SAFETY
RULES AND PRECAUTIONS
WARNING!
Because a chain saw is a high-speed wood-cutting tool, special safety precautions
must be observed to reduce the risk of personal accidents. Careless or improper use
may cause serious injury,
A.
KNOWYOUR
To reduce the hazard of kickback:
SAW
1. Hold the saw firmly with both hands. Left hand
on front handle bar, right hand on rear handle
whether you are right-handed or/eft-handed.
Never use the saw withone hand.
2. Do not overreach.
3. Do not let the tip of the guide bar contact the
ground, another log, branch, or any other
obstruction.
4. Begin and continuecutting atfuilthrottle.
5. Cut one log at a time.
6. Use extreme-caution when re, entering a previouscut.
7 Do not attempt plunge cuts.
8. Watch for shifting logs or other forces that
could close a cut and pinch the chain.
9. Do not out above shoulder heighL
10. Follow manufacturer's
chain sharpening
and maintenance
instructions.
Keep the
chain properlytensioned. Check tension at regular intervals with the engine stopped; never
with the,engine running. Make surethe bar
clamp nuts are securely tightened aiter tensioning the chain.
11. Use the Guard Link Chain and Lo-Kick ®
Guide Bar designed for your saw to reduce the
hazard of kickback.
Read your Operator's Manual carefully until
you completely understand and can follow all
safety.rules and operating instructions before
attempting to operatethe unit.
2. Restrictthe
use,of your saw to adult users
who understand and follow the safety rules,
precautions,
and operating
instructions
found in this manual.

GUARD
AGAINST
KICKBACK
: _
_
Kickback can lead to dangerous loss of control of
the saw and possibly cause serious personal injury. Kickback is the upward and backward motion of
the guide bar that occurswhen the moving chain contects an object at the tip ofthe guide bar.
FORCES
Pushback and Pull-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 cut
wood andcauses the-saw to move inthe opposite direction of chain rotation,'resuiting-in loss of control
and possiblesenous personal injury.

°
REACTIVE
Be extremely aware of situations or obstructions that may cause material.to pinch the top of..
orotherwisestopthechain.
,
:
.
Do not cut more than one log at a time. ......
Do not twist the saw as the baris withdrawn
from an under-cutwhenbucking. ,
• To avoid PulHn:
_
1."Always begin cutting with the engine at full
throttle and the saw housing against the
wood.
2. Use wedges made of plastic, wood, or light
alloy (never of steel or iron) to hold the cut open.

"
E.
HANDLE
FUELWITH
CAUTION
'G.
1. Eliminate all sources of sparks or flame in the
areas where fuel is mixed, poured, or stored.
There should be no smoking, open flames, or work
that could cause sparks.
2. Mix, pour and store fuel in a well-ventilated
area, on bare ground, and in an approved,
marked container.
3. Wipe up all spilled fuel before starting your
SaW.
OPERATE
YOUR
SAW SAFELY
1. Do not operate a chain saw that is damaged,
improperly
adjusted, or not completely and
securely assembled.
2. Do not operate the saw from a ladder or in a
tree.
3. Position all parts ofyour body away to the side
of the saw chainr protrudingto the left of cut when
the engine is running.
4. Cut wood only. Do not use to pryor shove away
limbs, roots or other objects.
S_ Make sure the chain will not make contact before starting the engine. Never try to start the
saw when the guide bar isin a cut or kerr.
6. Use extreme caution when cutting small size
brush and saplings. Slender matedai may catch
the saw chain and be whipped toward youor pull
you off balance.
7. 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 inthe wood fibers is
released.
8. Do not put pressure on the saw at the end of
a cut. This could cause you to lose control when
the cutis completed.
9. Stopthe engine before setUng the saw down.
MAINTAIN
WORKING
YOUR
ORDER
SAW
IN
GOOD
1. Have all chain saw service performed by your
authorized service dealer center, other than the
items listed in the maintenance section of this
manual.
2. Keep fuel and oil caps, screws and fasteners
securelytightened.
3. Keep the handles dry, clean, and free of oil or
fuel mixture.
4. Make certain the saw chain stops moving
when the throttle trigger is released, if it does
not, refer to page 21 for correct carburetoridle adjustment instructions.
5. Stop the saw if the chain strikes a foreign ob -=
ject. Inspect the unit and repair or reptace parts as
necessary.
"
6. Disconnect the spark plug before performing
any maintenance except for carburetor adjustments.
7. Never modify your saw in any way. Use only attachments supplied or specifically recommended
by Sears.
4. Move at least 10 feet (3 meters) away from fuel
and fueling site before startingthe engine.
5. Do not smoke while handling fuel or while
operating the saw.
6. Turn the engine off and let your saw cool before removing the fuel tank cap and refueling
the unit.
7. Let the saw cool in a non-combustible area, not
on dry leaves, straw ,paper, etc.
F.
r
H.
CARRY
SAFELY
AND
STORE
YOUR
SAW
1. Hand carry the unit with the engine stopped,
the Muffler away.from your body, and the Guide
Bar and Chain to the rear covered preferably with
a scabard.
2. Before transporting in any vehicle orstodng in
any enclosure, allow your saw to cool compistely, cover the bar and chain and properly secure to avoid turnover, fuel spillage or damage.
3. Drain oiland fuel tank before storing for more ._
than 30 days.
4. Store in a dry area out of the reach of children
and away from where fuel vapors can reach an
open flame from hotwater heaters, furnaces, etc.
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 may cause nerve and circulation damage and tissue necrosis. An
anti-vibration system designed to reduce engine vibration is available on many Sears models and is
recommended for those using chain saws on a regular or sustained basis.
An anti-vibration system does not guarantee the avoidance of Whitefinger disease. Continual and regular
_ usersshould monitor closely their use of chain saws and physical condition.

b. Loosen cap slowly; wait for pressure in the
tank to be released before removing the
cap.
c. Fill the oil tank.
d. Replace the oil cap securely.
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 run the
saw.

CONTROLLING
KICKBACK
Kickback is a dangerous reaction that can cause
serious personal injury. Carefully =udy this manual 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 occur.
1. WHAT CAUSES
KICKBACK
Kickback can occur when the moving chain
contacts an object at the tip or nose of-the
guide'bar. This contact causes the chain to dig
into the object and stops the chain for an instant.
The result is a lightning fast, reverse reaction
which kicks the saw tip up and back toward the
operator. The operato r can lose control ofthe saw
and the.cutting chain can cause sedous personal
injurY:if,itcontacts any part ofthe body.

2. REDUCETHE
CHANCE OF
KICKBACK
a. Recognize that kickback can happen. By
understanding and knowing about kickback,
you are better equipped to deal with an occurrence,
b. Never let the movingchain contact any objectat the tip of the guide bar. Figure 15
c. Keep the working area free from obstructions such as other trees, branches, rocks,
fences, stumps, etc. Figure 16. Eliminate or
avoid any obstruction that your saw chain
- could hit while you are cutting through a particular log or branch.
d. Keep your saw chain sharp and properly
tensioned. A loose or dull chain can increase
the chance of kickback.
.
,_
e. Begin and continue cutting at fult throttle.
"
if the chain is moving ata slower speed, there : •
is greater chance for kickback tOoccur.
'
.f. Cut one log at a time.
g. Use extreme.caution when re-entering a
previous cut.
"
h. Do notattemptplunge cuts.
i. Watch for shifting logs or other forces that
could close a cut and pinch or fall into the
chain.
j. Use the Lo-Kick_Guide Bar and Guard Link.
Chain specified for your particular saw.
'
These devices have been designed to reduce
the hazard of kickback.
k. Use extra caution if your saw is-equipped
with the Power Sharp'-" System. The Power
SharP_ saw is equipped with a_I'D-Kick" Guide
Bar and a Guard Link Chain. However, due to
the chain requirements of the built-in sharpen- .
ing mechanism, the kickback force from the .
Power Sharp-" chain may be greater than that
from other Guard Link chains.

THE BESTCONTROL
USING
THE POWER SHARP®SYSTEM
Model 358.355070 is equipped with a Power 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 fiting isrequired to correct the cutter 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 cuts to one side.
--saw has to be forced through the cuL
A.
AUTOMATIC
HAND
• Replace the sharpening stone when a new
Power Sharpe chain is installed. See instructions, page 13.
• Remove the sharpening stone if a standard or
conventional
chain is substituted for the
Power Sharp® chain. See instructionsfor removing the sharpening Stone and Carder Assembly,
page 13. Use replacement chain for Model
358.355060 (2.3/16"), Stock No. 71-3629. Follow
conventional chain sharpening instructions on
page 17.
ICAUTION:]Aiways wear gloves when handling
the chain. The chain can cut you even though
it is too dull to cut wood.
SHARPENING
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 half throttle.
5. Press the Power Sharp® Knob down until
you feel the sharpening stone lightly contacting the chain: Figure 18.
6. Maintain constant; light 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 show
grinding marks across its entire width. Figure

OF CUTTING
CUTTING
TECHNIQUE
IMPORTANT POINTS.
a. Cut wood only. Do not cut metal, plastics,
masonry, non-wood, building materials; etc.
b. Stop the saw if the chain strikes a foreign
object- Inspect theunit and repair or replace
parts as necessary.
c. Keep the chain out of dirt andsand. Even a
small amountof dirtwill quickly dull a chain and
thus, increase the possibilityof kickback.
2. UNDERSTAND
REACTIVE FORCES
Pushback and Pull-in occur when thechain 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 cut wood and causes the saw to move in theLOppositeclir_on of chain rotation, resulting in loss
ofcontrol and possible serious personal injury,
• Pushback:
--occurs when the chain, on top ofthe bar, is suddenly stopped when the top of the bar isused for
cuffing.
drives the saw straight back toward the operator,
possibly causing loss of saw control
• To avoid Pushback:
a. Be extremely aware of situations or obstructions that may cause material to stop or
pinch the top ofthe chain.
b. Do not cut more than one log atatime.
c. Do not twist the saw asthebariswithdrawn
from an under-cut.
Pull-in:
-- occurs when the chain on the bottom of the bar
is suddenly stopped.
occurs when the spike or saw housingis not held
securely against the tree or limb and/or whenLthe
cut is not begun at fullthrottle.
Bpulls the saw forward, and could cause the
operator to lose control
• To avoid Pull-in:
a. Always begin cutting with the engine at full
throttle and the spike or saw housingagainst
the wood.
b. Use wedges made of plastic, wood, or light
alloy (never of steel or iron) to hold the cut
open.
3; PROCEDURE
Practice cutting a few 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 fulll throttle just before entering the cut by squeezing the Throttle
Trigger.

Keep the engine at full throttle the entire time
you are cutting.
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.
Release the throttle trigger as soon as the cut
is completed, allowing the engine to idle. Ifyou
run the saw at full throttle without a cutting
load, unnecessary wear can occur to the
chain, bar, and engine.
Do not put pressure on the saw at the end of
the cut to avoid losing control when the cutis
