Failure to follow the warnings and instruc-
tionsmayresultinelectricshock,fireand/or
serious injury.
Save all warnings and instructions for future
reference.Theterm“powertool”inthewarnings
referstoyourmains-operated(corded)powertool
orbattery-operated(cordless)powertool.
WORK AREA SAFETY
Keep work area clean and well lit. Cluttered
ordarkareasinviteaccidents.
Do not operate power tools in explosive at-
mospheres, such as in the presence of flam-
mable liquids, gases or dust. Power tools cre-
atesparkswhichmayignitethedustorfumes.
Keep children and bystanders away while
operating a power tool. Distractionscancause
you to lose control.
ELECTRICAL SAFETY
Power tool plugs must match the outlet.
Never modify the plug in any way. Do not use
any adapter plugs with earthed (grounded)
power tools. Unmodifiedplugsandmatching
outletswillreduceriskofelectricshock.
Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. Thereisanincreasedriskofelec-
tricshockifyourbodyisearthedorgrounded.
Do not expose power tools to rain or wet
conditions. Waterenteringapowertoolwill
increasetheriskofelectricshock.
Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp
edges or moving parts. Damagedorentangled
cordsincreasetheriskofelectricshock.
When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Useofacordsuitableforoutdoorusereduces
theriskofelectricshock.
If operating a power tool in a damp location
is unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Useofa
GFCIreducestheriskofelectricshock.
PERSONAL SAFETY
Stay alert, watch what you are doing and
use common sense when operating a power
tool. Do not use a power tool while you are
tired or under the influence of drugs, alcohol
or medication.Amomentofinattentionwhile
operatingpowertoolsmayresult inserious
personalinjury.
Use personal protective equipment. Always
wear eye protection. Protective equipment
suchasdustmask,non-skidsafetyshoes,hard
hat,orhearingprotectionusedforappropriate
conditionswillreducepersonalinjuries.
Prevent unintentional starting. Ensure the
switch is in the off-position before connect-
ing to power source and/or battery pack,
picking up or carrying the tool. Carryingpower
toolswithyourfingerontheswitchorenergis-
ingpowertoolsthathavetheswitchoninvites
accidents.
Remove any adjusting key or wrench before
turning the power tool on. Awrenchorakey
leftattachedtoarotatingpartofthepowertool
mayresultinpersonalinjury.

GENERAL POWER TOOL SAFETY WARNINGS
POWER TOOL USE AND CARE
Do not force the power tool. Use the correct
power tool for your application. Thecorrect
powertoolwilldothejobbetterandsaferatthe
rateforwhichitwasdesigned.
Do not use the power tool if the switch does
not turn it on and off.Anypowertoolthatcan-
notbecontrolledwiththeswitchisdangerous
andmustberepaired.
Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventivesafetymeasuresreducetheriskof
startingthepowertoolaccidentally.
Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Powertoolsaredan-
gerousinthehandsofuntrainedusers.
Maintain power tools. Check for misalign-
ment or binding of moving parts, breakage of
parts and any other condition that may affect
the power tool’s operation. If damaged, have
the power tool repaired before use. Many ac-
cidentsarecausedbypoorlymaintainedpower
tools.
Keep cutting tools sharp and clean. Prop-
erlymaintainedcuttingtoolswithsharpcutting
edgesarelesslikelytobindandareeasierto
control.
Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Useofthe
powertoolforoperationsdifferentfromthose
intendedcouldresultinahazardoussituation.
Keep handles and grasping surfaces dry,
clean and free from oil and grease. Slippery
handlesandgraspingsurfacesdonotallowfor
safehandlingandcontrolofthetoolinunex-
pectedsituations.
BATTERY TOOL USE AND CARE
Recharge only with the charger specified by
the manufacturer. Achargerthatissuitablefor
onetypeofbatterypackmaycreateariskof
firewhenusedwithanotherbatterypack.
Use power tools only with specifically desig-
nated battery packs. Useofanyotherbattery
packsmaycreateariskofinjuryandfire.
When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small
metal objects, that can make a connection
from one terminal to another. Shortingthe
batteryterminalstogethermaycauseburnsor
a fire.
Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If
contact accidentally occurs, flush with wa-
ter. If liquid contacts eyes, additionally seek
medical help.Liquidejectedfromthebattery
may cause irritation or burns.
Do not use a battery pack or tool that is
damaged or modified. Damagedormodified
batteriesmayexhibitunpredictable behavior
resultinginfire,explosionorriskofinjury.
Do not expose a battery pack or tool to fire
or excessive temperature. Exposuretofireor
temperatureabove265°Fmaycauseexplosion.
Follow all charging instructions and do not
charge the battery pack or tool outside the
temperature range specified in the instruc-
tions. Chargingimproperlyorattemperatures
outsidethespecifiedrange maydamagethe
batteryandincreasetheriskoffire.
SERVICE
Have your power tool serviced by a qualified
repair person using only identical replace-
ment parts. Thiswillensurethatthesafetyof
thepowertoolismaintained.
When servicing a power tool, use only iden-
tical replacement parts. Follow instructions
in the Maintenance section of this manual.
Useofunauthorizedpartsorfailuretofollow
Maintenanceinstructionsmaycreateariskof
shockorinjury.
Never service damaged battery packs. Ser-
viceofbatterypacksshouldonlybeperformed
bythemanufacturerorauthorizedservicepro-
viders.

sawsmaycauseentanglementofyourclothing
orbodywiththesawchain.
Always hold the chain saw with your right
hand on the rear handle and your left hand on
the front handle. Holdingthechainsawwitha
reversedhandconfigurationincreasestherisk
ofpersonalinjuryandshouldneverbedone.
Hold the power tool by insulated gripping
surfaces only, because the saw chain may
contact hidden wiring.Sawchainscontacting
a“live”wiremaymakeexposedmetalpartsof
thepowertool“live”andcouldgivetheoperator
anelectricshock.
Wear safety glasses and hearing protec-
tion. Further protective equipment for head,
hands, legs and feet is recommended.
Adequate protective clothing will reduce per-
sonalinjurybyflyingdebrisoraccidentalcontact
withthesawchain.
Do not operate a chain saw in a tree. Opera-
tionofachainsawwhileupinatreemayresult
inpersonalinjury.
Always keep proper footing and operate
the chain saw only when standing on fixed,
secure and level surface.Slipperyorunstable
surfacessuchasladdersmaycausealossof
balanceorcontrolofthechainsaw.
When cutting a limb that is under tension be
alert for spring back.Whenthetensioninthe
woodfibresisreleasedthespringloadedlimb
maystriketheoperatorand/orthrowthechain
saw out of control.
Use extreme caution when cutting brush and
saplings. Theslendermaterialmaycatchthe
sawchainandbewhippedtowardyouorpull
you off balance.
Carry the chain saw by the front handle with
the chain saw switched off and away from
your body. When transporting or storing the
chain saw always fit the guide bar cover.
Properhandlingofthechainsawwillreducethe
likelihoodofaccidentalcontactwiththemoving
sawchain.
Follow instructions for lubricating, chain ten-
sioning and changing accessories. Improperly
tensionedorlubricatedchainmayeitherbreak
orincreasethechanceforkickback.
Do not operate a chain saw, on a ladder, from
a rooftop, or any unstable support. Operation
of a chain saw in this manner could result in
serious personal injury.
Do not operate a chain saw in a tree unless
you have been specifically trained to do so.
Operation of a chain saw in a tree without
proper training could increase the risk of
serious personal injury.
Cut wood only. Do not use chain saw for
purposes not intended. For example: do not
use chain saw for cutting plastic, masonry
or non-wood building materials.Useofthe
chainsawforoperationsdifferentthanintended
couldresultinahazardoussituation.
Do not attempt to fell a tree until you have an
understanding of the risks and how to avoid
them. Seriousinjurycouldoccurtotheoperator
orbystanderswhilefellingatree.
Follow all instructions when clearing jammed
material, storing or servicing the chain saw.
Make sure the switch is off and the battery
pack is removed. Unexpectedactuationofthe
chain saw while clearing jammed material or
servicingmayresultinseriouspersonalinjury.
CAUSES AND OPERATOR PREVENTION OF

Periodicallyglanceatthetopofthetreeduring
thebackcuttoassurethetreeisgoingtofallin
thedesireddirection.
Ifthetreestartstofallinthewrongdirection,
orifthesawgetscaughtorhungupduringthe

 Felling a tree - When bucking and felling op-
erations are being performed by two or more
persons,atthesametime,thefellingoperation
shouldbeseparatedfromthebuckingoperation
byadistanceofatleasttwicetheheightofthe
treebeingfelled.Treesshouldnotbefelledina
mannerthatwouldendangeranyperson,strike
anyutilitylineorcauseanypropertydamage.If
thetreedoesmakecontactwithanyutilityline,the
utilitycompanyshouldbenotifiedimmediately.
Beforeanycutsarestarted,pickyourescape
route(orroutesincasetheintendedrouteis
blocked);cleartheimmediateareaaroundthe
treeandmakesuretherearenoobstructionsin
yourplannedpathofretreat.Clearpathsofsafe
retreatshouldextendbackanddiagonally(45°)
totherearoftheplannedlineoffall.Whenthe
treebeginstofall,youshouldretreatawayfrom
thedirectionoffallalongaretreatpathandat
least20feetawayfromthetrunkincaseitkicks
backoverthestump.See Figure 12.
Beforefellingisstarted,considertheforceand
directionofthewind,theleanandbalanceof
thetree,andthelocationoflargelimbs.These
thingsinfluencethedirectioninwhichthetree
willfall.Donottrytofellatreealongalinedif-
ferent from its natural line of fall.
The chainsawoperatorshouldkeeponthe
uphillsideoftheterrainasthetreeislikelyto
rollorslidedownhillafteritisfelled.
Removedirt,stones,loosebark,nails,staples,
andwirefromthetreewherefellingcutsareto
bemade.
Notched Undercut.Cutanotchabout1/3the

 Astreestartstofall,stopthechainsawandput
itdownimmediately.Retreatalongthecleared
path,butwatchtheactionincasesomething
fallsyourway.Bealert for overhead limbs or
branchesthatmayfallandwatchyourfooting.
WARNING:
Nevercutthroughtothenotchwhenmakinga
backcut.Thehingecontrolsthefallofthetree,
thisisthesectionofwoodbetweenthenotch
