SAFETY RULES

WARNING:

spark plug wire andplace wire where it can­not contact spark plug to preventaccidental
starting when setting up, transporting, ad­justing or making repairs except carburetor
adjustments.
Becauseachain saw is a high-speedwood­cutting tool, special safety precautions must
beobserved to reduce the risk of accidents.
Careless or improper use of this tool can
cause serious injury.

PLAN AHEAD

Read this manual carefully until you com-

S

pletely understand and can follow all safety
rules, precautions, and operating instruc­tions before attempting to use the unit.
Restrict theuse ofyour saw to adultusers

who understand and can follow safety
rules, precautions, and operating instruc­tions found in this manual.
Wear protective gear. Always use steel-

S

toed safety footwear with non-slip soles;
snug-fitting clothing; heavy-duty, non-slip
gloves; eye protection such as non-fog­ging, vented goggles or face screen; an
approvedsafety hardhat; andsoundbarri­ers (ear plugs or mufflers) to protect your
hearing. Regular users should have hear­ing checked regularly as chain saw noise
can damage hearing. Secure hair above

S

Serious injury to the operator,helpers, by­standers or any combination of these per­sons may result from one-handed opera­tion. A chain saw is intended for
two-handed use.
Operatethe chain saw onlyin a well-venti-

S

lated outdoor area.
Do not operate saw from a ladder or in a

tree.
Makesurethechain will not make contact

S

with any object while starting the engine.
Never try to start the saw when the guide
bar is in a cut.
Do not put pressure on the saw at the end

S

of the cut. Applying pressure can cause
you to lose control when the cut is com­pleted.
Stop the engine before setting the saw

S

down.
Do not operate a chain saw that is dam-

S

aged, improperly adjusted, or not com­pletely and securely assembled. Always
replace bar, chain, hand guard, or chain
brakeimmediately if it becomes damaged,
broken or is otherwise removed.
With the engine stopped, hand carry the

S

chain saw with the muffler away from your
body, and the guide bar and chain to the
rear,preferably covered with a scabbard.

MAINTAIN YOUR SAW IN GOOD
WORKINGORDER

Haveall chain saw service performedbya

S

qualified service dealer with the exception
of theitems listed in the maintenancesec­tionofthis manual. For example, ifimprop­ertools are used to removeor hold the fly­wheelwhen servicing the clutch, structural
damage to the flywheel can occur and
cause the flywheel to burst.
Make certain the saw chain stops moving

S

when the throttle trigger is released. For
correction, refer to CARBURETOR AD­JUSTMENTS.
Never modify your saw in any way.

and replacement parts as recommended.

HANDLE FUEL WITH CAUTION

Do not smoke while handling fuel or while

KICKBACK

WARNING:

can result in serious injury. Kickbackis the
backward,upwardorsuddenforwardmotion
of the guide bar occurring when the saw
chainnearthe uppertip of theguidebar con­tacts any object such as a log or branch, or
when the wood closes in and pinches the
sawchaininthecut. Contactingaforeignob­ject in the wood can also result in loss of
chain saw control.

RotationalKickbackcan occur when the

S

moving chain contacts an object at theup­per tip of the guide bar. This contact can
cause the chain to dig into the object,
which stops the chain for an instant. The
result is a lightning fast, reverse reaction
which kicks the guide bar up and back to­ward the operator.
Pinch-Kickback can occur when the the

S

wood closes in and pinches the moving
saw chain in the cut along the top of the
guide bar and the saw chain is suddenly
stopped. This sudden stopping of the
chain results in a reversal of the chain
force used to cut wood and causes the
sawtomovein theoppositedirectionof the
chain rotation. The saw is driven straight
back toward the operator.
Pull-In can occur when the moving chain

S

contacts a foreign object in the wood in the
cut along the bottom of the guide bar andthe
sawchainis suddenly stoppe d. Thissudden
stopping pulls the saw forward and away
from the operator and couldeasily cause the
operator to lose control of the saw.

Avoid Pinch--Kickback:

Be extremely aware of situations or ob-

S

structions that can cause material topinch
the top of or otherwise stop the chain.
Do not cut more than one log at a time.

S

Do not twist the saw as the bar is with-

S

drawn from an undercut when bucking.

AvoidPull--In:

Always begin cuttingwith theengineatfull

S

speedandthesawhousing against wood.
Use wedges made of plastic or wood.

S

Never use metal to hold the cut open.

Clear The Working Area

REDUCETHE CHANCE OF
KICKBACK

Recognize that kickback can happen.

S

With a basic understanding of kickback,
you can reduce the element of surprise
which contributes to accidents.
Neverletthemoving chain contact anyob-

S

ject at the tip of the guide bar.
Keep the working area free from obstruc-

S

tionssuchasothertrees,branches,rocks,
fences, stumps, etc. Eliminate or avoid
any obstructionthat your saw chain could
hit while you are cutting. When cutting a
branch, do not let the guide bar contact
branch or other objects around it.
Keep your saw chain sharp and properly

S

tensioned. A loose or dull chain can in­crease the chance of kickback occurring.
Follow manufacturer’s chain sharpening
andmaintenanceinstructions. Checkten­sion at regular intervals with the engine
stopped, never with the engine running.
Make sure the chain brake nuts are se­curely tightenedafter tensioning thechain.
Begin andcontinue cutting at full speed. If

S

the chain is moving at a slower speed,
thereis greater chance of kickback occur­ring.
Cut one log at a time.

S

Use extreme caution when re-entering a

S

previous cut.
Do not attempt cuts starting with the tip of

S

the bar (plunge cuts).
Watch for shifting logs or other forces that

S

could close a cut and pinch or fall into
chain.
Use the Reduced--Kickback Guide Bar

S

and Low--Kickback Chain specified for
your saw.

KICKBACKSAFETY FEATURES

WARNING:

are included on your saw to help reducethe
hazard of kickback; however, such features
will not totally eliminate this danger. As a
chainsawuser,donotrelyonlyonsafety de­vices. You must follow all safety precau­tions, instructions, and maintenance in this
manual to help avoid kickback and other
forces which can result in serious injury.

size of the kickback danger zone on the
bar tip. A Reduced--Kickback Guide Bar

push the guide bar rapidly back toward theop­erator. Either of these events may cause you
to lose contro lof the saw which could resultin
serious injury or even death. DO NOT RELY
UPON ANY OF THE DEVICES BUILT INTO
YOUR SAW. YOU SHOULD USE THE SAW
PROPERLY AND CAREFULL Y TO A VOID
KICKBACK. Reduced--kickback guide bars
and low--kickback saw chains reduce the
chance and magnitude of kickback and are
recommended. Your saw has a low kickback
chain and bar as original equipment. Repairs
on a chain brake should be made by an autho­rized servicing dealer. T ake your unit to the
place of purchase if purchased from a servic­ing dealer, or to the nearest authorized master
service dealer.

WARNING:

angle (CKA) listedonyoursaw andlisted inthe
CKA table below represents angle of kickback
your bar and chain combinations will have
when tested in accord ance with CSA (Cana­dian Standards Association) and ANSI stan­dards. When purchasing replacement bar and
chain, considerations should be given to the
lower CKA values. Lower CKA values repre­sent safer angles to the user, higher values in­dicate more angle and higher kick energies.
Computed ang les represented indicate total
energy and angle associated without activation
of the chain brake during kickback. Activated
anglerepresentschain stopping time relative to
activation angle of chain break and resulting
kick angle of saw. In all cases lower CKA val­ues represent a safer operating environment
for the user.
The following guide bar and chain combina­tions meet kickback requirements of CSA
Standards Z62.1, Z62.3, & ANSI B175.1
when used on saws listed in this manual.
Use of bar and chain combinations other
than those listed is not recommended and
may not meet the CKA requirements per
standard.

3. An adjusting pin and screw is used to ad­just the tension of the chain. It is very im­portant when assembling the bar, that the
pin located on the adjusting screw aligns
into a hole in thebar. Turningthe screw will
move the adjustment pin up and down the
screw. Locate this adjustment before you
begin mounting the bar onto the saw. See
illustration below.
