KICKBACK
Kickback is a dangerous reaction that can lead to serious
personal injury. Do not rely only on the safety devices
provided with your saw. As a chain saw user, you must
take special safety precautions to help keep your cuffing
jobs free from accident or injury.
REDUCETHECHANCEOF
KICKBACK

. _\KICKBACK WARNING
Kickback can occurwhen the moving chain contacts
an object at the upper portion of the tip of the guide bar
or when the wood closesin and pinches thesaw chain
in t hecut, Con tact at the upper portion of the tip of the
guide barcan 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 personal injury.

Recognize that kickback can happen. With a
basic understanding of kickback, you can reduce
the element of surprise which contributes to
accidents.
Never let the moving chain contact any object at the
tip of the guide bar. Figure 1.
Keep the working area free from obstructions
such as other trees, branches, recks, fences,
stumps, etc. Figure 2. Eliminate or avoid any
obstruction that your saw chain could hit while you
are cutting through a particular log or branch.
Keep your saw chain sharp and properly tensioned. Followmanufacturer'schain sharpeningand
maintenance instructions.Check tension at regular
intervalswiththe engine stopped,neverwiththe engine
running. Make sure the bar clamp nuts are securely
tightened after tensioning the chain. A loose or dull
chain can increase the chance of kickback to occur.
Begin and continue cutting at full throttle. If the
chain is moving at a slower speed, there is greater
chance for kickback to occur.
Cut one log at a time.
Use extreme caution when re-entering a previous
cut.
Do not attempt plunge cuts.
Watch for shifting logs or other forees that could
close a cut and pinch or fall into the chain.
Use the Reduced-Kickback Guide Bar and LowKickback Chain specified for your saw.

Keep a good firm grip on the saw with both hands
when the engine is running and don't let go.i
Figure 3. A firm grip can neutralize kickback and
help you maintain control of the saw. Keep the
fingers of your left hand encircling and your left
thumb under the front handlebar. Keep your right
hand completely around the rear handle whether
you are right handed Orleft handed. Keep your left
arm straight with the elbow locked.
2. Position your left hand on the front handlebar so it
is in a straight line with your right hand on the rear
handle when making bucking cuts. Figure3. Never
reverse right and lefthand positions.
3. Stand with your weight evenly balanced on
both feet.
4. Stand slightly to the left side of the saw, to keep
your body from being in a direct line with the
• cutting chain. Figure 3.
5. Do not overreach. You could be drawn or thrown
off balance and lose control of the saw.
6. Do not cut above shoulder height. It is difficult to
maintain control of the saw above shoulder height.

as non-fogging, vented g0ggles or face screen; an approvedsafety hard hat, and sound barders -- ear plugsor
mufflers to protect your hearing. Regular users should
have hearing checked regularly as chain saw noise can
damage hearing.
Keep children, bystanders, and pets Out of the work
area -- a minimum of 30 feet (10 meters). Do not allow
other people or animals to be near the chain saw when
starting or operating the chain saw.
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

SAW SAFELY
Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely
assembled.
Operate the chain saw only in outdoor areas.
Do not operate the saw from a ladder or in a tree.
Position all parts of your body to the leff of cut and
away from the saw chain when the engine is
running.
Cut wood only. Do not use your saw to pry or shove
away limbs, roots or other objects.
Make sure the chain will not make contact with any object while starting the engine. Never tryto startthe saw
when the guide bar is in a cutor kerf.
Use extreme caution when cutting small size brush
and saplings. Slender material can catch the saw
chain and be whipped toward you or pull you off
balance.
Be alert for springback when cutting a limb that is
under tension so you will not be struck by the limb or
saw when the tension in the wood fibers is released.
Do not put pressure on the saw at the end of a cut.
This can cause you to lose control when the cut is
completed.
Stop the engine before setting the saw down.
MAINTAIN
WORKING
1.
YOUR
YOUR SAW IN GOOD
ORDER
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
flywheel to burst.
Keep fuel and oil caps, screws and fasteners
securely tightened.
Keep the handles dry, clean, and free of oil or fuel
mixture.
Make certain the saw chain stops moving when the
throttle trigger is released. For correction, refer to
page 20 for carburetor idle adjustment instructions.
Stop the saw if the chain strikes a foreign object. Inspect the unit and repair or replace parts as necessary.
Disconnect the spark plug before performing any
maintenance except for carburetor adjustments.
CARRY
AND
STORE
YOUR
SAW SAFELY
1.
Hand carry the unit with the engine stopped, the
muffler away from your body, and the guide bar and
chaintothe rear covered preferablywith a scabbard.
2.
Before transporting in any vehicle or storing in any
enclosure, allow your saw to cool completely, cover
the bar and chain and properly secure to avoid
turnover, fuel spillage or damage.
3.
Drain oil and fuel tank before storing for more than
30 days.
4.
Store in a dry area out of reach of children and away
from where fuel vapors can reach sparks or an open
flame from hotwater heaters,furnaces, etc.
NOTE: Exposure to vibrations through prolonged use of
chain saws may produce Whitefinger disease
(Raynaud's phenomenon). This phenomenon
reduces the hand's ability to feel and regulate
temperature, produces numbness and burning
sensations and can cause nerve and circulation
damage and tissue necrosis.
An anti-vibration system designed to reduce
engine vibration is recommended for those using
chain saws on a regular or sustained basis. An antivibration system does not guarantee the
avoidance of Whitefinger disease. Continual and
regular users must monitor closely their use of
chain saws and physical condition.
Notice: Refer to the Code of Federal Regulations, Section
1910.266(5); 2.5.1 of American National Standard
Safety Requirements for Pulpwood Logging, ANSI
03.1-1978; and relevant state safety codes when
using a chain saw for logging purposes.
SAVE THESE INSTRUCTIONS
Never modify your saw in any way. Use only attachments supplied or specifically recommended by the
manufacturer.
Always replace the handguard immediately if it
becomes damaged, or broken or is otherwise
removed.

MIXTURE
• Your chain saw is powered by a two-cycle engine
which requires a fuel mixture of regular,
unleaded gasoline and a high quality engine oil
specially made for 2-cycle, air-cooled engines.
The internaldesign of the 2-cycle engine requires
lubrication of moving parts. Lubrication is provided
when you usethe recommended mixtureof gasoline
and oil.
Gasoline must be clean and not over two
months old. After a short period of time,
gasoline begins to chemically break down
and will form compounds that can cause hard
starting and damage in 2-cycle engines.
• The correct measure of gasoline to oil is very
important.
--Too much oil in the mixture will foul the
spark plug.
--Too little oil will cause the engine to overheat resulting in damage.
• Mix the fuel thoroughly in a container since
gasoline and oil do not readily combine. Do not
try to mix fuel directly in the fuel tank.
1. USETHE
FOLLOWING
FUEL MIXTURES:
2. DO NOT USE:
• BIA Oil (Boating Institute of America)
--Does
not have proper additives for aircooled, 2-cycle engines and could cause
damage.
• AUTOMOTIVE
OIL- Does not have proper additives for 2-cycle
engines and could cause damage.
• GASOLINE
CONTAINING
ALCOHOL-
(High Test, Premium or Gasohol)
-- Stiffens critical carburetor fuel metering elements and causes engine damage from
overheating.
-- Increases vapodock (causes hard starting).
-- Attracts water causing corrosion damage.

BAR
•
AND
CHAIN
OIL
The guide bar and cutting chain require continuous lubrication in order to remain in
operating 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.
• Use Sears Bar and Chain Lubricant #71-36554
or clean SAE 30W oil.
• In freezing weather oil will thicken, making it
necessary to thin bar and chain oil with a
sm_ill amount of Diesel Fue! #1 or Kerosene.
Bar and chain oil must be free flowing for the
oil system to pump enough oil for adequate
lubrication.
FILL THE OIL
TANK EACH
THE FUEL TANK
IS FILLED.
1. USE THE
FOLLOWING:
3O°F or above -- Lubricant -- undiluted.
30°F - O°F --
95% lubricant to 5% Diesel
Fuel #1 or Kerosene.
Below 0°F --
90% lubricant to 10%
Diesel Fuel #1 or Kerosene.
2. HOW TO FILL THE OIL TANK
a. Stop the engine.
b. Turn saw on its side with oil cap up. Figure
17.
c. Loosen cap slowly and wait for pressure in
the tank to be released before removing the
cap.
d. Fill the oil tank.
e. Replace the oil cap securely.
3. IMPORTANT
POINTS
TO REMEMBER
a. Fill the oil tank each time you refill the fuel
tank to ensure there will be sufficient oil for
the chain whenever you start and run the
saw.
Figure 17
10
b. The saw will use about 1/2 tank of chain oil
for each tank of fuel mixture. If less oil is
used, check for a plugged oil hole in the
guide bar.
c. It is normal for a small amount of oil to appear under the saw after the engine stops.
This is due to oil draining from the bar and
chain when not in use.

TYPES
A.
BASIC
OF CUTTING
CUTTING
TECHNIQUE
1. IMPORTANT POINTS.
a. Cut wood only. Do not cut metal, plastics,
masonry, non-wood, building materiels; etc.
b. Stop the saw if the chain strikes a foreign
object. Inspect the unit and repair or replace
parts as necessary.
c. Keep the chain out of dirt and sand. Even a
small amount of dirt will quickly dull a chain and
thus, increase the possibility of kickback.
L_. KICKBACK WARNING
Kickback can occur when the moving chain contacts an
object at the upper portion of the tip of the guide bar or
Whenthe 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
f_S_,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 personal injury.
2. UNDERSTAND
REACTIVE FORCES
Pinch-Kickback and Pun-In occur when the chain
is suddenly stopped by being pinched, caught, or
by contacting a foreign object in the wood. This
results in a reversal of the chain force used to cutwood
and causes the saw to move in the opposite direction of
chain rotation. Either reaction can result in lose of control and possibleserious personal injury.
• Pinch-Kickback
---occurs when the chain, on top of the bar is suddenly
stopped when the top of the bar is used for cutting.
--rapidly drives the saw straight back toward the
operator.
• Pull-In-- can occur when the chain on the bottom of the
bar is suddenly stopped.
--pul/s the saw rapid/yforward,

FELLING
PROCEDURE
Practicecuttinga few small logsusingthefollowing techn_
que to getthe 'feel" of usingyoursaw beforeyou begin
major sawing operation.
a. Accelerate the engine to full throttle just before
entering the cut by squeezing the throttletrigger.
b. Begin cutting with the spur against the log.
Figure 20.
c. Keep the engine at full threttle the enUre time you
are cutting.
d. Allow the chain to cut for you; exert only light
downward pressure. If you force the cut, damage to
the bar,chain, or engine can result.
e.
Release the throttle trigger as soon as the cut is
completed, allowing the engine to idle. If you runthe
saw at full throttlewithout a cuttingload, unnecessary
wear can occur to the chain, bar, and engine.
f. Do not put pressure on thesawat theend ofthecut
to avoid losing control when the cut is complete.
g. Stop the engine before setting the saw down after
cutting.

TECHNIQUES
1. PLAN YOUR SAWING OPERATION
CAREFULLY IN ADVANCE
e. Clear the work area. You need a clear area all
around the tree where you can have secure
footing.
b. Study the naturel conditions that can cause
the tree to fall in a particular direction:
1.) TheWlNDdiroctionandspeed
2.) The LEAN of the tree
3.) WEIGHTED with BRANCHES on one side
4.) Surrounding'TREES and OBSTACLES
c. Look for decay and rot, If the trunk is rotted,
it could snap and fall toward the operator.
12
3.
d. Check for broken or dead branches which
could fall on you while cutting.
e. Make sure there is enough room for the tree
to fall. Maintaining a distance of 21/2 tree
lengths from the nearest person or other objects. Engine noise may drown out warning
call.
f. Remove dirt, stones, loose bark, nails,
staples, and wire from the tree where cuts
are to be made.
g. Plan to stand on the up-hill side when cutting on a slope.
h. Plan a clear retreat path to the rear and
diagonal to the line of fall. Figure21.
2. FELLING SMALL TREES -- LESS THAN
6" IN DIAMETER
a. Ifyou know the direcUon of fall:
1.) Make a single felling cut on the side away
from the direction of fall.
2.) Cut all the way threugh.
3.) Stop the saw, put it down, and get away
quickly 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.

z_WARNING
DO NOT CUT:
-- near electrical wires or buildings.
-- if you do not know the direction of tree fall.
-- at _ ight since you will not be able to see well.
--during
bad weather-- strong wind, snow, rain,
etc.
3. FELLING LARGE TREES'-6" DIAMETER
OR MORE
The notch method is used to cut large trees. A
notch is cut on the side of the tree in the desired
direction of fall. After a felling cut is made on the
opposite side of the tree, the tree will tend to fall
into the notch.
.i --iZ
Figure23
1
NOTE: Before the felling cut is complete, drive
wedgestoopen upthecutwhen necessarytocontrolthedirecf_onoffall. Use woad or plasticwedges
but never metal, to avoid kickback and chain
damage.
e. Be alert for signs that the tree is ready to fall:
t.) crackingsounds
2.) widening of the felling cut
3.) movement in the upper branches,
f. As the tree starts te fall, stop the saw; put it
down, and get away quickly on your planned
retreat path.
g. Be extremely cautious with partially fallen trees
that may be poorly supported. When a tree
doesn't fall completely, set thQ saw aside and
pull down the tree with a cable winch, block and
tackle or tractor. Do not cutitdown with your saw
to avoid injury.
c. Leave enough uncut wood between the felling
Cutand the notch to form a hinge. Figure 24.
NOTE: The hinge helps to keep the tree from
twisting and falling in the wrong direction.
d. Use a wedge if there is any chance that the tree
will not fall in the desired direction.
Check the wind
Don't cut down wind.
Figure24
_WARNING
Stay on the uphill side of the terrain to avoid the
tree rolling or sliding downhill after it is felled.
a. Make the notchcut. Figure 23.
f.) Cut the bottom of the notch first, through
1/3 of the diameter of the tree.
2.) Complete the notch by making the slant
cut.
3,) Remove the notch of wood.
b. Make the felling cut on the opposite side of the
notch about 2" higher than the bottom of the
notch.
PUT YOURSELF

to the desired log size.
1. IMPORTANT
1ST CUT
PRESSURESIDE _
4-'--
POINTS
a. Cut only one log at a time.
b. Cut shattered wood very carefully. Sharp
pieces of wood could be flung toward the
operator.
c. 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.
d. 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. (Figure 25)
e. Do not cut in an area where logs, limbs and
roots are tangled such as in a blown down
area. Drag the logsinto a clear area before cutting by pulling out exposed and cleared logs
first,
f. 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 the log is being cut, 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.

• Work slowly, keeping both hands on the saw
with a firm grip. Maintain secure footing and balance.
• Watch out for springpoles. Use extreme caution
when cutting small size limbs. Slender material
may catch the saw chain and be whipped toward
you or pull you off balance.
• Be alert for springback. Watch out for branches
that are bent or under pressure as you are cutting
to avoid being struck by the branch or the saw when
the tension in the wood fibers is released.
• Keep a clear work area. Frequently clear branches out of the way to avoid tripping over them.

2. PRUNING
a. Limit pruning to limbs shoulder height or
below. Do not cut if branches are higher than
your shoulder. Get a professional to do the
job.
b. Refer to Figure 31 for the pruning technique.
1.) Undercut 1/3 of the way through the limb
near the trunk of the tree.
2.) Finish with an overcut farther out from the
trunk,
3.) Keep out of the way of the falling limb,
4,) Cut the stump flush near the trunk of the
tree.
_WARNING
Be alert for and guard against kickback. Do not allow
the moving chain to contact any other branches or
objects at the nose of the guide bar when debranching
or pruning. Allowing such contact can result in serious
personal injury.
1. DEBRANCHING
a. Always debranch a tree after it is Cut down, Only thencan debranching be done safely
and properly.
b. Leave the larger lower limbs to support the
tree as you work.
c. Start at the base of the felled tree and work
towards the top, cutting branches
and
limbs. Remove small limbs with one cut. Figure 30,
d. Keep the tree between you and the chain.
Cut from the side of the tree opposite the
branch you are cutting.
e. Remove larger, supporting branches with
the 1/3, 2/3 cutting techniques described in
the bucking section.
1.) Start with an overcut
2.) Finish with an 5vercut
f. Always use an overcut to cut small and
freely hanging limbs, Undercutting could
cause limbs to fall and pinch the saw.

• Clutch maintenance is required when:
--the chain continues to turn while engine
idles after the idle speed screw has been
adjusted to its capacity.
--slippage occurs during a cut.
--a chattering noise occurs during cutting.
• Clean the clutch, drum/sprocket
and surrounding area daily during heavy use of the
saw. Check to see that the clutch drum turns
freely and smoothly.
• Inspect the drum/sprocket regularly for wear.
A worn sprocket will make the chain run erratically
and will shorten the life of the bar and chain. Figure 47.

COUNTER.VIBE
® ANTI-VIBRATION
SYSTEM
This saw is equipped with a counter vibration
system consisting of 5 isolator mounts. Figure
53. The Isolator Mounts protect the user from
engine, bar, and chain vibration similar to the
way shock absorbers on a car protect from jolts
and bumps in the road.
1. Check isolators each time the saw is used.
2. Replace isolators when:
--vibration increases
--mounts
develop an out of round or
swollen
shape usually
caused
from
exposure to gasoline
and oil for long
,periods of time,
3. Replace all five isolators when a failure to one
occurs.
