3. Cut a notch about 1/3 the diameter of the trunk in
thesideofthetree(C).Makethenotchcutssothey
intersectatrightanglestothelineoffall.Thisnotch
shouldbecleanedouttoleaveastraightline.Tokeep
theweightofthewoodoffthesaw,alwaysmakethe
lowercutofthenotchbeforetheuppercut.
4. Maketheback-cut(D)levelandhorizontal,andata
minimumof2inches(5cm)abovethehorizontalcut
ofthenotch.
NOTE:Nevercutthroughtothenotch.Alwaysleave
a band of wood between the notch and back cut
(approximately2inches(5cm)or1/10thediameterof
thetree).Thisiscalleda“hinge”or“hingewood”(E).
Itcontrolsthefallofthetreeandpreventsslippingor
twistingorshooting-backofthetreeoffthestump.
Onlargediametertrees,stopthebackcutbeforeitis
deepenoughforthetreetoeitherfallorsettlebackon
thestump.Theninsertsoftwoodenorplasticwedges
(F)intothecutsotheydonottouchthechain.Drive
wedgesin,littlebylittle,tohelpjackthetreeover.
5. Astreestartstofall,stopthechainsawandputitdown
immediately.Retreatalongtheclearedpath,butwatch
theactionincasesomethingfallsyourway.
WARNING
Nevercutthroughtothenotchwhenmakingabackcut.
Thehingecontrolsthefallofthetree,thisisthesection
ofwoodbetweenthenotchandbackcut.
REMOVING BUTTRESS ROOTS
See gure 32.
Abuttressrootisalargerootextendingfromthetrunkof
thetreeabovetheground. Remove largebuttressroots
priortofelling.Makethehorizontalcut(A)intothebuttress
rst,followedbytheverticalcut(B).Removetheresulting
loosesection(C)fromtheworkarea.Followthecorrect
tree felling procedure afteryou haveremoved the large
buttressroots.Referto“Operation–ProperProcedurefor
TreeFelling”earlierinthismanual.
BUCKING
See gure 33.
Bucking isthe termused for cuttinga fallen treeto the
desiredloglength.
■ Cutonlyonelogatatime.
■ Supportsmalllogsonasawingstandoranotherlog
whilebucking.
■ Keepaclearcuttingarea.Makesurethatnoobjects
can contact the guide bar nose and chain during
cutting,thiscancausekick-back(A).
■ Duringbuckingoperations,standontheuphillsideso
thatthecut-offsectionofthelogcannotrolloveryou.
■ Sometimes it is impossible to avoid pinching (with
juststandardcuttingtechniques)ordifficulttopredict
whichwayalogwillsettlewhencut.
BUCKING WITH A WEDGE
See gure 34.
Ifthewooddiameterislargeenoughforyoutoinsertasoft
buckingwedge(B)withouttouchingthechain,youshould
usethewedgetoholdthecutopentopreventpinching.
BUCKING LOGS UNDER STRESS
See gure 35.
(D)Logsupportedatoneend.
(C)Logsupportedatbothends.
Maketherstbuckingcut(E)1/3ofthewaythroughthe
logandnishwitha2/3cut(F)ontheoppositeside.As
youcutthelog,itwilltendtobend.Thesawcanbecome
pinchedorhunginthelogifyoumaketherstcutdeeper
than1/3ofthediameterofthelog.
Givespecialattentiontologsunderstress(G)toprevent
thebarandchainfrompinching.
OVERBUCKING
See gure 19.
Beginfromthetopsideofthelogwiththebottomofthe
sawagainstthelog;exertlightpressuredownward.Note
thatthesawwilltendtopullawayfromyou(A).
UNDERBUCKING
Beginfromthe undersideof thelogwiththe topofthe
sawagainstthelog;exertlightpressureupward.During
underbucking,thesawwilltendtopushbackatyou(B).
Beprepared forthisreactionand holdthesaw rmlyto
maintaincontrol.
LIMBING AND PRUNING
See gure 36.
■ Workslowly, keeping both hands onthe sawwith a
firmgrip.Maintainsecurefootingandbalance.
■ Keep the tree between you and the chain while
limbing. Cut from the side of the tree opposite the
branchyouarecutting.
■ Donotcutfromaladder,thisisextremelydangerous.
Leavethisoperationforprofessionals.
■ Donotcutabovechestheightasasawheldhigheris
difficulttocontrolagainstkick-back.
