previous page.
2. Loosen pointer knob (Figure 27, item 1).
3. Rotate pointer to desired depth (Figure 27, item 2).
4. Re-tighten pointer knob to lock-in cutting depth.
A bi-directional variable displacement transmission pump
powers two hydraulic wheel motors that are directly coupled
to the wheels. This design provides vehicle propulsion in
both forward and reverse depending on the position and
direction of movement of the F-N-R control handle. The
wheel drive system also provides dynamic braking action.

To increase the forward speed, slowly move the control
handle FORWARD.
To decrease the forward speed, pull the control handle
BACKWARD.
When the control handle is in the neutral position, the
saw will have neither a forward nor reverse motion.
As the control handle is passed backward through the
neutral position the saw will start to move in REVERSE.
Reverse speed is also controlled by the position of the
control handle.

DRIVE SYSTEM ALIGNMENT
To ensure correct blade shaft/wheel alignment, this
operation should be performed by and authorized service
center.
In addition to blade alignment, maintaining proper blade
and drive system alignment will allow the saw to cut lines
that are straight without much effort. Therefore the front
wheels and blade shaft axles MUST be at right angles to
the frame edge.
Blade Alignment
Maintaining proper blade and drive system alignment will
allow the saw to cut lines that are straight without much
effort. Therefore the blade shaft flanges MUST be
equadistant to the sides of the saw, (+/- .030"). See Figure
50 below where distance A must equal distance B.
In Figure 51 you see the distance “A” on the right side is
shown as “A + .187"” which means that the distance
between centers of the front and rear drive axles are 3/16"
longer than on the opposite side. This will have the effect
of causing the saw to “steer” slightly to the left. After
becoming familar with the saws particular sawing
characteristics, the operator may wish to have this alignment
altered to fit his own preferences or to fit a particular
application.
The second requirement for the blade is that it MUST be
square to horizontal (90o to flat surface). See Figure 50.

training from someone that is familar with this operation.
Because of the tapered fit between the blade flange
and blade shaft, 5-10 tons of force is required to release
the inner flange from the blade shaft. Both parts and
tools can become dangerous projectiles if instructions
are not followed properly.
If the inner flange does not readily break free
from the tapered blade shaft while the center
puller bolt is tightened, lightly tap on the
center puller bolt to allow the flange to break
free from the shaft.

6. Loosen the mounting bolt and remove the outer flange
and bushing.
Installing the Inner Blade Flange
1. Ensure that the tapered portion of the blade shaft and the
inner blade flange are clean and free of burrs or indentations.
Clean and repair as necessary.See Figure 54.
7. Inspect the inner flange to ensure the proper seating
of the tapered fit. The inner flange should be seated
between .030" and 0.0" (flush) to the end of the blade
shaft. See Figure 55.
2. Ensure the drive key is in place (Figure 54, item 6).
3. Slide the inner flange (item 5) onto the tapered portion
of the blade shaft (item 7).

Figure 57. Depth Adjustment
While adjustment of the depth stop limiting
bolts can change the maximum usable cut
depth, they should not be adjusted to
compensate for unit “wobble” or blade/cut
problems. These indications are a result of
other issues that should be addressed.
5. Adjust the left-side stop bolt (item 1) in or out until the
blade flange or lower belt guard achieves 1/8" to 3/16"
ground clearance. Tighten lock nut on left side.
6. Raise saw and place 2 jack stands under the blade
shaft housing.
The saw comes factory-adjusted for maximum usable cut
depth. Should this setting need to be changed, perform the
following:
7. While holding the raise-lower Switch in the Lowering
position, raise the front axle assembly until it contacts
the left-side depth limiting stop bolt.
1. With the BLADE REMOVED, park the saw on a flat
and level surface.
8. While holding the axle firmly against the left-side depth
limiting stop bolt, screw the right-side depth limiting
stop bolt out until it makes contact with the axle.Tighten
lock nut on right side.
2. Fully lower the saw onto the depth limiting stop bolts.
3. Measure the distance from the blade flanges to the
surface.
Following this procedure will prevent torsional stresses
being applied to the frame when fully lowered due to uneven
adjustment of depth limiting stop bolts.
4. If adjustment is required, loosen locknut on the right-
side depth limiting stop bolt (Figure 57, item 2) and
screw bolt in several turns until it no longer makes
contact with the axle.
