SAFETY RULESAND PRECAUTIONS

t

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.

: WARNING! :_:

A. KNOW YOUR SAW

1 Read your Owner's Manual carefully until you

completely understand and can follow all

safety rules and operating instructions before

attempting to operate the unit. : . _i

:2. Restrict the use of your saw to adult users

who Understand and follow the safety rules,

....precautions, and operating instructions

B. PLAN AHEAD

Wear personal protective gear. At-
ways use steel-toed safety foot-

wear with nomsliP soles snug-

.......: fitting clothing :with reinforced

cutting resistant inserts; heavy-duty non'slip

, gloves; appropriate eye protection such as non-

fogging; vented goggles or face screen; an ap-

: ::proved safety hardhat, and sound barriers I ear

- = . plugs or mufflers to protect your: hearing. Regular
users should have hearing _hecked regularly, as

:"chain saw noisemay damage hearing. ' "

' 2. Keepchildren, bystanders, and pets out of the

....work area.:Do not allow other people tobe near

::'the chain saw when starting or operating'the chain

saw_:

3. Do not handle or operate a chain saw when you
are fatigued, ill, or upset; or if you havetaken

.i :alcohol, drugs or medication. You must be in

good physical conditionand mentally aiert. Chain

saw work is strenuous. If you have any condition

that might be aggravated by strenuous work,

check with your doctor before operating a chain

saw.

4. Do not attempt to use your saw during bad
weather conditions such as strong wind, rain,
snow, etc., or during darkness.

5. Plan your sawing operations carefully in ad-

vance. DO not start cutting until you have a ctear

' iw0rkarea, secure footing, and if you are felling

•trees, a planned retreat path. :

GUARD AGAINST KICKBACK ..... ,

Cw

Kickback can lead to dangerous loss of control of

the saw and possiblY cause serious personal in- 1.

jury. Kickback isthe upwardand backward motion of
the guide bar that occurswhen the movingchain con- 2.
tacts an object atthe tip oftheguide bar.

To reduce the hazard of kickback:

1. Hold the saw firmly with both hands. Left hand
on front handle barl right hand on rear handle

whether you are right-handed or left-handed.

Never use the saw with one hand .......

2. Do not overreach.

3. Do not let the tip of theguide bat contact the
ground, another log, branch, Or any other

obstruction.

5. Cut one log atatime.

6. Use extreme caution when. re-entering a pre-

vious cut.

.7. Donot attempt plunge cuts .....

8. Watch for shifting logs' or other forces that

could close a cut and pinch the chain.

9. DO not cut above shoulder height.

10. Follow manufacturer's chain sharpening

and maintenance instructions. Keep the

chain properly tensioned. Check tension at reg-
ular intervals with the engine stopped, never

,,, with the engine, running,-Make: Sure the bar

clamp nuts are secure!y:tightened after !ension-

,, .ingthe chaio.. :.,_ .

11. _Use. the Guard Link. Chain and.. Lo-Kick®
Guide Bar designed foryour saw to reduce the

hazard of kickback. .......... -

D. AVOID REACTIVE FORCES _ .

Pushback and Pull-in occur when the chain is
suddenly stopped by being pinched, caught, or

by :contacting a foreign object in thewood. This
results in a reversal of the chain force used to cut

wood and causes the saw tomove inthe opposite di-

•rection Ofchain rotation, resulting in loss of control
and possible seriouspersonal injury.

To avoid Pushback:

1. Be extremely aware of situations or obstruc-
tions that may cause material to pinch the top of
or otherwise stop the chain.

: 2. Do not cut morethan one log at a time.

3. Do not twist the saw as the bar iswithdrawn
_ from an under-cut when bucking.

To avoid Pull-In: •

Always begin cutting with the engine at full

throttle and the spike against the wood.

Use wedges made of plastic, wood, or light

alloy (never of steel or iron) to hold the cut
open.

E. HANDLE FUEL WITH CAUTION ....

1. Eliminate all sources of sparks or flame in the
areas where fuel is mixed, poured, or stored.

There should beno smoking, open ftames, 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.

4. Move at least 10 feet (3 meters) away from fuel
and fueling site before starting the engine.

5 Do not smoke while handling fuel or while

operating the saw.

6. Turn the engine off and let your saw cool be-

fore removing the fuel tank cap and refueling
the unit.

F. 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 of your body away to the side
of the saw chain protrudingto the leftofcut when

the engine is running.

4. Cut wood Only. Do not use to pry or shove away

limbs, roots or other objects.

5. Make sure the chain will not make contact be-

fore starting the engine. Never try to start the

saw when the guide bar is in aCutor kerr.

6. Use extreme caution when cutting small size

brush and saplings. Slender materialmay catch
the saw chain and be whipped toward you or 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 in the 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 cut is completed.

9. Stopthe engine before setting the saw down.

G, MAINTAIN YOUR SAW :IN GOOD

WORKING ORDER

1. Have all chain saw service performed by your
authorized service dealer center, otherthan 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 topage 22 for correctcarburetor idle ad-

justment instructions.

5. Stop the saw if the chain strikes aforeign ob-

ject. Inspectthe unitand repair orreplace parts as

necessary.

ments.

7.

Never modify your saw in any way. Use Only
attachments supplied or specifically recom-
mended by Sears.

H. CARRY AND YOUR SAW

SAFELY

1. Hand carry the unit with the engine stopped,
the Muffler away from your body, and the Guide

Bar and Chain to the rearcowered preferably with

a scabbard,

2. Before transporting in anyvehicle or storing in

any enclosure, allow your saw to cool com-

pletely, cover the bar and chainand properly se-
cureto avoidturnover, fuel spillage or damage.

3. Drain oil and fuel tank before storing for more

than 30 days.

4. Store ina 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

users should monitor closely their use of chain saws and physical condition.

E. CHAIN TENSION

• COrrect chain tension is very important:

--a loose chain will 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,

• Chain tension is correct when the chain:

--can be lifted about 1/8" 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

when new. Check tension:

:-- each time the saw isused

w more frequently when the chainis new
J as the chain warms upto normal operatingtem-

perature

• The Bar Clamp Nuts must be slightly loose to

tension the chain correctly.

1. Hold the tip of the Guide Bar up and turn the
Adjusting Screw. just until the,chain does not
sag beneath the Guide Bar, Figureg.

'NOTE: Turn screw clockwise to tighten ten-

sion; Turn screw counterclockwise to loosen

tension .....

3. Continue turning the Adjusting Screw until
the tension is correct. _ .

• Your chain saw is powered by a two-cycle

engine which requres a fuel mixture of regu-

_lar gasoline anda high quality engine oil spe-

cially made for 2-cycle, air-cooled engines.
The internal design of the 2-cycle engine re-

quires lubrication of moving parts. Lubrica-
tion is provided when you use the recom-

...... mended mixtureof gasoline and oil, .

• Gasoline must be iclean and not over two
months old. After :a sl_ort period of itime,

: gasoline ,begins to chemically 'break down

and will form compounds that can cause hard
starting and damage in 2-cycle engines.

; • The correct measure of gasoline to oil is very
: important.

:_ --Too much oil in the mixture will =fou! the

........ Spark plug.

........... --Too little oil will cause the engine to over-

heat resulting in damage,

• Mix the fuel thoroughly in a container since
gasoline and oil do not readilycombine. Do not

try to mix fuel directly in the fuel tank.

U'XTURE:

Figure 10

1. USE THE FOLLOWING FUEL MIXTURES:

2. DO NOT USE:

• BIA Oil (Boating Institute of America)

--Does not have proper additives for air-
cooled, 2-cycle engines and could cause

damage.

• AUTOMOTIVE OIL-

- Does not have proper additivesfor 2-cycle
engines and couldcause damage.

• GASOLINE CONTAINING ALCOHOL-

(High Test, Premium or Gasohol)

Stiffens criticalcarburetor fuel metering ele-
ments and causes engine damage from
overheating.

Increases vaporlock.

m Attractswater causing corrosiondamage.

3. HOW TO MIX FUEL

4. IMPORTANT POINTS

a. Pour one-half of the gasoline into an ap-

proved, marked container. Do not try to mix

oil and gasoline directly in the fue! tank.

b. Add entire measure of 2*cycle Engine Oil.
c. Mix.

d. Add remainder of gasoline.
e. Mix thoroughly for one minute.

Figure 11

G. BAR AND CHAIN OIL

• The guide bar and cutting chain require con.
tinuous 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 and/or
discoloration of the guide bar rails.

• Use Sears Bar and Chain Lubricant #71-36554
or clean SAE 30W oil.

In freezing weather oil will thicken, making it
necessary to thin bar and chain oil with a

small amount of Diesel Fuel #1 or Kerosene.

Bar and chain oil must be free flowing for the
oil system to pump enough oil .for adequate

lubrication.

ao 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.

b. Mix, pour and store fuel in an approved,

marked, container and in a well-ventilated
area. Gasoline vapors are harmful to your

health and are a serious fire hazard. Use a fun-
nel or spout when pouring fuel.

c. Avoid overfilling the fuel tank. Allow3/4 inch

for ex pansion. Tighten Fuel Cap securely. Fig-

ure 11.

d. Wipe up all fuel spills. Wipe off any fuel spil-

led on the saw. Completely dry the saw before
using.

e. Move at least 10 feet (3 meters) away from

fueland fueling site before starUng the en-

gine.

1. USE THE FOLLOWING:

30°F or above Lubricant -- undiluted.
30°F - 0° F --

95% lubricant to 5% Diesel

Fuel #1 or Kerosene.

Below 0°F

90% lubricant to 10%

Diesel Fuel #1 or Kerosene.

2. HOW TO FILL THE OIL TANK

a. Stop the engine.
b. Turn saw on its side with oil cap up. Figure

12.

c. Loosen cap slowly and wait for pressure in

the tank to be released before removing the
cap.

d. Fill the oil tank.
e. Replace the oil cap securely.

FILLTHE
TANK EACH

THE FUEL TANK
IS FILLED

Figure 12

3. IMPORTANT POINTS TO REMEMBER

a. Fill the oil tank each time you refill the fuel

tank to ensure there wilt be sufficient oi! for
the chain whenever you start and run the

saw.

b.

The saw will use about 112 tank of chain oil

for each tank of fuel mixture. If tess oil is
used, check for a plugged oil hole in the
guide bar. ; •

C.

It is normal for a small amount of oil to ap-
pear under the saw after the engine stops.

This is due to oil draining from the bar and

chain when not in use.

USING YOUR SAW .... i

A. CONTROL DEVICES

Understanding the control devices on your saw

is an important part of learning how to properly

and safely operate the unit. Figure 13. _

1: The ignition Switch is a!oggte switch which

is moved up for the "Start" position and mov-
ed down for the' "Stop" i_osition.

2. The two-position Choke helps to start the
saw by controlling the air flow to the fuel

system.

3. The Trigger accelerates and controls the
speed of the engine and is designed to be

used with the Throttle Lock.

prevents the Trigger from becoming accident-
ly engaged. The Throttle Lock must be press-

ed before the Trigger can be activated.

5;The Throttle Detent Button holds the Throttle

Lock and Trigger in position while the engine
is being started. Release the Throttle Detent
Button after the engine is started by lightly
squeezing the trigger.

B. STARTING INSTRUCTIONS

C. CONTROLLING KICKBACK ........

Kickback isa dangerous reaction thatcancause
serious personal injury. Carefully study this man-

ual before you make the first cut with your new

saw. "Youmust 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 operator can lose control of the saw
and the cutting chain can cause serious personal

injury if it contacts any part of the body.

Figure 15

AVOID OBSTRUCTIONS

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 occur-

rence.

b. Never let the moving chain contact any ob-

ject at the tip ofthe guide bar. Figure 15.

c. Keep the working area free from obstruc-

tions 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 par-

ticular log orbranch.

d. Keep your saw chain sharp and properly

tensioned. A loose ordull chain can increase
the chance of kickbackl

e. Begin and continue cutting at full throttle.

Ifthe chain is moving_ataslower-speedTthere ..........................!

isgreater chance for kickback tooccur.

f. Cut one log at atime.

g. Use extreme caution when re-entering a

previous cut.
h. Do not attempt plunge 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 Lo-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.

3. MAINTAIN THE BEST CONTROL

a. Keep a good firm grip on the saw with both

hands. Figure 117.A firm grip can neutralize

kickback and help you maintain controlof the

saw. Keep the fingers ofyour lefthand encirc-

ling and your left thumb under the front han-

dlebar. Keep your right hand completely

around the rear handle whether you are right

:handed or/eft handed. Keep your left arm

straight with theelbow locked.

b. Position your left hand on the front han-

dlebar so it is in a straight line with your

right hand on the rear handle. Figure 17.
Never reverse rightand lefthand position.

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 17.

e. Do not overreach. You could be drawn or

thrown offbatance and lose controlofthe saw.

f. Do not cut above shoulder height. It isdiffi-

cult to maintain control of the saw above
shoulder height.

USING THE POWER SHARP®SYSTEM (MODEL 358.356100)

, , , , ,,

• Model 358.356100 is equipped with a Power Sharp ®
:System that will perform approximately 80% of the

sharpening necessary for the saw chain. The Power

Sharp® System uses a built-in grinding stone to shar-

pen the cutter top plates and set depth gauges. As

: the built-in sharpener is used, the cutter side plates

.gradually will be altered. Hand filing is required 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.

• Always replace the sharpening stone when

--sparks are no longer seen at full adjust.

ment

--only 1/4 inch of stone is remaining

--stone hasbecome cracked or damaged.

--a new chain is installed. The used stone

wilt be worn to the shape of::the old chain

and can cause excessive wear to a new
chain. Replacement chain comessupplied

with Stone Cartridge Replacement #69099.
Refer to replacement instructions on page

13.

--saw has to be forced through the cut.

JCAUTION:J ALways wear gloves when handling

the chain. The chain can be sharp enough to cut
you, even when it is too dull to cut wood.

A, AUTOMATIC SHARPENING

1. Stop the engine:

.... 2. Place the saw 'on a solid, flat surface and

make sure that the chain will not contact

any object.

3. Adjust the chain with correct tension. Refer to
Chain Tension page8.

: 'IMPORTANT: The chain must be tensioned

correctly for proper sharpening to occur.

4. Start the engine and operate at half to three/
quarters throttle during steps "5", "6", "7",

and "8".
NOTE: Saw must be running at half to three/

quarters throttle before knob is pressed.

_: 5:Push the Power Sharp ® i Kn0bdown slowly

: Untit fully pressed down. Figure19.

NOTE:If stone should contact chain before

knob is fully pressed down, release knob
and turn knob counterclockwise until condi-

tion does not exist. Repeat :Step "5" again.

6. Turn knob slowly clockwise until sparks can

be seen as shown in Figure 19.

ventional chain is substituted for the Power
Sharp'_. Chain. _See instructionsfor removing the

Stone Cartridge on page 13. Use replacement
chain #71-3638. Follow chainsharpening instruc-
tions onpage 18.

NOTE: Pro per sharPePing occurs when a light

flow of sparks is seen: Im proper sharpening is
shown by a heavy flowof sparks or no sparks.

7. Release knob and turn one additional "click"
clockwise.

NOTE: It is important to turn the knob only
one "click" each time the knob is pressed.
More turnswilt result in making the chain dull
instead of sharp.

8. Press knob firmly against chain and hold for
10-15 seconds or until sparks can no longer

be seen.

9.. Reteaseknoband stop the engine.

10. Inspect chaincutters.
NOTE: A properly sharpened cutter will show

grinding marks across its entire width. Figure

TYPES OF CUTTING .....

Ae BASIC CUTTING TECHNIQUE

1. 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 the unit and repair or replace
parts as necessary.

c. Keep the chain out of dirt and sand. Even a

small amount of dirt will quickly dull a_Chain and
thus, increase the possibility of kickback.

Toavoid Pull-in:

a. Always begin cutting with the engine at full

throttle and the spike against the wood.

b: Use wedges made of plastic, wood, or light

alloy (never of steel or iron) to hold the cut

open.

m

PROCEDURE

Practice cutting a few smalt logs using the follow-

ing technique to get the '_eel" of using your saw
before you begin a major sawing operation.

2. UNDERSTAND REACTIVE FORCES
Pushback and Pull-in occur when the chain is
suddenly stopped by being pinched, caught,

a. Accelerate the engine to full throttle just be-

fore entering the cut by squeezing the Throt-

tleTrigger.

...........................................o.r..by.#ontactinga, fore!gn.obje_ in_the_wood__...........................),....Begin cutting with the spur against the log.

This results in a reversal of the chain force used Figure 26,
to cut wood and causes the saw to move inthe op-

posite direction of chain rotation, resulting in loss

of control and possible serious personal injury.:'.

'e Pushback:

--occurs when the chain on top of the bar, is sud-
deftly stopped When the top of the bar is used for

cutting.

.... drives the saw straigl_t back toward the operator,

poss!bly causingloss of saw control.

To avoid Pushback:

a. Be extremely aware of situations or

obstructions that may cause material to stop
or pinchthe top ofthe chain.

....b. Do not cut more than one log at atime.

c. Keep the engine at full throttle the entire

time you are cutting.

d. Allow the chain to Cutforyou; exert only light

downward pressure. If you force the cut, dam-
age to the bar, chain oreng_necan result.

e. 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 cut-

ting load, unnecessary wear can occur to the

chain, bar, and engine.

f. Do not put pressure oh the saw at the end

of the cut to avoid Iosing controlwhen the cut
iscomplete.

g. Stop the engine before setting the saw

down after cutting.

c. Do not twist the saw as the bar is withdrawn

=" from an under-cut_

e Pull-in:

R occurs when the chain on the bottom of the bar

is suddenly stopped.

-- occurs when the spike orsaw housing isnot held
securely against the tree or limb and/or when the

cut is notbegun atfull throttle.

Figure 26

B. TREE FELLING TECHNIQUES ....

. PLAN YOUR SAWING OPERATION CARE-

FULLY IN ADVANCE

a. Clear the work area. You needa clear area all

around the tree where you can have:secure

footing. • '=: _

b. Studythe natural conditions that can cause

thetree to fall in a particular direction:
1 :) The WIND direction and speed

2.) The LEAN ofthetree :

3.) WEIGHTED with BRANCHESon one side

4.) Surrounding TREES and OBSTACLES

c. Look for decay and r0t. If the trunk is rotted,

itcould snap and falltoward the operator.

d. Check for broken or dead branches which

Could fall on you while cutting.

e: Make sure there is enough room for the tree

to fall. Maintaining a distance of 21/2 tree

lengths from the nearest person or other ob-

jects. Engine noise may drown out warning

carl.

f. Remove dirt, stones, loose bark, nails,

staples, and wire from the tree =where cuts
are to be made.

g. Plan to stand on the up-hill side when cut-

ting on a slope.

h. Plan a clear retreat path to the rear and

diagonal to the line of fall. Figure27.

FELLING SMALL TREES -- LESS THAN

2.

6" IN DIAMETER

a. Ifyou knowthe direction offall:

1.) Make a single felling cut on the side away
from the direction offall.

2.) Cut all the way through.

3.) Stop the saw, put it down, and get away

quickly on your planned retreat path.

If you are not sure which way the tree willfall,
use the notch method described for felling

large trees.

3. FELLING LARGE TREES m 6" DIAMETER

OR MORE

The notch method is used to cut large trees. A
notch is cut on the side of the tree inthe 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.
NOTE: If the tree has large buttress roots, re-

movebefore making the notch. Cut into the but-
tresses vertically, then horizontally, Figure28.
a. Makethe notch cut. Figure29.

1.) Cut the bottom of the notch first, through
1/3 of the diameter of the tree.

2.) Complete the notch by making the slant
cut.

3.) Remove the notch ofwood.

b. Make thefelling cut on the opposite sideofthe

notch about 2" higher than the bottom of the
notch.

c. Leave enough uncut wood between the felling

cut and the notch to form a hinge. Figure 30.
NOTE: The hinge helps to keel5 the tree from
twisting and falling in the wrong direction.

d. Use a wedge if there is any chance that the tree

will not fall in the desired direction.

Figure 27

\

Figure 29 Figure 30

NOTE: Before the felling cut is complete, drive

wedges to open up the cut when necessary to
control the direction of fall. Use wood, plastic or

light alloy wedges but never steel or iron, to
avoid kickback and chain damage.

e. Be alert for signs that thetree is ready to fall:

1.) cracking sounds

2.) widening ofthe felling cut

3.) movement in the upper branches.

f. As the tree starts to fall; stop the saw; put it

down, and get away quickly on yourplanned

retreat path.

g. Be extremely cautious with partially fallen trees

that may be poody supported. When a tree
doesn't falllcomp!etely, set the saw aside and

, pul!down the tree with acable winch,block and

tackle or tractor. Do not cut itdown with your saw
to avoid injury.

C. BUCKING

Bucking is the term used for.cutting a fallen tree to the
desired log size.

1. IMPORTANT POINTS

a. Cut only one log at a time.

b. Cut shattered wood very carefuilyl Sharp

pieces of wood could be flung toward the

operator.

c. Use a sawhorse to cut small logs. Never

allow another person to hold the logwhile cut-

ting and never holdthe logwith your leg orfoot.

d. Give special attention to logs under strain

to prevent the saw from pinching. Make the

first cut Onthe compression side to relieve the
stress on the log. (Figure 31)

e. Do not cut in an area where logs, limbs and

roots are tangled such as in a blown down
area. Drag the logs intoa clear area before cut-

ting by pulling out exposed and cleared togs

....................................................7................................first:............................................................................................_.................................................

f."_Make 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
will tend to bend. The saw can become

.... ' pinched or hung in the log if you make the first

cutdeeper than 1/3ofthe diameter of the log.

2. TYPES OF CUTTING USED Figure 32.

-- Overcutting - begin on the top side of the
log with the spur against the log: exert light

pressure downward.

m Undercutting - begin on the under side of the

logwith the top ofthe saw against the log;exert
light pressure upward. During undercutting,

the saw will tend to push back at you. Be pre-
pared for this reaction and hold the saw firmly

tomaintain control.

WARNING!
Never turn the sawupside down to undercut, The
saw cannot be controlled in this position.

;_ _ ,clutch service too/s. Proper disassembly and

repair of the clutch is extremely important to
the life of the engine and thesafety of the

operator. .....

• Clutch maintenance is requiredwhen:

--the chain continues to turn while engine

idles after the idle speed screw has been
adjusted to its capacity.

--slippage occurs during a cut.

.--a chattering noise occurs during cutting.

• Clean the clutch, drum/sprocket_ and sur-

rounding area daily during heavy, use of the
saw: Check't0 see that the clutch drum turns

freely and Smo0thty.

• Inspect the sprocket regularly for wear. A
worn sprocket will make the chain run er-
ratically and will Shorten the life of the bar

and chain. Figure 52.

• Replace the sprocket whenever a new chain

is installed in order to gain the full life ex-
pectancy of the chain. Use the following pro-

./cedure:. _ _
