ABOUT THE CHAIN BRAKE
The main componentsofthe chainbrake assembly
are the [ever-handguard and a brakeband aroundthe
clutchdrum. The brake isautomaticallyengagedwhen
kickbackoccurs. When engaged, the brake band
clamps down aroundtheclutchdrum, stoppingboth
the drum and the chain in less than 1/10 ofone
second.The chainbrake can also beengaged
manually by pushingthe lever-handguardtowardsthe
frontofthe saw untila loud clickisheard. The saw
shouldnotbe runabove idlefor morethan a few
secondswith the brake engaged; otherwisedamage to
the saw willoccur.
To properlydisengagethe chainbrake; firmlypullthe
[ever-handguard back towardsthe hand[e(Fig. 3) until
aloudclickisheard. Failuretocompletelydisengage
the brake properlywillcauseexcessive heat build-up
onthe brakeband which,in turn, can cause severe
damage to the saw body.

Beforefellinga tree, surveyit carefullyand answer
thesequestions:
1. Inwhichdirectiondoes the tree lean?
2. Isthe condition ofthe trunksound, hollowor
partiallyrotten?
3. Fromwhichdirectionisthe windblowing?
4: What is the windvelocity?CAUTION: Wind
directionand velocitymay change. Be alert!
Fellingshouldnotbe attempted in highwinds.
5. Isthe crown(top) ofthe tree more dense and
heavieron one side?
These arefactors and forces whichwillinfluencethe
lineoffall and escape routes.
Surveythe area; make sure that felledtrees cannot
strikeany objectssuch as power lines, buildings,cars
and blockroadwaysor railroadtracks. Insurethat
neitherpersons noranimalsare withinthe danger

CUI"I'ING FELLING NOTCH
Startfellingby making a carefulfellingnotch
(undercut)first (Fig. 9). This notchdeterminestheline
of fall. Positionitat a dghtangle. Cut the fellingnotch
to a depthof about '/_of the trunkdiameter. It mustbe
wide enoughand shouldnever be higherthan its
depth.

To make the fellingnotch, startwitITthe uppercut
facing the line of fail This is a directionalcut
downwardsat an angle (Fig. 10, 1). Next, make the

CAUTION: Maintaingoodfooting,body balance and
insureasafe escape path hasbeen established.
Never fell a tree withoutmakingaproperfellingnotch
(undercut).
The nextcut(Fig. 11) iscalledthe felling cut(back
cut). Make itat least 2" higherthan the lower cut ofthe
fellingnotchbycuttinghorizontallyand parallelto the
fellingnotch. Do not cutthroughto the felling notch.
Leave a "hinge"of uncutwoodapproximately 1/10 of
thetree diameter(Fig. 11).
WARNING: To avoidpersonalinjury,do notcut
throughthe hinge!A properhinge preventsthe tree
frompossibly"sittingback"or "butt kicking"the backof
the stump,twistingoffthe stump,or fa_tingprematurely
end uncontrolled.
When fellinga large tree, drivewedges intothe felling
cut. Useonlywooden or plasticwedges. Never use
steelor ironwedges whichcan cause kickbackand
damage tothe chain. Wedges preventthe tree from
settlingbackon the bar and helpcontrolthe direction
ofthe fall towardthe fellingnotch(fig. 12).

LIMBING(Removinglimbsfromfelledtrees)
WARNING:Ofall thecuttingoperations,limbingisthe
one that holdsthe mostchanceof unforeseeninjury.
The dangerof kickbackis most prevalentduring
limbingifthe bar nosecomes incontactwithanother
branchor theside ofthetree (see "Kickback
Conditionsand Prevention'),
Professionalloggershavedevelopedvarioussafe,
efficientand effectivelimbingtechniqueswhichyou
mustfollow.The followinginstructionsare a few of the
basic safework habitsfor a chainsaw operatorwhile
limbingor removingbranchesfroma tree.
1. Beforestartingto limb,be surethe branch ison a
safe sideof thelog, uphill,and on the side
oppositeof anypotentialmotion the cutbranch
mightmake (Fig. 14).
FIGURE 14
6. Craftsmansaws are designedto allowthe
powerheed toglide over thetrunkduringlimblng.
Cut the branchesin a swingingbeckand forth
movementwiththe saw remainingon thetree.
Thisis knownas the=pendulum method."
7. Pdorto cuttingthe branches,considerthe
directionin whichthe branchesmay fall.Thiswill
determinewhetheryou cutfromthe top down
(overbuck,Fig. 16) orfrom belowup (underbuck,
Fig. 17).
8. Watch out for branches undertensionwhichcan
snap back. Tensionmustbe removedbefore
thesebranches can besafelycut. Beware of
potentialkickbacksituations.
9. If largebranchesare to be used for firewood, cut
themto lengthwhilestillattachedtothe tree.This
isan easier and safermethodthan bucking
brancheson the ground(Fig. 16 & 17).
10. Ifyou tire duringlimbing, STOP! Rest, then
resumework.
11. Never changethe positionofthe feet or hands
whileinthe midstof a cut.
RGURE16
Overbucklng
2. Do notstand onalogwhile limbing.You may slip,
fallorthe logmay roll.Maintainsure footing.
3; Never usethe bar noseto cutbranches.
4. Bendthe kneesslightly.Positionthe rightleg
behindthe leftside ofthechainsaw and the left
legforwardand outwardaway fromcontactrange
ofbar.Assumea comfortable stance withthefeet
spreadapart. CAUTION: If youchange position,
thebar mustalwaysbe on the side ofthe tree
oppositeyou. Keepthe treetrunkbetween you
and thebar.

BUCKING (The cutting of • log Into sections):
1. Be alert to the stress and motionoflogs.Always
positionyourselfto preventthe rollingofa cutlog
sectionor the stressforceswithina logfrom
actingagainstyou.
2. Never stand directlybehindthechain saw when
cutting.Stand to the leftside ofthecuttingpathof
the chainsaw to reducethechances ofinjuryfrom
kickbackor a broken chainshootingbackwards
towardsyou (Fig. 18, 1).
3. Bendthe knees slightly,Assumea comfortable
stancewiththe feet spreadapart (Fig. 18, 2).
4. Keep theleft elbowstraightwhilecuffing(Fig. 18,
3).
5. Lockthe thumb underthe handlebar(Fig. 18, 4).
RGURE18
6. Set the buckingspikesfirmlyagainstthe log.
7., When cuttingfirewood,placethe logon a suitable
supportsuch as a saw buck(Fig. 19).
RGURE 19
8. Free hanging ends can be cutoffwithoutriskof
bar pinching.But ifthe wood isnotto splitor tear,
make an undercut(underbucking,Fig. 20, 1) of
about 1/3 the depthof the logdiameter, then apply
the finishingcut (overbucking,Fig. 20, 2).
FIGURE 20
WARNING: Logsand branches may be under stress
or tension.Beforecuttingcheckto see ifstress exists.
Ifstressdoes exists, starttocut on the rightsideofthe
logor branchtoprevent pinchingand possible
kickbacksituationsso that the branch does not whip
backand strikeyou.
9. Ifthechainbar is pinchedwhile bucking,shutoff
the engine immediately.
IMPORTANT! Ifthe bar and chain become pinched,
do nottrytowrench or twistthe bar free. Move the |og
intoanotherposition or liftupwith a rod or lever (Fig.

CHECK CHAIN SHARPNESS
A sharpchainmakeswoodchips.A dullchainmakes
a sawdustpowderand cutsslowly.Chain sharpening
requiresspecialtools.You can purchasesharpening
toolsat Sear or goto a professionalchainsharpener.
REFILL BAR AND CHAIN OIL
Your saw willuse approximatelyone tank ofbar oilfor
every tankof fuelmix.Alwaysfillbar oil tankwhen you
fillthefuel tank, Formaximumbar and chainlife,we
recommendyouuse Craftsmanchainsaw bar oil. If
Craftsmanbar oilis notavailable,you may usea high
qualitybar andchainoil. CAUTION: Only usebar and
chainoil;do notusemotoroil. Motoroilwilldamage
the saw.
INSPECT BAR
Keep bar rails squareand fiat.Check for insidegroove
wear as follows.Placea straightedge (Fig.23, A)
againstside ofbar and one cutter.Ifthere is clearance
(Fig. 23, B) betweenbar and straightedge,the bar
railsare good.Ifthe chainleans (Fig. 24) and there is
no clearance betweenbar and straightedge (Fig. 24,
B), the bar rails areworn. Straighteningwornbars,
