UNDERSTANDING YOUR CHAINSAW SAFETY
DEVICES
Low kick-back saw chain
Alow-kick-backsawchainisachainwhichhasmetthe
kickbackperformancerequirements.
The rakers (depth gauges) ahead of each cutter can
minimisetheforceofakick-backreactionbypreventing
the cutters from digging in too deeply at the kick-back
zone. Only use replacement chain that is equivalent to
theoriginalchainorhasbeencertiedasalowkick-back
chain.
Assawchainsaresharpened,theylosesomeofthelow
kickbackqualitiesandextracautionisrequired.
Spiked bumper
See gure 1.
Theintegralbumperspikemaybeusedasapivotwhen
makingacut.
Guide bars
Generally, guide bars with small radius tips have
somewhatlowerkick-backpotentials.
Chain brake
See gure 3.
Chainbrakesaredesignedtoquicklystopthechainfrom
rotating.Whenthechainbrakelever/handguardispushed
towards the bar, the chain should stop immediately. A
chainbrakedoesnotpreventkick-back.Thechainbrake
shouldbecleanedandtesteddaily.Referto“operation”
laterinthismanualforadditionalinformation.
(A)Runposition
(B)Brakeposition
WARNING
Even with daily cleaning of the mechanism, the
dependability of a chainbrake to perform under eld
conditionscannotbecertied.
WARNING
Kick-back occurs when the moving chain contacts
an object atthe upper portion of the tipof the guide
barorwhenthe woodclosesinandpinchesthesaw
chaininthecut.Contactattheupperportionofthetip
of theguide bar may causethe chain to diginto the
objectandstopthe chainforaninstant.Theresult is
alightning-fast,reversereactionwhichkickstheguide
barupandbacktowardstheoperator.Ifthesawchain
ispinchedalongthetopoftheguidebar,theguidebar
canbedrivenrapidlybacktowardstheoperator.Either
ofthesereactionsmaycauseyoutolosecontrolofthe
saw,whichcouldresultinseriousinjury.
Donotrelyexclusivelyuponthesafetydevicesbuiltinto
yoursaw. Asa chainsawuser, you shouldtake several
stepstokeepyourcuttingjobsfreefromaccidentorinjury.
KICK-BACK PRECAUTIONS
See gure 4 - 5.
Rotational kick-back (A) occurs when the moving chain
contacts an object at the kick-back danger zone (B)
of the guide bar. The result is a lightning-fast, reverse
reactionwhichkickstheguidebarupandbacktowards
theoperator.Thisreactioncancauselossofcontrolwhich
mayresultinseriousinjury.
WARNING
Skating - when the chainsaw fails to dig in during a
cut, the guide bar canbegin hopping or dangerously
skiddingalongthesurfaceofthelogorbranch,possibly
resulting in the loss of control of the chainsaw. To
preventorreducetheskating,holdthechainsawwith
twohandsandmakesurethesawchainestablishesa
grooveforcutting.
WARNING
Bouncing-nevercutsmall,exiblebranchesorbrushes
withyourchainsaw.Theirsizeandexibilitycaneasily
causethesawtobouncetowardsyouorbindupwith
enoughforcetocauseakickback.Thebesttoolforthat
kindofworkisahandsaw,pruningshears,anaxeor
otherhandtools.
