MQ STREET PRO 1 CE SAW — SILICOSIS/RESPIRATORY WARNINGS
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.
WARNING
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.

Diamond Blade Safety
■
■
■
■
■
■
■
■
Use appropriate steel centered diamond blades
manufactured for use on concrete saws. See further blade
information on pages 17 to 19.
WARNING
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 and excessive wear.
Ensure the cleanliness of the blade before blade is installed.
Blade should fit snugly on the shaft and against the inside/
outside blade flanges.
Ensure the blade is marked with an operating speed greater
than the spindle speed of the saw.
Only cut the material that is specified for the diamond blade.
Read the specifications of the diamond blade to ensure the
proper tool has been matched to the material being cut. The
saw has been engineered for WET CUTTING. Ensure a
WET CUTTING blade is being used and that the water supply
system to the blade is properly functioning and being used.
ALWAYS keep blade guards in place. Exposure of the
diamond blade must not exceed 180 degrees.
Ensure that the diamond blade does not come into contact
with the ground or surface during transportation. DO NOT
drop the diamond blade on ground or surface.
The engine governor is set to permit maximum engine speed
in a no-load condition. Do not tamper with the engine
governor to increase the speed. Increasing the engine speed
could allow the maximum rated spindle speed to be
exceeded, creating an unsafe condition.
■
■
Keep all inexperienced and unauthorized people clear of
the cutting area when operating the saw.
■
Always observe all applicable compulsory regulations
relevant to environmental protection, especially fuel storage,
the handling of hazardous substances, and the wearing of

MQ STREET PRO 1 CE SAW — GENERAL INFORMATION
Intended Use
Operate the SP1 Saw, tools and components in accordance
with the manufacturer's instructions. Use of any other tools for
stated operation is considered contrary to designated use. The
risk of such use lies entirely with the user. The manufacturer
cannot be held liable for damages as a result of misuse.
This saw is not intended for dry cutting.
General Information
The MQ Whiteman SP1 series
for
wet
cutting of
These saws have been engineered for general and industrial
flat sawing applications.The reinforced steel box frame design
adds strength necessary to reduce blade vibrations while cutting.
By minimizing blade vibrations the performance of the blade is
enhanced and thus the life of the blade is extended.
Heavy-duty front and rear axles, sturdy oversized wheels, and
industrial undercarriage assembly ensure accurate tracking and
years of reliable use.
Additionally, the general strength-to-weight ratio design of the
frame and chassis assembly provides for optimum weight
distribution to keep the blade running true in the cut. A rugged
spindle bearing assembly ensures minimal flutter and shaft
harmonics providing the most advantageous condition for a
diamond blade at operating speeds.
The SP1 series saw comes equipped with an 18-inch blade guard
and handles Diamond Blade ranging in size from 12-18-inches in
diameter.
An ACME thread, manual raise/lower assembly easily raises and
lowers the blade and locks it into position to ensure a constant depth
cut. All SP1 series saws are equipped with a retractable cutting
guide, oversized roller bearing wheels, industrial spindle bearings,
and a rigid steel frame.

are designed
Power Plants
The SP1 saw is classified in the industry as a "low" powered saw.
This classification is particularly useful when selecting the proper
diamond blade for an application.
The SP1 saw is powered by a HONDA GX390 air cooled, 4stroke, single cylnder, OHV gasoline engine rated at 13 HP (9.6
kW) at 3,600 RPM. Blade rotation is V-belt driven. The upper
drive (engine) pulley on the output shaft of the engine connects
to the lower drive (spindle) pulley and thus, the blade, by three
V-Belts. As the engine shaft rotates, so does the blade. The ratio, or
difference between the engine speed and the spindle (blade) speed
is determined by the two different sizes of pulleys used.
Refer to the
regarding engine operation and maintenance practices.
All MQ Whiteman SP1 series saws are designed, engineered
and manufactured with strict adherence to American National
Standards Institute, Inc. (ANSI) guidelines B7.1 and B7.5.
Water System
All SP1 series saws provide a hardy water plumbing system that
evenly distributes water volume and optimum flow rate to both
sides of the blade to keep it cool when cutting. The basic water
system provides a valve that connects to a standard garden hose.
The water is delivered (via a hose) to the saw blade. A water tank
delivery system is optional.

Guards And Covers
WARNING
NEVER operate the saw without blade
guards and covers in place. DO NOT
operate with the front of the blade guard
raised. The blade exposure cannot exceed
180 degrees during operation. Adhere to
the safety guidelines or other applicable
local regulations.
Figure 8. Blade Guard
V-belt Alignment and Tensioning
This saw is equipped with premium V-belts that have been
aligned and tensioned by factory personnel. The V-belt must be
aligned and tensioned for proper operation of the saw.
Use the following procedure to check the alignment of V-belt:
1. Remove the bolts that secure the V-belt cover (Figure 9) to
the saw frame.
Figure 9. V-Belt Cover
2. Check uniform parallelism (Figure 10) of V-belt and pulley
(sheaves). Use a straight-edge or machinist's square against
both pulleys and adjust both pulleys until equally aligned.
CHECK the following on the blade guard (Figure 8):
■
Ensure the capacity of the blade guard is correct for an 18"
Diamond Blade.
■
Check that the guard is bolted firmly upon the saw frame.
■
Check that the spring tensioned front cover of the guard is
firmly seated with the rear section of the guard and there are
no gaps. NEVER lift the blade guard while engine is running.
ENSURE the V-belt Cover is in place and securely fastened
during operation of the saw (Figure 8).
3. Check V-belt tension by using a tension meter (3.0 lbs./
V-Belt Check
A worn or damaged V-belt can adversely affect the performance
of the saw. If a V-belt is defective or worn, replace ALL the Vbelts. V-belts should always be replaced in sets.
4. DO NOT over or under tighten the V-belt. Severe damage

SPECIFIC TOOLS TO BE USED
1. Drive Pin Hole – A commonly located hole on the diamond
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. See Table 4 for specific
blade usage for material.
WARNING
Failure to thoroughly inspect the diamond blade (Figure 11)
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.

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.
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.

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 & 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.
