SPECIAL SAFETY SECTION
GUARD AGAINST KICKBACK
Kickbackisa dangerous reactionthat can/eadtosedous
injury. Do not rely only on the safety devices provided
with your saw. As a chain saw user, you must follow
special safetyinstructlonsto helpkeep yourcuttingjobs
free from accident or injury.
_ILKICKBACK WARNING
Kickback can occur when the moving chaincontacts
anobjectat the upperportion ofthetip ofthe guide bar
orwhen the wood closes inand pinchesthe sawchain
in the cut. Contactattheupperportionofthetipofthe
guidebarcan cause the chaintodigintotheobjectand
stop the chain for an instanL The result is a lightning
fast,reverse reaction whichIdckstheguide barupand
back toward the operator, ff the saw chain is pinched
along the top of the guide bar_the guide bar can be
driven rapldiyback towardthe operator.Either oTthese
reactions can cause loss of saw control which can
result in serious personal injury. ................
KICKBACKPATH

REDUCE THE CHANCE OF
KICKBACK
1. Recognize that kickback can happen. With a
basicunderstandingof kickback, you can reduce
the element of surprise which contributes to
accidents.
2. Neverletthemovingchaincontact anyobjectatthe
tip of the guide bar. Figure1.
3. Keep the working area free from obstructions
such as other trees, branches, rocks, fences,
stumps, etc. Figure 2. Eliminate or avoid any
obstructionthat your saw chain couldhitwhileyou
are cutting through a particula_ log or branch.
4. Keep your saw chain sharp and properly ten-
sioned. Followmanufacturer_chainsharpeningand
maintenanceinstru_ons. Check tensionat regular
intervalsw_ththeengines_opped,neverwiththeengine
running. Makesure the bar clampnutsaresecurely
tightenedafter tensioningthe chain. A looseor-dull
chaincanincrease thechanceofkickbacktooccur.
5. Beginand continue cutting at full throttle. Ifthe
chainis movingat a slower speed, there isgreater
chance for kickback to occur,
6. Cut only one log at a time.
7. Useextreme caution when re-entering a previous
cut.
8. Do not attempt plunge cuts.
g. Watch for shifting logs or other forces that could
.....close a cut and pinch or fall into the chain.
10. Use the Reduced-Kickback Guide Bar and Low-
Kickback Chain specified for .yoursaw.

your body from being in a direct line with the
• Cutting chain. Figure 3.
5. Do not overreach. Youcould be drawn or thrown
off balance and/ose control of the saw.
6. Do not cut above shoulder height. It is difficultto
maintain control ofthe saw above shoulder height.

THIS SAW IS 'FOR OCCASIONAL USE ONLY
NOTE: Exposure tovibrationsthrough prolonged useof
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 andcan cause nerve and circulation
damage and tissue necrosis,
An anti-vibration system designed to reduce
enginevibrationis recommended for those using
chain saws ona regular orsustained basis and is
provided on this saw, An anti-vibration system
doesnotguaranteetheavoidanceofWhitefinger
disease, Continual and regular users must
monitor closely their use of chain saws and
physical condition.

E. BAR AND CHAIN LUBRICANT
• The guide bar and cutting chain require con-
stant lubrication in order to remain in
operating condition. Lubrication is provided
by the automatic oiler system when the oil
tank is kept fitled.
-- Lack of lubricant will quickly ruin the bar and
chain.
--Too little lubricant will cause overheating
shown bysmokecomingfrom thechainand/or
discolorationoftheguidebe#mi!_
• Use Sears Bar and Chain Lubricant (#71-36554--
I qt. or 71-36556 -- 1 gal.) 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 flow-
ingfor the oil system topump enoughoil for ad-
equate lubrication.
1. USE THE FOLLOWING:
30°F or above--Lubricant--undiluted.
• 30°F- 0°F --95% Lubricant to
5% Diesel Fuel #1
or Kerosene.
Below OOF _90% Lubricant to
10% Diesel Fuel #1
or Kerosene.

13.
b. Loosen cap slowly; wait for pressure in the
tank to be released before removing the
cap.
c. Fill the oil tank.
d. Reptace the oil cap securely.
3. IMPORTANT POINTS TO REMEMBER
a. Fill the oil tank each time you refill the fuel
tank to ensure there will be sufficient oil for
the chain whenever you start and run the
saw.
b. It is normal for a small amount of oil to ap-
pear under the saw after the engine stops
due to oft draining from the bar and chain,
