information on pages 17 and 19.
WARNINGWARNING
WARNING
WARNINGWARNING
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. All damaged blades must be
discarded.
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.
■
ALWAYS store equipment properly when it is not being used.
Equipment should be stored in a clean, dry location out of
the reach of children.
■
ALWAYS keep the work area well organized.
■
ALWAYS Clear the cutting area of any debris, tools, etc. that
would constitute a hazard while the saw is in operation.
WARNINGWARNING
WARNING
WARNINGWARNING
ALWAYS check to make sure that the
operating area is clear before starting the
engine.
■
No one other than the operator is to be in the working area
when the saw is in operation.
■
Always observe all applicable compulsory regulations
relevant to environmental protection, especially, fuel storage,
the handling of hazardous substances, and the wearing of

WARNINGWARNING
WARNING
WARNINGWARNING
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 regulate 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.
Ensure that the blade is mounted for proper operating
direction. (See Figure 4, page 13)
Adhere to the Blade Manufacturer's recommendations on
handling, storage, and safe usage of blades.

MQ SP2 CE SAW — GENERAL INFORMATION
Intended Use
Operate the SP2 CE 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.
Power Plants
The SP2 CE saw is classified in the industry as a "low to medium"
powered saw. This classification is particularly useful when selecting
the proper diamond blade for an application.
There are two gasoline engines used with the SP2 CE series
saws: A
single cylinder, OVH rated at 3600 RPM and a
GX620TXF2
General Information
The MQ Whiteman SP2 CE series

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 SP2 CE series saw comes equipped with a 20-inch blade
guard and handles Diamond Blades™ ranging in size from 12-20inches in diameter.
A threaded, manual raise/lower assembly easily raises and lowers
the blade and locks it into position to ensure a constant depth cut. All
SP2 CE series saws are equipped with a retractable cutting guide,
oversized roller bearing wheels, industrial spindle bearings, and a
rigid steel frame.

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
regarding engine operation and maintenance practices.
All MQ Whiteman SP2 CE 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 SP2 CE 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.

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. All blades must be designed to
