when you are fatigued, il!, or upset, or if you have taken alcohol, drugs, or
medication, You must be in good physical condition and mentally alert. If you have any condition that might
be aggravated by strenuous work, check with doctor before operating. Do not start cutting until you have a
clear work area, secure footing, and especially if you are felling a tree, a
retreat path.
........ ?
OPERATE YOUR SAW SAFELY
Do not operate with one hand. Seri- ous injury to the operator, helpers, or bystanders may result from one-
handed operation. A chain saw is in-
tended for two-handed use.
Operate the chain saw only in a well-
ventilated outdoor area.
Do not operate saw from a ladder or
in a tree, unless you are specifically
trained to do so.
Make sure the chain will not make contact 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, es- pecially at the end of the cut. Doing
so can cause you to lose control when the cut is completed.
° Stop engine before setting saw down.
Hand carry saw only when engine is stopped. Carry with muffler away from
body; guide bar & chain projecting be-
hind you; guide bar preferably cov-
ered with a scabbard.
MAINTAIN YOUR SAW IN GOOD
WORKING ORDER
- Have all chain saw service performed by a qualified service dealer except
the items listed in the maintenance
section of this manual.
Make certain the saw chain stops moving when the throttle trigger is re- leased. For correction, refer to "Car-
buretor Adjustments."
Keep the handles dry, clean, and free from oilor fuel mixture.
Keep caps and fasteners securely
tightened.
Use only Craftsman accessories and replacement parts as recommended.
Never modify your saw.
HANDLE FUEL WITH CAUTION
Do not smoke while handling fuel or while operating the saw.
Eliminateall sourcesof sparksor flame in areas where fuel is mixed or poured.
Mix and pour fuel in an outdoor area and use an approved, marked con-
tainer for aUfuel purposes. Wipe UP all fuel spills before starting saw.
Move at least 10 feet (3 meters) from fueling site before starting.
Turn the engine off and let saw cool in a non-combustible area, not on dry
leaves, straw, paper, etc. Slowly re- move fuel cap and refuel unit.
Store the unit and fuel in a cool, dry
well ventilated space where fuel va- pors cannot reach sparks or open
flames from water heaters, electdc
motors or switches, furnaces, etc.
GUARD AGAINST KICKBACK Follow all safety rules to help avoid
kickback and other forces which can result in serious injury.
_ .,,._/, Kickback Path
Avon Obstructions
Clear The WorkingArea
WARNING; Rotational Kickback can occur when the moving chain contacts
an object at the upper portion of the tip
of the guide bar, Contact at the upper portion of the tip of the guide bar 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 and Pull-In occur when
the chain is suddenly stopped by being pinched, caught, or by contacting a for-
eign object in the wood. This sudden stopping of the chain results in a rever-
sal of the chain force used to cut wood and causes the saw to move in the op- posite direction of the chain rotation.
Pinch-Kickback drives the saw straight back toward the operator. Pull-In pulls
the saw away from the operator.
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 let the moving chain contact any object at the tip of the guide bar.
Keep working area free from obstruc-
tions such as other trees, branches, rocks, fences, stumps, etc. Eliminate
or avoid any obstruction that your saw chain could hit while cutting.
Keep saw chain sharp and propedy tensioned. A loose or dull chain can
increase the chance of kickback, Fol- low manufacturer's chain sharpening
and maintenance instructions. Check tension at regular intervals, but never
with engine running. Make sure bar clamp nuts are securely tightened.
Begin and continue cutting at full speed, if the chain is moving at a slower speed, there is greater chance of kickback occurring.
Use extreme caution when reentering 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 fall into chain.
Use the specified Reduced-Kickback
Guide Bar and Low-Kickback Chain.
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 saw as bar is withdrawn
from an undercut when bucking.
Avoid Pull-In:
Always begin cutting with the engine at full speed and the saw housing
against wood.
Use wedges made of plastic or wood. Never use metal to hold the cut open.
MAINTAIN CONTROL

KICKBACK SAFETY FEATURES
WARNING: The following features are included on your saw to help reduce
hazard of kickback; however, such fea- tures will nottotally eliminate this dan- get. Do not rely only on safety devices.
Handguard: designed to reduce the
chance ofyour left hand contacting
the chain ifyour hand slips off the front handlebar.
Position offront and rear handlebars:
designed with distance between han- dles and "in-line" with each other. The
spread and "in-line" position of the hands provided by this design work together to give balance and resls-
tance in controlling the pivot of the saw back toward the operator ifkick-
back occurs.
- Reduced-Kickback Guide Bar: de- signed with a small radius tip which
reduces the size of the kickback dan- ger zone. This type bar has been
demonstrated to significantly reduce the number and seriousness of kick-
backs when tested in accordance with
ANSI B175.1.

GUIDE BAR AND CHAIN OIL
The chain oiler provides continuous lu- brication to the chain and guide bar. Be sure to fill the bar oiltank when you fill the fuel tank (Capacity = 6.8 fl. oz.).
For maximum guide bar and chain life, we recommend you use Craftsman
chain saw bar oil. If Craftsman bar oil is
not available, you may use a good
grade SAE 30 oil untilyou are able to obtain Craftsman brand. The oil output
is automatically metered during opera- tion, Your saw will use approximately
one tank of bar el! for every tank of fuel mix. Always fill the bar oil tank when
you fill the fuel tank,
.... FUEUNG ENGINE
This engine iscertified to operate on
unleaded gasoline. Before operation, gasoline must be mixed with a good quality 2-cycle air-cooled engine oil. We
recommend Craftsman brand oil. Mix gasoline and oil at a ratio of 40:i (A
40:1 ratio isobtained by mixing 3.2
ounces of oilwith 1gatlon of unleaded gasoline). DO NOT USE automotive oil or boat oil. These oils will cause engine
damage. When mixing fuel follow the instructions printed on the container.
Once oil is added to the gasoline, shake container momentarily to assure
that the fuel is thoroughly mixed. Always read and follow the safety rules
relating to fuel before fueling your unit.

OPERATING TIPS
Check chain tension before first use and after 1 minute of operation. See
Chain Tension in the Maintenance section.
Cut wood only. Do not cut metal, plas-
tics, masonry, non-wood building ma- terials, etc.
Stop the saw ifthe chain strikes a for-
eign objecL Inspect the saw and re- pair parts as necessary.
Keep the chain out of dirt and sand. Even a small amount of dirt will quick-
ly dull a chain and increase the possi- bility of kickback.
Practice cutting a few small logs using
the following steps. This will help you get the "feel" of using your saw before you begin a major sawing operation.
Squeeze the throttle trigger and al-
low the engine to reach full speed
before cutting.
Begin cuttingwith the saw frame
against the log.
Keep the engine at full speed the entire time you are cuffing.
° Allow the chain to cut for you. Exert
only light downward pressure.
Release the throttle trigger as soon
as the cut is completed, allowing the
engine to idle. If you run the saw at full throttle without a cutting load, unnecessary wear can occur.
° To avoid losing control when cut is
complete, do not put pressure on saw at end of cut.
Stop engine before setting saw down.
TREE FELLING TECHNIQUES 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 fall, nor cut at night since you will not be able to see well, nor during bad weather such as rain, snow, or strong winds, etc.
Carefully plan your sawing operation
in advance.
Clear the work area. You need a clear
area all around the tree so you can have secure footing.
Study the natural conditions that can
cause the tree to fall ina particular direction. These conditions include:
The wind direction and speed.
The lean ofthe tree. The lean of a tree might not be apparent due to
uneven or sloping terrain. Use a
plumb or level to determine the di- rection of tree lean.
° Weight and branches on one side.
Surrounding trees and obstacles.
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
2.1/2 tree lengths from the nearest person or other objects. Engine noise
can drown out a warning call. Remove dirt, stones, loose bark,
nails, staples, and wire from the tree where cuts are to be made.

FELLING LARGE TREES
(6 inches in diameter or larger)
The notch method isused 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 will tend to fall in the direction of the notch.
NOTE: If tree has large buttress roots, remove them before making the notch.
NOTCH CUT AND FELLING TREE
Make notch cut by cutting the top of the notch first. Cut through 1/3 of the
diameter of the tree. Next complete the notch by cutting the bottom. See
illustration. Once the notch is cut, re-
move the wedge ofwood from tree.

Opening of
felling cut
NOTE: Before felling cutis complete,
use wedges to open the cut when necessary to control the direction of fall.
To avold kickback and chain damage, use wood or plastic wedges, but never
steel or iron wedges.
Be alert to signs that the tree is ready to fall: cracking sounds, widening of
the felling cut, or movement in the up- per branches.
° As tree starts to fall, stop saw, put it
down, and get away quickly on your
planned retreat path.
Be extremely cautious with partially fallen trees that may be poorly sup- ported. When a tree doesn't fall com-
pletely, set the saw aside and pull
down the tree with a cable winch, block and tackle, or tractor. Do not use your saw to cut down a partially
fallen tree.
CUTTING A FALLEN TREE
(BUCKING) Bucking is the term used for cutting a
fallen tree tothe desired log size. WARNING: Do not stand on the log
being cut. Any portion can roll 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 small logs.
Never allow another person to hold the log while cutting and never hold the log with your leg or foot.
Do not cut in an area where logs, limbs, and roots are tangled. Drag logs
intoa clear area before cutting them.
BUCKING TECHNIQUES
WARNING: If saw becomes pinched

Overcutting begins on the top side of
the log with the bottom of the saw against the log. When overcutting use
light downward pressure.
Overcuttlng Undercutting
Undercutting involves cutting on the
underside of the log with top of saw against the log. When undercutting use
light upward pressure. Hold saw firmly and maintain control, The saw will tend
to push back toward you. WARNING: Never turn saw upside
