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 specic 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

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 breathe 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 and OSHA
regarding the appropriate respiratory protection.

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 KEEP WORK AREA CLEAN. DO NOT RUN OVER
ANYTHING
Loose objects could be thrown from crack. Make sure area to be cut is
clear from people and any loose objects, nuts, bolts, etc. Never run over
any loose objects
1.11 KEEP CHILDREN AND VISITORS AWAY
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.
1.12 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.
1.13 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
proper hand protection.

During normal operation as instructed in Section 6.0, keep a rm hold on
the handle grips and maintain control of the machine until the blade
completely stops.
1.15 CHECK BLADE AND MACHINE ROTATION
DIRECTION
Never operate a blade in the wrong rotation direction. Check the machine
rotation direction and blade direction when mounting a blade.
1.16 CHECK BLADE MAXIMUM ALLOWABLE SPEED
Check the maximum operating speed of the machine and blade. Never use
a blade rated less than the machine’s maximum speed rating.
1.17 CHECK BLADE FOR CRACKS, DAMAGE, AND
MISALIGNMENT
Never use a cracked, damaged, or misaligned blade. After mounting blade,
rotate by hand to check for proper alignment.
1.18 CHECK DIAMOND BLADE FOR WARNINGS

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.

1.19 DO NOT FORCE WRONG SIZE OR TYPE BLADE
ONTO MACHINE
Do not force a blade onto the machine shaft or alter the size of the arbor
mounting hole. Be certain that the drive pin is in place through the blade
when tightening the blade nut. Never add a drive pin hole or modify a
blade.
1.20 USE CORRECT SAW AND ACCESSORIES
Do not force a small saw to do the job of a heavy-duty saw. Do not use the
saw for improper applications. Never cut material for which the blade was
not designed. Check blade manufacturer’s guidelines on material to be
cut.

The machine, blades and tools should be stored in a dry and secure loca-
tion when not in use. Keep equipment out of reach of children.
1.22 DO NOT FORCE SAW
The saw will do the job better and safer at the rate for which it was
designed.
1.23 OBTAIN MATERIAL SAFETY DATA SHEET (MSDS)
FOR ALL WORK SURFACE MATERIALS
This includes primers, all coatings, adhesives, tile and crack lling materi-
als, etc. Do not attempt to cut, clean out or remove material without MSDS

Verify all machine guards are in good condition and will function properly
before using the machine. Check for alignment of moving parts, binding of
moving parts, breakage of parts, mounting, and any other conditions that
may a󰀨ect machine operation. A guard, power switch or other part that is
damaged should be properly repaired or replaced by an authorized service
center unless indicated elsewhere in this instruction manual. Do not oper-
ate machine if lever or engine on/o󰀨 switch does not function properly.
1.31 SECURELY MOUNT ACCESSORIES AND BLADES
TO THE MACHINE
Extra care must be taken when using saws on an elevated location to pre-
vent injury to someone on a lower level in the event the tool or accessory
should drop. Do not operate without fall protection for operator and debris
protection for public.
1.32 NEVER TOUCH THE MOVING PARTS
Never touch moving parts such as blades, belts and others.
1.33 STOP OPERATION IMMEDIATELY IF ANY

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 (a󰀨ecting 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;
nWear 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.
