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.  
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.  
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-  
tion.  
A
chain saw is intended for  
two-handed use.  
S Operate the chain saw only in a well-venti-  
lated outdoor area.  
PLAN AHEAD  
S Do not operate saw from a ladder or in a  
tree, unless you are specifically trained to  
do so.  
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 completed.  
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 Read this manual carefully until you com-  
pletely understand and can follow all safe-  
ty rules, precautions, and operating in-  
structions 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.

MAINTAIN YOUR SAW IN GOOD  
WORKING ORDER  
S Have all chain saw service performed by a  
qualified service dealer with the exception of  
the items listed in the maintenance section of  
this manual. For example, if improper tools  
are used to remove or hold the flywheel  
when servicing the clutch, structural damage  
to the flywheel can occur and cause the fly-  
wheel to burst.  
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  
approved safety hard hat; and sound barri-  
ers (ear plugs or mufflers) to protect your  
hearing. Regular users should have hear-  
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 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 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. Use  
only attachments supplied or specifically  
recommended by the manufacturer.  
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 JonseredR 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.  
There should be no smoking, open flames,  
or work that could cause 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 venti-  
lated 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.  
Kickback Path  
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.  
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.  
Clear the working area  
KICKBACK  
REDUCE THE CHANCE OF  
KICKBACK  
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 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 through a particular log  
or branch.  
S Keep your saw chain sharp and properly  
tensioned. A loose or dull chain can increase  
the chance of kickback occurring. Follow  
manufacturer’s chain sharpening and main-  
tenance instructions. Check tension at regu-  
lar intervals with the engine stopped, never  
with the engine running. Make sure the bar  
clamp nuts are securely tightened after ten-  
sioning 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 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.  
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 obstruc-  
tions that can cause material to pinch the top  
of or otherwise stop the chain.  
MAINTAIN CONTROL  
Stand to the le
the saw  
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.  
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.  
Never reverse  
hand positions

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 Handguard, designed to reduce the  
chance of your left hand contacting the  
chain if your hand slips off the front handle-  
bar.  
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  
PROPERLY AND CAREFULLY TO AVOID  
KICKBACK. Reduced--kickback guide bars  
and low--kickback saw chains reduce the  
chance and magnitude of kickback and are  
recommended. Your saw has a low kick-  
back 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 au-  
thorized master service dealer.  
S Tip contact in some cases may cause a  
lightning fast reverse REACTION, kicking  
the guide bar up and back toward the oper-  
ator.  
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 dangerous reac-  
tion. As a chain saw user, do not rely 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 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  
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.

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.  
Place chain onto the sprocket  
7. Place chain over and behind clutch, fitting  
the drive links in the clutch drum sprocket.  
8. Fit bottom of drive links between the  
teeth in the sprocket in the nose of the  
guide bar.  
S If chain is too tight, turn adjusting screw 1/4

S If chain is too loose, turn adjusting screw  
1/4 turn clockwise.  
9. Fit chain drive links into bar groove.  
10. Pull guide bar forward until chain is snug  
in guide bar groove. Ensure all drive  
links are in the bar groove.  
11. Now, install chain brake making sure the  
adjusting pin is positioned in the lower  
hole in the guide bar. Remember this pin  
moves the bar forward and backward as  
the screw is turned.  
12. Install chain brake nuts and finger tighten  
only. Once the chain is tensioned, you  
will need to tighten chain brake nuts.

CHAIN TENSION (Including units  
with chain already installed)  
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.  
S Lift up the tip of the bar and securely tight-  
en the chain brake nuts with the bar tool.  
S Recheck chain tension.  
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: If the saw is operated  
with a loose chain, the chain could jump off  
the guide bar and result in serious injury.  
WARNING: Muffler is very hot during  
and after use. Do not touch the muffler or al-  
low combustible material such as dry grass  
or fuel to do so.

FUELING ENGINE  
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.  
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 2-cycle air-cooled  
engine 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  
Only use Bar and Chain Oil for bar and chain  
lubrication.

6. Allow the engine to run for approximately  
5 seconds. Then, squeeze and release  
the throttle trigger to release the fast idle,  
allowing the engine to idle.  
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,  
empty the fuel system before storage for 30  
days or longer. Drain the gas tank, start the en-  
gine and let it run until the fuel lines and carbu-  
retor are empty. Use fresh fuel next season.  
Never use engine or carburetor cleaner prod-  
ucts in the fuel tank or permanent damage may  
occur.

STARTING A FLOODED ENGINE  
The engine may be flooded with too much  
fuel if it has not started after 10 pulls. Flooded  
engines can be cleared of excess fuel by fol-  
lowing the warm engine starting procedure  
listed above. Insure the ON/STOP switch is  
in the ON position. Starting could require  
pulling the starter rope handle many times  
depending on how badly the unit is flooded. If  
engine fails to start refer to the TROUBLE-  
SHOOTING TABLE.  
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.  
For cold weather starting, start the unit at full  
choke; allow the engine to warm up before  
squeezing the throttle trigger.

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  
0,02! (0,5 mm) thick. Repairs on a chain  
brake should be made by an authorized ser-  
vice dealer. Take your unit to the place of pur-  
chase if purchased from a servicing dealer,  
or to the nearest authorized master service  
dealer.

CUTTING METHODS  
Carefully plan your sawing operation in ad-  
vance. You need a clear area all around the  
tree so you can have secure footing. Check  
for broken or dead branches which can fall  
on you causing serious injury.  
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  
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 using the  
following techniques to get the “feel” of us-  
ing your saw before you begin a major  
sawing operation.  
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.  
Look for decay and ro.t If the trunk is rotted,  
it can snap and fall toward the operator.  
Make sure there is enough room for the tree to  
fall. Maintain a distance of 2-1/2 tree lengths  
from the nearest person or other objects. 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.

Squeeze the throttle trigger and allow the  
engine to reach full speed before cutting.  
Begin cutting with the saw frame  
against the log.  
Keep the engine at full speed the entire  
time you are cutting.  
Allow the chain to cut for you. Exert only  
light downward pressure.  
Release the throttle trigger as soon as  
the cut is completed, allowing the en-  
gine to idle. If you run the saw at full  
throttle without a cutting load, unneces-  
sary wear can occur.  
Plan a clear retreat path

(15 cm 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.

NOTCH CUT AND FELLING THE  
Important points  
S Cut only one log at a time.  
TREE  
S Cut shattered wood very carefully; sharp  
pieces of wood could be flung toward oper-  
ator.  
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.  
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.  
S Do not cut in an area where logs, limbs,  
and roots are tangled. Drag the logs into a  
clear area before cutting by pulling out ex-  
posed and cleared logs first.  
Final cut here. 5 cm above  
center of notch.

TYPES OF CUTTING USED FOR  
BUCKING  
Notch  
5 cm  
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. Do not  
attempt to restart your saw when it is pinched  
or hung in a log.  
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.  
Turn saw OFF and use a plastic or  
wooden wedge to force cut open.  
Overcutting begins on the top side of the log  
with the saw against the log. When overcut-  
ting use light downward pressure.  
Hinge holds tree on stump and helps  
control fall  
Opening  
of felling  
cut  
Overcutting  
Undercutting  
Closing of  
notch  
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.  
NOTE: Before felling cut is complete, use  
wedges to open the cut when necessary to  
control the direction of fall. To avoid kickback  
or 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.  
WARNING: Never turn saw upside  
down to undercut. The saw cannot be con-  
trolled in this position.  
S As tree starts to fall, stop saw, put it down,  
and get away quickly on your planned re-  
treat path.  
First cut on pressure side of log  
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.

CUTTING A FALLEN TREE  
(BUCKING)  
Bucking is the term used for cutting a fallen  
tree to the desired log length.  
First cut on pressure side of log  
BUCKING WITHOUT A  
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.  
SUPPORT  
S Overcut through 1/3 of the diameter of the  
log.

S Roll the log over and finish with a second  
overcut.  
S Give special attention to logs under strain  
to prevent the saw from pinching. Make  
the first cut on the pressure side to relieve  
the stress on the log.  
IMPORTANT POINTS  
S Watch out for springpoles. Use extreme  
caution when cutting small size limbs. Slen-  
der 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  
pressure side of the log.  
S Your first cut should extend 1/3 of the  
diameter of the log.  
S Keep a clear work area. Frequently clear  
branches out of the way to avoid tripping  
over them.  
S Finish with your second cut.

LIMBING  
S Always limb a tree after it is cut down. Only  
then can limbing be done safely and prop-  
erly.

Cut  
S Leave the larger limbs underneath the  
felled tree to support the tree as you work.  
S Start at base of the felled tree and work to-  
ward the top, cutting branches and limbs.  
Remove small limbs with one cut.  
S Keep the tree between you and the chain  
as much as possible.  
S Remove larger, supporting branches with  
the cutting techniques described in BUCK-  
ING WITHOUT A SUPPORT.

LIMBING AND PRUNING  
WARNING: Be alert for and guard  
against kickback. Do not allow the moving  
chain to contact any other branched or objects  
at the nose of the guide bar when limbing or  
pruning. Allowing such contact can result in  
serious injury.  
WARNING: Never climb into a tree to  
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.

evaporative emissions.  
Cleaning the air filter:  
A dirty air filter decreases engine perform-  
ance and increases fuel consumption and  
harmful emissions. Always clean after every  
5 hours of operation.  
SPARK PLUG  
The spark plug should be replaced each  
year to ensure the engine starts easier and  
runs better. Ignition timing is fixed and non-  
adjustable.

CHAIN SHARPENING  
STORAGE  
WARNING: Stop engine and allow to  
Chain sharpening is a complicated task that  
requires special tools. We recommend that  
you refer chain sharpening to a professional  
chain sharpener.  
cool, and secure the unit before storing or  
transporting in a vehicle. Store unit and fuel  
in an area where fuel vapors cannot reach  
sparks or open flames from water heaters,  
electric motors or switches, furnaces, etc.  
Store unit with all guards in place. Position so  
that any sharp object cannot accidentally  
cause injury to passersby. Store the unit out  
of reach of children.  
CARBURETOR ADJUSTMENTS  
WARNING: The chain will be moving  
during most of this procedure. Wear your pro-  
tective equipment and observe all safety pre-  
cautions. The chain must not move at idle  
speed.  
S Before storing, drain all fuel from the unit.  
Start engine and allow to run until it stops.  
S Clean the unit before storing. Pay particu-  
lar attention to the air intake area, keeping  
it free of debris. Use a mild detergent and  
sponge to clean the plastic surfaces.  
S Do not store the unit or fuel in a closed area  
where fuel vapors can reach sparks or an  
open flame from hot water heaters, electric  
motors or switches, furnaces, etc.  
The carburetor has been carefully set at the  
factory. Adjustments may be necessary if  
you notice any of the following conditions:  
S Chain moves at idle. See IDLE SPEED--T  
adjusting procedure.  
S Saw will not idle. See IDLE SPEED--T ad-  
justing procedure.  
Idle Speed-- T  
Allow engine to idle. If the chain moves, idle  
is too fast. If the engine stalls, idle is too slow.  
Adjust speed until engine runs without chain  
movement (idle too fast) or stalling (idle too  
slow). The idle speed screw is located in the  
area above the primer bulb and is labeled T.  
S Turn idle speed screw (T) clockwise to in-  
crease engine speed.  
S Store in a dry area out of the reach of chil-  
dren.  
CAUTION: It is important to prevent  
gum deposits from forming in essential fuel  
system parts such as the carburetor, fuel fil-  
ter, fuel hose, or fuel tank during storage. Al-  
cohol blended fuels (called gasohol or using  
ethanol or methanol) can attract moisture  
which leads to fuel mixture separation and  
formation of acids during storage. Acidic gas  
can damage the engine.  
S Turn idle speed screw (T) counterclock-  
wise to decrease engine speed.
