GENERAL SAFETY RULES
WARNING: The use of any cutoff machine can be dangerous. Because a cutoff
machine is a high-speed, fast-cutting power tool, special safety precautions must be
observed to reduce the risk of personal injury.
WARNING: Read and understand all instructions. Failure to follow all
instructions listed below may result in electric shock, fire and/or serious injury. Do not lend or
rent your cutoff saw without this manual.
WARNING: The warnings, cautions, and instructions discussed in this
instruction manual cannot cover all possible conditions or situations that could occur.
It must be understood by the operator that common sense and caution are factors which
cannot be built into this product, but must be supplied by the operator.
SAVE THESE INSTRUCTIONS.
WORK AREA
•Keep the work area clean, free of clutter and well lit. Cluttered and dark work areas
can cause accidents.
•Do not use your tool where there is a risk of causing a fire or an explosion; e.g.
in the presence of flammable liquids, gasses or dust. Power tools create sparks,
which may ignite the dust or fumes.
•Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control, so visitors should remain at a safe distance from the work
area.
•Be aware of all power lines, electrical circuits, water pipes and other mechanical
hazards in your work area, particularly those hazards below the work surface hidden
from the operator’s view that may be contacted unintentionally and may cause
personal harm or property damage.
•Be alert to your surroundings. Using power tools in confined work areas may put
you dangerously close to cutting tools and rotating parts.
INTERNAL COMBUSTION ENGINE SAFETY
WARNING: Only operate the engine in a well-ventilated area. Carbon Monoxide
produced by the engine during use can kill. Do not use indoors, near windows or in other
sheltered areas.
WARNING: Internal combustion engines present special hazards during
operation and fueling. Read and follow the warning instructions in the engine Owner’s
Manual and the safety guidelines below. Failure to follow the warnings and safety standards
could result in severe injury or death.
•DO NOT run the machine indoors or in an enclosed area such as a deep trench
3

unless adequate ventilation, through such items as exhaust fans or hoses, is
provided. Exhaust gas from the engine contains poisonous carbon monoxide gas;
exposure to carbon monoxide can cause loss of consciousness and may lead to
death.
•DO NOT smoke while operating the machine.
•DO NOT smoke when refueling the engine.
•DO NOT refuel a hot or running engine.
•DO NOT refuel the engine near an open flame.
•DO NOT spill fuel when refueling the engine.
•DO NOT run the engine near open flames.
•DO NOT modify or disengage safety devices.
•DO NOT operate the machine if any safety devices or guards are missing or
inoperative.
•DO NOT touch the engine or muffler while the engine is on or immediately after it
has been turned off. These areas get hot and may cause burns.
•ALWAYS refill the fuel tank in a well-ventilated area.
•ALWAYS replace the fuel tank cap after refueling.
•ALWAYS check the fuel lines and the fuel tank for leaks and cracks before starting
the engine. Do not run the machine if fuel leaks are present or the fuel lines are
loose.
•ALWAYS avoid contact with hot fuel, oil, exhaust fumes and solid surfaces.
•ALWAYS be sure that the operator is familiar with proper safety precautions and
operation techniques before using the machine.
•ALWAYS close the fuel valve when the machine is not being operated.
•ALWAYS operate the machine with all safety devices and guards in place and in
working order.
•ALWAYS avoid conditions that can create “kick-back”.
NOTE: All Federal and State laws and any regulation having jurisdiction covering the safety
requirements for use of the machine take precedence over the statements in this manual.
Users of this machine must adhere to such regulations.
PERSONAL SAFETY
•Stay alert. Watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence of
drugs, alcohol or medication. A moment of inattentiveness while operating power
tools may result in serious personal injury.
•Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep
your hair, clothing and gloves away from moving parts. Loose clothes, jewelry
and/or long hair can be caught in moving parts. Air vents often cover moving parts
and should be avoided.
•Use the proper safety apparel and equipment. Use safety goggles or safety
glasses with side shields which comply with current national standards, or when
needed, a face shield. Use as dust mask in dusty work conditions. This applies to
all persons in the work area. Also use non-skid safety shoes, a hardhat, gloves, a
dust collection system and hearing protection when appropriate.
•Avoid accidental starting. Do not carry the power tool with your finger on the
switch. Ensure the switch is in the off position before starting.
•Do not overreach. Keep your footing and balance at all times.

•Remove adjusting keys or wrenches before connecting the tool to the power
supply or turning it on. A wrench or key that is left attached to a rotating part of the
tool may result in personal injury.
TOOL USE AND CARE
•Do not force the tool. Tools do a better and safer job when used in the manner for
which they are designed. Plan your work, and use the correct tool for the job.
•Never use a tool with a malfunctioning on/off switch. Any power tool that cannot
be controlled with the switch is dangerous and must be repaired by an authorized
service professional before using.
•Disconnect spark plug from the tool and place the switch in the locked or off
position before servicing, adjusting, installing accessories or attachments or storing.
Such preventative safety measures reduce the risk of starting the power tool
accidentally.
•Secure your work with clamps or a vise instead of your hands when practical.
This safety precaution allows for proper tool operation using both hands.
•Use both hands to operate the saw.
•Always stop the engine and let the wheel come to a complete stop before putting
down or carrying the saw.
•This saw vibrates during use. Repeated or long-term exposure to vibration may
cause temporary or permanent physical injury, particularly to the hands, arms and
shoulders. Vary your time of operation.
•Make sure the Cutting Wheel's maximum operating speed is greater than the
maximum motor speed of 9500 RPM.
•Inspect the abrasive wheel frequently and replace immediately if cracked,
warped or showing other signs of wear.
•Never use circular saw blades,carbide-tipped blades, rescue blades, wood cutting
blades or toothed blades with this saw.
•Store idle tools. When tools are not is use, store them in a dry, secure place out
of the reach of children. Inspect the tools for good working condition prior to
storage and before re-use.
•Use only manufacturer-recommended accessories for your model. Accessories
that may be suitable for one tool may cause injury when used on another tool.
•Do not store the Cut-off Saw with the Blade installed.
•Keep all guards in place and in working order.
•Never leave the tool unattended when running.
