SAFETY INSTRUCTIONS
4.1 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.
4.2 RECEIVE PROPER TRAINING.
Do not operate this machine unless you have received operational and
maintenance training from a U.S. SAWS representative or from an autho-
rized distributor for U.S.SAWS.

Observe all applicable local, state and federal safety regulations. Wear
OSHA approved foot protection.
4.4 PROTECT YOUR EYES.
Observe all applicable local, state and federal safety regulations. Wear
OSHA approved safety glasses.
4.5 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 vis-
ible 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. Consult your employer
and OSHA regarding the appropriate respiratory protection.
4.6 PROTECT YOUR HEARING.
Observe all applicable local, state and federal safety regulations. Wear
OSHA approved hearing protection.
4.7 DRESS PROPERLY.
Do not wear loose clothing or jewelry that can be caught in moving parts.

4.9 ELECTRICAL SAFETY
Power tool plugs must match the outlet. Never modify the plug in any way.
Do not use any adapter plugs with earthed (grounded) power tools. Unmodi-
ed plugs and matching outlets will reduce risk of electric shock.
Avoid body contact with earthed or grounded surfaces such as pipes, radia-
tors, ranges and refrigerators. There is an increased risk of electric shock if
your body is earthed or grounded.
4.10 ELECTRICAL CORD MANAGEMENT
Do not abuse the cord. Never use the cord for carrying, pulling or unplug-
ging the power tool. Keep cord away from heat, oil, sharp edges or moving
parts. Damaged or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
4.11 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 oper-
ate 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.
4.12 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.
4.13 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.
4.14 KEEP FIRM GRIP ON MACHINE.
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.

DUST WARNING
Cutting, especially when DRY cutting, generates dust that comes
from the material being cut, which frequently contains silica.
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:
• Respiratory diseases (affecting your ability to breath), including
chronic bronchitis, silicosis and pulmonary brosis from exposure
to silica. These diseases may be fatal;
• Skin irritation and rash; and
• Cancer according to NTP* and IARC*
* National Toxicology Program, International Agency for Research
on Cancer
Take precautionary steps
• Avoid inhalation of and skin contact with dust, mist and fumes;
• Wet cut when feasible, to minimize dust;
• 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.
