Protect yourself and others from injury — read and follow these precautions.

1-1. Symbol Usage

DANGER! − Indicates a hazardous situation which, if

not avoided, will result in death or serious injury. The

possible hazards are shown in the adjoining symbols

or explained in the text.

Indicates a hazardous situation which, if not avoided,

could result in death or serious injury. The possible

hazards are shown in the adjoining symbols or ex-

plained in the text.

NOTICE − Indicates statements not related to personal injury.

. Indicates special instructions.

This group of symbols means Warning! Watch Out! ELECTRIC

SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult sym-

bols and related instructions below for necessary actions to avoid the

hazards.

1-2. Hazards

The symbols shown below are used throughout this manual

to call attention to and identify possible hazards. When you

see the symbol, watch out, and follow the related instructions

to avoid the hazard. The safety information given below is

only a summary of the more complete safety information

found in the Safety Standards listed in Section 1-5. Read and

follow all Safety Standards.

Only qualified persons should install, operate, maintain, and

repair this unit.

During operation, keep everybody, especially children, away.

ELECTRIC SHOCK can kill.

Touching live electrical parts can cause fatal shocks

or severe burns. The input power circuit and machine

internal circuits are live when power is on.

D Do not touch live electrical parts.

D Do not use equipment in damp areas, if movement is confined, or if

there is a danger of falling.

D Additional safety precautions are required when any of the follow-

ing electrically hazardous conditions are present: in damp

locations or while wearing wet clothing; on metal structures such

as floors, gratings, or scaffolds; when in cramped positions such

as sitting, kneeling, or lying; or when there is a high risk of unavoid-

able or accidental contact with the equipment. And, do not work

alone!

D Disconnect input power before installing or servicing this equip-

ment.

D Properly install and ground this equipment according to its

Owner’s Manual and national, state, and local codes.

D Always verify the supply ground − check and be sure that input

power cord ground wire is properly connected to ground terminal in

disconnect box or that cord plug is connected to a properly

grounded receptacle outlet.

D Do not touch grounded surfaces when using this equipment (metal

pipes, enclosures, structures, etc.).

D When making input connections, attach proper grounding conduc-

tor first − double-check connections.

D Keep cords dry, free of oil and grease, and protected from hot metal

and sparks.

D Frequently inspect input power cord for damage or bare wiring −

replace cord immediately if damaged − bare wiring can kill.

D Turn off all equipment when not in use. Do not leave equipment

until it has completely stopped.

D Use only well-maintained equipment. Repair or replace damaged

parts at once. Maintain unit according to manual.

D Keep all panels and covers securely in place.

HOT PARTS can burn.

D Do not touch hot parts bare handed.

D Allow cooling period before working on equip-

ment.

D To handle hot parts, use proper tools and/or

wear heavy, insulated welding gloves and

clothing to prevent burns.

Using this equipment with certain materials may

produce fumes, gases, and particles. Breathing

these fumes, gases, and particles can be hazardous

to your health.

FUMES, GASES, AND PARTICLES can

be hazardous.

D Keep your head out of the fumes, gases, and particles. Do not

breathe the fumes, gases, and particles.

D If inside, ventilate the area and/or use local forced ventilation to re-

move fumes, gases and particles.

D If ventilation is poor, wear an approved air-supplied respirator.

D Read and understand the Material Safety Data Sheets (MSDSs)

and the manufacturer’s instructions for metals, consumables,

coatings, cleaners, and degreasers.

D Work in a confined space only if it is well ventilated, or while

wearing an air-supplied respirator. Always have a trained watch-

person nearby. Fumes, gases, and particles can displace air and

lower the oxygen level causing injury or death. Be sure the breath-

ing air is safe.

D Do not work in locations near degreasing, cleaning, or spraying

operations.

D Do not work on materials that may contain hazardous substances,

including masonry, treated lumber, and items with lead-based

paint. Do not work on on coated metals, such as galvanized, lead,

or cadmium plated steel, unless the coating is removed from the

work area, the area is well ventilated, and while wearing an air-

supplied respirator. Coatings and any materials containing these

elements can give off toxic fumes, gases, and particles when

worked on.

OM-254 206 Page 2

Sparks can fly off from the equipment. The flying

sparks, hot workpiece, and hot equipment can

cause fires and burns. Accidental contact with metal

objects can cause sparks, explosion, overheating,

or fire. Check and be sure the area is safe before doing any work.

SPARKS can cause fire or explosion.

D Remove all flammables within 35 ft (10.7 m) of the equipment. If

this is not possible, tightly cover them with approved covers.

D Do not work where flying sparks can strike flammable material.

D Protect yourself and others from flying sparks and hot metal.

D Be alert that sparks and hot materials can easily go through small

cracks and openings to adjacent areas.

D Watch for fire, and keep a fire extinguisher nearby.

D Do not work where the atmosphere may contain flammable dust,

gas, or liquid vapors (such as gasoline).

D Wear oil-free protective garments such as a heavy shirt, cuffless

trousers, high shoes, and a cap.

D Remove any combustibles, such as a butane lighter or matches,

from your person before doing any work.

D After completion of work, inspect area to ensure it is free of sparks,

glowing embers, and flames.

D Use only correct fuses or circuit breakers. Do not oversize or by-

pass them.

D Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B

for hot work and have a fire watcher and extinguisher nearby.

FLYING METAL or DIRT can injure eyes.

D Welding, chipping, wire brushing, and grinding

cause sparks and flying metal. As welds cool,

they can throw off slag.

D Wear approved safety glasses with side

shields even under your welding helmet.

NOISE can damage hearing.

Noise from some processes or equipment can

damage hearing.

D Wear approved ear protection if noise level is

high.

1-3. Additional Symbols For Installation, Operation, And Maintenance

FIRE OR EXPLOSION hazard.

D Do not install or place unit on, over, or near

combustible surfaces.

D Do not install unit near flammables.

D Do not overload building wiring − be sure power supply system is

properly sized, rated, and protected to handle this unit.

FALLING EQUIPMENT can injure.

D Use equipment of adequate capacity to lift and

support unit.

D Keep equipment (cables and cords) away from

moving vehicles when working from an aerial

location.

D Do not stand on the equipment.

D If applicable, bolt equipment to a smooth surface large and

strong enough to safely support it.

D Follow the guidelines in the Applications Manual for the Revised

NIOSH Lifting Equation (Publication No. 94−110) when manu-

ally lifting heavy parts or equipment.

FLYING SPARKS can injure.

D Wear a face shield to protect eyes and face.

D Operate equipment with proper guards, and in

a safe location while wearing proper face, and

body protection.

MOVING PARTS can injure.

D Keep away from moving parts.

D Keep all doors, panels, covers, and guards

closed and securely in place.

D Have only qualified persons remove doors, panels, covers, or

guards for maintenance and troubleshooting as necessary.

D Reinstall doors, panels, covers, or guards when maintenance is

finished and before reconnecting input power.

D Do not wear clothing, gloves, or jewelry, or other items that may

be caught in moving parts. Wear a hat or other covering to con-

tain long hair.

D Do not make adjustments on moving equipment. Remove ad-

justing tools (keys, wrenches) before using equipment.
