GASOLINE / PROPANE POWERED EQUIPMENT
• Engine exhaust from this product contains chemicals
known to the State of California to cause cancer, birth
defects or other reproductive harm.
• Tilting a gasoline powered machine tted with an
EPA approved vented charcoal lter gas cap, beyond
20° can cause fuel leakage. If a leak occurs, do not
start or run the engine until the leak is xed. Eliminate all other ignition
sources in the immediate area (no smoking, ares, sparks or ames).
Use approved gasoline absorbing material to contain the fuel leakage.
Then use clean, non-sparking tools to collect absorbed materials then
dispose of these contaminants properly.
• Gasoline is extremely ammable and poisonous. It should
only be dispensed in well ventilated areas, and with a cool
engine.
• Small gasoline engines produce high concentrations of
carbon monoxide (CO) example: a 5 HP 4 cycle engine operation in
an enclosed 100,000 cu. ft. area with only one change of air per hour
is capable of providing deadly concentrations of CO in less than fteen
minutes. Five changes of air in the same area will produce noxious
fumes in less than 30 minutes. Gasoline powered equipment should
not be used in enclosed or partially enclosed areas. Symptoms of CO
poisoning include, head-ache, nausea, weakness, dizziness, visual
problems and loss of consciousness. If symptoms occur - get into
fresh air and seek medical attention immediately.
• Never refuel a hot engine or an engine while it is running.
• Engines are shipped from factory without fuel/oil.
a poorly ventilated area where leaking propane gas could accumulate
and endanger safety of persons in area. If headache develops, shut o
machine. Have it checked for carbon monoxide emissions by a qualied
technician before using it again. To ensure personal safety, installation
and repair of propane fuel supply systems must be performed only by
qualied technicians. Carbon monoxide emissions from this machine are
greatly increased due to a dirty combustion air cleaner.
• Propane is extremely ammable and is heavier than air
and tends to settle in low areas where a spark or ame could
ignite gas. DO NOT start or operate this propane engine in
ELECTRICAL POWERED EQUIPMENT
Extreme care must be taken when operating electric models
with water present: Ensure power cord is properly grounded,
is attached to a Ground-Fault-Interrupter (GFI) outlet, and is
undamaged.
• Check all electrical cables - be sure connections are tight and cable
is continuous and in good condition. Be sure cable is correctly rated
for both the operating current and voltage of this equipment.
• Improper connection of the equipment grounding conductor can
result in a risk of electric shock. Check with qualied electrician or
service person if there is any doubt as to whether the outlet is properly
grounded. Adhere to all local codes and ordinances.
• NOTE: In the event of a malfunction or breakdown, grounding provides
a path of least resistance for the electric current to dissipate. The motor
is equipped with a grounded plug and must be connected to an outlet
that is properly installed and properly grounded. DO NOT modify the
plug provided on the motor. If the plug does not t the outlet have a
qualied electrician install the proper receptacle.

ELECTRICAL POWERED EQUIPMENT CONTINUED
• Do not disconnect power by pulling cord. To disconnect, grasp the
plug, not the cord.
• Unplug power cord at the machine when not in use and before servicing.
• Switch motor OFF before disconnecting power.
• Never use frayed, damaged, taped or under rated extension cords.
Electrical shock could result in death or serious injury to the operator
and damage to the equipment.
• Assure you are using the proper extension cord length.
GENERAL INSTRUCTIONS
• Equipment should only be operated by trained personnel in good
physical condition and mental health (not fatigued). The operator and
maintenance personnel must be physically able to handle the bulk
weight and power of this equipment.
• This is a one person tool. Maintain a safe operating distance to other
personnel. It is the operators’ responsibility to keep other people (work-
ers, pedestrians, bystanders, etc.) away during operation. Block o
the work area in all directions with roping, safety netting, etc.
Failure to do so may result in others being injured by ying debris or
exposing them to harmful dust and noise.
• This equipment is intended for commercial use only.
• For the operator ’s safety and the safety of others, always keep all
guards in place during operation.
• Never let equipment run unattended.
• Personal Protection Equipment and proper safety attire must be worn
when operating this machinery. The operator must wear approved
safety equipment appropriate for the job such as hard hat and safety
shoes when conditions require. Hearing protection MUST be used
when operational noise levels of this equipment may exceed 85db.
Eye protection MUST be worn at all times.
Keep body parts, loose clothing and accessories away from
moving parts. Failure to do so could result in dismemberment
or death.
• Do not modify the machine.
• Stop motor/engine when adjusting or servicing this equipment. Maintain
a safe operating distance from ammable materials. Sparks
from the cutting-action of this machine can ignite ammable
materials or vapors.
DUST WARNING
Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemi-
cals known to cause cancer, birth defects, or other
reproductive harm. Materials being removed can be toxic or hazardous.
A breathing respirator is required to help protect the operator.
Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, concrete and other
masonry products.Your risk of exposure to these chemi cals varies de-
pending on how often you do this type of work. To reduce your risk: work
in a well ventilated area, use a dust control system, such as an industrialstyle vacuum, and wear approved personal safety equipment, such as a
dust/particle respirator designed to lter out microscopic particles.

Safety Guidelines
Eye and ear protection must be worn at all times while the grinder is in use. During normal operation,
sound pressure levels may exceed 85dBA. Use only ANSI approved safety glasses to help prevent
eye injury. Everyday eyeglasses have only impact resistant lenses; they are NOT safety glasses.
Operator must wear appropriate clothing and footwear. Do not wear loose clothing or jewelry that
can get tangled in moving parts. Footwear should provide sure footing and protection.
• Inspect the work surface for cracks, uneven joints and foreign objects such as nails, screws and pipes. Damage
to the disc and/or equipment may result which can also cause serious injury to the operator. Hazardous areas
should be properly identied and clearly marked.
• The TMC-7 is designed to be controlled by a single operator .
• Inspect the discs carefully before installing. Do not use any questionable disc since serious personal injury and/
or damage to property can result.
• Never operate this grinder while under the inuence of drugs, alcohol or when taking medications that impair the
senses or reactions, or when excessively tired or under stress.
• Be sure decals on the machine can be clearly read and understood. Replace worn or missing decals immediately,
Safety warnings and guidelines do not by themselves eliminate danger.
