SAFETY RULES  
S Carefullyplanyour sawingoperationinad-  
vance. Donotstartcutting until youhavea  
clear work area,securefooting, 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 preventaccidental  
starting when setting up, transporting, ad-  
justing or making repairs except carburetor  
adjustments.  
Because a chain saw is a high-speedwood-  
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.  
OPERATE YOUR SAW SAFELY  
S Donotoperateachain saw with onehand.  
Serious injury to the operator, helpers, by-  
standers or any combination of these per-  
sons may result from one-handed opera-  
tion.  
A
chain saw is intended for  
two-handed use.  
S Operatethe chain saw only in a well-venti-  
lated outdoor area.  
S Do not operate saw from a ladder or in a  
tree.  
PLAN AHEAD  
S Read this manual carefully until you com-  
pletely understandand can follow all safe-  
ty rules, precautions, and operating in-  
structions before attempting to use the  
unit.  
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  
brakeimmediately 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.  
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.

MAINTAIN YOUR SAW IN GOOD  
WORKING ORDER  
S Haveall chain saw service performedby a  
qualified service dealer with the exception  
of the items listed in the maintenancesec-  
tionofthis manual. Forexample, ifimprop-  
er tools are used to remove or hold the fly-  
wheelwhenservicing theclutch, 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 Keepthehandles dry, clean, andfree of oil  
or fuel mixture.  
S Keep fuel and oil caps, screws, and fas-  
teners securely tightened.  
S Use only Husqvarna accessories and re-  
placement 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.  
Thereshould benosmoking, openflames,  
or workthatcouldcause sparks. Allow en-  
gine to cool before refueling.  
S Mix and pour fuel in an outdoor area on  
bare ground; store fuel in a cool, dry, well  
S Wear protective gear. Always use steel-  
toed safety footwear with non-slip soles;  
snug-fitting clothing; heavy-duty, non-slip  
gloves; eye protection such as non-fog-  
ging, vented goggles or face screen; an  
approvedsafetyhardhat;andsoundbarri-  
ers (ear plugs or mufflers) to protect your  
hearing. Regular users should havehear-  
ing checked regularly as chain saw noise  
can damage hearing. Secure hair above  
shoulder length.  
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 (10meters) 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  
whenyouarefatigued,ill, orupset,orifyou  
have taken alcohol, drugs, or medication.  
You must be in good physical condition  
and mentally alert. Chain saw work is

KICKBACK  
Clear The Working Area  
WARNING: Avoid kickback which  
can result in serious injury. Kickback is the  
backward,upwardorsuddenforwardmotion  
of the guide bar occurring when the saw  
chain neartheuppertip of theguidebarcon-  
tacts any object such as a log or branch, or  
when the wood closes in and pinches the  
saw chain in thecut. Contactinga foreignob-  
ject in the wood can also result in loss of  
chain saw control.  
S RotationalKickback can occur when the  
moving chain contacts an object at theup-  
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  
sawtomoveintheoppositedirection ofthe  
chain rotation. The saw is driven straight  
back toward the operator.  
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 themoving chaincontact anyob-  
ject at the tip of the guide bar.  
S Keep the working area free from obstruc-  
tionssuchas othertrees, 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 manufacturer’s chain sharpening  
andmaintenanceinstructions. Check ten-  
sion at regular intervals with the engine  
stopped, never with the engine running.  
Make surethebarclampnuts aresecurely  
tightened after tensioning the chain.  
S Begin and continue cutting at full speed. If  
the chain is moving at a slower speed,  
thereis greater chance of kickback occur-  
ring.  
S Pull-In can occur when the moving chain  
contacts a foreignobject in thewood in the  
cut along the bottom of the guide bar and  
the saw chain is suddenly stopped. This  
suddenstoppingpulls thesaw forwardand  
away from the operator and could easily  
cause the operator to lose control of the  
saw.  
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.  
S Use the Reduced--Kickback Guide Bar  
and Low--Kickback Chain specified for  
your saw.  
Avoid Pinch -Kickback:  
S Be extremely aware of situations or ob-  
structions thatcan causematerial topinch  
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.  
MAINTAIN CONTROL  
Stand to the left
the saw  
Avoid Pull-In:  
Never reverse  
hand positions  
S Always begin cutting with theengine atfull  
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  
CHAIN BRAKE AND CKA ANGLE  
S Chain Brake, designedto stop the chain in  
the event of kickback.  
WARNING: The following features  
are included on your saw to help reduce the  
hazard of kickback; however, such features  
will not totally eliminate this dangerousreac-  
tion. As achain saw user, do notrely only on  
safety 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.  
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 demonstratedto significantly re-  
duce the number and seriousness of kick-  
backs when tested in accordance with  
safety requirements for gasoline powered  
chain saws as set by ANSI B175.1.  
WARNING: WE DO NOT REP-  
RESENT AND YOU SHOULD NOT AS-  
SUME THAT THE CHAIN BRAKE WILL  
PROTECT YOU IN THE EVENT OF A  
KICKBACK. Kickback is a lightning fast ac-  
tion which throws the bar and rotating chain  
back and up toward the operator. Kickback  
can be caused by allowing contact of thebar  
tip in the danger zone with any hard object.  
Kickback canalsobecausedby pinchingthe  
sawchainalongthetopoftheguidebar. This  
action may push the guide bar rapidly back  
toward the operator. Either of these events  
may cause you to lose control of the saw  
which could result in serious injury or even  
death. DO NOT RELY UPON ANY OF THE  
DEVICES BUILT INTO YOUR SAW. YOU  
SHOULD USETHESAW PROPERLY AND  
CAREFULLY TO AVOID KICKBACK. Re-  
duced--kickback guide bars and low--kick-  
back saw chains reduce the chance and  
magnitude of kickback and are recom-  
mended. Yoursaw has a low kickback chain  
and bar as original equipment. Repairs on a

ANSI standards. When purchasing replace-  
ment 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.Computedangles rep-  
resented in the non-activated column indi-  
cate total energy and angle associated with-  
out activation of the chain brake during  
kickback. Activated angle represents chain  
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 combina-  
tions 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.

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.

WARNING: If the saw is operated  
with a loose chain, the chain could jump off  
the guide bar and result in serious injury.

FUELING & LUBRICATION  
In freezing weather oil will thicken, making it  
necessary to thin bar and chain oil with a  
small amount (5 to 10%) of #1 Diesel Fuel or  
kerosene. Bar and chain oil must be free  
flowing for the oil system to pump enoughoil  
for adequate lubrication.  
Genuine Husqvarna bar and chain oil is rec-  
ommended to protect your unit against exces-  
sive wear from heat and friction. Husqvarna oil  
resists high temperature thinning.  
If Husqvarna bar oil is not available, use agood  
grade SAE 30 oil.  
FUELING ENGINE  
WARNING: Remove fuel cap slowly  
when refueling.  
This engine is certified to operate on  
unleaded gasoline. Before operation,  
gasoline must be mixed with a good quality  
synthetic 2-cycle air-cooled engine oil  
designed to be mixed at a ratio of 40:1. A  
40:1ratiois obtainedby mixing 3.2ouncesof  
oil with 1 gallon of unleaded gasoline. DO  
NOT USE automotive oil or boat oil. These  
oils will cause engine damage. Whenmixing  
fuel, follow instructions printed on container.  
Once oil is added to gasoline, shake  
containermomentarily toassurethat thefuel  
is thoroughly mixed. Always read and follow  
the safety rules relating to fuel beforefueling  
your unit.  
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  
shownby smoke coming from thechain and/  
or discoloration of the bar.  
S Never use waste oil for bar and chain lu-  
brication.  
S Always stop the engine before removing  
the oil cap.  
IMPORTANT  
Experience indicates that alcohol--blended  
fuels (called gasohol or using ethanol 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. See STORAGE section for addi-  
tional information.

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 authorized service  
dealer if any part is worn to less than 0.020!  
(0.5 mm) thick. Repairs on a chain brake  
should be made by an authorized service deal-  
er. Take your unit to the place of purchase if  
purchased from a servicing dealer, or to the  
nearest authorized Husqvarna Service Dealer.  
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  
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  
disengagedby pulling thefronthandguard  
back toward the front handle as far as  
possible.

CUTTING METHODS  
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.  
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:  
IMPORTANT POINTS  
S Check chain tension before first use and  
after 1 minute of operation. See CHAIN  
TENSION 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 foreignob-  
ject. Inspect the saw and repair parts as  
necessary.  
S Keepthechainoutofdirtandsand. Evena  
small amountof dirt will quickly dull achain  
and increase the possibility of kickback.  
S Practice cutting a few small logs using the  
following techniques to get thefeel” of us-  
ing your saw before you begin a major  
sawing operation.  
S The wind direction and speed.  
S The lean of the tree. The lean of a tree might  
not beapparent due to uneven or sloping ter-  
rain. Use a plumb or level to determine the  
direction of tree lean.  
S
Squeeze the throttle trigger and allow  
the engine to reach full speed before  
cutting.  
S Weight and branches on one side.  
S Surrounding trees and obstacles.  
Look for decay and rot. 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.  
Remove dirt, stones, loose bark, nails, staples,  
and wire from the tree where cuts are to be  
made.  
S
S
S
S
Begin cutting with the saw frame  
against the log.  
Keep the engine at full speed the en-  
tire time you are cutting.  
Allow the chain to cut for you. Exert  
only light downward pressure.  
Releasethethrottle triggeras soonas  
the cut is completed, allowing the en-  
gine to idle. If you run the saw at full  
throttle without a cutting load, unnec-  
essary wear can occur.  
S
To avoid losing control when cut is  
complete, do not put pressure on saw  
at end of cut.  
Plan a clear retreat path to the rear and diago-  
nal to the line of fall.  
Plan a clear retreat path  
S Stop the engine before setting the saw  
down after cutting.

WARNING: Check for broken or  
dead branches which can fall while cutting  
causing serious injury. Donotcut nearbuild-  
ings or electrical wires if you donot know the  
directionof treefall, norcut atnightsince you  
will not be ale to see well, nor during bad  
weathersuch as rain, snow, or strongwinds,

NOTE: If the tree has large buttress roots,  
removethem beforemaking thenotch. If us-  
ing saw to remove buttress roots, keep saw  
chain from contactinggroundtopreventdull-  
ing of the chain.  
Bucking is the term used for cutting a fallen  
tree to the desired log length.  
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.  
S Cut shattered wood very carefully; sharp  
pieces ofwoodcould beflungtowardoper-  
ator.  
S Use a sawhorse to cut small logs. Never  
allow another person to hold the log while  
cuttingandnever holdthelog with your leg  
or foot.  
S Do not cut in an area where logs, limbs,  
and roots are tangled. Drag the logs into a  
clear area beforecutting by pulling out ex-  
posed and cleared logs first.  
NOTCH CUT AND FELLING THE  
TREE  
S Make notch cut by cutting the top of the  
notch first. Cut through 1/3 of the diameter  
ofthetree.Nextcompletethenotchbycut-

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 thesaw can beremovedeasily. Restart  
thesaw andcarefully reenterthe cut. Do not  
attempttorestartyoursaw whenit is pinched  
or hung in a log.  
Hinge  
Second cut  
S After removing the cutout of 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 felling cut and the notch to  
form a hinge. This hinge will help prevent  
the tree from falling in the wrong direction.  
Use a wedge to remove pinched saw

Undercutting  
NOTE: Before felling cut is complete, use  
wedges to open the cut when necessary to  
controlthedirectionoffall. To avoidkickback  
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.  
S DO NOT cut down a partially fallen tree with  
your saw. Be extremely cautious with par-  
tially fallen trees that may be poorly sup-  
ported. 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.  
Undercuttinginvolves cuttingon theunder-  
side ofthelog with topofsaw againstthelog.  
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 thelog. Thecompression sideof  
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 suchcontact canre-  
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.  
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 illustra-  
tion for cutting logs with a compression side.  
WARNING:Neverclimb intoatreeto  
limb or prune. Do not stand on ladders, plat-  
forms, a log, or in any position which can  
cause you to lose your balance or control of  
the saw.  
IMPORTANT POINTS  
S Work slowly, keeping both hands firmly  
gripped on the saw. Maintain secure foot-  
ing and balance.  
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.  
BUCKING USING A LOG OR SUP-  
PORT STAND  
S Remember your first cut is always on the  
compression side of the log. (Refer to the il-  
lustration below for your first and second  
cuts).  
S Your first cut should extend 1/3 of the  
diameter of the log.  
S Finish with your second cut.
