FURTHERSAFETYINSTRUCTIONSFORALL
OPERATIONSKickbackandRelated
Warnings
Kickbackisasuddenreactiontoapinchedor
snaggedrotatingwheel,backingpad,brushorany
otheraccessory.Pinchingorsnaggingcausesrapid
stallingoftherotatingaccessorywhichinturn
causestheuncontrolledpowertooltobeforcedin
thedirectionoppositeoftheaccessory’srotationat
thepointofthebinding.
Forexample,ifanabrasivewheelissnaggedor
pinchedbytheworkpiece,theedgeofthewheel
thatisenteringintothepinchpointcandigintothe
surfaceofthematerialcausingthewheeltoclimb
outorkickout.Thewheelmayeitherjumptoward
orawayfromtheoperator,dependingondirection
ofthewheel’smovementatthepointofpinching.
Abrasivewheelsmayalsobreakunderthese
conditions.
Kickbackistheresultofpowertoolmisuseand/or
incorrectoperatingproceduresorconditionsand
canbeavoidedbytakingproperprecautionsas
givenbelow.
a. Maintainafirmgriponthepowertooland
positionyourbodyandarmtoallowyouto
resistkickbackforces.Alwaysuseauxiliary
handle,ifprovided,formaximumcontrolover
kickbackortorquereactionduringstart‐up.
Theoperatorcancontroltorquereactionsor
kickbackforces,ifproperprecautionsare
taken.
b. Neverplaceyourhandneartherotating
accessory.Accessorymaykickbackoveryour
hand.

7
c. Donotpositionyourbodyintheareawhere
powertoolwillmoveifkickbackoccurs.
Kickbackwillpropelthetoolindirection
oppositetothewheel’smovementatthepoint
ofsnagging.
d. Usespecialcarewhenworkingcorners,sharp
edgesetc.Avoidbouncingandsnaggingthe
accessory.Corners,sharpedgesorbouncing
haveatendencytosnagtherotatingaccessory
andcauselossofcontrolorkickback.
e. Donotattachasawchainwoodcarvingblade
ortoothedsawblade.Suchbladescreate
frequentkickbackandlossofcontrol.
ADDITIONALSAFETYINSTRUCTIONS
FORGRINDINGANDCUTTING‐OFF
OPERATIONS
SafetyWarningsSpecificforGrindingandAbrasive
Cutting‐OffOperations:
a. Useonlywheeltypesthatarerecommended
foryourpowertoolandthespecificguard
designedfortheselectedwheel.Wheelsfor
whichthepowertoolwasnotdesignedcannot
beadequatelyguardedandareunsafe.
b. Theguardmustbesecurelyattachedtothe
powertoolandpositionedformaximum
safety,sotheleastamountofwheelis
exposedtowardstheoperator.Theguard
helpstoprotecttheoperatorfrombroken
wheelfragments,accidentalcontactwith
wheelandsparksthatcouldigniteclothing.
c. Wheelsmustbeusedonlyforrecommended
applications.Forexample:donotgrindwith
thesideofcut‐offwheel.Abrasivecut‐off
wheelsareintendedforperipheralgrinding,
sideforcesappliedtothesewheelsmaycause
themtoshatter.
d. Alwaysuseundamagedwheelflangesthatare
ofcorrectsizeandshapeforyourselected
wheel.Properwheelflangessupportthewheel
thusreducingthepossibilityofwheel
breakage.Flangesforcutoffwheelsmaybe
differentfromgrindingwheelflanges.
e. Donotuseworndownwheelsfromlarger
powertools.Wheelintendedforlargerpower
toolisnotsuitableforthehigherspeedofa
smallertoolandmayburst.
ADDITIONALSAFETYWARNINGSSPECIFIC
FORABRASIVECUTTINGOFF
OPERATIONS:
a. Do not “jam” the cut‐off wheel or apply
excessivepressure.Donotattempttomakean
excessivedepthofcut.  Overstressing  the
wheelincreasestheloadingandsusceptibility
totwistingorbindingofthewheelinthecutand
thepossibilityofkickbackorwheelbreakage.
b. Donotpositionyourbodyinlinewithand
behindtherotatingwheel.Whenthewheel,
atthepointofoperation,ismovingaway
fromyourbody,thepossiblekickbackmay
propelthespinningwheelandthepowertool
directlyatyou.
c. Whenwheelisbindingorwheninterrupting
acutforanyreason,switchoffthepower
toolandholdthepowertoolmotionlessuntil
the wheel comes to a complete stop.Never
attempttoremovethecut‐offwheelfrom
thecutwhilethewheelisinmotion
otherwisekickbackmayoccur.Investigateand
takecorrectiveactiontoeliminatethecause
ofwheelbinding.
d. Donotrestartthecuttingoperationinthe
workpiece.Letthewheelreachfullspeedand
carefullyreenterthecut.Thewheelmaybind,

throughthemotorwhilerunningatnoloadtoclean
outaccumulateddust.(Ifoperatinginespecially
dustyconditions,performthisoperationmore
often.)
KEEPTOOLCLEAN
Periodicallyblowoutallairpassageswithdry
compressedair.Allplasticpartsshouldbecleaned
withasoftdampcloth.NEVERusesolventstoclean
plasticparts.Theycouldpossiblydissolveor
otherwisedamagethematerial.Wearsafety
glasseswhileusingcompressedair.
THECARBONBRUSHES
Thecarbonbrushesareanormalwearingpartand
mustbereplacedwhentheyreachtheirwearlimit.
NOTE:Checkingandreplacingthecarbonbrushes
shouldbeentrustedtoaqualifiedservicecenter.
Thecarbonbrushesfurnishedwilllastapproximately
50hoursofrunningtimeor10,000on/offcycles.
Replacebothcarbonbrusheswheneitherhasless
than1/4"lengthofcarbonremaining.Toinspector
replacebrushes,firstunplugthemachineandlayit
onitsside.Toinspectorreplacebrushes,first
unplugthemachine.Carefullyremovethe4screws
toseparatetherearhandlehalvesandthenremove
the4screwswhichconnectthehandletothemotor
housing.Liftawaytheleft‐handhandlehalffirst.
