WORK AREA

• Keep your work area clean and well lit, Cluttered

benches and dark areas invite _cc;dents.

• Do not operate power tools in explosive stmo-

spheres, such as in the presence of flammable liq-

uids, gases, or dust. Power tools create sparkswhich

may ignitethe dustor fumes,

•Keep bystanders, children, andvbltore eweywblls

operating a power tool. Distractionscan cause you to

lose control.

ELECTRICAL SAFETY

•Double Insulated tools are equipped with a polar-

ized plug (one blade is wider than the other). This

plug wi(I fit in a polarized out(st only one way. If the

plug does not fit fully in the outlet, reverse the plug.

If it still does not fit, contact • qualified eleoVldan

to install e polarized out(eL Do nat change the plug

in any way. Double insulation[] eliminatesthe need

for the three-wire grounded power cord and grounded

power supplysystem.

•Avoid body contact wlth grounded surfaces such

as pipes, radiators, range_, and rstrlperatore. There

Is an Increasedriskof electricshock Ifyour body Is

grounded.

•Don't expose power tools to rein or wet conditions`

Water enteringapower tool will Increase the riskof

erectricshock.

•Do nat abuse the cord. Never use the cord to carry

the tools or pull the plug from an outlet. Keep cord

away from heat, oil, sharp edges, or moving parts.

Replace damaged cords immediately. Damaged

cords increasethe risk of electricshock.

•When operating s power tool outside, use an outdoor

exterBIon cord marked '=W-A"or =If_. Thesecords

are ratedfor outdooruseand reducethe riskof electric

shock.

PERSONAL SAFETY

•Stay alert, watch what you are doing and use com-

men sense when operating s power tool. Do not

invitesaccidents.

•Remove adjusting keys or wrenches before tuming

the tool on. A wrench or a key that is leftattached to a

rotating part of the toolmay resultin persocaJiniury.

•Do not overreach. Keep proper footing end balance

at all times. Properfooting and balance en_b[asbetter

TOOL USE AND CARE

•Use clamps or other practical way to secure and

support the workplece to a stable platform. Holding

the work by hand oragainst your body is unstableand

may lead to lossof centroL

•Do not force too/. Use the correct tool for your ap-

plication. The correct too(will do the job better and

setar at the rate tor which it is designed.

•Do not cee tool if =witch does not turn it on or off.

Anytool that cannot be controlledwith the switchis

dangerousand must be repaired.

•Disconnect the plug from power source before

making any adjustments, changing accessories,

or storing the tool. Such preventivesafety measures

reduce the riskof startingthe tool accidentally.

•Store idle tools out of the reach of children and

other untrained persona. Tootsare dangerousinthe

hands of untrainedusers.

•Mdntsln tools wtth cars. Keep cuffing tools sharp

and clean. Properlymaintainedtoolswith sharp cut-

ting edges are less likelyto bind and are easierto

control

•Check for misaitgnment or binding of moving parts,

brsekags of parts, and any othe_ condition that

may effect the tool's operation. If damaged, have

the tool serviced before using. Many accidents are

caused by poorly maintained tools.

•Use only accessories that are recommended by the

manufacturer for your model. Accessoriesthat may

DOUBLE INSULATION

Double insulationis a concept insafety in electricpower

tools, which eliminates the need for the usualthres-wlre

grounded power cord. AJiexposed metal partsare

isolatedfrom the internalmetal motor componentswith

protectinginsulation.Double insulatedtools do not need

to be grounded.

WARNING: The double insulated systemis

intended to pmteot the userfrom shook resulting

from abreak in the tool's internalinsulation.Observe

NOTE: Servicingof a tool withdouble insulationrequires

extreme care and knowledge of the systemand should

be performedonly by a qualified servicetechnician. For

service,we suggestyou return the tool to your nearest

authorrzed servicecenterfor repair.A_vaysuse original

faotory replacementpartswhen servicing.

ELECTRICAL CONNECTION

This tool has aprecLsion-builtslectYicmotor,Itshould be

connectedto a power supply that Is 120 volts, 60 Hz,

AC only (normal household current). Do not operate

this tool on directcurrent (DC). A substantialvoltage drop

will cause a loss of power and the motor will overheat.If

yourtool does not operate when plugged into an outlet,

double-check the power suppry.

EXTENSION CORDS

When usinga power tool at a considerabledistance from

a power soume, be sureto use an extensioncord that has

the capacity to handle the currentthe tootwill draw. An

undersizedcordwill cause adrop in tinsvoltage,resulting

inoverheatingand lose of power,Use the ohartto deter-

SANDPAPER SELECTION

Selectingthe correct size gritand type sandpaper is

an extremelyimportantstep inachievinga highquality

sanded finish.Aluminumoxide,siliconcarbide, and other

syntheticabrsaivea are bestfor power sanding. Natural

abrasivessuchas flint and gernetare too solt for eco-

nomicaluse in power sanding.In genera[,coarse grit will

remove the most material and finer grit will produce the

best _nish in allsanding operations.The conditionof the

surfaceto be sanded will determinewhich gritwill do the

job. If the surfaceis rough,start with a coarsegrit and

sand untilthe surface Is uniform.Medium grit may then

be usedto removescratchesleft by the coarser grit a,'_d

finer grit usedfor finishingof the surface.Alwayscontinue

sanding with each grit untilsurfaceis uniform.

NOTE: Do not use sanderwithout sandpaper. Doing so

will damage the cushion.
