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.

MQ PS4030 SAW — CHOOSING PROPER BLADE SIZE
Choosing Proper Blade Size
2800 (engine RPM) / 2000 (desired BS RPM) = 1.4
To select the proper size blade for the job requires an understanding
of the cutting capability of your saw and its relationship between
engine power, (as reflected in the engine RPM), and the speed
(RPM) of the Blade Shaft. The diesel engine of the MQ PS4030 runs
at 2800 RPM (full load). If 2800 RPM was a desirable Blade Shaft
speed for the average conditions in which you work, we would use
thesamesizesheaveontheengineshaftandthebladeshaftmaking
the resulting ratio between the two of 1:1. (See figure 8.)
This is the ratio 1.4 : 1, which means that for every 1.4 revolutions of
the engine, the Blade Shaft only turns once.
Ratios greater than 1 : 1 also have the beneficial effect of increasing
thetorqueoftheBladeShaft bythesamefactor(1.4inourexample).
The manufacturer advertises the Deutz 2011 Series diesel engine
develops 133 ft. lbs. (max) of torque. To find the theoretical Blade
Shaft torque of our example saw setup:
133 x 1.4 = 186.2 ft. lbs.
Actualtorqueofthesawwillvarysomewhat. Ingeneral, moretorque
means more cutting power.
1.4 : 1 Ratio
Figure 8. Blade Shaft Ratios
1 : 1 Ratio
Typically, however, the ratios are not used to design a level of torque;
they are used to create optimum blade speed (Blade Shaft RPM) for
your application.
If, however, for your cutting conditions, you need a Blade Shaft speed
slower than the engine speed (and this usually is the case), we then
need to INCREASE the ratio between the two speeds by using a
larger diameter sheave on the Blade Shaft, which will cause the
Blade Shaft to run slower than the engine speed. If, for example, you
know from experience that you need a Blade Shaft speed of 2000
RPM for the size of blade you normally use, divide the engine speed
RPM by the desired blade speed RPM (refer to the Blade RPM vs.
SFPM Chart,Table 7.)
The major factors are:

CAUTION
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. of
torque.
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 7.

MQ PS4030 SAW — SPECIFIC TOOLS / SAW BLADES
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.
SPECIFICTOOLSTO BE USED
This saw is to use tools (blades) as follows:
Steel Core Segmented or Continuous Diamond Rim
Cutting Wheel.
Any other type of tool is not to be used.
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.
WARNING
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.
Failure to thoroughly inspect the diamond blade, (Figure 9)
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.
4.
5.
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.
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.
Figure 9. Diamond Blade
6.
7.
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.
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 & 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. All blades used must be designed
for the maximum spindle RPM.

MQ PS4030 SAW — OPERATION
Wheel Drive System
STARTING AND STOPPINGTHE ENGINE
The MQ PS4030 saw features a cable-controlled hydrostatic
transmission with infinite Forward-Neutral-Reverse (F-N-R)
speed adjustment. This is controlled by the operation through
the control handle located on the operator control panel. The
saw is designed with locked axle drive, and can travel at speeds
up to 275 feet per minute.
WARNING
DO NOT leave the saw unattended while the engine is
running. NEVER start, park, or leave the saw unattended on
a slope.
A bi-directional variable displacement transmission pump
powers two hydraulic wheel motors that are directly coupled to
the wheels. The hydrostatic transmission provides vehicle
propulsion in both forward and reverse depending on the position
and direction of movement of the F-N-R control handle. The
hydrostatic transmission also provides dynamic braking action.
CAUTION
Allow the engine to warm up before increasing engine
speed.

a 15/16" or 1" nut to set belt tension by positioning an arm
between theTensioner Pulley and theTensioner Base. Ridges
on the Base mark the amount of tension.
Blade Shaft Assembly
Adjust to 3-1/2 notches on the tensioner:
1. Loosen the 9/16" nut.
2. Rotate the Tensioner Nut clockwise until the desired belt
tension is achieved.
3. Tighten the 9/16"nut.

Removal and Replacement
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
In Figure 53 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.
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 52 below where distance A must
equal distance B.
The second requirement for the blade is that it MUST be square
to horizontal (90o to flat surface). See Figure 52.

Blade Flange Removal/Installation
Correct removal or installation of the Inner Blade Flange requires
Flange Puller (p/n 18503) as shown in figure 55.
2. While the 3 perimeter bolts hold the two Puller Plates
together, slide the Horseshoe Plate of the Flange Puller
behind the (Shaft) side of the Inner Flange.
3. Tighten the center puller bolt to remove the Inner Flange
from the Blade Shaft.
WARNING
If unfamilar with this operation seek assistance or 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.

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 Stop Limiting
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.
4. If adjustment is required, loosen Locknut on the right-side
Depth Limiting Stop Bolt and screw bolt in several turns
until it no longer makes contact with the axle.
Following this procedure will prevent torsional stresses being
applied to the frame when fully lowered due to uneven adjustment
of Depth Limiting Stop Bolts.

Drain fuel from fuel tank and fuel lines.
Clean exterior with a cloth soaked in clean oil.
2. Remove the oil reservoir cap to speed oil draining.
Store unit covered with plastic sheet in moisture and dust-
free location out of direct sunlight.
3. When re-filling the system, raise the saw halfway up, then
lift the rear of the saw until the Blade Flanges touch the
ground. This will help to speed the filling process.
CAUTION
Never store the saw with fuel in the tank for any extended
period of time.Always clean up spilled fuel immediately.
4. After filling the system, jack the saw up so the drive wheels
are off the ground. Start the saw and move the Control
Handle half way into FORWARD to purge air out of the
system.
