WARNING
Kickback
Path
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 SERIOUS 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.

•
•
•
Recognize that kickback can happen. With a basic
understandingof kickback, you cen reducethe element
of surprise which contributes to accidents.
Never let the moving chain contact any object at the
tip of the guide bar. Figure 2.
Keep the working area free from obstructions such
as other trees, branches, rocks, fences, stumps, etc.
Figure 3. Eliminate or avoid any obstructionthat your
chain could hit while you are cuttingthrougha particular
log or branch.
Keep your chain sharp and properly tensioned. A
loose or dull chain can increase the chance of kickback
to occur. Follow manufacturer'schain sharpening and
maintenance instructions. Check tension at regufarinterva{s with the engine stopped, never with the engine
running. Make sure the bar clamp nuts are securely
tightened 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.
Cut one log at a time.
Use extreme caution when re-entering a previous
cut.
Do not attempt plunge cuts.
Watchforshiftinglogsorotherforoesthatcouldclose

, Stopthe saw ifthe chain strikes a foreign object. Inspect
the saw and repair or replace parts as necessary.
• Keep the chain cut of dirt and sand. Even a small
amount of dirt wilt quickty dull a chain and thus increase
the possibility of kickback.
To get the _eel" of usingyour saw before you begin a major
sawing opera, on, practice cutting a few small togs usingthe

CAREFULLY REENTER THE CUT. TO
AVOID KICKBACK AND CHAIN DAMAGE,
DO NOT USE A METAL WEDGE, DO NOT

KICKBACK
CAN OCCUR WHEN Tile
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 3"HE 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

RAPIDLY BACK TOWARD THE!OPERATOR.
EITHER OF THESE REACTIONS
CAN
CAUSE LOSS OF SAW CONTROL WHICH
CAN RESULT IN SERIOUS INJURY.

PINCH FORCES
Pinch-Kickbackand PulHn occur when the chain issuddenly stoppedby being pinched, caught, or by contacting aforeign 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. PuU-tnpulls
the saw away from the operator. Eitherreaction can result in loss of control and possibly serious injury.
TO AVOID PINCH-KICKBACK:
* Be extremely aware of situationsor obstructionsthat
can cause rnatedal to pinch the top of or otherwise
stop the chain.
o Do not cut more than one log at a time.

TO AVOID PULL-IN:

DETERMINE
THE NATURAL FALL DIRECTION
•
Wind-A tree evenlybalanced willfall in the same direction the wind is blowing.
• Lean - Use a carpenter's level or plumb bob to determine if tree has a naturallean. A leaning tree willtend to
fall in direction of lean.
• Shape - A tree willtend to fail towards sidethatis more
heavily branched.
• Other Factors- Contacting or nearbytrees, buildings, or
wires can influence the direction the tree willfall.
CUTTING
PROCEDURE
(Fig. 23 )
After determining the Natura! Fall Direction,the tree should
be cul as foliows:
IMPORTANT: BEFORE FELLING A TREE, MAKE SURE
YOU HAVE AT LEAST 3 FELLING WEDGES AND A MAUL
(HAMMER) AVAILABLE FOR USE IF NEEDED.
,
•
•
•
•
-
Use some means to visually mark the Natural Fall
Direction.
Mark your notch cut on the Natural Fall Direction side of
the tree approximately 18-24 inches above the ground.
Cut top of the notch first at a 45 degree angle. Saw
through 1/3 of the width of the tree.
Cut bottom of the notch at a 45 degree angle until you
meet the top notchcut Remove notch of wood.
On the side of the tree oppositethe notch cut, make the
felling cut. The felling cut should be 2 inches above the
center point of the notch cut. Before the felling cut is
complete, use wedges to open the cut when necessary
to control the direction of the fall. Use wood or plastic
wedges, but neversteel or iron, to avoid idckback and
chain damage.
Cracking sounds, widening of the felling cut, movement
in the upper branches are all signs that the tree is ready
to fall.
As tree begins to fall, turn off saw, set it down, and move
quickly away from direction of fall.
if your chain saw binds in the felling cut, you have three options:
• If the wrong directionof fall is acceptS, le, c_ietully re:.
move the felling wedge, Cut deeper in me notchsioe ot
the tree untiltree startsto fall.
• If the wrong directionof falt is not ac.c.
eptable,.a_empt.to
use one or more felling wedges to mrce the tree in.me
original direction of fall Do so by ddving the weoges
deeper into the fellingcut,
• Keep everyone away from the tree in all directionsand
then seek professionalhelp!
NOTE: For trees less than 6 inches in diameter, make a
single felling cut on the side away from the direr."on of _1!.
Cut through untiltree begins to fall. Then turn o_s_.w,smn
down, and move quickly away from direction oTra_.
OPERATION
°
USE/TIPS
Clear the work area of debris where you can have secure footing.
* Make sure there is enough room forthetree to fall. Maim
taJn adistance of 21/2 tree lengths fromthe nearest person or other objects. Engine noise can crown out a
warning call.
• Remove dirt,stones, loose bark, nails,staples, and wire
from the tree where cuts are to be made.
° Plan to stand on the up-hil! side when Gutting on a slope.
- Plan a clear retreat path to the rear and diagonal tothe
line of fall.
, If unsure about which way a tree will fall, use the notch
cutting method.
• Large buttress roots should be removed prior to notch
cut.
, Use a wedge if there is any chance that the tree will not
fall in the desired direction.
, We recommendycu cut branches below shoulder height
before felling tree. (See Limbing and Pruning).
Be alert to signs that the tree is ready to fall:
• Crackingsounds.
• Widening of theie|lirtg'c'_:
• Movement in the upper branches..

GUIDE BAR AND CHAIN OIL
For maximum guide bar and chain life, we recommend you
use Craftsman chain saw bar oil. If Craftsman bar oil is not
avaJlable, you may use a goodgrade SAE30 oiluntil you are
able to obtain Craftsman brand. The oil output is automaticallymetered during operation. Your saw willuse one tank of
baroil for every tank of fuel mix. Always fill the bar oil tank
when you fill the fuel tank.
Fuel stabilizer isan acceptable alternative in minimizing the
formationof fuel gum depositsdudngstorage.AddstabilLzer
to gasoline in fuel tank or storage container.Always follow
the fuel mix ratio found on the stabilizer container. Run
engine at least 5 minutesafteradding stabilizerto allow the
stabilizer to reach the carburetor.You do not have to drain
the fuel tank for storage if you are usingfuel stabilizer.
CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is
speciallyblended with fuel stabilizers.Ifyou do not use this
Sears oil, you can add a fuel stabilizer (such as Craftsman
No. 33500) to your fue! tank,
2-CYCLE OIL:

ratio40:1.
IMPORTAN'13 Do not use:
• AUTOMOTIVE OIL
• BOAT OILS (NMMA, BIA. etc.)
These oils do not have proper additives for 40:1 2-cycle
engine oil (AIR-COOLED) engines and can cause
engine damage.
GASOLINE
The two-cycle engine on thisproductrequiresa fuel mixture
of regular unleaded gasolineand a high quality40:1 2.-cycle
engine oil (AIR-COOLED) for lubricationof the bearings and
other moving parts. The correctfueVo_ mixture is40:1 (see
Fuel Mixture Chart). Too t_le oil or the incorrect oiltype will
cause poor performance and may causethe engine to overheat and seize.
Gasoline and,oil must be premixed in a clean approved fuel
container. Always use fresh regular unleaded gasoline.
Thisengine hasbeen certified to operateon unleaded gasoline and Craftsman 40:1 2-cycle engine oil(AIR-COOLED).
IMPORTANT:
Experience indicates that alcohol
blended fuels caIled gasohol (or using ethanol or methanol) can attract moisture, which leads to oiVgas separation and formation of acids during storage. Acidic gas
can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should
be emptied before storage for 30 days or longer. Drain
the gas tank, then run the fuel out of the carburetor and
fuel lines by starting the engine and letting it run until it
stops. Use fresh fuel next season_. See STORAGE
instructions for additional information. Never use engine
or carburetor cleaner products in the fuel tank or permanent damage may occur.
GASOLINE
AND OIL MIXTURE
MIX GASOLINE AND OIL AS FOLLOWS:
• Consult cha.,tfor correctquarr_ies.
• Do not mix gasoline and oil directly in the fuel tank.
FOR ONE GALLON:
• Pour 3.2 ounces of high quality, 2-cycle engine oil
(AIR-COOLED) into an empty, approved one gallon
gasoline container.
• Add one gallon of regular unleaded gasoline to the
gallon container, then securely replace the cap,
Shake the container momentarily.
o The mixture is now readyfor use. Fuel stabi{izercan
be added at this time if desired;follow mixing ins'mJCtions on the label.
