PROPOSITION 65 WARNING

Engine exhaust and some of

its constituents, and some dust created

of California to cause cancer, birth

defects and other reproductive harm.

by power sanding, sawing, grinding,

drillingandotherconstructionactivities

contains chemicals known to the State

Some examples of these chemicals are:

Leadfromlead-basedpaints.

Crystallinesilicafrombricks.

Cementandothermasonryproducts.

Arsenicandchromiumfromchemically

treatedlumber.

Di-lsononyl Phthalate(DINP)

Your risk from these exposures varies,

dependingonhowoftenyoudothistype

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.

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

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.Inaddition, 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.

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.

SAFETY INFORMATION

GENERAL SAFETY

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.

CAUTION



NEVER operate this equipment without proper protective

clothing, shatterproof glasses, respiratory protection,

hearing protection, steel-toed boots and other protective

devices required by the job or city and state regulations.



Avoid wearing jewelry or loose ﬁtting clothes that may

snag on the controls or moving parts as this can cause

serious injury.



NEVER operate this equipment when not

feeling well due to fatigue, illness or when

under medication.



NEVER operate this equipment under the

inﬂuence of drugs or alcohol.



ALWAYS clear the work area of any debris, tools, etc.

that would constitute a hazard while the equipment is

in operation.

No one other than the operator is to be in the working

area when the equipment is in operation.

ALWAYS

check the equipment for loosened threads or

bolts before starting.

DO NOT

use the equipment for any purpose other than

its intended purposes or applications.

SAFETY INFORMATION

SAW SAFETY

DANGER



NEVER operate the equipment in an explosive atmosphere

or near combustible materials. An explosion or ﬁre could

result causing severe bodily harm or even death.

WARNING



Accidental starting can cause severe injury

or death. ALWAYS place the ON/OFF

switch in the OFF position.



Keep hands away from moving parts at all

times.



NEVER disconnect any emergency

or safety devices. These devices are

intended for operator safety. Disconnection of these

devices can cause severe injury, bodily harm or even

death. Disconnection of any of these devices will void

all warranties.

CAUTION



ALWAYS ensure saw is securely placed on appropriate

blocks or jackstands when maintenance requires

elevation of the saw.



If the machine malfunctions, stop the saw immediately

and secure it. Fix the problem as soon as possible.

NOTICE



ALWAYS keep the machine in proper running condition.



Fix damage to machine and replace any broken parts

immediately.



Make sure there is no buildup of grease, oil or debris

on the machine.



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 and unauthorized personnel.

BLADE SAFETY

WARNING



Rotating blade can cut and crush. ALWAYS

keep hands and feet clear while operating

the saw.

CAUTION

NEVER operate the saw without blade

guards and covers in place. Exposure of

the diamond blade must not exceed 180

degrees.



Verify the motor start switch is set to the OFF position

before installing a blade.

ALWAYS inspect blade 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.

NOTICE



Use proper blades and follow blade manufacturer’s

recommendations. Match the blade RPM (blade shaft

RPM) to the recommended blade surface feet per minute

(SFPM).



Ensure the blade-mounting bolt is tightened

adequately

ALWAYS

examine blade flanges for damage and

excessive wear.



Ensure the blade is marked with an operating speed

greater than the spindle speed of the saw.



Only cut the material that is speciﬁed for the diamond

blade. Read the speciﬁcation of the diamond blade to

ensure the proper tool has been matched to the material

being cut.



Ensure that water is used during sawing operations and

that a sufﬁcient ﬂow of water is applied to both sides of

the blade.

DO NOT

drop the diamond blade on ground or surface.



Ensure that the blade is mounted for proper operating

direction.



Adhere to the blade manufacturer’s recommendations

on handling, storage and safe usage of blades.

SAFETY INFORMATION

ELECTRIC MOTOR SAFETY

NOTICE



Operate electric motor only at the speciﬁed voltage

indicated on the nameplate.



DO NOT spray water onto electric motor.



ALWAYS disconnect AC power plug from power source

before moving saw, changing blade, or performing

maintenance.



ALWAYS make sure the ON/OFF switch

on the electric motor is in the OFF position

when not in use and before inserting the

saw’s power plug into an AC receptacle.

Power Cord/Cable Safety

DANGER



NEVER let power cords or cables lay in water.



NEVER use damaged or worn cables or cords when

connecting equipment to generator. Inspect for cuts in

the insulation.



NEVER grab or touch a live power

cord or cable with wet hands. The

possibility exists of electrical shock,

electrocution or death.



Make sure power cables are securely

connected. Incorrect connections may

cause electrical shock and damage to the

saw.

CAUTION



Ensure that cables and cords will not be tripped over or

trapped underneath the saw.



Never use the cable to pull out the plug from the power

source.

NOTICE



ALWAYS make certain that proper power or extension

cord has been selected for the job.



Protect the cable from heat, oil, and sharp edges.
