GUARDAGAINST. KIC KBACK
KickbackJsa dangerous reaction that(an le_d tosedous
personal injury. Do notreJy only on the safety devtces pto-
vided withyoursaw. As a chain saw user, you must take
special safety pre_utions to help keep your cutting jobs
free from accident or injury.
!"' _I_KICKBACK WARNING
Kickbackcanoccurwhenthe moving chain contacts
an object at the upper portion of the tip of thegu Ide bar
or whenthe wood closes Inand pinches thesewchain
ln the cut _Contact at the upperportion of tim tip ot the
guideba_can cause thechain to dig tntothe object and
stop the_haln foran Instant. The_result Is alightning
fast, teVetse reaction,whlch kicks the guldebar up and
back toward the operator. If the saw chain is pinched
along th_ top of the guide bai; the guide bar can be
driven rapidly back toward the operator. Either of
these reactions can cause loss of saw control which 1
can msult in serious injury, j
KICKBACK PATH
.................. ! ...........
REDUCING K,ICKIM, CK
1. Recognize that kickback can happen. With a
basic understanding of kickback, you can reduce
the element of surprise which contributes to
accidents.
2. Ne_r let the moving chain contact any object atthe
tlpof the guide bar. Figure 1.
3. Keep the working area free from obstructions
such as other trees, branches, rocks, fences,
stumps, etc. Figure 2. Eliminate or avoid any
obstruction that your saw chain could hit while you
are cutting through a particular log or branch.
4. Keep your saw chain stzarp and properly ten-
sloned. FotlowSears chain sharpening and mainte-
nance in_rucg0ns:(3heck tension at regular intervats
withthe engine stopped, neverw_ththe engine running.
Make sure the bar cJampnuts are securely tightened
after tensicningthe chin. A loose or duli chain can
increase the chance of kickback.
5. Begin and continue cutting at full throttle. If the
chain-is movi_'_ga'_a slow_, speed, there is greater
chance for kickback,
6. Cut only one log at a time.
7. Use extremecaution when re-entering a cut,
8. Do not attempt piunge cuts,
9. Watch forshifting logs orotherforcesthat could
close a cut and pinch or Pall into the chain.
10. Use only the Reduced-Kickback Guide Bar and
Low-Kickback Chain specified for your saw.

• In freezing weather oil will thicken, making
it necessary to thin bar and chain oil withe
small amount of Diesel Fuel #I or

TYPES OF CUTTING
A. BASIC CUTTING TECHNIQUE
1. IMPORTANT POINTS.
a. Cut wood only. Do not cut meta!, plastk_s,
rnasorm/,non-woodbuildingmatenals,et¢.Donot
useyour saw_opryorshove awaylimbs, rootsor
otherobjects.
b. Stop the saw if the chain strikes a foreign
object. Inspect ",heunit and repair or replace
parts asnecessary.
c. Keep the ChainOUtof dirt and sand.Even a
smaitamount ofdirtwillquicklydulla chainand
thus,increasethepossibilityof kickback.
KICKBACK WARNING
Kickback canoccurwhen the movingchain contactsan
ob]ectat tlte-upperportion of the tip orthe guide baror
when _hewood closes in and pinches the sawchain in
the cut.Contact at the upper portion of the tip of the
guide bar claShcausethe chainto dig into theobject and
stop the chain fora_ instant. The result is alightning
fast, reverse reaction which kicks the guide bar upand
back toward the operator. If the saw chain ispinched
along the top of the guide bar, the guide bar can be
driven rapidly backtoward the operator. Either ofthese
reactions can cause loss of saw control whichcan
result in serious injury.
2. UNDERSTAND REACTIVE FORCES

the logs into aciear _r_before cutting.
Make the first bucking cut 1/3 of the way
through the log and finish with a 2i3 cut on
the opposite side. As the log is being cut, it wil|
_end to bend. The saw can become pinched or

2. GUIDE BAR MAINTENANCE
• Conditions which can require guide bar
maintenance:
_saw cuts to one side
--saw has to be forced through a cut
--inadequate supply of oil to bar and

• Check the condition of the guide bar each
time the chain is sharpened. A worn guide
bar will damage the chain and make cut-
ting more difficult.
• Replace the guide bar when:
--the inside groove of the guide bar rails is
WON'I.
--the guide bar is bent 0rcracked.
• Use only the ReducedJ<ickback Guide Bar
specified for your saw in "Specifications" for
replacement.
a. Remove the guide bar to Service.
b. Clean oil-holes at least once for each five
hours Of operation:Figure 34,
c. Remove Sawdust from the guide bar
groove periodically witt_ a putty knife or
a wire, Figure 34,

E. CLUTCH AND DRUM/SPROCKET
_II_WARNING
Do not start engine without Guide Bar, Chain, and Bar
Clamp Housing completelyassembled. The clutch can
come off without the g uide bar and chain completely
assembled and serious injury can result. The clutch
•shoes and drum can separate causing the clutch to
violently fly apart and serious injury can result.
• Take the saw to your Seam Service Center for
full clutch inspection and service after each 100
hours of operation, itis recommended thatyou do
notttyto service the dutch or dtum/sprocketyourself
unless you are a competent small engine mechanic
and'have the proper clutch service tools.Proper dis-
assemblYat_d repair of the clutch is extremelyimpor-
tant to the:!ife of the engine and _e safety of the
operator.
• Clutch maintenance is required when:
-- 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 surrounding
area daily during heavy use of the saw. Check to see
that the dutch drum turns freely and smoothly.
• Inspect the sprocket regularly for wear. A worn
sprocket will make the chain run er_aticaJly and wilt
shorten the life of the bar and chain: Figure 42.
• Always have a worn sprocket replaced by your
Sears Service Center whenever a new chain is
installed in order to gain full life expectancy of
the chain.
"H""" • '' I" 'ii
F. AIR FILTER
• A dirty air filter:
-- reduces cutting power
m increases fuel consumption
• Clean the air filter:
frequently, especially in very dus_ cond'_ons.
always after 10 tanks of fuel mixture or 5 hours
of operation, whichever is less.
• Replace the air filter ifany damage occum toit,
jCAUTION:j Never operate the unit without the
air filter in place to avoid damage to the engine.
Items Required: soft bristled brush, such as apaint
brush.
1. Clean off ther..aYouretorcover and the area around it.
2. Pull choke to the ful}position (Figure 14, page 11)to
prevent dirtfrom entering the carburetor.
