general power tool Safety warnings

warning read all safety warnings and instructions.

Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term ″power tool″ in the warnings refers to your corded power tool.

1. work area safety a. Keep work area clean and well lit.

Cluttered or dark areas invite accidents.

b. do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids,

gases or dust. Power tools create sparks which may ignite the dust or fumes.

c. Keep children and bystanders away while operating a power tool.

Distractions can cause you to lose control.

2. electrical safety a. 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.

For technical questions, please call 1-800-444-3353. Page 2

b. do not expose power tools to rain

or wet conditions. Water entering a power tool will increase the risk of electric shock.

c. do not abuse the cord. never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp

edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

d. when operating a power tool outdoors, use an extension cord suit-

able for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

e. if operating a power tool in a damp location is unavoidable, use a ground Fault circuit interrupter

(gFci) protected supply. Use of a GFCI reduces the risk of electric shock.

3. personal safety a. 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 inattention while operating power tools may result in serious personal injury.

b. use personal protective equip-

ment. always wear eye protection.

Safety equipment such as welding mask, non-skid safety shoes, and welding apron used for appropriate conditions will reduce personal injuries.

c. prevent unintentional starting. ensure the switch of the stick welder is in the off-position before connecting to power source, picking

up or carrying the tool. d. do not overreach. Keep proper

footing and balance at all times.

This enables better control of the power tool in unexpected situations.

e. dress properly. do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away

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

f. only use safety equipment that has been approved by an appropri-

ate standards agency. Unapproved safety equipment may not provide adequate protection. Eye protection must be ANSI-approved and breathing protection must be NIOSH-approved for the specific hazards in the work area.

4. power tool use and care a. do not force the power tool. use the correct power tool for your ap-

plication. The correct power tool will do the job better and safer at the rate for which it was designed.

b. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to oper-

ate the power tool. Power tools are dangerous in the hands of untrained users.

c. maintain power tools. check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. if damaged, have the power tool repaired

before use. Many accidents are

SKU 98759 For technical questions, please call 1-800-444-3353. Page 3

caused by poorly maintained power tools.

d. use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions

and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

5. Service a. Have your power tool serviced by a qualified repair person using only identical replacement parts.

This will ensure that the safety of the power tool is maintained.

WARNING: The brass components of this product contain lead, a chemi­ cal known to the State of California to cause birth defects (or other repro­ ductive harm). (California Health &

Safety code § 25249.5, et seq.)

Some dust created by power sand­ ing, sawing, grinding, drilling, and other construction activities, contains chemicals known [to the State of Cali­ fornia] to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints

• Crystalline silica from bricks and ce­ ment or other masonry products

• Arsenic and chromium from chemi­ cally treated lumber

Your risk from these exposures var­ ies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. (California Health & Safety

Code § 25249.5, et seq.)

Prevent accidental fires.

Remove any combustible material from the work area. Move flammable and explosive material at least 35 feet from the welding arc to prevent welding sparks or mol ten metal from starting a fire. Keep a type

ABC fire extinguisher within easy reach. Thoroughly clean the object being welded of any paint, grease, or other foreign material.

If working on a wall or ceiling prevent ignition of combustibles on the other side by moving them to a safe loca­ tion.

Industrial applications must follow

OSHA guidelines. Follow OSHA guidelines for Permis sible Exposure

Limits (PEL’s) for vari ous fumes and gases.

Prevent eye injury and burns. Wearing and using

ANSI­approved personal safety clothing and safety devices reduce the risk for injury.

Leather leggings, fire resistant shoes or boots should be worn when using this product. Do not wear pants with cuffs, shirts with open pockets, or any clothing that can catch and hold molten metal or sparks.

Keep clothing and work surfaces free of grease, oil, solvents, or any flammable substances. Wear dry, insulat­ ing gloves and protective clothing.
