SAFETY RULES  
S Carefully plan your sawing operation in ad-  
vance. Do not start cutting until you have a  
clear work area, secure footing, and, if you  
are felling trees, a planned retreat path.  
WARNING:  
Always disconnect  
spark plug wire and place wire where it can-  
not contact spark plug to prevent accidental  
starting when setting up, transporting, ad-  
justing or making repairs except carburetor  
adjustments.  
OPERATE YOUR SAW SAFELY  
S Do not operate a chain saw with one hand.  
Serious injury to the operator, helpers, by-  
standers or any combination of these per-  
sons may result from one-handed opera-  
Because a chain saw is a high-speed wood-  
cutting tool, special safety precautions must  
be observed to reduce the risk of accidents.  
Careless or improper use of this tool can  
cause serious injury.  
tion.  
A
chain saw is intended for  
two-handed use.  
S Operate the chain saw only in a well-venti-  
lated 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 at the end  
of the cut. Applying pressure can cause  
you to lose control when the cut is com-  
pleted.  
S Stop the engine before setting the saw  
down.  
S Do not operate a chain saw that is dam-  
aged, improperly adjusted, or not com-  
pletely and securely assembled. Always  
replace bar, chain, hand guard, or chain  
brake immediately if it becomes damaged,  
broken or is otherwise removed.  
S With the engine stopped, hand carry the  
chain saw with the muffler away from your  
body, and the guide bar and chain to the  
rear, preferably covered with a scabbard.  
PLAN AHEAD  
S Read this manual carefully until you com-  
pletely understand and can follow all safety  
rules, precautions, and operating instruc-  
tions before attempting to use the unit.  
S Restrict the use of your saw to adult users  
who understand and can follow safety  
rules, precautions, and operating instruc-  
tions found in this manual.  
S Wear protective gear. Always use steel-toed  
safety footwear with non-slip soles; snug-fit-  
ting clothing; heavy-duty, non-slip gloves;  
eye protection 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 regular-  
ly as chain saw noise can damage hearing.  
Secure hair above shoulder length.

S Have all chain saw service performed by a  
qualified service dealer with the exception  
of the items listed in the maintenance sec-  
tion of this manual. For example, if improp-  
er tools are used to remove or hold the fly-  
wheel when servicing the clutch, structural  
damage to the flywheel can occur and  
cause the flywheel to burst.

S Make certain the saw chain stops moving  
when the throttle trigger is released. For  
correction, refer to CARBURETOR AD-  
JUSTMENTS.  
S Never modify your saw in any way.  
S Keep the handles dry, clean, and free of oil  
or fuel mixture.  
S Keep fuel and oil caps, screws, and fas-  
teners securely tightened.  
S Use only HusqvarnaR accessories and  
replacement parts as recommended.  
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  
the areas where fuel is mixed or poured.  
There should be no smoking, open flames,  
or work that could cause sparks. Allow en-  
gine to cool before refueling.  
S Keep all parts of your body away from the  
chain when the engine is running.  
S Keep children, bystanders, and animals a  
minimum of 30 feet (10 meters) away from  
the work area. Do not allow other people  
or animals to be near the chain saw when  
starting or operating the chain saw.  
S Do not handle or operate a chain saw  
when you are fatigued, ill, or upset, or if you  
have taken alcohol, drugs, or medication.  
You must be in good physical condition  
and mentally alert. Chain saw work is  
strenuous. If you have any condition that  
might be aggravated by strenuous work,  
check with your doctor before operating a  
chain saw.

S Mix and pour fuel in an outdoor area on  
bare ground; store fuel in a cool, dry, well  
ventilated place; and use an approved,  
marked container for all fuel purposes.  
Wipe up all fuel spills before starting saw.  
S Move at least 10 feet (3 meters) from fuel-  
ing site before starting engine.  
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.  
Kickback Path  
Avoid Obstructions  
S Store the unit and fuel in an area where fuel  
vapors cannot reach sparks or open  
flames from water heaters, electric motors  
or switches, furnaces, etc.  
KICKBACK  
Clear The Working Area  
WARNING: Avoid kickback which  
can result 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 con-  
tacts 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 ob-  
ject 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 up-  
per 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 to-  
ward 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 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.  
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  
stopping pulls 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  
S Recognize that kickback can happen.  
With a basic understanding of kickback,  
you can reduce the element of surprise  
which contributes to accidents.  
S Never let the moving chain contact any ob-  
ject at the tip of the guide bar.  
S Keep the 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 you are cutting. When cutting a  
branch, do not let the guide bar contact  
branch or other objects around it.  
S Keep your saw chain sharp and properly  
tensioned. A loose or dull chain can in-  
crease the chance of kickback occurring.  
Follow manufacturers chain sharpening  
and maintenance instructions. Check ten-  
sion at regular intervals with the engine  
stopped, never with the engine running.  
Make sure the chain brake nuts are se-  
curely tightened after tensioning the chain.  
S Begin and continue cutting at full speed. If  
the chain is moving at a slower speed,  
there is greater chance of kickback occur-  
ring.  
S Cut one log at a time.  
S Use extreme caution when re-entering a  
previous cut.  
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.  
Avoid Pinch--Kickback:  
S Be extremely aware of situations or ob-  
structions 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 the saw as the bar is with-  
drawn from an undercut when bucking.  
S Use the Reduced--Kickback Guide Bar  
and Low--Kickback Chain specified for  
your saw.

Avoid Pull--In:  
S Always begin cutting with the engine at full

S Keep a good, firm grip on the saw with both  
hands when the engine is running and  
don’t let go. A firm grip will help you reduce  
kickback and maintain control of the saw.  
Keep the fingers of your left hand encir-  
cling and your left thumb under the front  
handlebar. Keep your right hand com-  
pletely around the rear handle whether  
your are right handed or left handed. Keep  
your left arm straight with the elbow  
locked.  
S Position your left hand on the front handle-  
bar so it is in a straight line with your right  
hand on the rear handle when making  
bucking cuts. Never reverse right and left  
hand positions for any type of cutting.  
S Stand with your weight evenly balanced on  
both feet.  
S Stand slightly to the left side of the saw to  
keep your body from being in a direct line  
with the cutting chain.  
S Do not overreach. You could be drawn or  
thrown off balance and lose control of the  
saw.  
S Do not cut above shoulder height. It is diffi-  
cult to maintain control of saw above  
shoulder height.

S Front Hand Guard, designed to reduce the  
chance of your left hand contacting the chain  
if your hand slips off the front handlebar.  
S Position of front and rear handlebars, de-  
signed with distance between handles 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 resistance in controlling the pivot of  
the saw back toward the operator if kick-  
back occurs.  
WARNING: DO NOT RELY UPON  
ANY OF THE DEVICES BUILT INTO YOUR  
SAW. YOU SHOULD USE THE SAW PROP-  
ERLY AND CAREFULLY TO AVOID KICK-  
BACK. Reduced--kickback guide bars and  
low--kickback saw chains reduce the chance  
and magnitude of kickback and are recom-  
mended. 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. Take your unit to the place of  
purchase if purchased from a servicing dealer,  
or to the nearest authorized master service  
dealer.  
S Tip contact in some cases may cause a light-  
ning fast reverse REACTION, kicking the  
guide bar up and back toward the operator.  
S Pinching the saw chain along the top of the  
guide bar may push the guide bar rapidly  
back toward the operator.  
KICKBACK SAFETY FEATURES  
WARNING: The following features  
are included on your saw to help reduce the  
hazard of kickback; however, such features  
will not totally eliminate this danger. As a  
chain saw user, do not rely only on safety de-  
vices. You must follow all safety precau-  
tions, instructions, and maintenance in this  
manual to help avoid kickback and other  
forces which can result in serious injury.  
S Reduced--Kickback Guide Bar, designed  
with a small radius tip which reduces the  
size of the kickback danger zone on the  
bar tip. A Reduced--Kickback Guide Bar  
has been demonstrated to significantly re-  
duce the number and seriousness of kick-  
backs.  
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 the safety devices built into your saw.  
CHAIN BRAKE  
S Chain Brake, designed to stop the chain in  
the event of kickback.  
WARNING:  
Your chain saw is  
Reduced Kickback Symmetrical Guide Bar  
equipped with a chain brake that is designed  
to stop the chain immediately if you get a  
kickback. The chain brake reduces the risk  
of accidents, but only you can prevent them.  
DO NOT ASSUME THAT THE CHAIN  
BRAKE WILL PROTECT YOU IN THE  
EVENT OF A KICKBACK.

S 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  
the bar. Turning the screw will move the ad-  
justment pin up and down the screw. Locate  
this adjustment before you begin mounting  
the bar onto the saw. See illustration below.  
SAFETY NOTICE: Exposure to vibrations  
through prolonged use of gasoline powered  
hand tools could cause blood vessel or nerve  
damage in the fingers, hands, and joints of  
people prone to circulation disorders or  
abnormal swellings. Prolonged use in cold  
weather has been linked to blood vessel  
damage in otherwise healthy people. If  
symptoms occur such as numbness, pain,  
loss of strength, change in skin color or texture,  
or loss of feeling in the fingers, hands, or joints,  
discontinue the use of this tool and seek  
medical attention. An anti-vibration system  
does not guarantee the avoidance of these  
problems. Users who operate power tools on  
a continual and regular basis must monitor  
closely their physical condition and the  
condition of this tool.

Adjustment located on Chain Brake  
S Turn the adjusting screw by hand counter-  
clockwise until the adjusting pin just touches  
the stop. This should allow the pin to be near  
the correct position. Further adjustment may  
be necessary as you mount the bar.  
S Slide guide bar behind clutch drum until  
guide bar stops against clutch drum  
sprocket.  
ASSEMBLY  
Protective gloves (not provided) should be  
worn during assembly.  
ATTACHING THE OPTIONAL  
BUMPER SPIKE  
The optional bumper spike may be used as a  
pivot when making a cut.  
S Loosen and remove the chain brake nuts  
and the chain brake from the saw.  
S Attach the bumper spike (optional) with the  
two screws as illustrated.  
Mount the bar  
S Prepare the chain by checking the proper di-  
rection. Without following the illustration it is  
easy to place the chain on the saw in the  
wrong direction. Use the illustration of the  
chain to determine the proper direction.

NOTE: When adjusting chain tension,  
make sure the chain brake nuts are finger  
tight only. Attempting to tension the chain  
when the chain brake nuts are tight can  
cause damage.  
FUELING & LUBRICATION  
Checking the tension:  
Use the screwdriver end of the chain adjust-  
ment tool (bar tool) to move the chain around  
the bar. If the chain does not rotate, it is too  
tight. If too loose, the chain will sag below the  
bar.  
WARNING: Remove fuel cap slow-  
ly when refueling.  
FUELING ENGINE  
This engine is certified to operate on  
unleaded gasoline. Before operation,  
gasoline must be mixed with a good quality  
2-cycle air-cooled engine oil.  
We  
recommend HusqvarnaR brand oil. If you do  
not use this oil, use a good quality 2-cycle  
air-cooled oil designed to be mixed at a ratio  
of 40:1. A 40:1 ratio is obtained by mixing  
0,125 liter of oil with 5 liters of unleaded  
gasoline. DO NOT USE automotive or boat  
oil. These oils will cause engine damage.  
When mixing fuel follow the instructions  
printed on the container. Always read and  
follow the safety rules listed under HANDLE  
FUEL WITH CAUTION.  
BAR AND CHAIN LUBRICATION  
The bar and chain require continuous lubri-  
cation. Lubrication is provided by the auto-  
matic oiler system when the oil tank is kept  
filled. Lack of oil will 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.  
Chain Adjustment  
Chain Brake Nuts  
Tool (Bar Tool)  
Adjusting the tension:  
Chain tension is very important. Chain  
stretches during use. This is especially true  
during the first few times you use your saw.  
Always check chain tension each time you  
use and refuel your saw.  
You can adjust the chain tension by  
loosening the chain brake nuts and turning  
the adjusting screw 1/4 of a turn while lifting  
up on the bar.  
S If chain is too tight, turn adjusting screw 1/4  
turn counterclockwise.  
Only use Bar and Chain Oil for bar and chain  
lubrication.  
S If chain is too loose, turn adjusting screw  
1/4 turn clockwise.

IMPORTANT POINTS TO REMEMBER  
When pulling the starter rope, do not use the  
full extent of the rope as this can cause the  
rope to break. Do not let starter rope snap  
back. Hold the handle and let the rope rewind  
slowly.  
The engine may be flooded if it has not started  
after 10 pulls.  
Flooded engines can be cleared of excess fuel  
by following the warm engine starting proce-  
dure listed above. Ensure the ON/STOP  
switch is in the ON position.  
Starting could require many pulls depending on  
how badly unit is flooded. If engine still fails to  
start, refer to the TROUBLESHOOTING  
TABLE.  
For cold weather starting, start the unit at  
FULL CHOKE; allow the engine to warm up  
before squeezing the throttle trigger.  
NOTE: Do not cut material with the choke/  
fast idle lever at the FULL CHOKE position.

S Move ON/STOP switch to the ONposition.  
S Pull the choke/fast idle lever out to the full  
extent.  
S Pull starter rope quickly with your right  
hand a maximum of 10 times.  
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 should be replaced by an autho-  
rized service dealer if any part is worn to less  
than 1/32” thick. Repairs on a chain brake  
should be made by an authorized service  
dealer. Take your unit to the place of pur-  
chase if purchased from a servicing dealer,  
or to the nearest authorized master service  
dealer.  
S This saw is equipped with a chain brake.  
The brake is designed to stop the chain if  
kickback occurs.  
NOTE: If the engine sounds as if it is trying  
to start before the 10th pull, stop pulling and  
immediately proceed to the next step.  
S The inertia--activated chain brake is  
activated 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  
disengaged by pulling the front hand guard  
back toward the front handle as far as  
possible.  
S Push the choke/fast idle lever in complete-  
ly (to the OFF CHOKE position).  
S Pull the starter rope quickly with your right  
hand until the engine starts.

TREE FELLING TECHNIQUES  
CAUTION: The chain brake must be  
checked several times daily. The engine  
must be running when performing this proce-  
dure. This is the only instance when the saw  
should be placed on the ground with the en-  
gine running.  
Place the saw on firm ground. Grip the rear  
handle with your right hand and the front han-  
dle with your left hand. Apply full throttle by  
fully depressing the throttle trigger. Activate  
the chain brake by turning your left wrist  
against the hand guard without releasing  
your grip around the front handle. The chain  
should stop immediately.  
WARNING: Check for broken or  
dead branches which can fall while cutting  
causing serious injury. Do not cut near build-  
ings or electrical wires if you do not know the  
direction of tree fall, nor cut at night since you  
will not be ale to see well, nor during bad  
weather such as rain, snow, or strong winds,  
etc. If the tree makes contact with any utility  
line, the utility company should be notified im-  
mediately.  
S Carefully plan your sawing operation in ad-  
vance.  
S Clear the work area. You need a clear area  
all around the tree so you can have secure  
footing.  
Inertia activating function control  
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.  
Natural conditions that can cause a tree to  
fall in a particular direction 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 de-  
termine the direction of tree lean.  
S Weight and branches on one side.  
S Surrounding trees and obstacles.  
WARNING: When performing the  
following procedure, the engine must be  
turned off.  
Grip the rear handle with your right hand and  
the front handle with your left hand. Hold the  
chain saw approximately 14” (35 cm) above  
a stump or other wooden surface. Release  
your grip on the front handle and use the  
weight of the saw to let the top of the guide  
bar fall forward and contact the stump.  
When the tip of the bar hits the stump, the  
brake should activate.  
Look for decay and ro.t If the trunk is rotted,  
it can snap and fall toward the operator.  
Check for broken or dead branches which  
can fall on you while cutting.  
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. En-  
gine noise can drown out a warning call.  
CUTTING METHODS  
IMPORTANT POINTS  
S Check chain tension before first use and af-  
ter 1 minute of operation. See CHAIN TEN-  
SION in the ASSEMBLY 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 ob-  
ject. Inspect the saw and repair or replace  
parts as necessary.  
Remove dirt, stones, loose bark, nails, sta-  
ples, and wire from the tree where cuts are to  
be made.  
S Keep the chain out of dirt and sand. Even a  
small amount of dirt will quickly dull a chain  
and thus increase the possibility of kickback.  
S Practice cutting a few small logs using the  
following techniques to get the “feel” of using  
your saw before you begin a major sawing  
operation.  
Plan a clear retreat path to the rear and diag-  
onal to the line of fall.  
Plan a clear retreat path  
S

S
S
Squeeze the throttle trigger and allow the  
engine to reach full speed before cutting.  
Begin cutting with the saw frame against  
the log.  
Direction of Fall  
45_  
Keep the engine at full speed the entire  
time you are cutting.  
Allow 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.  
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 de-  
sired direction of fall. After a felling cut is  
made on the opposite side of tree, the tree  
will tend to fall into the notch.  
S
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 with-  
out a cutting load, unnecessary wear can  
occur to the chain, bar, and engine.  
To avoid losing control when cut is com-  
plete, do not put pressure on saw at end  
of cut.  
NOTE: If the tree has large buttress roots,  
remove them before making the notch. If us-  
ing saw to remove buttress roots, keep saw  
chain from contacting ground to prevent dull-  
ing of the chain.

NOTCH CUT AND FELLING THE  
CUTTING A FALLEN TREE  
(BUCKING)  
Bucking is the term used for cutting a fallen  
tree to the desired log size.  
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 cut-  
ting the bottom of the notch. See illustra-  
tion. Once the notch is cut, remove the  
notch of wood from the 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.  
IMPORTANT POINTS  
S Cut only one log at a time.  
Final cut here. 2 inches above  
center of notch.  
First cut  
S Cut shattered wood very carefully; sharp  
pieces of wood could be flung toward opera-  
tor.  
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.  
Notch  
S Do not cut in an area where logs, limbs,  
and roots are tangled such as in a blown  
down area. Drag the logs into a clear area  
before cutting by pulling out exposed and  
cleared logs first.  
TYPES OF CUTTING USED FOR  
BUCKING  
Second cut  
S 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 higher than the center of the  
notch. This will leave enough uncut wood  
between the felling cut and the notch to form  
a hinge. This hinge will help prevent the tree  
from falling in the wrong direction.  
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. 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.  
Hinge holds tree on stump and helps  
control fall  
Opening  
of felling  
cut  
Use a wedge to remove pinched saw  
Closing of  
notch  
Turn saw OFF and use a plastic or  
wooden wedge to force cut open.  
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.  
S Be alert to signs that the tree is ready to fall:  
cracking sounds, widening 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 re-  
treat path.  
Overcutting begins on the top side of the log  
with the bottom of the saw against the log.  
When overcutting use light downward pres-  
sure.  
Overcutting  
Undercutting  
S DO NOT cut down a partially fallen tree  
with your saw. Be extremely cautious with  
partially fallen trees that may be poorly  
supported. 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.  
Undercutting involves cutting on the under-  
side of the log with top of saw against the log.  
When undercutting use light upward pres-  
sure. Hold saw firmly and maintain control.  
The saw will tend to push back toward you.  
WARNING: Never turn saw upside  
down to undercut. The saw cannot be con-  
trolled in this position.  
Always make your first cut on the compres-  
sion side of the log. The compression side of  
the log is where the pressure of the log’s  
weight is concentrated.

LIMBING AND PRUNING  
WARNING: Be alert for and guard  
against kickback. Do not allow the moving  
chain to contact any other branches or ob-  
jects at the nose of the guide bar when limb-  
ing or pruning. Allowing such contact can re-  
sult in serious injury.  
First cut on compression side of log  
BUCKING WITHOUT A SUPPORT  
S Overcut through 1/3 of the diameter of the  
log.  
WARNING: Never climb into a tree  
to limb or prune. Do not stand on ladders,  
platforms, a log, or in any position which can  
cause you to lose your balance or control of  
the saw.  
S Roll the log over and finish with a second  
overcut.  
S Watch for logs with a compression side to  
prevent the saw from pinching. See il-  
lustrations for cutting logs with a compres-  
sion side.  
IMPORTANT POINTS  
BUCKING USING A LOG OR  
S Work slowly, keeping both hands firmly  
gripped on the saw. Maintain secure foot-  
ing and balance.  
SUPPORT STAND  
S Remember your first cut is always on the  
compression side of the log. (Refer to the il-  
lustrations below for your first and second  
cut)  
S Watch out for springpoles. Use extreme  
caution when cutting small size limbs.  
Slender material may catch the saw chain  
and be whipped toward you or pull you off  
balance.  
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 Your first cut should extend 1/3 of the  
diameter of the log.  
S Finish with your second cut.  
Using a log for support  
nd  
2
Cut  
S Keep a clear work area. Frequently clear  
branches out of the way to avoid tripping  
over them.  
LIMBING  
S Always limb a tree after it is cut down. Only  
then can limbing be done safely and prop-  
erly.  
st  
1
Cut  
S Leave the larger limbs underneath the  
felled tree to support the tree as you work.  
S Start at the base of the felled tree and work  
toward the top, cutting branches and  
limbs. Remove small limbs with one cut.  
S Keep the tree between you and the chain.  
Cut from the side of the tree opposite the  
branch you are cutting.

S
Next make a 2nd cut all the way  
through the limb. Then cut a third  
overcut leaving a 1 to 2 inch collar from  
the truck of the tree.  
BAR MAINTENANCE  
If your saw cuts to one side, has to be forced  
through the cut, or been run with an improper  
amount of bar lubrication it may be neces-  
sary to service your bar. A worn bar will dam-  
age your chain and make cutting difficult.  
Replace your bar if bent or the inside rails of  
the bar are worn.

S Clean the oil holes after each 5 hours of op-  
eration.  
S Remove sawdust from bar groove periodi-  
cally with a wire or putty knife.
