1.1 KNOW THE RULES & YOUR EQUIPMENT
Most Job sites have rules governing equipment use & maintenance.
Before starting at a new work location, check with the supervisor or
safety coordinator. Ask about any rules or regulations you need to
abide.
OSHA enforces federal laws within the United States that apply to the
safe operation, application, & maintenance of equipment on job sites.
It is the employer’s responsibility to comply with these laws.
Do not operate this machine unless you have read the operations and
maintenance manual carefully. Read any additional instructions included
from other manufacturers and organizations and the Masonry and
Concrete Saw Manufacturers Institute. Learn the applications and limita-
tions as well as the specic potential hazards related to this tool.
1.2 RECEIVE PROPER TRAINING
Do not operate this machine unless you have received operational and
maintenance training from a DiamaPro Systems® representative or from
an authorized distributor for DiamaPro Systems®.
1.3 PROTECT YOUR FEET
Observe all applicable local, state and federal safety regulations. Wear
OSHA approved foot protection.
1.4 PROTECT YOUR EYES
Observe all applicable local, state and federal safety regulations. Wear
OSHA approved safety glasses.
1.5 PROTECT YOUR LUNGS
Breathable silica may be generated by use of this product. Silica can
cause severe and permanent lung damage, cancer, and other serious
diseases. Do not breath the dust. Do not rely on your sight or smell to
determine if the dust is in the air. Silica may be in the air without a visible
dust cloud. If air monitoring equipment for silica is not provided by your
employer at your work site, you MUST wear appropriate respiratory
protection when using or servicing the machine. If dry cutting, be sure to
use a HEPA ltered dust collector. Consult your employer

Do not wear loose clothing or jewelry that can be caught in moving parts.
Wear protective hair covering to contain long hair. Keep hair away from
motor air vent. Rubber gloves and non-skid footwear are recommended
when working outdoors.
1.8 AVOID A DANGEROUS ENVIRONMENT
Do not expose machine to rain. Do not use machine in wet conditions.
Keep work area well lit. When working at an elevated location, pay atten-
tion to articles and persons below.
1.9 BEWARE OF HIDDEN DANGERS IN CONCRETE
Rebar or utility lines may be buried in concrete. Disconnect the power to
any utility lines. If these items are to be missed, clearly mark the area. If
these items are to be cut, check the blade manufacturer’s guidelines on
material to be cut.
1.10 AVOID ANY AREAS OR ACTIONS THAT EXPOSE
YOU TO CARBON MONOXIDE
Exhaust gas from gasoline engines contains dangerous carbon monoxide.
Breathing it can cause unconsciousness and even kill you. Always operate
gasoline engine machines in a well-ventilated area. Do not operate in
areas where exhaust fumes could accumulate without wearing appropriate
respiratory protection. Consult your employer and OSHA regarding use of
appropriate respirator for dangerous carbon monoxide gases.

Do not allow anyone to stand in line with the blade path. Do not let children
or visitors contact machine or extension cord. Keep children and visitors
away from the work area.
1.13 AVOID FLAMMABLE LIQUIDS OR GASES
Engines and diamond blades produce heat and sparks during operation.
Never use machines in dangerous sites containing ammable, combustible
or explosive materials such as lacquer, paint, benzene, thinner, gasoline,
gases, and adhesive agents.
1.14 AVOID CONTACT WITH HOT BLADE AND BLADE
GUARD
The blade and blade guard become hot during operation and remain hot
after stopping the engine. Do not touch the blade and blade guard without

blade, rotate by hand to check for proper alignment.
1.19 CHECK DIAMOND BLADE FOR WARNINGS
Many diamond blades contain a chemical known to the state of California
to cause cancer and/or birth defects or other reproductive harm. Diamond
blades improperly used are dangerous. Comply with American National
Standards Institute Safety Code B71 and Occupational Safety & Health
Act covering SPEED, SAFETY GUARDS, FLANGES, MOUNTING PRO-
CEDURES, GENERAL OPERATING RULES, HANDLING, STORAGE&
INSPECTION AND GENERAL MACHINE CONDITIONS. Read Diamond
Blades Safety Manual before use.

DUST WARNING
Cutting, especially when DRY cutting, generates dust that comes from the material being cut, which
frequently contains silica. When dry cutting, be sure to use a HEPA ltered dust collector.
Silica is a basic component of sand, quartz, brick clay, granite and numerous other minerals and rocks. Exposure to
excessive amount of such dust can cause:
n Respiratory diseases (aecting your ability to breath), including chronic bronchitis, silicosis and pulmonary brosis
from exposure to silica. These diseases may be fatal;
nSkin irritation and rash; and
nCancer according to NTP* and IARC*
*National Toxicology Program, International Agency for Research on Cancer
Take precautionary steps
nAvoid inhalation of and skin contact with dust, mist and fumes;
nWet cut when feasible, to minimize dust;
n Wear and ensure that all bystanders wear appropriate respiratory protection such as dust masks designed to lter
out microscopic particles. (See OSHA 29 CFR Part 1910.1200)
California Prop 65 Warning: Use of this product can cause exposure to materials known to the State of California
to cause cancer and/or birth defects or other reproductive harm.
