GUIDE BAR AND CHAIN OIL
The chain citer provides continuous lubrication to the chain and guide bar, Be
sure to fill the bar oil tank when you fill
the fuel tank (Capacity = 6.8 fl, oz.).
For maximum guide bar and chain life,
we recommend you use Craftsman
chain saw bar oil. if Craftsman bar oil is
net available, you may use a good
grade SAE 30 oil until you are able to
obtain Craftsman brand. The oil output
is automatically metered during operation, Your saw will use approximately
one tank of bar oil for every tank of fuel
mix. Always fill the bar oil tank when
you fill the fuel tank.
FUELING ENGINE

gasoline and oil at a ratio of 40:1 (A
40:1 ratio is obtained by mixing 3:2
ounces of oil with 1 gallon of unleaded
gasoline). DO NOT USE automotive oil
or boat oil. These oils will cause engine
damage. When mixing fuel foltow the

OPERATING
TIPS
- Check chain tension before first use
and after 1 minute of operation. See
Chain Tension in the Maintenance
section,
• Cut wood only. Do not cut metal, plastics, masonry, non-wood building materials, etc,
• Stop the saw if the chain strikes a foreign object, inspect the saw and repair parts as necessary.
. Keep the chain out of dirt and sand.
Even a small amount of dirt
will quickly dull a chain and increase the possibility of kickback.
• Practice cutting a few small logs using
the following steps. This will help you
get the ffeeI" of using your saw before
you begin a major sawing operation.
• Squeeze the throttle trigger and allow the engine to reach full speed
before cutting.
• Begin cutting with the saw frame
against the tog.
Keep the engine at full speed the
i entire time you are cutting.
Allow the chain to cut for you. Exert
only light downward pressure.
• Release the throttle trigger as soon
as the cut is completed, allowing the
engine to idle. If you run the saw at
full throttle without a cutting load,
unnecessary wear can occur.
• To avoid losing oontrot when cut is
complete, do not put pressure on
sat,' at end of cut.
, Stop engine before settingsaw down.
TREE FELLING TECHNIQUES
WARNING: Check for broken or dead
branches which can fall white cutting
causing serious injury. Do not cut near
buildings or electrical wires if you do not
know the direction of tree fall, nor cut at
night since you will not be able to see
well, nor during bad weather such as
rain, snow, or strong winds, etc.
• Carefully plan your sawing operation
in advance,
• Clear the work area. You need a clear
area all around th_ tree so you can
have secure footing.
• Study the natural conditions that can
cause the tree to fall in a particular
direction. These conditions include:
• The wind direction and speed.
• The lean of the tree. The lean of a
tree might not be apparent due to
uneven or sloping terrain. Use a

FELLING LARGE TREES
(6 inches in diameter or larger)
The notch method is used to feII large
trees, A notch is cut on the side of the
tree in the desired direction of fall. After
a feliing cut is made on the opposite
side of tree, the tree will tend to fall in
the direction of the notch.
NOTE: tf tree has large buttress roots,
remove them before making the notch.
NOTCH OUT AND FELLING TREE
• Make notch cut by cutting the top of
the notch first, Cut through 1/3 of the
diameter of the tree. Next complete
the notch by cutting the bottom. See
illustration. Once the notch is cut, remove the wedge of wood from tree.
Fina!cuthere

-\
Hinge
. After removing the wood, make the
felling cut on the opposite side of the
notch, This is done by making a cut
about two inches higher than the center of the notch. This wiil leave
enough uncut wood between the felting cut and the notch to form a hinge.
This hinge will help prevent the tree
in the wrong direction.

Opening of
felling cut
NOTE: Before felling cut is complete,
use wedges to open the cut when
necessary to control the direction of fall,
To avoid kickback and chain damage,
use wood or ptastic wedges, but never
steel or iron wedges.
• Be alert to signs that the tree is ready
to fall: cracking sounds, widening of
the fetiing cut, or movement in the upper branches,
• As tree starts to fall, stop saw, put it
down, arid get away quickly on your
planned retreat path.
• Be extremely cautioL_swith partially
fallen trees that may be poorly supported. When a tree doesn't fall completely, set the saw aside and pult
down the tree with a cable winch,
block and tackle, or tractor, Do not
use your saw to cut down a partially
fallen tree,
CUTTING A FALLEN TREE
BBUCKING)
ucking is the term used for cutting a
fallen tree to the desired log size,
WARNING:
Do not stand on the log
being cut. Any portion can roll causing
loss of footing and control. Do not stand
downhill of the tog being cut.
IMPORTANT POINTS
• Cut only one log at a time.
• Cut shattered wood very carefully;
sharp pieces of wood could be flung
toward operator.
• Use a sawhorse to cut small logs.
Never altow another person to hold
the log while cutting and never hold
the log with your leg or foot.
• Do not cut in an area where logs,
limbs, and roots are tangled. Drag logs
into a clear area before cutting them.
BUCKING TECHNIQUES
WARNING:
If saw becomes pinched
or hung in a log, don't 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
orwood
into the cut until the saw can be
removed easily. Restart saw end carefully

CLEAN FUEL FILTER
To clean fuel filter, drain your unit by
running dry of fuel, remove fuel cap!retainer assembly from tank. Pult filter
from tank and remove from line. Clean
with mild detergent and rinse. Dry thoroughly, reassemble.
CARBURETOR
ADJUSTMENT
WARNING: The chain will be moving
during most of this procedure. Wear
your protective equipment and observe
alf safety precautions. During the low
speed mixture adjustment recheck idle
speed after each turn of the screw. The
chain must not move at idle speed,
Carburetor adjustment is critical and if
done improperly can permanently damage the engine as well as the carburetor, If you require further assistance or
are unsure about performing this procedure, call our customer assistance help
line at 1-800-235-5878.
Otd fuel, a dirty air tilter, dirty fuel filter,
or flooding may give the impression of
an improperly adjusted carburetor.
Check these conditions before adjusting the carburetor.
The carburetor has been carefully set at
the factory, Adjustments may be necessary if you notice any of the following
conditions:
• Chain moves at idle. See "Idle Speed"
under adjusting procedure.
• Saw will not idle, See "Idle Speed"
and "Low Speed Mixture"under, adjusting procedure.
° Engine dies or hesitates when it
should accelerate. See "Acceleration
Check" under adjusting procedure.
• Loss of cutting power. See High
Speed Mixture H" under adjusting
procedure.
There are three adjustment screws on
the carburetor. They are labeled H, L,
and ToThey are located in the area }ust
above the pdmer bulb.
CARBURETOR
PRESETS
When making adjustments, do not force
the plastic limiter caps beyond the
stops or damage will occur.
If carburetor presets are not needed,
proceed to "idle Speed-T."
. Turn both mixture screws counterclockwise until they stop.
• Turn the idle speed screw clockwise
until it stops. Now turn counterclockwise 4.1/2 full turns.
Start motor, let it run for 3 minutes, and
proceed to the adjustment section. If
engine does not start, refer to troubleshooting chart or call 1-800-235-5878.
If engine performance is acceptable at
the preset positions and there _sno
chain movement at idle, no further adjustment is necessary.
ADJUSTING
PROCEDURE
Idle Speed-T
Allow engine to idle, Adjust speed until
engine runs without chain movement or
stalling,
• Turn clockwise to increase engine
speed if engine staIIs or dies.
• Turn counterclockwise to decrease
speed.
No further adjustments are necessary if
chain does not move at idle speed and
if performance is satisfactory.
Low Speed Mixture-I.
Allow engine to idle. Then accelerate
the engine and note performance. If engine hesitates, bogs down, or smokes
during acceleration, turn mixture screw
clockwise in 1/16-turn increments until
performance is satisfactory, Repeat this
procedure as necessa_i for proper adjustment. After completIng adjustments,
check for acceleration and chain movement at idle. Reset if necessary.
High Speed Mixture-H
DO NOT operate engine at full throttle
for prolonged periods while mak;ng adjustments. Damage to the engine can
occur. Make a test out. Based on performance of the saw while cutting, adjust the high speed mixture setting in
1/16-turn increments as fol]o,,vs:
• Clockwise until saw has good power in
the cut with no hesitation. Do not adjust
by sound or speed, but judge by how
well the saw performs in the cut.
° Counterclockwise if the saw has
speed, but dies in the cut or lacks
power in the cut.
After completing adjustments, check for
acceleration and chain movement at
idle. Reset if necessary.
Acceleration Check
If the engine dies or hesitates instead of
accelerating, turn the Iow speed mixture
adjustment counterclockwise until you
have smooth acceleration with no chain
.movement at idle. Recheck and adjust as
necessary for acceptable performance.
