SAFETY
MESSAGES

• Safety Instructions are proceeded by a graphic alert symbol

of DANGER, WARNING, or CAUTION.

GASOLINE/PROPANE POWERED EQUIPMENT

harm.

• Gasoline is extremely ammable and poisonous. It

• Small gasoline engines produce high concentrations of car-

bon monoxide (CO) example: a 5 HP 4 cycle engine opera­ tion 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 min­ utes. Gasoline or propane powered equipment should not be
used in enclosed or partially enclosed areas. Symptoms of
CO poisoning include, headache, nausea, weakness, dizzi­ ness, visual problems and loss of consciousness. If symp­ toms occur - get into fresh air and seek medical attention
immediately.

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 qualied electri-

cian 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 machine 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 qualied

electrician install the proper receptacle.

• Switch motor OFF before disconnecting power.

should only be dispensed in well ventilated areas,
and with a cool engine.

• Do not disconnect power by pulling cord. To disconnect, grasp
the plug, not the cord.

servicing.

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 (workers, pedestrians, bystanders, etc.) away
during operation. Block off the work area in all directions with
roping, safety netting, etc. for a safe distance. 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 (operational noise levels of this
equipment may exceed 85db). Eye protection MUST be worn
at all times.

Keep body parts and loose clothing 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 chemicals known to cause cancer,
birth defects, or other reproductive harm. Some
examples of these chemicals are:

• Lead from lead-based paints, and

• Crystalline silica from bricks and concrete and other

masonry products.
Your risk of exposure to these chemicals varies depending

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 industrial-style 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.

Materials being removed can be toxic or hazardous. A breathing respirator is required to help protect the oper­ator from inhaling the airborne material when operating this machine.

• 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 identied and clearly marked.

• The SEC-NG 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 inuence 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.

They are not given as substitutes for proper accident prevention procedures and good judgement.
