ADJUSTING THE CHAIN TENSION
See gure 48 - 50.
WARNING
Never touch or adjust the chain while the motor is
running. The saw chain is very sharp. Always wear
protectivegloveswhenperformingmaintenanceonthe
chain.
1. Stoptheenginebeforesettingthechaintension.
2. Makesuretheguidebarnutsareloosenedtonger
tightandturnthechaintensionerclockwisetotension
thechain.
NOTE:Acoldchainiscorrectlytensionedwhenthere
isnoslackontheundersideoftheguidebar,thechain
issnug,anditcanbeturnedbyhandwithoutbinding.
3. Re-tensionthechainwhenevertheatsonthedrive
linkshangoutofthebargroove.
NOTE:Duringnormalsawoperation,thetemperature
ofthechain increases.Thedrivelinksof acorrectly
tensioned warm chain will hang approximately
1.25 mm (0.05 inch) out of the bar groove. To help
determinethe correctwarm chaintension, thetip of
thecombinationwrench(C)canbeusedasaguide.
NOTE:Newchaintendsto stretch. Checkthechain
tensionfrequentlyandtensionasrequired.
CAUTION
A chain tensionedwhile warmmay be tootight upon
cooling.Checkthe“Adjustingthechaintension”before
nextuse.
CHAIN MAINTENANCE
See gure 51 - 52.
WARNING
CheckthattheswitchisintheSTOP“O”positionbefore
youworkonthesaw.
Use only a low-kick-back chain on this saw. This
fastcutting chain provides kick-back reduction when
properlymaintained.
Forsmoothandfastcutting,maintainthechainproperly.
Thechainrequiressharpeningwhenthewoodchipsare
smallandpowdery,thechainmustbeforcedthroughthe
woodduringcutting,orthechaincutstooneside.During
maintenanceofthechain,considerthefollowing:
1. Improperlingangleofthesideplatecanincreasethe
riskofaseverekick-back.
2. Raker(depthgauge)clearance(A).
– Toolowincreasesthepotentialforkick-back.
– Notlowenoughdecreasescuttingability.
Ifthe cutter teethhithard objectssuchas nailsand
stones,orareabradedbymudorsandonthewood,
havetheHomeliteservicedealersharpenthechain.
NOTE:Inspectthedrivesprocketforwearordamage
when replacing the chain (B). If signs of wear or
damagearepresentintheareasindicated,havethe
drivesprocketreplacedbyaHomeliteservicedealer.
