spilled fuel from the unit immediately, before starting the unit.
Move the unit at least 30 ft. (9.1 m) from the fueling source and
site before starting the engine. DO NOT smoke.
Never start or run the unit inside a closed room or building.
Breathing exhaust fumes can kill. Operate this unit only in a well
ventilated outdoor area.
WHILE OPERATING
Wear safety glasses or goggles that meet current ANSi Z87.1
standards and are marked as such. Wear ear/hearing protection
when operating this unit. Wear a face mask or dust mask if the
operation is dusty. Use a hard hat or other type of safety helmet.
Wear safety boots and protective gloves. Wear heavy, snug-
fitting clothes, including long pants and a long-sleeve shirt. Do
not wear loose clothing, jewelry, short pants, sandals or go
barefoot. Secure hair above shoulder level.
Make sure the saw chain is not in contact with anything before
starting the unit.
Use the unit only in daylight or good artificial light.
Avoid accidental starting. Be in the starting position whenever
pulling the starter rope. The operator and unit must be in a stable
position while starting. Refer to Starting and Stopping.
Use the right tool. Only use this tool for its intended purpose: to
cut wood. Do not use the unit for cutting plastic, masonry or
other non-wood building materials. Only use the unit as
described in this manual.
Keep all body parts away from the saw chain when the unit is
running. Do not touch or try to stop moving parts.
Do not touch the engine or muffler. These parts get extremely hot
from operation, even after the unit is turned off.
Do not operate the unit faster than the speed needed to do the job.
Do not run the unit at high speed when not in use.
Do not force the unit, especially near the end of a cut. It will do a
better, safer job when used at the intended rate.
Always turn the engine off when operation is delayed, when
setting the unit down or when carrying the unit from one location
to another. Make sure all moving parts come to a complete stop.

before repairing damage. Do not operate the unit with loose or
damaged parts.
Use only original equipment manufacturer (OEM) replacement
parts and accessories for this unit. These are available from a
Sears or other qualified service dealer. Use of any other parts or
accessories could lead to serious injury to the user, or damage
to the unit, and void the warranty.
Keep the unit clean. Carefully remove vegetation and other
debris that could block moving parts.
To reduce fire hazard, replace a faulty muffler and spark arrestor.
Keep the engine and muffler free from grass, leaves, excessive
grease or carbon build up.
If the unit starts to vibrate abnormally, stop the unit immediately.
Inspect the unit for the cause of the vibration. Vibration is
generally an indicator of trouble.
Keep the work area clean. Cluttered areas invite injuries. Do not
start cutting until the work area is clear and free from
obstructions. Make sure there is secure footing and a planned
retreat path from falling trees or branches.
Do not cut near electrical cables or power lines. Keep at least 50
feet (15 m) away from all power lines.
For safer, more effective performance, make sure the guide bar
and chain are properly cleaned, lubricated, tightened and
sharpened. Check the guide bar and chain at frequent intervals
for proper adjustment.
When cutting a limb that is under tension, use extreme caution.
When the tension is released, the limb could spring back and
strike the operator, causing severe injury or death.

KICKBACK SAFETY
WARNING: 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. In
some cases, tip contact may cause a lightening-fast
reverse action, kicking the guide bar rapidly back towards
the operator. Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly back towards the
operator. Either of these reactions may cause a loss of
control over the saw, which could result in serious injury to
the user. Contact with foreign objects within the wood can
also induce a loss of chain saw control.
Understanding Kickback
A basic understanding of kickback can help reduce or eliminate the
element of surprise and the chance of kickback-related injury.
Sudden surprise contributes to accidents.
• Rotational Kickback can happen when the upper tip of the
guide bar contacts an object while the chain is moving (Fig. A).
This can cause the chain to dig into the object and momentarily
stop moving. The guide bar is then kicked up and back toward
the operator in a lightning-fast reverse reaction.
• Linear Kickback can happen when the wood on either side of a
cut closes in and pinches the moving saw chain along the top of
the guide bar (Fig. B). This can cause the chain to instantly stop.
The chain force is then reversed, causing the saw to move in the
opposite direction, sending the saw straight back toward the
operator.
• Pull-In can happen when the moving chain on the bottom of the
guide bar hits a foreign object inside the wood. This can cause
the chain to suddenly stop. The saw is then pulled forward and
away from the operator, which could potentially result in the loss
of control of the saw.

Kickback Safety Precautions
Take the following steps to reduce the chance of accident or injury:
Do not rely exclusively upon the safety devices built into the unit.
Do not cut above shoulder height.
Do not overreach. Always keep proper footing and balance. Take
extra care when working on steep slopes or inclines.
Do not make cuts with the tip of the guide bar.
Make sure the area of operation is free from obstructions. Do not
let the tip of the guide bar contact any object, such as a log,
branch, the ground or other obstruction.
Always inspect the wood before cutting. Foreign objects could
damage the unit or cause serious personal injury. Never cut
through nails, metal rods, railroad ties or pallets.
Do not operate the unit with one hand! Serious injury to the
operator, helpers or bystanders may result from one-handed
operation. This unit is intended for two-handed use. Always grip
the unit firmly with both hands when the unit is running. Hold the
front handle with the left hand and the rear handle with the right
hand. Firmly encircle the handles with the thumbs and fingers.
Do not let go. A firm grip will help maintain control of the unit
and reduce the chance of kickback.
Stand slightly to the left of the unit to avoid being in the direct
line of the saw chain.
Never start the saw when the guide bar is inside an existing cut.
Be extremely careful when re-entering a cut.
Always begin a cut with the unit running at full speed. Fully
squeeze the throttle control and maintain a steady cutting
speed. Slower speeds increase the chance of kickback.
Keep the saw housing pressed firmly against the wood.
Do not cut more than one log or branch at a time.
Do not twist the unit when removing the guide bar from a cut.
Watch out for shifting objects (logs, branches, etc.) that might
pinch or fall onto the saw chain during operation.

SAFETY FEATURES
• LOW-KICKBACK SAW CHAIN significantly reduces the chance of kickback and the intensity of kickback, due to specially designed
depth gauges and guard links.
The SPARK ARRESTER SCREEN retains carbon and other flammable particles over 0.023 inches (0.6ram) in size from the engine
exhaust flow. Compliance with local, state and federal laws and/or regulations governing the use of a spark arrester screen is the user's
responsibility. Refer to Spark Arrestor Note in the Safety section for additional information.
The CHAIN BRAKE LEVER / FRONT HAND GUARD helps protect the operator's left hand if it slips off the front handle while the unit is
running. The chain brake lever is also used to manually engage the chain brake.
The CHAIN BRAKE reduces the chance of injury if kickback occurs, by stopping the saw chain in milliseconds. The chain brake is
designed to engage automatically in response to kickback. The chain brake can also be activated by pushing the chain brake lever
forward, either intentionally or if the operator's hand strikes the lever during kickback.
The ON/OFF SWITCH immediately stops the engine when moved to the OFF position. The On/Off switch must be moved to the On
position to start the engine.
The THROTTLE LOCKOUT prevents accidental acceleration of the engine. The throttle control cannot be squeezed unless the throttle
lockout is depressed.
The CHAIN CATCHER reduces the chance of injury if the saw chain breaks or derails during operation. The chain catcher is designed to
intercept a whipping chain.

OiL AND FUEL MiXiNG iNSTRUCTiONS
The use of old and/or improperlymixed fuel is the most common cause
of performance problems. Use only fresh, clean unleaded gasoline.
Follow the instructions carefully for the proper gasoline/oil mixture.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and oxygenates such as
ethanol, methanol or MTBE (ether). Alcohol-blended fuel absorbs
water. As little as 1% water in the fuel can make fuel and oil
separate, forming acids when stored. ALWAYS use fresh fuel (less
than 30 days old).
NOTE: Dispose of old fuel according to federal, state and local
regulations.
Using Blended Fuels
if using a blended fuel:
• Always use the fresh fuel mix explained in your operator's manual
Use the fuel additive STA-BIL® or an equivalent
Always agitate the fuel mix before fueling the unit
Drain the tank and run the engine dry before storing the unit
_WARNING: DO NOT USE E85 FUEL IN THIS UNIT. it |
Using Fuel Additives
The bottle of 2-cycle oil provided with this unit contains a fuel
additive to help inhibit corrosion and minimize gum deposits.
Always use the brand of 2-cycle oil that came with this unit. if this is
unavailable, use a 2-cycle oil designed for air-cooled engines and
mix it with a fuel additive, such as STA-BIL Fuel Stabilizer or an
equivalent. Add 0.8 oz. (23 mL) of fuel additive per gallon of fuel,
according to the instructions on the container. NEVER add fuel
additives directly to the unit's fuel tank.
Mixing the Fuel
NOTE: This unit comes with a 3.2 oz. (95 mL) bottle of 2-cycle oil.
has been proven that fuel containing greater than 10%
ethanol will likely damage this engine and void the warranty.
To obtain the correct fuel mixture described below, pour the
entire bottle into one gallon of unleaded gasoline.
FUELING THE UNiT
WARNING: Gasoline is extremely flammable, ignited
vapors may explode. Always stop the engine and allow it
to cool before filling the fuel tank. Do not smoke while
filling the tank. Keep sparks and open flames at a distance
from the area.
WARNING: Remove the fuel cap slowly to avoid injury
from fuel spray. Never operate the unit without the fuel cap
securely in place.

PREPARING THE WORK AREA
• Clear the area of children, bystanders and pets; keep them
outside a 50-foot (15 m) radius, at a minimum. Even then, they
are still at risk from thrown objects. Encourage bystanders to
wear eye protection. Ifyou are approached, stop the unit
immediately. When felling, the safe distance is at least twice the
height of the tallest tree in the work area. When bucking, keep
workers at least 15 feet (4.6 m) apart.
Keep the work area clean. Cluttered areas invite injuries. Do not
start cutting until the work area is clear and free from
obstructions. Make sure there is secure footing and a planned
retreat path from falling trees or branches.
Do not cut near electrical cables or power lines. Keep at least 50
feet (15 m) away from all power lines.
Use the unit only in daylight or good artificial light.

HOLDING THE UNiT
[_J ARNING-" Always hold the front handle with the left
hand and the rear handle with the right hand. Always keep
all body parts to the left of the chain line.
Firmly encircle the handles with the thumbs and fingers (Fig. 6).
This will help reduce the chance of losing control of the unit if
kickback occurs. Any grip with thumbs and fingers on the same
side of the handles is dangerous (Fig. 7).
Always grip the unit firmly with both hands when the unit is
running.
Hold the front handle with the left hand. Keep the left arm
straight to help withstand potential kickback.
Hold the rear handle with the right hand. Keep the right arm
slightly bent.
Use these hand placements whether the operator is left-handed
or right-handed. This will help keep the operator slightly to the
left of the unit and out of the direct line of the chain saw if
kickback occurs (Fig. 8 and Fig. 9).
Stand in a stable position with feet apart and firmly planted.
Do not cut above shoulder height. Do not overreach.

CUTTING PROCEDURE BASICS
1. Start the unit. Refer to Starting instructions in the Starting and
Stopping section.
2. Keep your fingers off the throttle control until you are ready to
make a cut.
3. Accelerate the unit to full speed before cutting.
4. Press the unit against the wood and maintain a firm, steady
pressure through most of the cut. Do not put pressure on the
unit at the end of the cut.
5. Maintain a steady speed throughout the cut. Keep the unit
running through the entire cut.
6. Do not try to force the saw through the wood. Allow the saw
chain to do the cutting. Exert only light pressure. Forcing the cut
could result in damage to the unit or personal injury.
7. Release the throttle control as soon as the cut is completed.
Allow the saw chain to come to a complete stop. The saw chain,
guide bar and engine may experience unnecessary wear if the
unit is run without a cutting load.

FELLING: SAFETY
Felling is the process of cutting down a tree. Follow these safety
precautions to reduce the risk of serious injury, property damage
and damage to electrical lines:
• Do not fell trees with an extreme lean. Do not fell trees with
rotten limbs, loose bark or hollow trunks. Have these trees
pushed or dragged down with heavy equipment.
Do not cut trees near buildings or electrical lines. Leave these
operations for professionals. If a felled tree does contact an
electrical line, notify the utility company immediately.
Check the tree for damaged or dead branches that could fall
and cause serious injury.
Remove dirt, stones, loose bark, nails, wire and other
obstructions from the portion of the tree that will be cut.
When bucking and felling operations are performed by two or
more persons in the same general area, they should be
separated from each other by a distance of at least twice the
height of the tree to be felled.
Consider the force and direction of the wind. Consider the lean
and balance of the tree. Consider the location of large branches.
All of these factors influence the direction that the tree will fall. Do
not try to fell a tree in a direction other than its natural fall line.
Do not fell trees during periods of precipitation or high winds.
Determine a safe and expedient escape route. Clear the area
around the tree and make sure there are no obstructions
blocking the escape route. Establish a 90° corridor of escape,
approximately 135 ° from the line of fall (Fig. 10).
Stay uphill from the tree; it will most likely roll or slide after it falls.

FELLING: PROCEDURE
Small trees, up to 6 - 7 inches (15 - 18 cm) in diameter, are usually
felled in a single cut. Larger trees require a sequence of two cutting
operations: a notched undercut followed by a felling back cut. It
may also be necessary to remove buttress roots.
Step 1: Removing Buttress Roots
Buttress roots are large roots that extend above the ground and
help support the tree. If the tree has large buttress roots that might
impede the felling process, follow these steps to remove them:
1. Make a horizonal cut into the buttress root (Fig. 11). To prevent
the guide bar from being pinched by the weight of the wood,
always make this cut first.
2. Make a vertical cut into the buttress root (Fig. 11).
3. Remove the loose section from the work area.
Step 2: Making the Notched Undercut
_ ARNING: Never walk in front of a tree with a notched
This cut determines which direction the tree will fall. Always make
this cut on the side of the tree facing the direction where the tree
should fall. Make the cut at 90° to the line of fall.

should be about 1/3 the diameter of the tree and close to the
ground. To prevent the guide bar from being pinched by the
weight of the wood, always make this cut first.
Make a 45° cut into the trunk of the tree, above the first cut (Fig.
12). Continue cutting until the two cuts meet.
Remove the loose section from the work area.

tree is going to fall in the correct direction. If there is a chance
that the tree might not fall in the desired direction, or if the tree
might rock back and bind the chain saw, remove the guide bar
from the cut, stop the unit and use wedges to open the cut and
direct the fall (Fig. 14). Only use soft plastic or wooden wedges.
Drive the wedges into the cut slowly. Once the wedges are in
place and the cut is held open, either carefully reinsert the guide
bar and continue the cut or slowly drive the wedges in further to
push the tree over.

engine and set the unit down immediately. Promptly exit the area
along the retreat path, but keep watching the tree as it falls.

DANGER: If the tree starts to fall in the wrong direction
and binds the chain saw, leave the unit and evacuate the
area immediately! Do not try to save the chain saw!
WARNING: Stay clear of spring poles when operating the
unit. Spring poles are branches, logs, roots or saplings that
are bent under tension by other wood (Fig. 15). When the
tension is released, spring poles can strike the operator,
causing serious injury and potentially knocking the chain
saw into the operator's body. Use extreme caution when
cutting spring poles or when releasing the cause of tension.
LIMBING
Limbing is the process of removing branches from a fallen tree.
1. Leave the larger support limbs under the tree for last (Fig. 16).
These will keep the tree off the ground during the limbing process.
2. Cut one limb at a time. Stand on the opposite side of the tree
from the limb (Fig. 16). Keep the trunk between the operator and
the chain saw. To avoid binding the chain saw, branches under
tension should be cut from the bottom up.
3. Remove the cut limbs from the work area.

BUCKING: SAFETY
Bucking is the process of cutting a fallen tree into logs of desired
lengths. Follow these safety precautions to reduce the risk of
serious injury:
• Clear the area of objects or obstructions that could contact the
guide bar and result in kickback.
When bucking on a slope, always stand on the uphill side of the
fallen tree.
If possible, the end of the tree to be cut should be raised off of
the ground. A saw horse is ideal for this purpose. If a saw horse
is not available, use other logs or any remaining limb stumps.
Make sure the tree if firmly supported.
Do not let the saw chain contact the ground or saw horse.
Cut one log at a time. Release the throttle control and allow the
saw chain to come to a complete stop before moving on to the
next log.
Keep feet and all other body parts clear of falling logs.
DANGER: Use extreme caution when cutting a fallen
tree that is still attached to the root structure. When the
trunk is separated from the roots, the stump has a high
potential for rocking back into the hole created by the
roots. This can result in serious injury or death. Never
stand in the hole left by the roots. Never allow others to
stand near the root structure.

BUCKING:PROCEDURE
Cutting Logs Under Stress
When logs are supported on one or both ends, the wood tends to
bend during the cutting process. This can cause the chain saw to
become pinched between the two sides. Pay extra attention.
1. Make the first cut approximately 1/3 the diameter of the log. Do
not cut deeper than 1/3.
• If the log is supported on one end (Fig. 17), make the first cut
from below (underbucking). Refer to Underbucking.
• If the log is supported on two ends (Fig. 18), make the first cut
from above (overbucking). Refer to Overbucking.
2. Make the second cut from the opposite side until the two cuts
meet. If the diameter of the wood is large enough, insert soft plastic
or wooden wedges to hold the cut open and prevent pinching (Fig.
21). Take care not to touch the wedges with the saw chain.
Cutting Fully-Supported Logs
When logs are supported along the entire length, extra care should
be taken to make sure the saw chain does not contact the ground
or other support structure (Fig. 19).
1. Cut through the log as much as possible, without cutting into the
ground or support structure. Cut from above (overbucking).
Refer to Overbucking.
2. Roll the log over and finish cutting through the log from above
(overbucking).

Fig. 20
Overbucking
1. Begin cutting from above, with the bottom of the saw chain
against the top of the log (Fig. 19).
2. Exert light, downward pressure. The saw will tend to pull away
from the operator. Be prepared and hold the saw firmly to
maintain control.
Underbucking
1. Begin cutting from below, with the top of the saw chain against
the bottom of the log (Fig. 20).
2. Exert light, upward pressure. The saw will tend to push toward the
operator. Be prepared and hold the saw firmly to maintain control.

PRUNING
WARNING: Do not cut above shoulder height. Use a
pole saw to cut limbs above shoulder height or hire a
professional. Do not operate the unit in a tree or on a
ladder unless specifically trained to do so.
WARNING: Falling branches can cause serious injury.
Always wear appropriate head protection. Plan an escape
route away from falling limbs. Do not position any body
parts directly below the limb when cutting.
Pruning is the process of cutting limbs from a living tree.
1. Make the first cut approximately 6 inches (15 cm) from the tree
trunk. Cut upward, from the underside of the limb. Use the top
of the guide bar to make this cut. Cut a third of the way through
the diameter of the limb (Fig. 22).
2. Make the second cut 2 - 4 inches (5 - 10 cm) farther out on the
limb. Cut downward, from the top of the limb. Use the bottom of
the guide bar to make this cut. Cut completely through the limb
(Fig. 22).
3. Make the third cut as close to the tree trunk as possible. Cut
upward, from the underside of the limb stub. Use the top of the
guide bar to make this cut. Cut a third of the way through the
diameter of the limb (Fig. 22).
4. Make the fourth cut directly above the third cut. Cut downward,
from the top of the limb stub. Use the bottom of the guide bar to
make this cut. Cut completely through the limb stub to meet the
third cut (Fig. 22). This will remove the limb stub.
