1. 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.

2. 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.

3. Store idle tools out of reach of children and other 

untrained persons.

 Tools are dangerous in the hands of 

untrained users.

4. Maintain tools with care. Keep cutting tools maintained 

and clean.

 Properly maintained tools are less likely to bind 

and are easier to control. Do not use a damaged tool. Tag 

damaged tools “Do not use” until repaired

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 1. before using.

 Many accidents are caused by 

poorly maintained tools.

2. 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

1. Tool service must be performed only by qualified 

repair personnel. Service or maintenance performed by 

unqualified personnel could result in a risk of injury.
When servicing a tool, use only identical replacement parts. 

Use of unauthorized parts or failure to follow maintenance 

instructions may create a risk of electric shock or injury

SPECIFIC SAFETY RULES

1. Maintain labels and nameplates on the tool.

 These carry 

important information. If unreadable or missing, contact 

TOOLEX INDUSTRIAL for a replacement.

2. Always wear the approved safety impact eye goggles 

and heavy work gloves when suing the tool.

 Using 

personal safety devices reduce the risk for injury. Safety 

impact eye goggles and heavy work gloves are available 

from Harbor Freight Tools.

3. Maintain a safe working environment.

 Keep the work 

area well lit. Make sure there is adequate surrounding 

workspace. Always keep the work area free of obstructions, 

grease, oil, trash, and other debris. Do not use a power tool 

in areas near flammable chemicals, dusts, and vapors.  

Do not use this product in a damp or wet location.

1. Avoid unintentional starting. 

Make sure you are prepared 

to begin work before turning on the tool.

2. Never leave the tool unattended when it is plugged into 

an electrical outlet.

 Turn off the tool, and unplug it from its 

electrical outlet before leaving.

3. Always unplug the tool from its electrical outlet before 

performing and inspection, maintenance, or cleaning 

procedures.
4. Prevent eye injury and burns. 

Wearing and using the 

approved personal safety clothing and safety devices 

reduce the risk for injury.

a. Wear the approved safety impact eye goggles with a 

welding helmet featuring at least a number 10 shade lens 

rating.
b. 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.
c. Keep clothing free of grease, oil, solvents, or any 

flammable substances. Wear dry, insulating gloves and 

protective clothing.
d. Wear an approved head covering to protect the head 

and neck. Use aprons, cape, sleeves, shoulder covers, 

and bibs designed and approved for welding and cutting 

procedures.
e. When welding/cutting overhead or in confined spaces, 

wear flame resistant ear plugs or ear muffs to keep sparks 

out of ears.
1. Prevent accidental fires. Remove any combustible 

material from the work area.
When possible, move the work to a. 

a location well 

away from combustible; protect the combustibles with a 

cover made of fire resistant material.
b. Remove or make safe all combustible materials for a 

radius of 35 feet (10 meters) around the work area. Use a 

fire resistant material to cover or block all open doorways, 

windows, cracks, and other openings.
c. Enclose the work area with portable fire resistant 

screens. Protect combustible walls, ceilings, floors, etc., 

from sparks and heat with fire resistant covers.
d. If working on a metal wall, ceiling, etc., prevent 

ignition of combustibles on the other side by mobbing 

the combustibles to a safe location. If relocation of 

combustibles is not possible, designate someone to serve 

as a fire watch, equipped with a fire extinguisher, during 

the welding process and for at least one half hour after the 

welding is completed.
a. Do not weld or cut on materials having a combustible 

coating or combustible internal structure, as in walls or 

ceilings, without an approved method for eliminating the 

hazard.
b. Do not dispose of hot slag in containers holding 

combustible materials. Keep a fire extinguisher nearby and 

know how to use it.
After welding or cutting, make a thorough examination for 

evidence of fire. Be aware that easily visible smoke or flame 

may not be present for some time after the fire has started. 

Do not weld or cut in atmospheres containing 
a. Dangerously reactive or flammable gases, vapors, liquids, 

and dust.
b. Provide adequate ventilation in work areas to prevent 

accumulation of flammable gases, vapors, and dust. Do 

not apply heat to a container that has held an unknown 

substance or a combustible material whose contents, when 

heated, can produce flammable or explosive vapors. Clean 

and purge containers before applying heat. Vent closed 

containers, including castings, before preheating, welding, 

or cutting.
