General Power Tool Safety

Warnings

WARNING Read all safety

warnings and instructions.

Failure to follow the warnings and

instructions may result in electric

shock, re and/or serious injury.

Save all warnings and

instructions for future reference.

The term ″power tool″ in the

warnings refers to your mains-

operated (corded) power tool or

battery-operated (cordless) power

tool.

Work area safety1.

Keep work area clean and well lit.a.

Cluttered or dark areas invite acci-

dents.

doors, use an extension cord suit-

able for outdoor use. Use of a cord

suitable for outdoor use reduces the

risk of electric shock.

If operating a power tool in a dampf. location is unavoidable, use a

Ground Fault Circuit Interrupter

(GFCI) protected supply. Use of

a GFCI reduces the risk of electric

shock.

Personal safety3.

Stay alert, watch what you are do-a.

ing and use common sense when

operating a power tool. Do not use

a power tool while you are tired

or under the inuence of drugs,

alcohol or medication. A moment

of inattention while operating power

tools may result in serious personal

injury.

Use personal protective equip-b.

ment. Always wear eye protection.

Safety equipment such as dust mask,

non-skid safety shoes, hard hat, or

hearing protection used for appropri-

ate conditions will reduce personal

injuries.

Prevent unintentional starting.c.Ensure the switch is in the off-po-

sition before connecting to power

source and/or battery pack, pick-

ing up or carrying the tool. Carry-

ing power tools with your nger on

the switch or energizing power tools

that have the switch on invites acci-

dents.

Remove any adjusting key ord.

wrench before turning the power

tool on. A wrench or a key left at-

tached to a rotating part of the power

tool may result in personal injury.

Do not overreach. Keep propere.

footing and balance at all times.

This enables better control of the

power tool in unexpected situations.

Dress properly. Do not wear loosef. 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.

If devices are provided for the con-g.

nection of dust extraction and col-

lection facilities, ensure these are

connected and properly used. Use

of these devices can reduce dust-

related hazards.

Only use safety equipment thath.

has been approved by an appropri-

ate standards agency. Unapproved

safety equipment may not provide

adequate protection. Eye protection

must be ANSI-approved and breath-

ing protection must be NIOSH-ap-

proved for the specic hazards in the

work area.

Power tool use and care4.

Do not force the power tool. Usea.

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.

Do not use the power tool if theb.

switch does not turn it on and off.

Any power tool that cannot be con-

trolled with the switch is dangerous

and must be repaired.

Disconnect the plug from thec.power source and/or the battery

pack from the power tool before

making any adjustments, chang-

ing accessories, or storing power

tools. Such preventive safety mea-

sures reduce the risk of starting the

power tool accidentally.

Store idle power tools out of thed.

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.

Maintain power tools. Check fore.

misalignment or binding of moving

parts, breakage of parts and any

other condition that may affect the

power tool’s operation. If dam-

aged, have the power tool repaired

before use. Many accidents are

caused by poorly maintained power

tools.

Keep cutting tools sharp andf. clean. Properly maintained cutting

tools with sharp cutting edges are

less likely to bind and are easier to

control.

Use the power tool, accessoriesg.

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 differ-

ent from those intended could result

in a hazardous situation.

Service6.

hearing loss.

Use auxiliary handles supplied2. with the tool. Loss of control can

cause personal injury.

Hold power tools by insulated grip-3. ping surfaces when performing an

operation where the cutting tool

may contact hidden wiring or its

own cord. Contact with a ″live″ wire

will make exposed metal parts of the

tool ″live″ and shock the operator.

Maintain labels and nameplates on4. the tool. These carry important safety

information. If unreadable or miss-

ing, contact Harbor Freight Tools for a

replacement.

Avoid unintentional starting. Prepare5. to begin work before turning on the

GROUNDING

TO PREVENT

ELECTRIC SHOCK

AND DEATH FROM

INCORRECT GROUNDING

WIRE CONNECTION:

Check with a qualied

electrician if you are in doubt

as to whether the outlet is

properly grounded. Do not

modify the power cord plug

provided with the tool. Never

remove the grounding prong

from the plug. Do not use the

tool if the power cord or plug

is damaged. If damaged, have

it repaired by a service facility

before use. If the plug will not

t the outlet, have a proper

outlet installed by a qualied

electrician.

Grounded Tools: Tools with Three

Prong Plugs

Tools marked with “Grounding Re-1. quired” have a three wire cord and

three prong grounding plug. The

plug must be connected to a properly

grounded outlet. If the tool should

electrically malfunction or break

down, grounding provides a low

resistance path to carry electricity

away from the user, reducing the risk

Page 7SKU 98179 For technical questions, please call 1-800-444-3353.

of electric shock. (See 3-Prong Plug

and Outlet.)

The grounding prong in the plug is2. connected through the green wire in-

side the cord to the grounding system

in the tool. The green wire in the cord

must be the only wire connected to

the tool’s grounding system and must

never be attached to an electrically

“live” terminal. (See 3-Prong Plug

and Outlet.)

The tool must be plugged into an3. appropriate outlet, properly installed

and grounded in accordance with all

codes and ordinances. The plug and

outlet should look like those in the

preceding illustration. (See 3-Prong

Plug and Outlet.)

Double Insulated Tools: Tools

with Two Prong Plugs

Tools marked “Double Insulated” do1. not require grounding. They have

a special double insulation system

tories, Inc., the Canadian Standard

Association, and the National Electri-

cal Code. (See Outlets for 2-Prong

Plug.)

Double insulated tools may be used2. in either of the 120 volt outlets shown

in the preceding illustration. (See

Outlets for 2-Prong Plug.)

Extension Cords

Grounded1. tools require a three wire

extension cord. Double Insulated

tools can use either a two or three

wire extension cord.

As the distance from the supply outlet2. increases, you must use a heavier

gauge extension cord. Using exten-

sion cords with inadequately sized

wire causes a serious drop in voltage,

resulting in loss of power and pos-

sible tool damage.

(See Table A.) The smaller the

gauge number of the wire, the greater

the capacity of the cord. For ex-

ample, a 14 gauge cord can carry a

higher current than a 16 gauge cord.

(See Table A.)

When using more than one exten-3. sion cord to make up the total length,

make sure each cord contains at

least the minimum wire size required.

(See Table A.)

If you are using one extension cord4. for more than one tool, add the

nameplate amperes and use the sum

to determine the required minimum

cord size. (See Table A.)

If you are using an extension cord5. outdoors, make sure it is marked with
