El
INTRODUCTION :.....
The_information found in this manual.will help
you properly prepare your chain saw -for use,
understand how to operate your saw safely, and
perform maintenance required to keep your unit
in top working condition.
Your saw has been designed with safety in mind
and includes the following safety features, as
standard equipment:
Handguard
Lo Kick Guide Bar
Guard Link Chain
The chain saw should never be operated unless
these devices are properly installed on the unit.
The Lo Kick Guide Bar and Guard Link Chain

of KICKBACK. You should thoroughly read and
_understand the section, "CONTROLLING
KICKBACK" on page 11 before operating the
saw.
STATE AND LOCAL ORDINANCE
REQUIREMENTS
_Your Saw has; been; furnished with an'approved
Spark AFestorScreen which is required in some
areas bylaw. You are legally responsible for see-
ing that the Spark Arrestor is properly main-
tained in these areas. Failure to do so could sub-
ject you to liability or to a fine. See Spark Ar-
restor maintenance, page 19.
Check with your state conservation or forestry
department about regulations concerning oper-
ating your saw on forest, brush, or grass covered
areas. All U.S. forest land and the states of
California, Maine, Washington and Oregon re-
quire many internal combustion engines to be
equipped with a temperature limiting muffler by
law. Such laws require fitting your saw with an
additional muffler heat shield.

D. CHAIN TENSION
• Chain tension is very important:.
--a loose chain wi!t wear the bar and itself.
--a loose chain can jump off the bar while
you are cutting.
--a tight chain can damage the saw and/or
break.
--a:chain, either too loose or too tight, can
cause injury.
• Chain tension is correct when thechain:
:_can be lifted aboutll8'_ from the Guide Bar
at a point near the middle of_the bar, and
•_--will move freely around the bar.
• The chain stretches during use, especially

E. ENGINE FUEL MIXTURE
• Ydur chain saw is powered by a two-cycle
engine?-Which requires a fuel mixture of
regula_gasoline, leaded or unleaded,'and a
high ,quality engine, oil- specially made- for
2-cycle, air-cooled engines. The internal
design of the 2-cycle engine requires lubrica-
tion of moving parts. Lubrication is provided
when you use the recommended mixture of
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 wil! form compounds that can cause hard
starting and damage in 2-cycle engines.
•The correct measure of gasoline to oil is very
importanL
--Too much oil in the mixture will foul the
spark plug.
--Too little oil will cause the engine to over-
heat and freeze up.
• Mix the ,fuel thoroughly in a separate con-
tainer since gasoline and oil do not readily
combine,

c. Fill the oil tank,
d. Replace the oil cap securely,
BAR AND CHAIN OIL
• The guide bar and cutting chain require con-
stant 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 andJor
,discoloration of the guide bar rails.
eUse SEARS Bar and Chain Lubricant #36554
or clean SAE 3OW oil,
3. IMPORTANT POINTS
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 Fun the

C. CONTROLLING KICKBACK
Kickback is a dangerous chain saw reaction that
can cause serious personal injury. Carefully
study this section before you make the first cut
with your new saw, You must understand what
causes kickback, how you can reduce the
chance of kickback, and how you can remain in
the best control of the saw if kickback does oc-
cur.
'1.:WHAT CAUSES KICKBACK
"V::_tKickback can happen when the moving chain
contacts an object at the tip of the guide bar.
•This contact causes the chain to dig.into the
_ _bject and stops the chain for an instant. The
result is a lightning fast, reverse reaction
which kicks the saw tip up and back at the
: operator. The operator can lose control of the
•saw and the cutting chain can cause serious
.,,,.injury if it contacts any part of the body.

2. HOW YOU CAN REDUCE THE CHANCE
OF KICKBACK
a. Recognize that Kickback can happen, By
understanding and knowing about kick-
back, you can help eliminate the element of
surprise.
b. Avoid letting the moving chain contact any
object at the tip of the guide bar, F!gure 20.
c. Keep the working area free from:obstruc.
tions such as branches, rocks;, fences,
stumps, etc, Figure 21. Eliminate,.or avoid
any obstruction that the chaHi,:could hit
while cutting through aparticdlar log or
branch.
d. Keep your saw" chain sharp and properly
tensioned. Aloose or dull chain can in-
crease the chance of kickback. ::
e_Operate2the .engine at full thro_{le for all
......cuttirlg; If the Chain is moving _'÷a slower
speed during cutting, there i_s;greater
chance for kickback to occur.
[ Use the Lo Kick Guide Bar and Guard Link
Chain designed {or your particular saw.
These devices have been designed to
reduce the posibility of kickback.
g. Use extra caution if your saw is equipped
with the Power Sharp System, The Power
Sharp saw is equipped with aLo Kick
Guide Bar and a Guard Link Chain.
However, due to the chain requirements of
the built in sharpening mechanism,
kickback force from the Power Sharp chain
may be greater than that from otherGuard
Link chains.
3. HOW YOU CAN MAINTAIN THE BEST
CONTROL
a. Keep a good firm grip on the saw._with both
hands. F!gure 22. A firm grip:';_-an he!p
neutralize kickback, tKeep the :_i_ige'r's of"
your qefthand-'encircling and your left
thumb under the: front handteb:ar. Keep
your right hand completely around the rear
handle. Keep your left arm straightwith the
elbow locked.
b. Position your left hand on .the front
handlebar so it is in a straight line,with your
right hand on the rear handle. Figure 22.
Never reverse right and left hand positions
on the saw handles.
c. Stand with your weight evenly balanced on
both feet.
d. Stand slightly to the left side of the saw, to
keep your body from being in a direct line
with the cutting chain, Figure 22.
e. Do not over reach. You could be drawn off
balance and lose control of the saw.
f, Do not cut above shoulder height. It is dif-
ficult to maintain control of the saw if you
cut above shoulder height. 11

USING THE POWER SHARP SYSTEM [MODEL .3536901
12
Model .353690 is equipped with aPower Sharp
System that will perform approximately 80% of
the sharpening necessary for the saw chain. The
Power Sharp System utilizes a built-in grinding
stone to sharpen the cutter top plates,and set
depth gauges. As the built-in sharpener is used,
the cutter side plates gradually will be altered,
About every 3rd to 5th time the Power Sharp
System is used, hand filing is required to correct
the c_btter side plates.
• Sharpen the saw chain when:
--wood chips become small and powdery.
Wood chips made by the chain should be
about the size of the teeth of the chain.
--saw_e_uts to one side.
--saw has to be forced through the cut.
......A: AUTOMATICSH ARPENING .............................
Replace the sharpening stone when a new
Power Sharp chain is installed. See instruc-
tions, page 13.
Remove the sharpening stone if a standard or
conventional chain is substituted for the
Power Sharp chain. See instructions for
removing the sharpening Stone and Carrier
Assembly, page 13. Use replacement chain
for Model 358..353670 (2_31t6")_ StoCk, No.
36-3629. Follow conventional chain sharpen-
ing instructions on page 17.
ICAUTiON:IAIways wear gloves when handling
the chain. Thechaincan cut you even though
it is too dull to cut wood.
1. Stop the engine.
2. Place saw on a solid, flat surface; and ensure
that the chain will not contact any object.
3. Adjust the chain with proper tension. Refer to
Chain Tension, page 7.
4. Start engine and operate at ha!f throttle.
5. Press the Power Sharp Knob down until you
feel the sharpening stone lightly contacting
the chain. Figure 23.
6. Maintain constant, tight pressure on the
Power Sharp Knob while 'moving the knob
side to side for 5 seconds.
7. Release Power Sharp knob and stop engine.
8. Inspect chain cutters.
NOTE: A properly sharpened cutter will sflow
grinding marks across its entire width. Figure

Figure 29
Practice cutting afew small logs using the
following technique to get the "feel" of using
your saw before,you begin a major sawing
operation. " ' . . .
a.,Accelerate-the .engine to fu!!: throttle just
before entering the cut.
b. Begin cutting with the bottom of the saw
frame against the log. Figure 29.
c. Keep the engine at full throttie:.the entire time
you are cutting. ......
d. Allow the chain to cut for you; eXerf only light
downward pressure, if you force the cut,
damage to the bar, chain, or engine can
result.
e. Release the trigger as soon as the cut is com-
pleted, allowing the engine to idle. If you run
the saw at full throttle without a cutting load,
unnecessary wear will occur to the chain, bar,
and engine.
f. Stop the engine before setting the saw down
after cutting. .13

Bn TREE FELLING TECHNIQUES
1. PLAN YOUR SAWING OPERATION CARE-
FULLY IN ADVANCE
a. Clear the work area. You need a clear area
all around the tree where you. can have
secure footing.
b. Study the natural conditions that can
cause the tree to fall in a particular direc.
lion. The tree wilt be likely to fall:
1.) In the direction the WIND is blowing
2.) towards the direction of the• LEAN of
the tree
.3-) on the side that is the HEAVIEST with
branches.
coMake sure there is enough room for the
free to fall.
d. Remove dirt, stones, loose bark, nails,
staples_ and wire from the tree where cuts
are to be made.
e.Plan aclear retreat path to the rear and
diagQnat_to the line of fall. Figure 30.
WARNING!
DO NOT CUT •
--near electdcal wires or buildings.
--if you do not know the direction of tree fall.
--at night since you will not be able to see well.
--during bad weather--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.
a. Make the notch cut. Figure 31.
1.) Cut the bottom of the notch first, about
1!3 of the diameter of the tree.
2.) Complete the notch by making the
slant cut.
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.
c. Leave enough uncut wood between the fell-
.!rig cut and the n0tch•.to _form a hinge.
Figure 32. •....
NOTE: The hinge helPS to keep the tree
from twisting and falling in the wrong direc-
tion.
d. Use awedge if there is any chance that the
tree will not fall in the desired direction.
2. FELLING SMALL TREES--LESS THAN 6"
DIAMETER
.a. If you know the direction of fall:
1.) Make a single felling cut on the side
away from the direction of fall.
2.) Cut all the way through.
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.

C. BUCKING
•Bucking is the term used for cutting a fallen
tree to the desired log size.
• Two types of cutting are used (Figure 33):
nOvercutting -- begin on the top side of the
log with the bottom of the saw against the
log; exert,light pressure downward.
--Undercutting-- begin on the underside of
the log with the top of the saw against the
log; exert light pressure upward. During
undercutting, the saw will tend to push
.back at you. Be prepared for this reaction
and hold the saw firmly to maintain con-
tmL
WARNING!
Never>turn the saw upside down to undercut.
The sawcannot be controlled in this position.
• M_ke'-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
:witl tend to bend. The saw can become pinch-
ed or hung inthe log if you make the first cut
deeper.
WARNING!
if saw becomes pinched or hung in a log, don't
try to force it out. You could lose control of the
saw resulting in serious personal injury and/or
damage to the saw. Stop the saw and drive a
wedge into the cut until saw can be removed
easily. Be;careful not to damage the chain with
the wedge. Figure 34.

D. DEBRANCHING AND PRUNING
•Work slowly, keeping both hands on the saw
with a firm gdp. Maintain secure footing and
balance.
• Watch out for spdngpoles, Use extreme cau-
tion when cutting small size limbs. Slender
material may catch the saw chain and be
whipped toward you or pull 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 ou tof the way to avoid tripping over
tl_em.
WARNING!
Never climb into a tree to debranch or prune. Do
not stand on ladders, platforms, or in any posi-
tion which might cause you to loose control of
the saw.
1. DEBRANCHING
a. Limit debranching to limbs shoulder height
or below. Always debranch a tree after it is
cut down, Only then can 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;
_'d. Keep the_tree between-you and'th_ Chain.
Cut •from the side of the tree opposite the
branch you are cutting.
e. Remove larger, _upporting branches with
the 1/3, 2/3 cuttihg technique described in
the bucking section.
1.) Start with an overcut
2.) Finish with an undercut

WARNING!
BE ALERT FOR AND GUARD AGAINT KICK.
BACK. Do not allow the moving chain to contact
any other branches or objects at the nose of the
guide bar when debranching or pruning. Allow.
ing such contact could result in serious per-
sonal injury.
USE COMMON SENSE KEEP THE TREE BETWEEN
YOU AND THE SAW
2. PRUNING
a. Limit pruning to limbs shoulder height or
below. Do not cut if branches are higher
than your shoulder. Get aprofessional to
do the job.
b. Refer to Figure 38 for the pruning techni-
que.
1.) Undercut 1/3 of the waY through the
.limb nearthe trunk of the.tree.
•2.)Finish with an overcut farther out f_om,
the trunk,
3.) Keep out of the way of the falling limb.
4.) Cut the stump flush near the trunk of
the tree.

MAINTENANCE
Ae
A good maintenance program: of regular inspec-
tion and care will increase the service life and
help to maintain the safety and performance of
your saw.
• Make all adjustments or repairs (except car-
buretor adjustments) with:
'",--spark plugwire disconnected
•_#ngine, cool as opposed to a unit that has
just been run. t• Check the saw for loose bolts, screws, nuts
and fittings regularly. Loose fasteners can
cause an unsafe condition as well asdamage
to your saw.
