MQ STREET PRO 1 CE SAW — GENERAL INFORMATION
The MQ Whiteman SP1 series
walk-behind saws
are designed
for
wet
cutting of
concrete
or
asphalt
utilizing Diamond Blades.
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.
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.
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, 4-
stroke, 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
Engine Owner's Manual
for specific instructions
regarding engine operation and maintenance practices.
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.
