PROPOSITION 65 WARNING
Engine exhaust and some of
its constituents, and some dust created
by power sanding, sawing, grinding,
drilling and other construction activities
contains chemicals known to the State
of California to cause cancer, birth
defects and other reproductive harm.
Some examples of these chemicals are:
Lead from lead-based paints.
Crystalline silica from bricks.
Cement and other masonry products.
Arsenic and chromium from chemically
treated lumber.
Di-lsononyl Phthalate (DINP)
Your risk from these exposures varies,
depending on how often you do this type
of work. To reduce your exposure to
these chemicals: ALWAYS work in a
well ventilated area, and work with
approved safety equipment, such as
dust masks that are specially designed
to filter out microscopic particles.

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.
MP2 SERIES MASONRY SAW • OPERATION MANUAL — REV. #3 (10/17/17) — PAGE 3
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.

GENERAL INFORMATION
MP2 MASONRY SAW
The MP2 Masonry Saw is designed for vigorous wet-cutting
masonry applications. The heavy-duty steel conveyor cart
and ball bearing roller wheels ensure material stability and
smooth travel. In addition a reinforced jig-welded steel frame
provides rigidity for cutting accuracy and long service life.
This saw is available with either an electric motor or a
gasoline engine. Two heavy duty electric motors are
available: a 5 HP 230V single phase or 5 HP 230V three
phase, all with overload protection.
If desired, the MP2 Masonry Saw can be configured with
an 8.5 HP Honda GX270 gasoline engine.
All MP2 saw models include a high flow water pump, cutting
jig, water hoses and associated plumbing to enable the
operator to begin wet cutting.
WET CUTTING APPLICATIONS
For operator safety, ALL sawing must be conducted with
the water delivery system that is provided with the masonry
saw. Ensure that a free flow of clean water is properly routed
from the pump through the plumbing system so that the
blade receives an ample amount of water. This action is
required to safeguard against the operational hazards of
silica exposure.
BLADE APPLICATIONS
This saw has been designed to incorporate the use
of diamond blades as the cutting tool. The optimum
performance of this saw is best evidenced by using 20-inch
(508 mm) diamond blades that match the material being
cut. Ask your dealer, or call MULTIQUIP about your specific
cutting application.
FEATURES
5 HP, 230 VAC , 60 Hz heavy duty electric motors with
overload protection.
8.5 HP Honda GX270 gasoline engine.
20-inch blade capacity provides 8-inch depth of cut.
Rugged steel conveyor cart for optimum stability.
Open back design permits capability of cutting large
materials.
Ergonomically designed cutting head provides operator
relief in high tempo operations.
Welded fork pockets for easy transportation.
Rubber-matted cutting table helps hold the material
being cut in place while resisting vibrations for smoother
cuts with less chipping.
WARNING
Adherence to the OSHA 2017 Ruling governing
Occupational Exposure to Respirable Crystalline
Silica, requires that all sawing operations MUST BE
conducted with an integrated water delivery system
that feeds water to the blade.
Cutting table marked in inches (ruler) for precision cuts.
Stay-level blade guard for operator safety.
Rigid steel frame minimizes vibrations and assures
accurate cutting.
