WARNING:
Read and understand all instructions. Failure to follow
all instructions listed below, may result in electric shock,
fire and/or serious personal injury.
READ ALL INSTRUCTIONS
Know your tool. Read the operator’s manual carefully.
Learn the saw’s applications and limitations as well as
the specific potential hazards related to this tool.
� Kickback may occur when the nose or tip of the guide
bar touches an object, or when the wood closes in and
pinches the saw chain in the cut. Tip contact in some
cases may cause a lightning-fast reverse reaction, kicking
the guide bar up and back toward the operator. Pinching
the saw chain along the top of the guide bar may push
the guide bar rapidly back toward the operator. Either of
these reactions may cause you to lose control of the saw,
which could result in serious personal injury. Do not rely
exclusively upon the safety devices built into the saw. As
a chain saw user, you should take several steps to keep
your cutting jobs free from accident or injury.
• With a basic understanding of kickback, you can
reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
• Keep a good firm grip on the saw with both hands when
the engine is running. Place your right hand on the rear
handle and your left hand on the front handle with your
thumbs and fingers encircling the chain saw handles.
A firm grip together with a stiff left arm will help you
maintain control of the saw if kickback occurs.
• Make sure that the area in which you are cutting is
free from obstructions. DO NOT let the nose of the
guide bar contact a log, branch, fence, or any other
obstruction that could be hit while you are operating
the saw.
• Cut at high engine speeds. Always cut with the engine
running at full speed. Fully squeeze the throttle trigger
and maintain a steady cutting speed.
• Do not overreach or cut above chest height.
• Follow the manufacturer’s sharpening and mainte-
nance instructions for the saw chain.
• Only use replacement bars and chains specified by
the manufacturer or the equivalent.
Do not operate a chain saw with one hand. Serious
injury to the operator, helpers, bystanders, or any com-
bination of these persons may result from one-handed
operation. A chain saw is intended for two-handed use.
Do not operate a chain saw when you are fatigued.
Fatigue causes carelessness. Be more cautious before
rest periods and towards the end of your shift. Never
operate a chain saw when you are tired or under the
influence of medication, drugs, or alcohol.
Use safety footwear. Wear snug-fitting clothing,
protective gloves, and eye, hearing, and head protection
devices.
Do not stand on any unstable surface while using the
chain saw, such as ladders, scaffolds, trees, etc.
Use caution when handling fuel. Move the chain saw
at least 30 feet from the fueling point before starting the
engine.
Do not allow other persons to be near the chain saw
when starting or cutting with the chain saw. Keep
bystanders and animals out of the work area.
Do not start cutting until you have a clear work area,
secure footing, and a planned retreat path from the falling
tree.
Keep all parts of your body away from the saw chain
when the engine is running.
Always carry the chain saw with the engine stopped
and the brake engaged, the guide bar and saw chain
to the rear, and the muffler away from your body. When
transporting the chain saw, use the appropriate guide bar
scabbard.
Do not operate a chain saw that is damaged, improp-
erly adjusted, or not completely and securely assembled.
Be sure that the saw chain stops moving when the throttle
control trigger is released.
� Shut off the engine before setting the chain saw
down. Do not leave the engine running unattended. As
an additional safety precaution, apply the chain brake
prior to setting down the saw.
� Use extreme caution when cutting small-size brush
and saplings because slender material may catch the
saw chain and be whipped toward you or pull you off
balance.
� When cutting a limb that is under tension, be alert for
springback so that you will not be struck when the tension
in the wood fibers is released.
� Keep the handles dry, clean, and free of oil or fuel
mixture.
Beware of carbon monoxide poisoning. Operate the
chain saw only in well-ventilated areas.
� Do not operate a chain saw in a tree unless you have
been specifically trained to do so.
Do not cut from a ladder; this is extremely dangerous.
All chain saw service, other than the items listed in
the instruction manual and all maintenance, should be
performed by competent chain saw service personnel.
(For example, if improper tools are used to remove the
flywheel or if an improper tool is used to hold the flywheel
in order to remove the clutch, structural damage to the
flywheel could occur and subsequently could cause the
flywheel to burst.)
Always have a fire extinguisher available when using
chain saw.
Use only the replacement guide bars and low kickback
chains specified for the saw.
GENERAL SAFETY RULES
4
WARNING:
The warnings, labels, and instructions found in this sec-
tion of the operator’s manual are for your safety. Failure
to follow all instructions may result in serious personal
injury.
Do not cut vines and/or small underbrush (a diameter
of less than 3 in.).
Muffler surfaces are very hot during and after opera-
tion of the chain saw; keep all body parts away from
the muffler. Serious burns may occur if contact is made
with the muffler.
� Always hold the chain saw with both hands when
the engine is running. Use a firm grip with thumbs and
fingers encircling the chain saw handles.
� Never let anyone use the chain saw who has not
received adequate instructions in its proper use. This
applies to rentals as well as privately owned saws.
� Before you start the engine, make sure the saw chain
is not contacting any object.
Wear snug-fitting clothing. Always wear heavy long
pants, boots, and gloves. Do not wear jewelry, short
pants, sandals, or go barefoot. Do not wear loose fitting
clothing, which could be drawn into the engine or catch
the chain or underbrush. Wear overalls, jeans, or chaps
made of cut-resistant material or ones that contain cut-
resistant inserts. Secure hair so that it is above shoulder
level.
� Wear non-slip safety footwear and heavy-duty gloves
to improve your grip and to protect your hands.
� Wear eye protection which is marked to comply with
ANSI Z87.1, as well as hearing and head protection,
when operating this equipment.
Keep bystanders and animals out of the work area.
Do not allow other persons to be nearby during starting
or cutting with the chain saw.
NOTE: The size of the work area depends on the job being
performed as well as the size tree or workpiece involved.
For example, felling a tree requires a larger work area than
making other cuts (i.e., bucking cuts, etc.).
Keep SAFE-T-TIP anti-kickback nose guard properly
mounted on the guide bar to prevent rotational kick-
back.
Follow the sharpening and maintenance instructions
for the saw chain.
Never operate a chain saw that is damaged, improp-
erly adjusted, or is not completely and securely
assembled. Be sure that the saw chain stops moving
when the throttle control trigger is released. If the saw
chain moves at idle speed, the carburetor may need
adjusting. Refer to Adjusting the Carburetor in the
Maintenance section of this manual. If the saw chain still
moves at idle speed after adjustment has been made,
contact an authorized service center for adjustment and
discontinue use until the repair is made.
REFUELING (DO NOT SMOKE!)
� To reduce the risk of fire and burn injury, handle fuel
with care. It is highly flammable.
� Mix and store fuel in a container approved for gaso-
line.
� Mix fuel outdoors where there are no sparks or
flames.
� Select bare ground, stop the engine, and allow it to
cool before refueling.
� Loosen the fuel cap slowly to release pressure and to
keep fuel from escaping around the cap.
� Tighten the fuel cap securely after refueling.
� Wipe spilled fuel from the unit. Move 30 feet away from
refueling site before starting engine.
Never attempt to burn off spilled fuel under any cir-
cumstances.
KICKBACK
Kickback is a dangerous reaction that can lead to
serious injury. Do not rely only on the safety devices
provided with the saw. As a chain saw user, you must
take special safety precautions to help keep your cut-
ting jobs free from accident or injury. See the General
Safety Rules and Operation sections of this manual for
added information on kickback and how to avoid serious
personal injury.
� Do not adapt the powerhead to a bow guide or use it
to power any attachments or devices not listed for the
saw.
� The gas powered saw (or electrically powered saw)
is classified by CSA as a Class 1C (or Class 2C) saw.
It is intended for infrequent use by homeowners, cottag-
ers, and campers, and for such general applications as
clearing, pruning, cutting firewood, etc. It is not intended
for prolonged use. Prolonged periods of operation can
cause circulatory problems in the user’s hands due to
vibration. For such use, it may be appropriate to use a
saw having an anti-vibration feature.

ADJUSTING IDLE SPEED
See Figure 13.
If the engine starts, runs, and accelerates, but will not
idle, turn the idle speed screw “T” clockwise to increase
idle speed.
If the chain turns at idle, turn the idle speed screw “T”
counterclockwise to reduce the idle RPM and stop the
chain movement. If the saw chain still moves at idle speed,
contact an authorized service center for adjustment and
discontinue use until the repair is made.
WARNING:
THE SAW CHAIN SHOULD NEVER TURN AT IDLE. Turn
the idle speed screw “T” counterclockwise to reduce the
idle RPM and stop the chain, or contact an authorized
service center for adjustment and discontinue use until
the repair is made. Serious personal injury may result
from the saw chain turning at idle.
PULL AND PUSH
See Figure 14.
The reaction force of the saw is always opposite to the direc-
tion the chain is moving. Thus, the operator must be ready
to control the PULL when cutting on the bottom edge of the
bar and the PUSH when cutting along the top edge.
NOTE: The chain saw has been fully factory tested. It is
normal to find some slight oil residue on the saw.
WARNING:
KICKBACK occurs when the moving chain contacts an
object at the upper portion of the tip of the guide bar or
when the wood closes in and pinches the saw chain in the
cut. Contact at the upper portion of the tip of the guide
bar can cause the chain to dig into the object and stop the
chain for an instant. The result is a lightning-fast reverse
reaction which kicks the guide bar up and back toward
the operator. If the saw chain is pinched along the top of
the guide bar, the guide bar can be driven rapidly back
toward the operator. Either of these reactions can cause
loss of saw control, which can result in serious injury.
Do not rely exclusively upon the safety devices built
into the saw. As a chain saw user, you should take
steps to keep your cutting jobs free from accident or
injury. See General Safety Rules for more details.

KICKBACK PRECAUTIONS
See Figures 15 - 16.
Rotational kickback occurs when the moving chain contacts
an object at the Kickback Danger Zone of the guide bar. The
result is a lightning-fast reverse reaction, which kicks the
guide bar up and back towards the operator. This reaction can
cause loss of control, which can result in serious injury.
PREPARING FOR CUTTING
PROPER GRIP ON HANDLES
See Figure 17.
See General Safety Rules for appropriate safety equipment.
Wear non-slip gloves for maximum grip and protection.
Hold the saw firmly with both hands. Always keep your
left hand on the front handle and your right hand on the
rear handle so that your body is to the left of the chain
line.
WARNING:
Never use a left-handed (cross-handed) grip or any
stance that would place your body or arm across the
chain line.
Maintain a proper grip on the saw whenever the engine
is running. The fingers should encircle the handle and the
thumb is wrapped under the handlebar. This grip is least
likely to be broken by a kickback or other sudden reaction
of the saw. Any grip in which the thumb and fingers are
on the same side of the handle is dangerous because a
slight kick of the saw can cause loss of control.

Keep your thumb on underside of handlebar.
WORK AREA PRECAUTIONS
See Figure 19.
Cut only wood or materials made from wood; no sheet
metal, no plastics, no masonry, no non-wood building
materials.
Never allow children to operate the saw. Allow no person
to use this chain saw who has not read this operator’s
manual or received adequate instructions for the safe and
proper use of this chain saw.
Keep everyone – helpers, bystanders, children, and ani-
mals, a SAFE DISTANCE from the cutting area. During
felling operations, the safe distance should be a least
twice the height of the largest trees in the felling area.
During bucking operations, keep a minimum distance of
15 feet between workers.
Always cut with both feet on solid ground to prevent being
pulled off balance.
Do not cut above chest height as a saw held higher is
difficult to control against kickback forces.
Do not fell trees near electrical wires or buildings. Leave
this operation for professionals.
Cut only when visibility and light are adequate for you to
see clearly.
BASIC OPERATING/CUTTING PROCEDURES
Practice cutting a few small logs using the following technique
to get the “feel” of using the saw before you begin a major
sawing operation.
Take the proper stance in front of the wood with the saw
idling.
Accelerate the engine to full throttle just before entering
the cut by squeezing the throttle trigger.
Begin cutting with the saw against the log.
Keep the engine at full throttle the entire time you are
cutting.
Allow the chain to cut for you; exert only light downward
pressure. Forcing the cut could result in damage to the
bar, chain, or engine.
Release the throttle trigger as soon as the cut is com-
pleted allowing the engine to idle. Running the saw at full
throttle without a cutting load can result in unnecessary
wear to the chain, bar, and engine.
Do not put pressure on the saw at the end of the cut.

FELLING TREES
HAZARDOUS CONDITIONS
WARNING:
Do not fell trees during periods of high wind or heavy
precipitation. Wait until the hazardous weather has
ended.
When felling a tree, it is important that you heed the following
warnings to prevent possible serious injury.
� Do not cut down trees having an extreme lean or large
trees with rotten limbs, loose bark, or hollow trunks. Have
these trees pushed or dragged down with heavy equip-
ment, then cut them up.
� Do not cut trees near electrical wires or buildings.
� Check the tree for damaged or dead branches that could
fall and hit you during felling.
� Periodically glance at the top of the tree during the
backcut to assure the tree is going to fall in the desired
direction.
If the tree starts to fall in the wrong direction, or if the saw
gets caught or hung up during the fall, leave the saw and
save yourself!
PROPER PROCEDURE FOR TREE FELLING
See Figures 20 - 23.
Pick your escape route (or routes, in case the intended
route is blocked). Clear the immediate area around the
tree and make sure there are no obstructions in your
planned path of retreat. Clear the path of safe retreat
approximately 135° from the planned line of fall.
Consider the force and direction of the wind, the lean
and balance of the tree, and the location of large limbs.
These things influence the direction in which the tree will
fall. Do not try to fell a tree along a line different from its
natural line of fall.
Cut a notch about 1/3 the diameter of the trunk in the
side of the tree. Make the notch cuts so they intersect
at a right angle to the line of fall. This notch should be
cleaned out to leave a straight line. To keep the weight
of the wood off the saw, always make the lower cut of
the notch before the upper cut.
Make the backcut level and horizontal, and at a minimum
of 2 in. above the horizontal cut of the notch.
NOTE: Never cut through to the notch. Always leave a
band of wood between the notch and back cut (approxi-
mately 2 in. or 1/10 the diameter of the tree). This is called
“hinge” or “hingewood.” It controls the fall of the tree and
prevents slipping or twisting or shootback of the tree off
the stump.

On large diameter trees, stop the back cut before it is
deep enough for the tree to either fall or settle back on
the stump. Then insert soft wooden or plastic wedges into
the cut so they do not touch the chain. Drive wedges in,
little by little, to help jack the tree over.
When bucking or felling with a wedge, it may be necessary
to remove the SAFE-T-TIP anti-kickback device to allow
the bar to be drawn through the cut. After you complete
the cut, reinstall the tip immediately.
As tree starts to fall, stop the chain saw and put it down
immediately. Retreat along the cleared path, but watch
the action in case something falls your way.
WARNING:
Never cut through to the notch when making a back cut.
The hinge controls the fall of the tree, this is the section
of wood between the notch and backcut.
REMOVING BUTTRESS ROOTS
See Figure 24.
A buttress root is a large root extending from the trunk of the
tree above the ground. Remove large buttress roots prior to
felling. Make the horizontal cut into the buttress first, followed
by the vertical cut. Remove the resulting loose section from
the work area. Follow the correct tree felling procedure as
stated in Proper Procedure For Tree Felling after you have
removed the large buttress roots.
BUCKING
See Figure 25.
Bucking is the term used for cutting a fallen tree to the
desired log length.
Cut only one log at a time.
Support small logs on a saw horse or another log while
bucking.
Keep a clear cutting area. Make sure that no objects
can contact the guide bar nose and chain during cutting,
this can cause kickback. To avoid the danger, keep the
SAFE-T-TIP anti-kickback device attached while cutting.
Refer to Kickback in the Specific Safety Rules section of
this manual for more information.
� During bucking operations, stand on the uphill side so
that the cut-off section of the log cannot roll over you.
� Sometimes it is impossible to avoid pinching (with just
standard cutting techniques) or difficult to predict which
way a log will settle when cut.

OPERATION
19
BUCKING WITH A WEDGE
See Figure 26.
If the wood diameter is large enough for you to insert a soft
bucking wedge without touching the chain, you should use
the wedge to hold the cut open to prevent pinching.
NOTE: When bucking or felling with a wedge, you may need
to remove the SAFE-T-TIP anti-kickback device to allow the
bar to be drawn through the cut. After you complete the cut,
reinstall the tip.
BUCKING LOGS UNDER STRESS
See Figure 27.
Make the first bucking cut 1/3 of the way through the log
and finish with a 2/3 cut on the opposite side. As you cut
the log, it will tend to bend. The saw can become pinched
or hung in the log if you make the first cut deeper than 1/3
of the diameter of the log.
Give special attention to logs under stress to prevent the
bar and chain from pinching.
OVERBUCKING
See Figure 28.
Begin on the top side of the log with the bottom of the saw
against the log; exert light pressure downward. Note that
the saw will tend to pull away from you.

UNDERBUCKING
See Figure 29.
Begin on the underside of the log with the top of the saw
against the log; exert light pressure upward. During under-
bucking, the saw will tend to push back at you. Be prepared for
this reaction and hold the saw firmly to maintain control.
LIMBING AND PRUNING
See Figures 30 - 31.
Work slowly, keeping both hands on the saw with a firm
grip. Maintain secure footing and balance.
� Keep the tree between you and the chain while limbing.
Do not cut from a ladder. This is extremely dangerous.
Leave this operation for professionals.
� Do not cut above chest height. A saw held higher than
chest height is difficult to control against kickback.
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.
� When pruning trees it is important not to make the flush
cut next to the main limb or trunk until you have cut off
the limb further out to reduce the weight. This prevents
stripping the bark from the main member.
• Underbuck the branch 1/3 through for your first cut.
• Overbuck the branch to drop it.
• Finish by cutting smoothly and neatly against the
main member so the bark will grow back to seal the
wound.
WARNING:
If the limbs to be pruned are above chest height, hire a
professional to perform the pruning.
CUTTING SPRINGPOLES
See Figure 32.
A springpole is any log, branch, rooted stump, or sapling
which is bent under tension by other wood so that it springs
back if the wood holding it is cut or removed. On a fallen
tree, a rooted stump has a high potential of springing back
to the upright position during the bucking cut to separate
the log from the stump. Watch out for springpoles — they
are dangerous.
WARNING:
Springpoles are dangerous and could strike the operator,
causing the operator to lose control of the chain saw. This
could result in severe or fatal injury to the operator.

NOTE: During normal saw operation, the temperature
of the chain increases. The drive links of a correctly ten-
sioned warm chain will hang approximately .050 in. out
of the bar groove. The tip of the combination wrench can
be used as a guide to help determine the correct warm
chain tension.
NOTE: New chains tend to stretch; check the chain ten-
sion frequently and tension as required.
CAUTION:
A chain tensioned while warm may be too tight upon
cooling. Check the “cold tension” before next use.
CHAIN MAINTENANCE
See Figures 46 - 47.
CAUTION:
Check that the switch is in the STOP “ ” position before
you work on the saw.
Use only a low-kickback chain on this saw. This fast-
cutting chain provides kickback reduction when properly
maintained.
For smooth and fast cutting, maintain the chain properly.
The chain requires sharpening when the wood chips are
small and powdery, the chain must be forced through the
wood during cutting, or the chain cuts to one side. During
maintenance of the chain, consider the following:
� Improper filing angle of the side plate can increase the
risk of severe kickback.
Raker (depth gauge) clearance.
• Too low increases the potential for kickback.
• Not low enough decreases cutting ability.
If the cutter teeth hit hard objects such as nails and
stones, or are abraded by mud or sand on the wood,
have an authorized service center sharpen the chain.
NOTE: Inspect the drive sprocket for wear or damage
when replacing the chain. If signs of wear or damage are
present in the areas indicated, have the drive sprocket
replaced by an authorized service center.
NOTE: If you do not fully understand the correct procedure
for sharpening the chain after reading the instructions that
follow, have the saw chain sharpened by an authorized
service center or replace with a recommended low-kickback
chain.

SHARPENING THE CUTTERS
See Figures 48 - 51.
Be careful to file all cutters to the specified angles and to
the same length, as fast cutting can only be obtained when
all cutters are uniform.
WARNING:
The saw chain is very sharp. Always wear protective
gloves when performing maintenance to the chain to
prevent serious personal injury.
Tension the chain prior to sharpening. Refer to Adjusting
The Chain Tension.
Use a 5/32 in. diameter round file and holder. Do all of
your filing at the midpoint of the bar.
Keep the file level with the top plate of the tooth. Do not
let the file dip or rock.
Using light but firm pressure. Stroke towards the front
corner of the tooth.
Lift the file away from the steel on each return stroke.
Put a few firm strokes on every tooth. File all left hand
cutters in one direction. Then move to the other side and
file the right hand cutters in the opposite direction.
Remove filings from the file with a wire brush.
CAUTION:
A dull or improperly sharpened chain can cause exces-
sive engine speed during cutting, which may result in
severe engine damage.
WARNING:
Improper chain sharpening increases the potential of
kickback.
WARNING:
Failure to replace or repair a damaged chain can cause
serious injury.

clearance.
� Use a flat file and a depth gauge jointer to lower all gauges
uniformly. Use a .025 in. depth gauge jointer. After lower-
ing each depth gauge, restore original shape by rounding
the front. Be careful not to damage adjoining drive links
with the edge of the file.
� Depth gauges must be adjusted with the flat file in the
same direction the adjoining cutter was filed with the
round file. Use care not to contact cutter face with flat
file when adjusting depth gauges.
MAINTENANCE

MAINTAINING THE GUIDE BAR
See Figure 57.
CAUTION:
Make sure the chain has stopped before you do any work
on the saw.
Every week of use, reverse the guide bar on the saw to
distribute the wear for maximum bar life. The bar should
be cleaned every day of use and checked for wear and
damage.
Feathering or burring of the bar rails is a normal process of
bar wear. Such faults should be smoothed with a file as soon
as they occur. While the guide bar is unmounted, remove
sawdust in the bar groove and the lubricating hole.
A bar with any of the following faults should be replaced:
Wear inside the bar rails that permits the chain to lay over
sideways
Bent guide bar
Cracked or broken rails
Spread rails
Lubricate guide bars weekly with a sprocket at their tip.
Using a grease syringe, lubricate weekly in the lubricating
hole. Turn the guide bar and check that the lubrication holes
and chain groove are free from impurities.
MOUNTING THE SAFE-T-TIP NOSE GUARD
See Figures 58 - 59.
Mount the SAFE-T-TIP on the bar nose.
Fit the locking rivet or tab in the recessed hole in the guide
bar.
Tighten the screw with wrench until snug.
From the snug position, tighten the screw an additional
1/4 of a turn using a wrench.
MAINTAINING THE SAFE-T-TIP NOSE GUARD
See Figures 58 - 59.
CAUTION:
Make sure the chain has stopped before you do any work
on the saw.
WARNING:
Although the guide bar comes with a SAFE-T-TIP anti-
kickback device already installed, check the tightness of
the mounting screw before each use.
Use the following instructions to tighten the mounting screw
of the nose guard. These are specially hardened screws. If
you cannot install the screw tightly, replace both the screw
and the SAFE-T-TIP before further operation.

NOTE: Do not replace the screw with an ordinary screw.
Use only identical replacement parts from the manufacturer
when replacing parts.
In addition to preventing chain contact with solid objects at
the nose of the bar, the SAFE-T-TIP also helps keep the chain
away from abrasive surfaces, such as the ground. Keep it on
the right hand side of the bar where it will be between the
chain and the ground during flush-with-ground cutting.
The mounting screw requires a 5/16 in. wrench (or adjust-
able wrench) to achieve the recommended torque of 35 to
45 in.lb. A torque within this range can be achieved by using
the following method.
Tighten the screw with wrench until snug.

CARBURETOR ANTI-FREEZE MECHANISM
See Figures 65 - 66.
The chain saw is designed with a ventilation hatch on the
right side of the cylinder cover which allows warm air to be
supplied from the engine to the carburetor to help prevent
icing under colder operating conditions. Operating the
chain saw in temperatures from 32ºF to 41ºF (0ºC to 5ºC)
at times of high humidity may result in ice forming within the
carburetor. This can cause the output power of the engine
to be reduced and/or the engine to fail to operate smoothly.
When operating under these circumstances, the chain saw
should be placed in anti-freeze mode before use.
To switch to anti-freeze mode:
Place the ignition switch in the OFF ( )position.
Remove the air cleaner cover.
Remove the air cleaner.
Lift choke knob up to remove from the cylinder cover.
Loosen the five screws holding the cylinder cover in place.
Remove the cylinder cover.
Remove the icing cap located on the right-hand side of the
cylinder cover by pressing down on it with your finger.
Adjust the icing cap so that the “snow” mark faces
upward, then return it to its original position in the cylinder
cover.
Replace the cylinder cover and reinstall screws to
secure.
Replace choke knob, air cleaner, and air cleaner cover.
WARNING
Always return the unit to normal operating mode if there
is no danger of icing occurring. Continuing to use the
chain saw in anti-freeze mode when temperatures have
risen and returned to normal may result in the engine
failing to start properly or in the engine failing to operate
at its normal speed.
CLEANING THE ENGINE
See Figures 67 - 68.
Clean the cylinder fins and flywheel fins with compressed air
or a brush periodically. Dangerous overheating of the engine
may occur due to impurities on the cylinder.
WARNING
Never run the saw without all the parts, including the
drivecase cover and starter housing, securely in place.
Because parts can fracture and pose a danger of thrown
objects, leave repairs of the flywheel and clutch to factory
trained authorized service center personnel.

replacement and replace every 50 hours or more frequently,
if necessary.
Loosen the spark plug by turning it counterclockwise with
a wrench.
Remove the spark plug.
Hand thread the new spark plug, turning it clockwise.
Tighten securely with wrench.
NOTE: Be careful not to cross-thread the spark plug.
Cross-threading will seriously damage the cylinder.
INSPECTING/CLEANING THE SPARK
ARRESTOR SCREEN AND MUFFLER
EXHAUST PORT
See Figure 71.
The muffler is equipped with a spark arrestor screen. A faulty
spark arrestor screen can create a fire hazard. Through normal
use the screen can become dirty and should be inspected
weekly and cleaned as required. Always keep the muffler
and spark arrestor on the saw in good condition.
WARNING
Muffler surfaces are very hot during and after operation
of the chain saw. To avoid serious personal injury, keep
all body parts away from the muffler.
Allow the muffler to cool.
Remove torx screw and 5/16 in. nuts holding the muffler
cover in place; remove muffler cover and spark screen.
If dirty, clean the spark arrestor screen with a small wire
brush. Replace the screen if it is cracked or otherwise
deteriorated.
Remove the muffler.
Insert a flat blade screwdriver into the muffler exhaust
vent to remove any carbon deposits.
Wipe away any carbon buildup on the muffler exhaust
vent and the cylinder exhaust port at the same time.
Reinstall muffler, spark screen, and muffler cover.
Reinstall torx screw and nuts to secure.

INSPECTING AND CLEANING CHAIN BRAKE
See Figures 72 - 73.
Remove the clutch cover and clean the chain brake com-
ponents. Check wear on the brake band and replace if
worn or deformed. The band thickness should not be less
than 0.024 in., or worn halfway through.
Always keep the chain brake mechanism clean and lightly
lubricate the linkage.
Always test the chain brake performance after servicing or
cleaning. Refer to Operating Chain Brake for additional
information.
Check the chain catcher and replace if damaged.
WARNING:
Even with daily cleaning of the mechanism, the depend-
ability of a chain brake to perform under field conditions
cannot be certified. Keep the SAFE-T-TIP nose guard on
the saw’s guide bar and use proper cutting techniques.
STORING THE CHAIN SAW (1 MONTH OR
LONGER)
Drain all fuel from tank into a container approved for
gasoline.
Run the engine until it stops. This will remove all fuel-oil
mix that could become stale and leave varnish and gum
in the fuel system.
Squeeze primer bulb several times to purge fuel from
carburetor.
Drain all bar and chain oil from tank into a container
approved for oil.
Clean all foreign material from the saw.
Store it in a well-ventilated place that is inaccessible to
children.
NOTE: Keep away from corrosive agents such as garden
chemicals and de-icing salts.
Abide by all federal and local regulations for the safe storage
and handling of gasoline. Excess fuel should be used in other
2-cycle engine powered equipment.

WARRANTY
THE FOLLOWING CALIFORNIA AIR RESOURCES BOARD (CARB) STATEMENT ONLY APPLIES
TO MODEL NUMBERS REQUIRED TO MEET THE CARB REQUIREMENTS.
TECHTRONIC INDUSTRIES NORTH AMERICA, INC., LIMITED WARRANTY
FEDERAL AND CALIFORNIA EMISSION CONTROL SYSTEMS NON-ROAD AND SMALL
OFF-ROAD ENGINES
The U.S. Environmental Protection Agency (EPA), the California Air Resources Board (CARB), and Techtronic Industries North America, Inc.,
are pleased to explain the Emission Control System Warranty on your non-road or small off-road engine. In California, new small off-road
engines must be designed, built, and equipped to meet the state’s stringent anti-smog standards. In other states, new 2000 and later model
year non-road engines must be designed, built, and equipped at the time of sale to meet the U.S. EPA regulations for small non-road engines.
The non-road engine must be free from defects in materials and workmanship which cause it to fail to conform with U.S. EPA standards for
the first two years of engine use from the date of sale to the ultimate purchaser. Techtronic Industries North America, Inc., must warrant the
emission control system on your non-road or small off-road engine for the period of time listed above provided there has been no abuse,
neglect, or improper maintenance of your non-road or small off-road engine.
Your emission control system may include parts such as the carburetor or fuel injection system, the ignition system, and the catalytic con-
verter. Also included may be hoses, belts and connectors, and other emission-related assemblies.
Where a warrantable condition exists, Techtronic Industries North America, Inc., will repair your non-road or small off-road engine at no
cost to you, including diagnosis (if the diagnostic work is performed at an authorized service center for RYOBI® brand outdoor products),
parts, and labor.
MANUFACTURER’S WARRANTY COVERAGE:
The 1995 and later small off-road engines are warranted for two years in California. In other states, 1997 and later model year non-road
engines are also warranted for two years. If any emission-related part on your engine is defective, the part will be repaired or replaced by
Techtronic Industries North America, Inc., free of charge.
OWNER’S WARRANTY RESPONSIBILITIES
(a) As the non-road or small off-road engine owner, you are responsible for the performance of required maintenance listed in your operator’s
manual. Techtronic Industries North America, Inc., recommends that you retain all receipts covering maintenance on your non-road or
small off-road engine, but Techtronic Industries North America, Inc., cannot deny warranty solely for the lack of receipts or for your
failure to ensure the performance of all scheduled maintenance. Any replacement part or service that is equivalent in performance and
durability may be used in non-warranty maintenance or repairs, and shall not reduce the warranty obligations of the engine manufacturer.
(b) As the non-road or small off-road engine owner, you should be aware, however, that Techtronic Industries North America, Inc., may deny you
warranty coverage if your non-road or small off-road engine or a part has failed due to abuse, neglect, improper maintenance, or unap-
proved modifications.
(c) You are responsible for presenting your non-road or small off-road engine to an authorized service dealer as soon as a problem exists.
The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.
If you have any questions regarding your warranty rights and responsibilities, you should contact a Techtronic Industries North America,
Inc., Customer Representative at 1-800-860-4050.
COVERAGE:
Techtronic Industries North America, Inc., warrants to the ultimate purchaser and each subsequent purchaser that your non-road or small
off-road engine will be designed, built, and equipped at the time of sale, to meet all applicable regulations. Techtronic Industries North
America, Inc., also warrants to the initial purchaser and each subsequent purchaser that your non-road or small off-road engine is free from
defects in materials and workmanship which cause the engine to fail to conform with applicable regulations for a period of two years. The
1995 and later small off-road engines are warranted for two years in California. In all other states for 1997 and later model years, EPA requires
manufacturers to warrant non-road engines for two years. These warranty periods will begin on the date the non-road or small off-road
engine is purchased by the initial purchaser. If any emission-related part on your engine is defective, the part will be replaced by Techtronic
Industries North America, Inc., at no cost to the owner.
Techtronic Industries North America, Inc., shall remedy warranty defects at any authorized RYOBI engine dealer or warranty sta-
tion. Any authorized work done at an authorized dealer or warranty station shall be free of charge to the owner if such work deter-
mines that a warranted part is defective. Any manufacturer-approved or equivalent replacement part may be used for any warranty
maintenance or repairs on emission-related parts, and must be provided free of charge to the owner if the part is still under warranty. Tech-
tronics North America, Inc., is liable for damages to other engine components caused by the failure of a warranted part still under warranty.
The California Air Resources Board’s Emission Warranty Parts List specifically defines the emission-related warranted parts. (EPA’s regula-
tions do not include a parts list, but EPA considers emission-related warranted parts to include all the parts listed below.)
These warranted parts are: Carburetor, Spark Plug, Ignition, Air Filter, and Fuel Filter.
MAINTENANCE REQUIREMENTS
The owner is responsible for the performance of the required maintenance as defined by Techtronic Industries North America, Inc., in the
operator’s manual.
LIMITATIONS
The Emission Control Systems Warranty shall not cover any of the following:

ments not conforming to Techtronic Industries North America, Inc., specifications that adversely affect performance and/or durability,
and alterations or modifications not recommended or approved in writing by Techtronic Industries North America, Inc., and
(b) replacement of parts and other services and adjustments necessary for required maintenance at and after the first scheduled replace-
ment point.
