GUARD AGAINST KICKBACK
Follow alI safety ruIes to help avoid
kickback and other forces which can
result in serious
injury.
_
Kickback Path
_ILWARNING:
Avoid kickback
which can resuIt in serious injury.
Kickback
is the backward, upward or
sudden forward motion of the guide
bar occurring when the saw chain near
the upper tip of the guide bar contacts
any object such as a log or branch, or
when the wood closes in and pinches
the saw chain in the cut. Contacting a
foreign object in the wood can also resuit in loss of chain saw control
• Rotational
Kickback
can occur
when the moving chain contacts an
object at the upper 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 wood ctoses 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 saw to
move in the opposite direction of the
chain rotation. The saw is driven
straight back toward the operator.
• Pull-In can occur when the moving
chain contacts a foreign object in the
wood in the cut along the bottom of
the guide bar and the saw chain is
suddenly stopped. This sudden stopping puils the saw forward and away
from the operator and could easily
cause the operator to lose control of
the saw,
REDUCE THE CHANCE OF
KICKBACK
• Recognize that kickback can happen. With a basic understanding
of
kickback, you can reduce the element of surprise which contributes to
accidents.
• Never tet the moving chain contact
any object at the tip of the guide bar.
• Keep the working area free from obstructions such as other trees,
branches, rocks, fences, stumps,
etc. Eliminate or avoid any
obstruction that your saw chain couId
hit white you are cutting.
• When cutting a branch, do not let the
guide bar contact branch or other objects around it.
• Keep saw chain sharp and properly
tensioned, A loose or dull chain can
increase the chance of kickback, Follow manufacturer's chain sharpening
and maintenance instructions. Check
tension at regular intervals, but never
with the engine running. Make sure
the bar nuts are securely tightened.
• Begin and continue cutting at futl
speed. If the chain is moving at a
slower speed, there is greater
chance of kickback occurring.
• Use extreme caution when re-entering a previous cut,
• Do not attempt cuts starting with the
tip of the bar (plunge cuts),
• Watch for shifting logs or other forces
that could close a cut and pinch or
fail into chain,
• Use the Reduced-Kickback
Guide
Bar and Low-Kickback
Chain specified for your saw,
Avoid Pinch-Kickback:
• Be extremely aware of situations or
obstructions that can cause material
to pinch the top of or otherwise stop
the chain.
• Do not cut more than one log at a
time.
• Do not twist the saw as the bar is
withdrawn from an undercut when
bucking.
Avoid Putl-ln:
• Always begin cutting with the engine
at full speed and the saw housing
against wood.
• Use wedges made of ptastic or wood.
Never use metal to ho_d the cut open.

GUIDE BAR AND CHAIN OIL
The bar and chain require lubrication.
The chain oiler provides continuous
Iubrication to the chain and guide bar.
Be sure to fiIt the bar oil tank when you
fill the fueI tank (Capacity = 6.8 ft. oz.).
Lack of oil win quickly ruin the bar and
chain. Too little oil will cause overheating shown by smoke coming from the
chain and/or discoloration of the bar.
For maximum guide bar and chain life,
we recommend you use Craftsman
chain saw bar oil. If Craftsman bar oit
is not available, you may use a good
grade SAE 30 oiI until you are aMe to
obtain Craftsman brand. The oil output
is automatically metered during operation. Your saw will use approximately
one tank of bar oil for every tank of fuel
mix. Atways fill the bar oil tank when
you fill the fuet tank.
FUELING ENGINE
_WARNING:
Remove fuel cap
slowly when refueling.
This engine is certified to operate on
unteaded gasoline. Before operation,
gasotine must be mixed with a good
quatity synthetic 2-cycIe air-cooIed engine oil. We recommend Craftsman
brand synthetic oil. Mix gasoline and
oit at a ratio of 40:1. A 40:1 ratio is obtained by mixing 3.2 ounces of oil with
1 gailon of unleaded gasoline. Included
with this saw is a 3.2 ounce container of
oil Pour the entire contents of this container into 1 gallon of gasoline to
achieve the proper fuel mixture.
DO NOT USE automotive or boat oil
These oils wiit cause engine damage.
When mixing fuel fottow the instructions printed on the oil container. Once
oil is added to the gasoline, shake
container momentarily to assure that
the fuet is thoroughly mixed. Always
read and follow the safety rules relating to fueI before fueling your unit.
IMPORTANT
Experience indicates that alcoholblended fueis (called gasohol or using
ethanot or methanol) can attract moisture which leads to separation and
formation of acids during storage. Acidic
gas can damage the fuel system of an
engine while in storage. To avoid engine
problems, the fuel system should be
emptied before storage for 30 days or
longer. Drain the gas tank, start the engine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel
next season. Never use engine or carburetor cteaner products in the fuel tank
or permanent damage may occur,
See the STORAGE section for additionai
information
CHAIN BRAKE

OPERATING TIPS
• Check chain tension before first use,
after 1 minute of operation, and each
time before you start the chain saw.
See CHAIN TENSION in the MAINTENANCE section.
• Cut wood only. Do not cut metal, plastics, masonry, non-wood building materials, etc.
• Stop the saw if the chain strikes a
foreign object. Inspect the saw and
repair or replace parts as necessary,
If the chain jumps off the guide bar,
inspect the chain for damaged drive
tinks before reinstalling. Burrs on
drive links, which prevent them from
entering the groove of the guide bar,
can be removed with a flat fiIe.
• Keep the chain out of dirt and sand.
Even a small amount of dirt will dull a
chain, increase the possibility of kickback, and require chain sharpening or
replacement.
• Practice cutting a few small logs using the following techniques to get
the "feeF of using your saw before
you begin a major sawing operation.
• Squeeze the throttte trigger and alIow the engine to reach fuli speed
before cutting.
• Begin cutting with the saw frame
against the log.
• Keep the engine at fuji speed the
entire time you are cutting.
•AlIow
the chain to cut for you. Exert only light downward pressure.
If you force the cut, damage to the
bar, chain, or engine can result.
• Release the throttie trigger as
soon as the cut is completed, attowing the engine to idle. If you
run the saw at full throttle without
a cutting load, unnecessary wear
can occur to the chain, bar, and
engine. To maximize operating
efficiency, do not run the engine
for longer than 30 _econd8 at a
time at full throttle.
• To avoid losing control when cut is
complete, do not put pressure on
saw at end of cut.
• Stop the engine before setting the
saw down after cutting.

TREE FELLING
TECHNIQUES
_II, WARNING:
Check for broken or
dead branches which can fall while cutting causing serious injury. Do not cut
near buildings or electrical wires if you
do not know the direction of tree falt, nor
cut at night since you will not be aIe to
see well, nor during bad weather such
as rain, snow, or strong winds, etc.
If the tree makes contact with any utility
Iine, the utility company should be notified immediately.
•Carefuily
plan your sawing operation
in advance.
• Ctear the work area. You need a ciear
area nil around the tree so you can
have secure footing.
• The chain saw operator shoutd keep
on the uphill side of the terrain as the
tree is likely to roll or slide downhill
after it is felled.
• Study the natural conditions that can
cause the tree to fall in a particular direction.
Natural conditions that can cause a tree
to fail in a particular direction include:
• The wind direction and speed.
• The lean of the tree. The tean of a
tree might not be apparent due to uneven or sloping terrain, Use a piumb
or level to determine the direction of
tree lean.
• Weight and branches on one side.
• Surrounding trees and obstactes.
Look for decay and rot. If the trunk is
rotted, it can snap and fall toward the
operator. Make sure there is enough
room for the tree to fall. Maintain a distance of 2 1/2tree lengths from the nearest person or other objects. Engine
noise can drown out a warning call.
Remove dirt, stones, loose bark, naiis,
staples, and wire from the tree where
cuts are to be made.
Plan a ctear retreat path to the rear
and diagonal to the line of fail

FELLING LARGE TREES
(6 inches (15 cm) in diameter or larger)
The notch method is used to fell large
trees. A notch is cut on the side of the
tree in the desired direction of fall. After
a felling cut is made on the opposite
side of tree, the tree wiII tend to fail into
the notch.
NOTE: If the tree has large buttress
roots, remove them before making the
notch, tf using saw to remove buttress
roots, keep saw chain from contacting
ground to prevent dutiing of the chain.
NOTCH CUT AND FELLING THE
TREE
• Make notch cut by cutting the top of
the notch first. Cut through _,/3of the
diameter of the tree. Next compiete
the notch by cutting the bottom of the
notch. See iflustration. Once the
notch is cut remove the notch of
wood from the tree.
FinaI (felling) cut here, 2 inches
(5 cm) above center of notch.

_...L
Notch --.... __._2

Hinge
• After removing the wood from the
notch, make the felling cut on the opposite side of the notch. This is done
by making a cut about two inches (5
cm) higher than the center of the
notch. This wilt leave enough uncut
wood between tile felting cut and the
notch to form a hinge. This hinge wilt
help prevent the tree from falting in the
wrong direction.

control tall

NOTE: Before felling cut is complete,
use wedges to open the cut if necessary
to contro_ the direction of fail. To avoid
kickback and chain damage, use wood
or ptastic wedges, but never steel or iron
wedges.
• Be alert to signs that the tree is
ready to falt: cracking sounds, widening of the feI_ing cut, or movement in
the upper branches.
• As tree starts to fall, stop saw, put it
down, and get away quickly on your
ptanned retreat path.
• DO NOT cut down a partially fatIen tree
with your saw. Be extremely cautious
with partialIy falten trees that may be
poorty supported. When a tree doesn't
falt completely, set the saw aside and
pult down the tree with a cable winch,
b_ock and tackle, or tractor.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a
fallen tree to the desired _og size.
_IJWARNING:
Do not stand on the
tog being cut. Any portion can rott
causing toss of footing and control, Do
not stand downhill of the log being cut.
IMPORTANT
POINTS
• Cut only one log at a time.
• Cut shattered wood very carefully;
sharp pieces of wood could be flung
toward operator.
• Use a sawhorse to cut smatt logs.
Never aItow another person to hold
the Iog white cutting and never hold
the Iog with your _eg or foot.
• Do not cut in an area where togs,
_imbs, and roots are tang_ed such as
in a blown down area. Drag the togs
into a clear area before cutting by
pu_ting out exposed and cleared togs
first.
TYPES OF CUTTING
BUCKING
_ll WARNING:
USED FOR
If saw becomes
pinched or hung in a log, don't try to
force it out. You can _ose control of the
saw resuIting in injury and/or damage
to the saw. Stop the saw, drive a
wedge of plastic or wood into the cut
until the saw can be removed easily.
Restart the saw and carefully reenter
the cut. To avoid kickback and chain
damage, do not use a metal wedge.
Do not attempt to restart your saw
when it is pinched or hung in a log.
Use a wedge
to remove
pinched
saw
Turn saw OFF and use e plastic or
wooden wedge to force cut open.
Overcutting begins on the top side of
the log with the bottom of the saw
against the _og. When overcutting use
light downward pressure.

wilt tend to push back toward you.
_WARNING:
Never turn saw upside down to undercut.
The saw cannot be controlled in this position.
Always make your first cut on the compression side ofthe log. The compression side of the tog is where the pressure of the log's weight is
concentrated.

• Watch out for springpoles. SpringpoIes
are smalt size limbs which can catch
the saw chain and whip toward you or
pull you off balance. Use extreme caution when cutting small size limbs or
slender material.
• Be alert for springback. Watch out for
branches that are bent or under
pressure. Avoid being struck by the
branch or the saw when the tension
in the wood fibers is released.
• Keep a clear work area. Frequently
clear branches out of the way to avoid
tripping over them.
LIMBING
• Always Iimb a tree after it is cut
down. Onty then can limbing be done
safely and properly.
• Leave the larger limbs underneath the
felled tree to support the tree as you
work.
• Start at the base of the felled tree and
work toward the top, cutting branches
and limbs. Remove smaII limbs with
one cut.
• Keep the tree between you and the
chain. Cut from the side of the tree
opposite the branch you are cutting.
• Remove larger, supporting branches
with the cutting techniques described
in BUCKING WITHOUT A SUPPORT.
• Always use an overcut to cut small
and freely hanging limbs. Undercutting
could cause limbs to fall and pinch the

NOTE: The chain is tensioned correctly
when the weight of the chain does not
cause it to sag below the guide bar
(with the chain saw sitting in an upright
position), but the chain still moves freely
around the guide bar.
_I_WARNING:
If the saw is operated
with a loose chain, the chain could jump
off the guide bar and result in serious
injury to the operator and/or damage the
chain making it unusable. If the chain
jumps off the guide bar, inspect each
drive link for damage. Damaged chain
must be repaired or replaced.
CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A
dull chain makes a sawdust powder
and cuts slowly. See CHAIN SHARPENING.
CHECK GUIDE BAR
Conditions which require guide bar
maintenance:
• Saw cuts to one side or at an angle.
• Saw has to be forced through the cut,
• Inadequate supply of oil to bar/chain.
Check the condition of guide bar each
time chain is sharpened. A worn guide
bar will damage the chain and make
cutting difficult.
15
After each use, ensure ON/STOP
switch is in the STOP position, then
clean all sawdust from the guide bar
and sprocket hole.
To maintain guide bar:
• Move ON/STOP switch to STOR
• Loosen and remove bar Ruts and
clutch cover. Remove bar and chain
from saw.
• Clean the oft holes and bar groove
after each 5 hours of operation.
• Burring of guide bar rails is a normal
process of rail wear. Remove these
burrs with a flat file.
• When rail top is uneven, use a flat
file to restore square edges and
