WMNINGS AND SAFETY INSTRUCTIONS
(SeeAdditional Safety Instructions throughout this Manual)
GUARD AGAINST KICKBACK
Kickback is adangerous reaction that can lead to serious
injury. Donot relyonlyonthesafetydevicesprovidedwith
oursaw.As achain sawuser,you must takespecialsafety
recautions to help keep your cuttingjobs free from acci-
ent or injury.
AKICKBACK WARNING
(ickback can occur when the moving chain con-
acts an object at the upper portion of the tip of
he guide bar or when the wood closes in and
)inchesthe saw chain in the cut. Contact at the
lpper portion of the tip of the guide bar can
;ause the chain to dig into the object, which
kops the chain for an instant. The result is a
ightning fast, reverse reaction which kicks the
wide bar up and back toward the operator. If
he saw chain is pinched along the top of the
~ide bar, the guide bar can be driven rapidly
jack toward the operator. Either of these reac-
ions can cause loss of saw control which can re-
;ultin serious injury.

Recognize that kickback can happen. With a
basic understanding of kickback, you can reduce
tJ~fJement of surprise which contributes to acci-
Never let the moving chain at the tip of the
guide bar contact any object. Figure 1.
Keep the working area free from obstruc-
tions such as other trees, branches, recks, fences,
stumps, etc. Figure 2. Eliminate or avoid any ob-
struction that your saw chain could hit while you
are cutting through aparticular log or branch.
Keep your saw chain sharp and properly ten-
sioned. Aloose or dull chain can increase the
chance of kickback to occur. Followmanufacturer’s
chain sharpening and maintenance instructions.
Check tension at regular intervals with the engine
stopped,neverwith the engine running. Makesure
thebar clampnuts aresecurelytightened afterten-
sioning the chain.
Begin and continue cutting at full throttle. If
thechainismoving ataslower speed,thereisgreat-
er chance for kickback to occur.
Cut one log at atime.
Use extreme caution when recentering a
previous cut.
Do not attempt plunge cuts.
Watch for shifting logs or other forces that could
close acut and pinch or fall into chain.
Use the Reduced-Kickback Guide Bar and
Low-Kickback Chain specifiedfor your saw.

the fingers of your left hand encircling andyou le t
thumb under the front handlebar. Keepyour right
hand completely around the rear handle whether
your areright handedor lefthanded. Keepyour left
arm straight with the elbow locked.
Position your left hand on the front handle-
bar so it is in astraight line with your right
hand on the rear handle when making buck-
ing cuts. Figure 3. Never reverse right and left
hand positions for any type of cutting.
Stand with your weight evenly balanced on
both feet.
Stand slightly to the left side of the saw to
keep your body and head from being in adi-
rect line with the cutting chain. Figure 3.
Do not overreach. Youcould be drawnor thrown
off balance and lose control of the saw.
Do not cut above shoulder height. Itisdifficult
to maintain control of saw above shoulder height.

KICKBACK SAFETY FEATURES
AWARNING
The following features are included on your saw
to help reduce the hazard of kickback; however,
such features will not totally eliminate this dan-
gerous reaction. As achain saw user, do not rely
only on safety devices. Youmust follow all safety
precautions, instructions, and maintenance in
this manual to help avoid kickback and other
forces which can result in serious i~”ury.
.Reduced-Kickback Guide Bar, desimiedwitha
small radius tip which reduces the”size~f the kick-
back dangerzone onthe bar tip. Figure 5. ARedu-
ced– Kickback Guide Bar is one which has been
demonstrated to significantly reduce the number
and seriousness of kickbacks when tested in accor-
dance with the safety re uirements for gasoline
!
powered chain sawsas set yANSI B175.1 – 1991
(American National Standards Institute, Inc.,
StandardB175.1 -1991).
.LOW-Ki&baCk Chain, designed with acon-
toured depth gauge and guard link which deflect
kickback force and allow wood to gradually ride
into the cutter. Figure 5. Low-Kickback Chainis

Use only recommended fuel mixtures.
Mix and pour fuel outdoors and where there
are no sparks or flames.
Use acontainer approved for fuel.
Donot smokeor allowsmoking nearfuelorthe

Wipe up all fuel spillsbefore starting engine.
Moveatleast 10feetawayfrom thefueling site

Use up fuel left in the carburetor by starting
the engine and letting it run until it stops.
Store unit and fuel in an area where fuel va-
pors cannot reach sparks or open flames from
waterheaters, electric motors or switches,fur-
naces, etc.
2. FUEL MIXTURE
●
●
●
●
Yourunit is powered by a2-cycle engine
which requires afuel mixture of regular
unleaded gasoline and ahigh quality en-
gine oil specially made for 2-cycle, air-
cooled engines. The internal design of the
2–cycle engine requires lubrication of moving
parts. Lubrication is provided when the rec-
ommended mixture of gasolineand oil isused.
Genuine HUSQVARNA 50:1, 2-cycle, air
cooled engine oil is strongly recom-
mended for the protection of your unit.
Extensive engineering tests have proven that
HUSQVARNAoil resistsbreak-down at oper-
ating temperatures common to 2–cycle, air
cooled engines, resulting in dependable per-
formance and longer engine life.
Gasoline must be clean and not over two
months old. Gasoline will chemically break
down and form compounds that cause hard
starting and damagein 2–cycle, air cooled en-
gines.
The correct measure of gasoline to oil is
very important. Too much oilin themixture
will foul the spark plug.
ON:IToo little oil or incorrect oil will
cause the engine to overheat and seize.
3.
4.
USE THE FOLLOWING ONLY:
HUSQVARNA50:12–cycle oil is strongly recom-
mended. A50:1 fuel mixture =2.6 oz. oil to 1gal-
lon regular unleaded gasoline. If HUSQVARNA
brand 2–cycle oil isnot available,use aood qual-
f
ity 2–cycle, air-cooled engine 011mixe ataratio
of 32:1 (4 oz. oil to 1gallon unleaded gasoline).
DO NOT USE THE FOLLOWING:

AUTOMOTIVE OIL-
Doesnot haveproper additivesfor 2–cycle, air

AWARNING I
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. Drain the gas tank,
start the engine, andlet it run until the fuel lines
and carburetor are empty. Use fresh fuel after
taking theunit out of storage. Seethe “Storage”
section for additional information. Never use
engine or carburetor cleaner products in the
fuel tank or permanent damage may occur.
5. HOW TO MIX FUEL AND FILL TANK
1. Pour theproper measure of2–cycle, aircooled
engine oil into an approved, marked fuel con-
tainer. Then, fill the container with regular
unleaded gasoline.
NOTE: If fuelis alreadyin the container,addthe
proper measure of 2–cycle engine oil. Then,
close the container tightly and shake it mo-
mentarily.
NOTE: Do notmixgasolzne andoil directly in the
fuel tank.
2. Using aspout or funnel, fill the fuel tank with
fuel mix.
3. Reinstall the fuel cap securely.

E. BAR AND CHAIN OIL
The Guide Bar and Cutting Chain require
continuous lubrication to remain in operat-
ing condition. Lubrication is provided by the
automatic 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 guide bar rails.
Genuine HLJSQVARNABar and Chain Oil is
recommended to protect your unit against
excessive wear from heat and friction.
HUSQVARNA oil resists high temperature thin-
ning. If HUSQVARNA Bar and Chain Oil is not
available,use agood grade SAE 30 oil. Never use
waste oil for bar and chain lubrication.
In freezing weather oil will thicken, making
it necessary to use HUSQVARNA winter
weight bar and chain oil, or to thin bar and
chain oil with asmall amount of Diesel Fuel
#1 or kerosene. Bar and chain oil must be free
flowing for the oil system to pump enough oil for
adequatelubrication.
1. USE THE FOLLOWING:
30° or above –- 100%lubricant -- undiluted.
30°– OOF-– 95% lubricant to 5% #l DieselFuel
or kerosene.
Below O“F – – 90% lubricant to 10% #l Diesel
Fuel or kerosene.
2. HOW TO FILL THE OIL TANK
a. Stop the engine.
b. Turnthe sawon its sidewiththe oilcapup.

cient oil for the chain whenever you start and
run the saw.
The sawwill normally use about 1/2tank
of chain oil for each tank of fuel mixture.
Iflessoilisused,checkforapluggedoilholein
theguidebar.
Keep sawdust and debris cleaned from
the oil holes in the guidebar toallowanad-
equateoilflowtothebarandchain.
Keep spilled and spattered oil wiped
from the unit to avoid sawdust and de-
bris build-up. Payparticularattentionto
oilonthefanhousingandstarterassemblyto
avoidoverheatingtheengine.
It is normal for asmall amount of oil to
appear under the saw after the engine
stem. This is excessoil draining from the bar
and chain when the saw is not in use.

TYPES OF CUTTING
A. BASIC CUTTING TECHNIQUE
1. IMPORTANT POINTS
a. Cut wood only. Do not cut metal; plastics;ma-
sonry; non-wood building materials; etc.
b. Stop the saw if the chain strikes aforeign
object. Inspect the saw and repair or replace
parts as necessary
c. Keep the chain out of dirt and sand. Evena
smallamountof dirtwill quicklydull achain
andthusincreasethepossibilityofkickback.
AWARNING
Kickback can occur when the moving chain con.
tacts an ob”ect at the upper portion of the tip of
ithe guide ar or when the wood closes in and
pinches the saw chain in the cut. Contact at the
f
uperportion of the tip of theguide bar can cause
techain to dig into the object and stop the chain
for an instant. The result is alightning fast, re-
verse reaction which kicks the guide bar up and
back toward the operatoz If the saw chain is
~inched along the top of the guide bafi the guide ar can be driven rapidly back toward the opera-
ton Either of these reactions can causeloss of saw
control which can result in serious iniurv.
Figure 16

3.
UNDERSTANDING REACTIVE FORCES
Pinch-kickback and Pull-In occur when
the chain is suddenly stopped by being
pinched, caught, or by contacting aforeign
object in the wood. This sto ping ofthe chainre-
?
sultsin areversal ofthe chain orceusedto cutwood
andcausesthe sawto move inthe oppositedirection
of chain rotation. Either reaction can result in loss
of control andpossible serious injury.
●Pinch-Kickback- -
--occurs when the chain on top of the bar is sud-
denly sto peal.
3––rapidly rives the saw straight back toward the
operatoz
.Pull-In--
--occurs when the chain on the bottom of the bar
is suddenly stopped.
––pulls the saw rapidlyforward.

Keep t” eengine at full throttle the entire
time you are cutting.
Allow the chain to cut for you; exert only
light downward pressure. If you force the cut,
damageto the bar,chain, or engine can result.
Release the throttle trigger as soon as the
cut is com leted, allowing the engine to idle.
f
Ifyou runt esaw at full throttle without acut-
ting load, unnecessary wear can occur to the
chain, bar,and engine.
To avoidlosing control when cut is complete, do
not put pressure on saw at end of cut.
Stop the engine before setting the saw down
after cutting.
B. TREE FELLING TECHNIQUES
1. CAREFULLY PLAN YOUR SAWING OPERA-
TION IN ADVANCE
a.
b,
c.
d.
e.
–12-
Clear the work area. Clear the area all
around the tree so you can have secure footing.
Study the natural conditions that can cause
the tree to fall in aparticular direction.
1.) The WIND direction and speed.
2.) The LEAN of the tree. The lean of atree
might not be apparentdueto uneven or slop-
ing terrain. Use aplumb or level to deter-
mine the direction of tree lean.
3.) WEIGHTED andBRANCHES on one side.
4.) Surrounding TREES and OBSTACLES.
Look fordecay and rot. Ifthetrunk isrotted,
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 adistance of 21/2 tree
lengthsfrom the nearestperson or other objects.
Engine noise can drown out awarning call.
f. Remove dirt, stones, loose bark, nails, staples,
andwirefromthetreewherecutsaretobemade.
g. Plan to stand on the up-hill side when cut-
ting on aslope. Figure 17.

2. FELLING SMALL TREES--LESS THAN
6“ IN DIAMETER
a. If you know the direction of fall:
1.) Make asingle felling cut on the side away
from the direction of fall.
2.) Cut all the way through.
3.) Stopthesaw,putitdown,andgetaway quick-
ly on your planned retreat path.
b. If you are not sure which way the tree will fall,
use the notch method described for felling large
trees.
AWARNING
DO NOT CUT:
–near electrical wires or buildings.
–if you do not know the direction of tree fall.
–at night since you will not be able to see well.
-during bad weather -- rain, snow,strong
wind. etc.
3. FELLING LARGE TREES--6” IN DIAME-
TER OR MORE
The notch method isusedto cutlar etrees. Anotch
%
is cut on the sideof the tree in the esireddirection
of fall. After afelling cut is made on the opposite
side of the tree, the tree will tend to fall into the
notch.
NQTEk Ifthe tree haslargebuttress roots, remove
them before making the notch. Cut into the but-
tressesvertically,then horizontally. Figure 19.
a. Make the notch cut. Figure 19.
CUT 1. Cut the top of the notch first, through
1/3of the diameter of the tree.

2. IDLE SPEED ADJUSTMENT
a. Allow the engine to idle.
b. Adjust the idle speed screw until the engine
continues to run without stalling and without
the chain moving.
–Turn screw clockwise to increase engine
speed if engine stalls or dies.
–Turn screw counterclockwise toslow engine
downandlortokeepthe chainfrom turning.
c. No further adjustments are necessary if
the chain doesnot move at idle speed and
if performance is satisfactory.
AWARNING
In “3. Low Speed Mixture Adjustment,” recheck
idle speed after each adjustment. The chain
must not move at idle speed and if performance
is satisfactory. I
3. LOW SPEED MIXTURE ADJUSTMENT
4.
a. Allow engine to idle.
b. Turn the low speed mixture screw slowly
clockwise until the RPM starts to drop. Note
the position.
c. Turn thelowspeedmixture screwslowlycoun-
terclockwise until the RPM speeds up and
startsto drop again. Note the position.
d. Set the low speed mixture screw at the mid-
point between the two positions.
ACCELERATION ADJUSTMENT
Ifthe enginediesor hesitatesinsteadof accelerat-
ing, turn the low speed mixture screw 1/16 of a
turn at atime counterclockwise until you have
smooth acceleration.
HIGH SPEED MIXTURE ADJUSTMENT
5. ----TION: IAdjustments as small as 1/16 of a
turn can a-ff~ct-engine performance. It is
important to turn the screw only 1/16 of a
turn per adjustment and test the perform-
ance of the saw before making further ad-
justments.
