3. Keep bystanders, children, and visitors away while operating a power tool.

Distractions can cause you to lose control. Protect others in the work area from

debris such as chips and sparks. Provide barriers or shields as needed.

ELECTRICAL SAFETY

4. Grounded tools must be plugged into an outlet properly installed and

grounded in accordance with all codes and ordinances. Never remove the

grounding prong or modify the plug in any way. Do not use any adapter

plugs. Check with a qualified electrician if you are in doubt as to whether

the outlet is properly grounded. If the tools should electrically malfunction or

break down, grounding provides a low resistance path to carry electricity away

from the user.

5. Avoid body contact with grounded surfaces such as pipes, radiators,

ranges, and refrigerators. There is an increased risk of electric shock if your

body is grounded.

6. Do not expose power tools to rain or wet conditions. Water entering a power

tool will increase the risk of electric shock.

7. Do not abuse the Power Cord. Never use the Power Cord to carry the tools

or pull the Plug from an outlet. Keep the Power Cord away from heat, oil,

sharp edges, or moving parts. Replace damaged Power Cords immedi-

ately. Damaged Power Cords increase the risk of electric shock.

8. When operating a power tool outside, use an outdoor extension cord

marked “W-A” or “W”. These extension cords are rated for outdoor use, and

reduce the risk of electric shock.

PERSONAL SAFETY

9. Stay alert. Watch what you are doing, and use common sense when oper-

ating a power tool. Do not use a power tool while tired or under the influ-

ence of drugs, alcohol, or medication. A moment of inattention while operat-

ing power tools may result in serious personal injury.

SKU 90648 PAGE 3

10. Dress properly. Do not wear loose clothing or jewelry. Contain long hair.

Keep your hair, clothing, and gloves away from moving parts. Loose

clothes, jewelry, or long hair can be caught in moving parts.

90648.p65 12/1/2003, 10:56 AM3

11. Avoid accidental starting. Be sure the Power Switch is off before plugging

in. Carrying power tools with your finger on the Power Switch, or plugging in

power tools with the Power Switch on, invites accidents.

12. Remove adjusting keys or wrenches before turning the power tool on. A

wrench or a key that is left attached to a rotating part of the power tool may result

in personal injury.

13. Do not overreach. Keep proper footing and balance at all times. Proper

footing and balance enables better control of the power tool in unexpected

situations.

14. Use safety equipment. Always wear eye protection. Make sure you are

wearing your protective clothing, ANSI approved safety glasses with side shields,

air respirator, and welding helmet.

TOOL USE AND CARE

15. Use clamps (not included) or other practical ways to secure and support

the workpiece to a stable platform. Holding the work by hand or against your

body is unstable and may lead to loss of control.

16. Do not force the tool. Use the correct tool for your application. The correct

tool will do the job better and safer at the rate for which it is designed.

17. Do not use the power tool if the Power Switch does not turn it on or off.

Any tool that cannot be controlled with the Power Switch is dangerous and must

be replaced.

18. Disconnect the Power Cord Plug from the power source before making any

adjustments, changing accessories, or storing the tool. Such preventive

safety measures reduce the risk of starting the tool accidentally.

19. Store idle tools out of reach of children and other untrained persons. Tools

are dangerous in the hands of untrained users.

20. Maintain tools with care. Keep all components of the Torch clean and dry.

Do not use a damaged tool. Tag damaged tools “Do not use” until repaired.

SKU 90648 PAGE 4

21. Check for misalignment or binding of moving parts, breakage of parts, and

any other condition that may affect the tool’s operation. If damaged, have

the tool serviced before using. Many accidents are caused by poorly main-

tained tools.

90648.p65 12/1/2003, 10:56 AM4

22. Use only accessories that are recommended by the manufacturer for your

model. Accessories that may be suitable for one tool may become hazardous

when used on another tool.

SERVICE

23. Tool service must be performed only by qualified repair personnel. Service

or maintenance performed by unqualified personnel could result in a risk of injury.

24. When servicing a tool, use only identical replacement parts. Follow

instructions in the

“Inspection, Maintenance, And Cleaning”

section of this

manual. Use of unauthorized parts or failure to follow maintenance instructions

may create a risk of electric shock or injury.

GROUNDING

SKU 90648 PAGE 5

1. WARNING! The Power Cord (11) requires the attachment of a 220 volt,

grounded, 3-Prong Plug (not included). For safety purposes, only a qualified,

certified, electrician should attach a Plug to the Power Cord. Never modify the

Plug in any way. To comply with the National Electric Code, and to provide

additional protection from the risk of electrical shock, this product should only be

connected to a 220 volt electrical outlet that is protected by a Ground Fault Cir-

cuit Interrupter (GFCI).

2. Do not use the tool if the Power Cord or Plug is damaged. If damaged,

have it repaired by a qualified service facility before use.

EXTENSION CORDS

Grounded

tools require a three wire extension cord.

2. As the distance from the supply outlet increases, you must use a heavier

gauge extension cord. Using extension cords with inadequately sized wire

causes a serious drop in voltage, resulting in loss of power and possible tool

damage. (See Figure A, next page.)

90648.p65 12/1/2003, 10:56 AM5

SKU 90648 PAGE 6

3. The smaller the gauge number of the wire, the greater the capacity of the

cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge

cord. (See Figure A.)

4. If using more than one extension cord to make up the total length, make

sure each cord contains at least the minimum wire size required.

(See Figure A.)

5. If you are using one extension cord for more than one tool, add the name-

plate amperes and use the sum to determine the required minimum cord

size. (See Figure A.)

6. If you are using an extension cord outdoors, make sure it is marked with

the suffix “W-A”(“W” in Canada) to indicate it is acceptable for outdoor

use.

7. Make sure your extension cord is properly wired and in good electrical

condition. Always replace a damaged extension cord or have it repaired by a

qualified electrician before using it.

8. Protect your extension cords from sharp objects, excessive heat, and

damp or wet areas.
