Engine exhaust and some of
its constituents, and some dust created
by power sanding, sawing, grinding,
drillingandotherconstructionactivities
contains chemicals known to the State
of California to cause cancer, birth
defects and other reproductive harm.
Some examples of these chemicals are:
Leadfromlead-basedpaints.
Crystallinesilicafrombricks.
Cementandothermasonryproducts.
Arsenicandchromiumfromchemically
treatedlumber.
Your risk from these exposures varies,
dependingonhowoftenyoudothistype
of work. To reduce your exposure to
these chemicals: work in aALWAYS
well ventilated area, and work with
approved safety equipment, such as
dust masks that are specially designed
to filter out microscopic particles.

FOR YOUR SAFETY AND THE SAFETY OF OTHERS!
Safety precautions should be followed at all times when
operating this equipment. Failure to read and understand
the Safety Messages and Operating Instructions could result
in injury to yourself and others.
This Owner's Manual has
been developed to provide
NOTE
For engine maintenance information, please refer to the
engine manufacturers instructions for data relative to its safe
operation.
Before using this MASONRY SAW, ensure that the
operating individual has read and understands all
instructions in this manual.
SAFETY MESSAGE ALERT SYMBOLS
complete instructions for the
safe and efficient operation of
the MP2 Masonry Saw.
HAZARD SYMBOLS
Potential hazards associated with operation of the pump will
be referenced with Hazard Symbols which appear throughout
this manual, and will be referenced in conjunction with Safety
Message Alert Symbols. Some examples are listed below:
WARNING - Guards and Covers In Place
WARNING - Rotating Blade
NEVER operate the saw without blade
guards and covers in place. Adhere to
safety guidelines ANSI American
National Standards Institute, OSHA or
other applicable local regulations.
Rotating blade can cut and crush.
Keep hands and feet clear.
The three (3) Safety Messages shown below will inform you

MP2 MASONRY SAW — SAFETY MESSAGE ALERT SYMBOLS
WARNING - Accidental Engine Starting
ALWAYS place the engine ON/
OFF switch in the OFF position,
when the saw is not in use.
WARNING - Over Speed Conditions
NEVER tamper with the factory
settings of the engine governor or
settings. Personal injury and damage
to the engine or equipment can result
if operating in speed ranges above
maximum allowable.
CAUTION - Respiratory Hazard
ALWAYS wear approved respiratory
protection that complies with ANSIZ87.1.
CAUTION - Sight and Hearing Hazards
HAZARD SYMBOLS - Gasoline Powered Models
WARNING - Lethal Exhaust Gases
Engine exhaust gases contain
poisonous carbon monoxide. This
gas is colorless and odorless, and
can cause death if inhaled. NEVER
operate this equipment in a confined
area or enclosed structure that does
not provide ample free flow air.
WARNING - Explosive Fuel
Gasoline is extremely flammable, and
its vapors can cause an explosion if
ignited. DO NOT start the engine near
spilled fuel or combustible fluids. DO
NOT fill the fuel tank while the engine
is running or hot.
DO NOT overfill tank, since spilled fuel could ignite if
it comes into contact with hot engine parts or sparks
from the ignition system. Store fuel in approved
containers, in well-ventilated areas and away from
sparks and flames. NEVER use fuel as a cleaning
agent.
ALWAYS wear approved eye and
hearing protection that complies
with ANSI-Z87.1
CAUTION - Equipment Damage Messages
Other important messages are provided throughout this
manual to help prevent damage to your concrete saw,
other property, or the surrounding environment.

compliance with all local electrical codes. This must be
performed by a
■
ALWAYS use only outdoor approved GROUNDED
extension cords.
■
MAKE CERTAIN the power cord/extension cord is free
from damage and that the grounding circuit is operational.
■
MAKE CERTAIN the extension cord used is intended to
be used in the environment you will be using it in. If an
extension is used, NEVER submerge the connection in
water. To reduce the risk of electrical shock, always make
water-tight connections.
■
MAKE CERTAIN the "ON/OFF" switch is in the "OFF"
position before plugging in the power cord/extension cord
to avoid accidental starting.
■
ALWAYS stop the motor before servicing. MAKE
CERTAIN the motor is stopped and turned "OFF" at the
switch, and the power cord is disconnected from the
power source.
■
Use only the guage wire and length of cord recommended
for the motor size.
■
When cutting, ALWAYS be aware of the location of the
cord.
General Safety
■
ALWAYS read, understand, and follow procedures in
Operator's Manual before attempting to operate
equipment.
■
ALWAYS be sure the operator is familiar with proper
safety precautions and operating techniques before using
the saw.
■
NEVER leave the machine
■
Block the unit when leaving or when using on a slope.
■
ALWAYS check to make sure that the operating area is
clear before starting the engine.
■
Maintain this equipment in a safe operating condition at
all times.

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.
NEVER use accessories or attachments which are not
recommended by the manufacturer for this equipment.
Damage to the equipment and/or injury to user may result.
WARNING - Clear Area Of Obstructions
ALWAYS check to make sure that the
operating area is clear before starting the
engine.
Use appropriate blades manufactured for use on masonry
saws.
Always inspect 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, excessive wear and
cleanliness before mounting blade. 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 blade shaft speed of the saw.
Only cut the material that is specified by the blade. Read
the specifications of the blade to ensure the proper tool
has been matched to the material being cut.
Always keep blade guards in place.
Exposure of the blade must not
exceed 180 degrees.
NEVER touch or try to stop a
moving blade with your hands.
ALWAYS keep hands clear of the
blade.

■
Ensure that the blade does not come into contact with the
ground or surface during transportation. DO NOT drop the
blade on ground or surface.
■
The engine governor is designed to permit maximum engine
speed in a no-load condition. Speeds that exceed this limit
may cause the blade to exceed the maximum safe allowable
speed.
■
Ensure that the blade is mounted for proper operating
direction.

Saw Maintenance (Cleaning)
■
ALWAYS clean the saw before maintenance or repair.
■
DO NOT use aggressive cleaners (i.e. containing solvents).
DO NOT use high pressure water jets, aggressive detergents
or solutions and liquids with a temperature exceeding 86 F.
Use a fluff-free cloth only.
■
Use a cloth which may be lightly moistened only for removing
dust and dirt. Hard packed dirt can be removed with a
brush.
■
NEVER let water, cleaning liquid or vapor penetrate into the
electric motor, connectors, plugs, and switches. When
cleaning cover all apertures or openings on all electrical
components.
