• FailuretouseICS®brandoilmayresultinprematureenginefailureand/orupto90%reductionin
enginelife.
NOTE:1bottleofICS® two-strokeengineoilisprovidedwiththissaw.
• AlwaysrunthissawwithamixtureofgasolineandICS® two-strokeengineoil.
• AlwaysuseICS® brandtwo-strokeengineoil.Ifnotavailable,usehigh-qualityoilformulated
specificallyforair-cooledtwo-strokeengines.
• Neverusetwo-strokeoilformulatedforwater-cooledtwo-cycleengines,suchasoutboard
motor oil.
• Neverusemotoroilintendedforfour-strokeengines.
• Usehighquality,unleadedgasolinewithaminumumoctaneratingof90.Loweroctanegasoline
willcausetheenginetemperaturetoincreaseresultinginpistonseizure.
• Alwaysmeasuretheamountofgasolineandoilaccurately.Smallinaccuraciescandrastically
affecttheratioofthemixture.
ENGINE BREAK-IN
• Itisveryimportanttobreak-inanewengineto“seat”allmovingparts,especiallythepistonrings.
• Tobreak-intheengine,runonefulltankof25:1fuelatidle,cyclingthethrottleevery5to10

• Usepremiumunleadedgasolinewithaminimumoctaneratingof90.Ifloweroctanegasolineis
used,enginetemperaturewillincreasewhichcanresultinapistonseizureanddamagetothe

• Alwaysprovideadequateventilationwhenhandlingfuel.
• Usecautionwhenhandlinggasoline.Avoiddirectcontactwithskinorinhalingfuelvapor.
FUEL MIXING
• Alwaysmixgasolineandoilinacleancontainerintendedforusewithfuel.
• Keepfuelcontainerclosedtightlytopreventmoisturefromgettingintothefuel.
• Alwaysbeginmixingfuelbyaddinghalftheamountofgasolinetobeused.Thenaddthe
correctamountoftwo-strokeoilfor25:1mixtureandfinishfillingthecontainerwithgasoline.
• Donotmixmorethanonemonth’ssupplyoffuel.Thishelpspreventtheseparationofthe
two-strokeoilfromthegasoline(varnishing).
• Ifthesawisnotusedforanextendedperiodoftime(3months)thefueltankshouldbeemptied
and cleaned.

FUELING
• Alwaysshutoffthesawbeforefueling.
• Beforefueling,cleantheareaaroundfuelcaptoprevent
dirtfromcontaminatingthefuel.Contaminationofthe
fueltankcanleadtosawmalfunction.
• Thoroughlymixthefuelinit’scontainerbeforefueling.
• Slowlyopenthefuelcaptoreleaseanypressurethat
mayhavebuilt-upinthetank.
• Afteraddingfuel,tightenthefuelcapcarefullyand
securewithawrench.

PRE-CUT CHECKLIST
• Ensureproperbelttension.
• Ensurethebladeismountedcorrectly.
• Ensureallsafetydevicesareproperlymountedandfunctionalandthatallcontrolsareinproper
workingorder.
• Besuretherearenoobstructions(plumbing,electricalconduit,airducts).
• Alwayswearprotectiveclothing,includinghardhat,eyeprotection,hearingprotection,non-slip
safetyboots,gloves,andavoidwearingloosefittingclothing.
PLANNING THE CUT
• Outlinethecutwithapermanentmarkerforavisualcuttingguide.
• Avoidpinchingtheblade.Alwayscutthebottomofanopeningfirst,thentop,andthenthesides.
Savetheeasiestcutforlast.
• Forthestraightestcutsusethe“StepCut”method.Firstscoretheentirecutlineapproximatelya
half-inchdeep.Next,deepenthecutbyabouttwoinches.Thencompletethecut.
• Besurecutconcretecannotfallandinjureoperatororbystanders.Concreteisveryheavy,one

WARM ENGINE STARTING PROCEDURE
Usethesameprocedureasstartingcoldengine,butDO NOT pull choke lever out.Ifchokeis

CUTTING WITH THE RZ60C CHOP SAW
Tostartacut,holdtriggeronfullthrottleandslowlyplungethebladestraightintothewall.
CUTTING TIPS
• Alwaysoperatethesawatfullthrottle.ApplyenoughfeedforcesothatthefreerunningRPM
drops20to30%.Iftoomuchforceisapplied,thesawwilllugorstall.Thebladewillnothave
enoughspeedtocuteffectively.Iftoolittlefeedforceisapplied,thediamondswillskidandglaze
over.
• Forstraightercutsusethe“stepcut”method.Firstscoretheentirecutlinewiththeblade
approximately1/2inch(12mm)to1inch(25mm)deep.Next,deepenthecutbyabout2inches
(50mm).Thisgroovewillhelpguidethebladeforastraightcut.Thencompletethecut.
• Plungecutinsteadofstartingatthetopofthewall.Thiswillreducechatter,extendbladelife,
createastraightercut.
• Whencuttingheavyrebar,movethebladeinandoutofthesteelsothatthebladeisalways
cuttingconcreteaswellassteel.Thiswillhelpkeepthediamondsexposed.Also,expectless
diamondbladelifewhencuttingheavyrebar.
