SAFETY RULES  
S Do not start cutting until you have a  
WARNING: Always disconnect  
spark plug wire when making repairs ex-  
cept for carburetor adjustments. Be-  
cause a chain saw is a high-speed  
woodcutting tool, special safety precau-  
tions must be observed to reduce risk of  
accidents. Careless or improper use of  
this tool can cause serious injury.  
clear work area, secure footing, and  
especially if you are felling a tree, a  
retreat path.  
OPERATE YOUR SAW SAFELY  
S 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.  
PLAN AHEAD  
S Restrict the use of your saw to adult  
users who understand and can fol-  
low the safety rules, precautions,  
and operating instructions found in  
this manual.  
S Wear protective gear. Always use  
steel-toed safety footwear with non-  
slip soles; snug-fitting clothing;  
heavy-duty, non-slip gloves; eye pro-  
tection such as non-fogging, vented  
goggles or face screen; an approved  
safety hard hat; and sound barriers  
(ear plugs or mufflers) to protect your  
hearing. Regular users should have  
hearing checked regularly as chain  
saw noise can damage hearing.  
S Operate the chain saw only in a well-  
ventilated outdoor area.  
S Do not operate saw from a ladder or  
in a tree.  
S 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.  
S 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.  
S Stop engine before setting saw down.  
S Hand carry saw only when engine is  
stopped. Carry with muffler away  
from body; guide bar & chain project-  
ing behind you; guide bar preferably  
covered with a scabbard.  
S Do not operate a chain saw that is  
damaged, improperly adjusted, or not  
completely and securely assembled.  
Always replace bar, chain, hand  
guard, chain brake, or other parts im-  
mediately if they become damaged,  
broken, or are otherwise removed.

MAINTAIN YOUR SAW IN GOOD  
WORKING ORDER  
S Have all chain saw service per-  
formed by a qualified service dealer  
except the items listed in the MAINTE-  
NANCE section of this manual.  
S Make certain the saw chain stops  
moving when the throttle trigger is  
released. For correction, refer to  
CARBURETOR ADJUSTMENTS.  
S Keep the handles dry, clean, and  
free from oil or fuel mixture.  
S Secure hair above shoulder length.  
Do not wear loose clothing or jewelry;  
they can get caught in moving parts.  
S Keep all parts of your body away  
from the chain when the engine is  
running.  
S Keep children, bystanders, and ani-  
mals at least 30 feet (10 meters)  
away from the work area when start-  
ing and using the saw.  
S Do not handle or operate a chain  
saw when you are fatigued, ill, or up-  
set, 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 oper-  
ating.  
S Keep caps and fasteners securely  
tightened.  
S Nonconforming replacement compo-  
nents or the removal of safety devices  
may cause damage to the unit and  
possible injury to the operator or by-  
standers. Use only Craftsman acces-  
sories and replacement parts as rec-  
ommended. Never modify your saw.  
S Maintain chain saw with care.

S Keep unit sharp and clean for better  
and safer performance.  
WARNING: Avoid kickback which  
can result in serious injury. Kickback  
is the backward, upward or sudden for-  
ward 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 result in  
loss of chain saw control.  
S 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.  
S Pinch-Kickback can occur when the  
the 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 sud-  
den 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.  
S 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 stop-  
ping pulls the saw forward and away  
from the operator and could easily  
cause the operator to lose control of  
the saw.  
S Follow instructions for lubricating and  
changing accessories.  
S Check for damaged parts. Before fur-  
ther use of the chain saw, a guard or  
other part that is damaged should be  
carefully checked to determine that it  
will operate properly and perform its  
intended function. Check for alignment  
of moving parts, binding of moving  
parts, breakage of parts, mounting and  
any other conditions that may affect its  
operation. A guard or other part that is  
damaged should be properly repaired  
or replaced by a Sears Service Centre  
unless otherwise indicated elsewhere  
in the instruction manual.  
S When not in use, chain saws should  
be stored in a dry, high or locked-up  
place out of the reach of children.  
S When storing saw, use a scabbard or  
carrying case.  
HANDLE FUEL WITH CAUTION  
S Do not smoke while handling fuel or  
while operating the saw.  
S Eliminate all sources of sparks or  
flame in areas where fuel is mixed or  
poured.  
S Mix and pour fuel in an outdoor area  
and use an approved, marked con-  
tainer for all fuel purposes. Wipe up  
all fuel spills before starting saw.  
S Move at least 10 feet (3 meters) from  
fueling site before starting.  
S Turn the engine off and let saw cool  
in a non-combustible area, not on  
dry leaves, straw, paper, etc. Slowly  
remove fuel cap and refuel unit.  
S 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, electric  
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.  
REDUCE THE CHANCE OF  
KICKBACK  
S Recognize that kickback can happen.  
With a basic understanding of kick-  
back, you can reduce the element of  
surprise which contributes to acci-  
dents.  
S Never let the moving chain contact  
any object at the tip of the guide bar.  
S 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.  
S When cutting a branch, do not let the  
guide bar contact another branch or  
other objects around it.  
ack Path

S Keep saw chain sharp and properly  
tensioned. A loose or dull chain can  
4
 
increase the chance of kickback.  
Follow manufacturer’s chain sharp-  
ening and maintenance instructions.  
Check tension at regular intervals,  
but never with engine running. Make  
sure chain brake nuts are securely  
tightened.  
S Begin and continue cutting at full  
speed. If the chain is moving at a  
slower speed, there is greater  
chance of kickback occurring.  
S Use extreme caution when reenter-  
ing a cut.  
S Position your left hand on the front  
handlebar so it is in a straight line  
with your right hand on the rear han-  
dle when making bucking cuts.  
Stand slightly to the left side of the  
saw to keep your body from being in  
a direct line with the cutting chain.  
S Stand with your weight evenly bal-  
anced on both feet.  
S Do not overreach. You could be  
drawn or thrown off balance and lose  
control.  
S Do not cut above shoulder height. It  
is difficult to maintain control of saw  
above shoulder height.  
S Do not attempt cuts starting with the  
tip of the bar (plunge cuts).  
S Watch for shifting logs or other forces  
that could close a cut and pinch or  
fall into chain.  
S Use the specified Reduced-Kickback  
Guide Bar and Low-Kickback Chain.  
Avoid Pinch-Kickback:  
S Be extremely aware of situations or  
obstructions that can cause material  
to pinch the top of or otherwise stop  
the chain.  
S Do not cut more than one log at a  
time.  
S Do not twist saw as bar is withdrawn  
from an undercut when bucking.  
Avoid Pull-In:  
S Always begin cutting with the engine  
at full speed and the saw housing  
against wood.  
S Use wedges made of plastic or  
wood. Never use metal to hold the  
cut open.  
KICKBACK SAFETY FEATURES  
WARNING: The following fea-  
tures are included on your saw to help  
reduce hazard of kickback; however,  
such features will not totally eliminate  
this danger. Do not rely only on safety  
devices. Follow all safety rules to help  
avoid kickback and other forces which  
can result in serious injury.  
S Front Hand Guard: designed to re-  
duce the chance of your left hand  
contacting the chain if your hand  
slips off the front handlebar.  
S Position of front 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 resis-  
tance in controlling the pivot of the  
saw back toward the operator if kick-  
back occurs.  
MAINTAIN CONTROL  
Stand to the left of the saw  
S 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.

S A good, firm grip on the saw with  
both hands will help you maintain  
control. Don’t let go. Grip the rear  
handle with your right hand whether  
you are right or left handed. Wrap the  
fingers of your left hand over and  
around the front handlebar, and your  
left thumb under the front handlebar.

S Tip contact in some cases may cause  
a lightning fast reverse REACTION,  
kicking guide bar up and back toward  
operator.  
S Pinching the saw chain along the top  
of the guide bar may push the guide  
bar rapidly back toward the operator.  
S Either of these reactions may cause  
you to lose control of the saw which  
could result in serious injury. Do not  
rely exclusively upon safety devices  
built into your saw.

S Chain Brake: designed to stop the  
chain in the event of kickback.  
WARNING: WE DO NOT REP-  
RESENT AND YOU SHOULD NOT ASSUME  
THAT THE CHAIN BRAKE WILL PROTECT  
YOU IN THE EVENT OF A KICKBACK. Kick-  
back is a lightning fast action whichthrows  
the bar and rotating chain back and up to-  
ward the operator. Kickback can be  
caused by allowing contact of the bar tip in  
the danger zone with any hard object.  
Kickback can also be caused by pinching  
the saw chain along the top of the guide  
bar. This action may push the guide bar  
rapidly back toward the operator. Either of  
these events may cause you to lose con-  
trol of the sawwhich could result in serious  
injury or even death. DO NOT RELY UPON  
ANY OF THE SAFETY DEVICES BUILT INTO  
YOUR SAW. YOU SHOULD USE THE SAW  
PROPERLY AND CAREFULLY TO AVOID  
WARNING: Computed kickback  
angle (CKA) listed on your saw and  
listed in the CKA table below represents  
angle of kickback your bar and chain  
combinations will have when tested in  
accordance with CSA (Canadian Stan-  
dards Association) 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, high-  
er values indicate more angle and high-  
er kick energies. Computed angle repre-  
sented indicates total energy and angle  
associated without activation of the  
chain brake during kickback. In all cases  
lower CKA values represent a safer op-  
erating environment for the user.  
KICKBACK.  
Reduced--kickback guide  
bars and low--kickback saw chains re-  
duce the chance and magnitude of kick-  
back and are recommended. Your saw  
has a low kickback chain and bar as origi-  
nal equipment. Repairs on a chain brake  
should be made by an authorized Sears  
Service Centre. Take your unitto the place  
of purchase or to your nearest Sears Ser-  
vice Centre.  
The following guide bar and chain com-  
binations meet kickback requirements  
of CSA Z62.1 and Z62.3 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.

ON/STOP SWITCH  
CHAIN BRAKE  
The ON/STOP SWITCH is used to stop  
the engine.  
The CHAIN BRAKE is a device de-  
signed to stop the chain if kickback oc-  
curs. The chain brake activates auto-  
matically in the event of kickback. The  
chain brake activates manually if the  
front hand guard is pushed forward.  
The chain brake is disengaged by pull-  
ing the front hand guard back toward  
the front handle as far as possible.  
THROTTLE TRIGGER  
The THROTTLE TRIGGER controls en-  
gine speed.  
THROTTLE LOCK--OUT  
The THROTTLE LOCK--OUT must be  
pressed before you can squeeze the  
throttle trigger. This feature prevents  
you from accidentally squeezing the  
trigger.  
CHAIN TENSION  
It is normal for a new chain to stretch  
during first 30 minutes of operation. You  
should check your chain tension fre-  
quently. See CHAIN TENSION under the  
SERVICE AND ADJUSTMENTS section.  
CHOKE/FAST IDLE LEVER  
The choke and fast idle are set by pull-  
ing the CHOKE/FAST IDLE LEVER out  
fully for cold or after refueling. The  
choke provides additional fuel to the  
engine during cold starting.  
WARNING: Muffler is very hot  
during and after use. Do not touch the  
muffler or allow combustible material  
such as dry grass or fuel to do so.  
BEFORE STARTING ENGINE  
line must be mixed with a good quality  
synthetic 2-cycle air-cooled engine oil.  
We recommend Craftsman brand syn-  
thetic oil. Mix gasoline and oil at a ratio  
of 40:1. A 40:1 ratio is obtained by mix-  
ing 3.2 ounces (95 ml) of oil with 1 gal-  
lon (4 litres) of unleaded gasoline. In-  
cluded with this saw is a 3.2 ounce (95  
ml) container of Craftsman brand oil.  
Pour the entire contents of this container  
into 1 gallon (4 litres) of gasoline to  
achieve the proper fuel mixture. DO NOT  
USE automotive oil or marine 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 momen-  
tarily to assure that the fuel is thoroughly  
mixed. Always read and follow the safe-  
ty rules relating to fuel before fueling  
your unit.  
WARNING: Be sure to read the  
fuel handling information in the safety  
rules section of this manual before you  
begin. If you do not understand the  
fuel handling information do not at-  
tempt to fuel your unit. Seek help from  
someone that does understand the in-  
formation or contact your Sears Ser-  
vice Centre.  
GUIDE BAR AND CHAIN OIL  
The chain oiler provides continuous  
lubrication to the chain and guide bar.  
Be sure to fill the bar oil tank when you  
fill the fuel tank (Capacity = 6.8 fl. oz.).  
Lack of oil will quickly ruin the bar and  
chain. Too little oil will cause overheat-  
ing 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 oil  
is not available, you may use a good  
grade SAE 30 oil until you are able to  
obtain Craftsman brand. The oil output  
is automatically metered during opera-  
tion. Your saw will use approximately  
one tank of bar oil for every tank of fuel  
mix. Always fill the bar oil tank when  
you fill the fuel tank.  
IMPORTANT  
Experience indicates that alcohol  
blended fuels (called gasohol or using  
ethanol or methanol) can attract mois-  
ture which leads to separation and  
formation of acids during storage.  
Acidic gas can damage the fuel sys-  
tem of an engine while in storage.  
To avoid engine problems, the fuel  
system should be emptied before stor-  
age 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.  
See STORAGE instructions for addition-  
al information.  
FUELING ENGINE  
WARNING: Remove fuel cap  
slowly when refueling.  
This engine is certified to operate on un-  
leaded gasoline. Before operation, gaso-

OPERATING TIPS  
S Check chain tension before first use  
and after 1 minute of operation. See  
CHAIN TENSION in the MAINTENANCE  
section.  
S Cut wood only. Do not cut metal,  
plastics, masonry, non-wood building  
materials, etc.  
S Stop the saw if the chain strikes a  
foreign object. Inspect the saw and  
repair parts as necessary.  
S Keep the chain out of dirt and sand.  
Even a small amount of dirt will  
quickly dull a chain and increase the  
possibility of kickback.  
S Practice cutting a few small logs us-  
ing the following steps. This will help  
you get the “feel” of using your saw  
before you begin a major sawing op-  
eration.  
S Squeeze the throttle trigger and al-  
low the engine to reach full speed  
before cutting.  
S Begin cutting with the saw frame  
against the log.  
S Keep the engine at full speed the  
entire time you are cutting.  
WARNING: If the brake band is  
worn too thin it may break when the chain  
brake is triggered. With a broken brake  
band, the chain brake will not stop the  
chain. The chain brake must be replaced  
if any part is worn to less than 0.020 inch  
(0.5 mm) thick. Repairs on a chain brake  
should be made by your Sears Service  
Centre. Take your unit to the place of pur-  
chase or to the nearest Sears Service  
Centre.  
S This saw is equipped with a chain  
brake. The brake is designed to stop  
the chain if kickback occurs.  
S The inertia--activated chain brake is ac-  
tivated if the front hand guard is pushed  
forward, either manually (by hand) or  
automatically (by sudden movement).  
S If the brake is already activated, it is dis-  
engaged by pulling the front hand guard  
back toward the front handle as far as  
possible.  
S When cutting with the saw, the chain  
brake must be disengaged.  
Disengaged  
d  
S Allow the chain to cut for you. Exert  
only light downward pressure.  
S 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.  
S To avoid losing control when cut is  
complete, do not put pressure on  
saw at end of cut.  
Braking function control  
CAUTION: The chain brake must be  
checked several times daily. The engine  
must be running when performing this  
procedure. This is the only instance  
when the saw should be placed on the  
ground with the engine running.  
S Stop engine before setting saw down.  
TREE FELLING TECHNIQUES  
Place the saw on firm ground. Hold the  
handles with both hands and apply full  
throttle. Activate the chain brake by turn-  
ing your left wrist against the hand guard  
without releasing your grip around the  
front handle. The chain should stop imme-  
diately.  
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.  
Inertia activating function control  
WARNING: When performing the  
following procedure, the engine must  
be turned off.  
S Carefully plan your sawing operation  
in advance.  
S Clear the work area. You need a  
clear area all around the tree so you  
can have secure footing.  
Hold the chain saw approximately 14”  
(35 cm) above a stump or other wood-  
en surface. Release your grip on the

Felling cut here  
S 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.  
S Study the natural conditions that can  
cause the tree to fall in a particular  
direction. These conditions include:  
S The wind direction and speed.  
S The lean of the 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.  
S Weight and branches on one side.  
S Surrounding trees and obstacles.  
S Look for decay and rot. If the trunk is  
rotted, it can snap and fall toward the  
operator.  
S 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.  
S Remove dirt, stones, loose bark,  
nails, staples, and wire from the tree  
where cuts are to be made.  
First cut  
Notch  
Hinge  
Second cut  
S After removing the wood, make the  
felling cut on the opposite side of the  
notch. This is done by making a cut  
about two inches higher than the  
center of the notch. This will leave  
enough uncut wood between the fell-  
ing cut and the notch to form a hinge.  
This hinge will help prevent the tree  
from falling in the wrong direction.  
Hinge holds tree on  
stump and helps  
control fall  
Opening of  
felling cut  
Closing  
of notch  
NOTE: Before felling cut is complete,  
use wedges to open the cut when  
necessary to control the direction of  
fall. To avoid kickback and chain  
damage, use wood or plastic wedges,  
but never steel or iron wedges.  
Plan a clear retreat path  
Direction of Fall  
45_  
S Be alert to signs that the tree is  
ready to fall: cracking sounds, widen-  
ing of the felling cut, or movement in  
the upper branches.  
S As tree starts to fall, stop saw, put it  
down, and get away quickly on your  
planned retreat path.  
S DO NOT use your saw to cut down a  
partially fallen tree. Be extremely  
cautious with partially fallen trees  
that may be poorly supported. When  
a tree doesn’t fall completely, set the  
saw aside and pull down the tree  
with a cable winch, block and tackle,  
or tractor.  
FELLING LARGE TREES  
(6 inches 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 will tend to fall in  
the direction of the notch.  
NOTE: If tree has large buttress roots,  
remove them before making the notch.  
If using saw to remove buttress roots,  
keep saw chain from contacting  
CUTTING A FALLEN TREE  
(BUCKING)  
Bucking is the term used for cutting a  
fallen tree to the desired log size.  
ground to prevent dulling of the chain.  
NOTCH CUT AND FELLING TREE  
S 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 of wood from tree.  
WARNING: Do not stand on the  
log being cut. Any portion can roll  
causing loss of footing and control. Do  
not stand downhill of the log being cut.

First cut on compression side of log  
IMPORTANT POINTS  
S Cut only one log at a time.  
S Cut shattered wood very carefully;  
sharp pieces of wood could be flung  
toward operator.  
S 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.  
Second

S Do not cut in an area where logs,  
limbs, and roots are tangled. Drag logs  
into a clear area before cutting them.  
BUCKING TECHNIQUES  
Frst cut ocompression side of log  
WARNING: If saw becomes  
pinched or hung in a log, don’t try to  
force it out. You can lose control of the  
saw resulting 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. Re-  
start saw and carefully reenter the cut.  
Do not use a metal wedge. Do not at-  
tempt to restart your saw when it is  
pinched or hung in a log.  
BUCKING WITHOUT A SUPPORT  
S Overcut through 1/3 of the diameter  
of the log.  
S Roll the log over and finish with a  
second overcut.  
S Watch for logs with a compresion  
side. See illustration for cutting logs  
with a compression side.  
BUCKING USING A LOG OR  
SUPPORT STAND  
S Remember your first cut is always on  
the compression side of the log. (Re-  
fer to the illustration below for your  
first and second cut).  
Use a wedge to remove pinched saw  
S Your first cut should extend 1/3 of the  
diameter of the log.  
S Finish with your second cut.  
Turn saw OFF and use a plastic or  
wooden wedge to force cut open.  
Using a log for support  
Overcutting begins on the top side of  
the log with the bottom of the saw  
against the log. When overcutting use  
light downward pressure.

Cut  
S Remove larger, supporting branches  
with the cutting techniques described  
in BUCKING WITHOUT A SUPPORT.  
S Always use an overcut to cut small  
and freely hanging limbs. Undercut-  
ting could cause limbs to fall and  
pinch the saw.  
LIMBING AND PRUNING  
WARNING: Be alert for and  
guard against kickback. Do not allow  
the moving chain to contact any other  
branches or objects at the nose of the  
guide bar when limbing or pruning. Al-  
lowing such contact can result in seri-  
ous injury.  
PRUNING  
WARNING: Limit pruning to limbs  
shoulder height or below. Do not cut if  
branches are higher than your shoul-  
der. Get a professional to do the job.  
S Make your first cut 1/3 of the way  
through the bottom of the limb. This  
cut will make the limb sag so that it  
falls easily on the second cut.  
WARNING: Never climb into a  
tree to limb or prune. Do not stand on  
ladders, platforms, a log, or in any po-  
sition which can cause you to lose  
your balance or control of the saw.  
IMPORTANT POINTS  
S Watch out for springpoles.  
S Next make a second cut an overcut  
all the way through the limb.  
Springpoles are small size limbs  
which can whip toward you, or pull  
you off balance. Use extreme cau-  
tion when cutting small size limbs.  
S 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.  
S Frequently clear branches out of the  
way to avoid tripping over them.  
S Finish the pruning operation by using  
an overcut so that the stump of the  
limb protrudes 1 to 2 inches from the  
trunk of the tree.

GENERAL RECOMMENDATIONS  
The warranty on this unit does not cov-  
er items that have been subjected to  
operator abuse or negligence. To re-  
ceive full value from the warranty, the  
operator must maintain unit as instruct-  
ed in this manual. Various adjustments  
will need to be made periodically to  
properly maintain your unit.  
S Once a year, replace the spark plug,  
air filter element, and check guide bar  
and chain for wear. A new spark plug  
and air filter element assures proper  
air-fuel mixture and helps your engine  
run better and last longer.  
S Fuel Tank -- Do not use saw if fuel  
tank shows signs of damage or leaks.  
S Oil Tank -- Do not use saw if oil tank  
shows signs of damage or leaks.

S Front Hand Guard  
CHECK FOR DAMAGED OR  
WORN PARTS  
CHECK CHAIN TENSION  
Contact your Sears Service Centre for  
replacement of damaged or worn parts.  
NOTE: It is normal for a small amount  
of oil to appear under the saw after en-  
gine stops. Do not confuse this with a  
leaking oil tank.  
S ON/STOP Switch -- Ensure ON/STOP  
switch functions properly by moving  
the switch to the STOP position.  
Make sure engine stops; then restart  
engine and continue.  
WARNING: Wear protective  
gloves when handling chain. The  
chain is sharp and can cut you even  
when it is not moving.  
Chain tension is very important.  
Chains stretch during use. This is es-  
pecially true during the first few times  
you use your saw. Always check  
chain tension each time you use and  
refuel your saw.

1. Use the screwdriver end of the  
chain adjustment tool (bar tool) to  
move chain around guide bar to  
ensure kinks do not exist. The  
chain should rotate freely.  
WARNING: If the saw is operated  
with a loose chain, the chain could  
jump off the guide bar and result in se-  
rious injury.  
CHECK CHAIN SHARPNESS  
A sharp chain makes wood chips. A  
dull chain makes a sawdust powder  
and cuts slowly. See CHAIN SHARP-  
ENING in the SERVICE AND ADJUST-  
MENTS section.  
CHECK GUIDE BAR  
Conditions which require guide bar  
maintenance:  
S Saw cuts to one side or at an angle.  
S Saw has to be forced through the cut.  
S 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.
