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.
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.
Never place your hand near the rotating accessory.
Accessorymaykickbackoveryourhand.
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.
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.
Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent
kickbackandlossofcontrol.
SAFETY WARNINGS SPECIFIC FOR
GRINDING OPERATIONS
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.
The grinding surface of centre depressed wheels
must be mounted below the plane of the guard lip.
Animproperlymountedwheelthatprojectsthroughthe
planeoftheguardlipcannotbeadequatelyprotected.
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operatorfrombrokenwheel
fragments,accidentalcontactwithwheelandsparksthat
couldigniteclothing.
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.
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 cut-off
wheelsmaybedifferentfromgrindingwheelflanges.
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.

OPERATING THE GRINDER
See Figure 7, page 13.
Always carefully select and use grinding wheels that are
recommended for the material to be ground. Make sure
thattheminimumoperatingspeedofanyaccessorywheel
selectedis7,500/minormore.Thegrindingwheelprovided
with the grinder is suitable for grinding welds, preparing
surfacestobewelded,grindingstructuralsteel,andgrinding
stainless steel.
To operate the grinder:
Secureallworkinaviseorclamptoaworkbench.
DANGER:
Never use the grinder with the guard removed. It has
been designed for use only with the guard installed.
Attemptingtousegrinderwithguardremovedwillresult
in loose particles being thrown against the operator
resultinginseriouspersonalinjury.

OPERATION
 Holdthegrinderinfrontandawayfromyouwithboth
hands,keepingthegrindingwheelclearoftheworkpiece.
 Turnonthegrinderandletthemotorandgrindingwheel
builduptofullspeed.
 Lower the grinder gradually until the grinding wheel
contactstheworkpiece.
WARNING:
Topreventlossofcontrolandpossibleseriouspersonal
injury, always operate the grinder with both hands,
keepingonehandonthesidehandle.
 Keepthegrindertiltedatananglefrom5°to15°and
continuouslymovingatasteady,consistentpace.
NOTICE:
Ifthegrinderisheldinonespottoolong,itwillgouge
andcutgroovesintheworkpiece.Ifthe grinderisheld
attoosharpanangle,itwillalso gougetheworkpiece
because of concentration of pressureonasmallarea.
 Use just enough pressure to keep the grinder from
chattering or bouncing.
NOTE:Heavypressurewilldecreasethegrinder’sspeedand
putastrainonthemotor.Normallytheweightofthetool
aloneisadequateformostgrindingjobs.Uselightpressure
whengrindingjaggededgesorlooseboltswherethereis
thepotentialforthegrindertosnagonthemetaledge.
