PAGE 18 — SP118 PAVEMENT SAW • OPERATION MANUAL — REV. #1 (05/03/12)
GENERAL INFORMATION
INTENDED USE
Operate the SP118 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.
GENERAL INFORMATION
The MQ SP118 Saws are designed for wet or dry 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.
This saw comes equipped with an 18-inch blade guard and
handles Diamond Blades ranging in size from 12-18-inches
in diameter.

POWER PLANTS
The SP118 saw is generally considered a "low" powered
saw in the industry. This classification is particularly
useful when selecting the proper diamond blade for an
application.
This SP118 saw is powered by a HONDA GX390U1QWT2
air cooled, 4-stroke, single cylnder, OHV gasoline engine
rated at 11 HP (8.2 kW) at 3,600 RPM.
Refer to the HONDA Engine Owner's Manual for specific
information regarding engine operation and maintenance
procedures.
BLADE ROTATION
Three premium 3VX belts connecting a properly sized drive
(engine) pulley and an output blade shaft pulley provides
the rotational power of the diamond blade. Specific pulley
diameters have been chosen to support the design of the
SP118 saw.
Ultimate blade shaft RPM speed is very important for the
safe, efficient operation of the diamond blade in the cut.
All SP118 SAWS are designed, engineered and
manufactured with strict adherence to American
National Standards Institute, Inc. (ANSI) guidelines
B7.1 and B7.5.
