OPERATE YOUR SAW SAFELY
• Do not operate a chain saw with one hand. Serious
injury to the operator, helpers, bystanders or any combi-
nation of these persons may result from one-handed
operation. A chain saw is intended for two-handed use.
• Operate the chain saw only in outdoor areas.
• Do not operate saw from a ladder or in a tree, unless
specifically trained to do so.
• Position all parts of your body to the left 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 try to start the
saw when the guide bar is in a cut or kerr.
• 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 inthe wood fibers is released.
• Do not put pressure on the saw at the end of a cut.
Applying pressure can cause you to lose control when
the cut is compJeted.
• Stop the engine before setting the saw down.
• Keep fuel and oil caps, screws, and fasteners
securely tightened.
i..¢1 iii i1=
MAINTAIN YOUR SAW IN GOOD
WORKING ORDER
• Have all chain saw service performed by your Sears
Service Center with the exception of the items listed in
the customer responsibilities 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.
• Make certain the saw chain stops moving when the
throttle trigger is released. For correction, refer to
,'Carburetor Adjustments."
• 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.
• Never modify your saw in any way. Use only attach-
ments supplied or specifically recommended by the man-
ufacturer.
TRANSPORTING AND STORAGE
• Stop the unit before transporting.
• Allow the engine to cool, cover the bar and chain, and
secure the unit before storing or transporting in a vehicle.
• Empty the fuel tank before storing or transporting the
unit. Use up any fuel left in the carburetor by starting the
engine and letting the engine run until it stops.
• Store unit and fuel in an area where fuel vapors cannot
reach sparks or open flames from water heaters, electric
motors or switches, furnaces, etc.
• Store unit so the chain cannot accidentally cause injury.
• Store the unit out of the reach of children.

GUARD AGAINST KICKBACK - Kickback is a dangerous reaction that can lead to serious injury.
KICKBACK WARNING:
KICKBACK CAN OCCUR 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
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, WHICH STOPS
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
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 SERI-
OUS 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
CUTTING JOBS FREE FROM ACCIDENT
OR INJURY.

vals with the engine stopped, never with the engine run-
ning. Make sure the bar clamp nuts are securely tight-
ened after tensioning the chain.
• Begin and continue cutting at full throttle, If the chain
is moving at a slower speed, there is greater chance for
kickback to occur.

KICKBACK SAFETY FEATURES
_ WARNING:
Reduced-Kickback Guide Bar, designed with a small
radius tip which reduces the size of the kickback danger
zone on the guide bar tip. Figure 5. A Reduced-Kickback
Guide Bar is one which has been demonstrated to signifi-
cantly reduce the number and seriousness of kickbacks
when tested in accordance with ANSI B175.1-1991.
• Low-Kickback Chain, designed with a contoured depth
gauge and guard link which deflects kickback force and
allow wood to gradually ride into the cutter. Figure 5.

UNDERSTANDING REACTIVE FORCES
Pinch-Kickback and Pull-In occur when the chain is
suddenly stopped by being pinched, caught, or by con-
tacting a foreign object in the wood. This sudden stop-
ping of the chain results in a reversal of the chain force
used to cut wood and causes the saw to move inthe oppo-
site directionof the chain rotation,Either reactioncan result
in lossof controland possible serious injury.
• Pinch-Kickback
- occurs when chain on top of guide bar is suddenly
stopped.
- rapidly drives saw straight back toward operator.
° Pull-In
- occurs when the chain on the bottom of the guide
bar is suddenly stopped.
- pulls the saw rapidly forward,

• Handguard, designed to reduce the chance of your left
hand contacting the chain if your hand slips off the front
handlebar.
• Position front and rear handlebars, designed with dis-
tance between handles and "in-line" with each other. The
spread and "in-line" position of the hands provided by this
design work together to give balance and resistance in
controlling the pivot of the saw back toward the operator
if kickback occurs.

CUTTING TECHNIQUES (Fig. 20 & 21)
• Overcutting - begin on the top side of the log with the
bottom of the saw against the log; exert lightpressure
downward.
• Undercutting - begin on the under side of the tog 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 control.
Front Saw Frame"
Figure 21
CUTTING SPEED
• Accelerate engine to full throttle before entering cut by
squeezing the throttle trigger.
• Never cut with engine at partial throttle speed.
OPERATION USE/TIPS
• Cut wood only. Do not cut metal; plastics; masonry;
men-wood building materials; etc.
• Stop the saw if the chain strikes a foreign object.
Inspect the saw and repair or replace parts as neces-
sary.
• Keep the chain out of dirt and sand. Even a small
amount of dirt will quickly dull a chain and thus
increase the possibilityof kickback.
To get the "feel" of using your saw before you begin a
major sawing operation, practice cutting a few small logs
using the following technique:
• Accelerate engine to full throttle before entering cut by
squeezing the throttle trigger.
• Begin cutting with the saw frame against the tog.
- Keep.engine at full throttle during cutting procedure.
° Allow the chain to cut for you; exert only light down-
ward 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 com-
pleted, allowing the engine to idle. If you run the unit at
full throttle without cutting, unnecessary wear can
occur to the chain, bar, and engine.
°
To avoid losing control when completing the cut, do
not put pressure on the saw during the end of the cut.
Stop engine before setting unit down after operation.

GENERAL SAFETY
WARNING:
IF SAW BECOMES PINCHED OR HUNG IN A
LOG, DO NOT TRY TO FORCE IT OUT. YOU
CAN LOSE CONTROL OF THE SAW
RESULTING IN INJURY AND/OR DAMAGE
TO THE SAW. STOP THE SAW, DRIVE A
WEDGE OF PLASTIC OR WOOD INTO THE
CUT UNTIL THE SAW CAN BE REMOVED
EASILY. RESTART THE SAW AND
CAREFULLY RE-ENTER THE CUT. TO
AVOID KICKBACK AND CHAIN DAMAGE,
DO NOT USE A METAL WEDGE. DO NOT
ATTEMPT TO RE-START YOUR SAW
WHEN IT IS PINCHED OR HUNG IN A LOG.
KICKBACK CAN OCCUR 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 OPERA-
TOR. EITHER OF THESE REACTIONS CAN
CAUSE LOSS OF SAW CONTROL WHICH
CAN RESULT IN SERIOUS INJURY.
AVOID REACTIVE PINCH FORCES
Pinch-Kickback and Pull-in occur when the chain is sud-
denly stopped by being pinched, caught, or by contact-
ing a foreign object in the wood. This sudden stopping of
the chain results in a reversal of the chain force used to
cut wood and causes the saw to move in the opposite
direction of the chain rotation. Pinch-Kickback drives the
saw straight back toward the operator. Pull-In pulls the
saw away from the operator. Either reaction can result in
loss of control and possibly serious injury.
TO AVOID PINCH-KICKBACK:
• Be extreme_ aware of situations or obstructions that
can cause material to pinch the top of or otherwise
stop the chain.
° Do not cut more than one log at a time.
° do not twist the saw as the bar is withdrawn from an
under-cut when bucking.
TO AVOID PULL-IN:
• Always begin cutting with the engine at full throttle and
the front saw frame against the wood.
• Use wedges made of plastic or wood, (never of metal)
to hold the cut open.
