McCulloch 441 442 Chainsaw Owners Manual

S  Do not operate a chain saw that  is dam-
aged,  improperly adjusted,  or  not com-
pletely and securely assembled.  Always
replace bar, chain,  hand guard, or chain
brakeimmediately ifit becomes damaged,
broken or is otherwise removed.
S  With the engine stopped, hand  carry the
chain saw with the muffler away from your
body, and the guide bar and chain  to the
rear, preferably covered with a scabbard.
S  Rotational Kickback can occur when the
moving chain contacts an objectat theup-
per tip of the guide bar. This  contact 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 to-
ward the operator.
S
Pinch-Kickback can occur when the the
wood closes  in and pinches  the moving
saw chain in the cut  along the top of the
guide bar and the saw chain  is suddenly
stopped.  This  sudden  stopping   of  the
chain results  in  a reversal  of the  chain
force used  to cut wood  and causes  the
sawtomoveintheoppositedirectionofthe
chain rotation. The saw is driven straight
back toward the operator.
MAINTAIN YOUR SAW IN GOOD
WORKING ORDER
S  Have all chain saw service performed by a
qualified service dealer with the exception of
theitems listedinthemaintenancesectionof
this manual.  For example, if improper tools
are  used to  remove or  hold the  flywheel
whenservicingtheclutch,structuraldamage
to the flywheel can occur and cause the fly-
wheel to burst.
S  Pull-In can occur  when the moving  chain
contacts a foreign object in the wood in the
cutalongthebottom  ofthe  guidebar andthe
saw chainis suddenly stopped. This sudden
stopping pulls  the saw  forward and  away
fromtheoperator  and couldeasily causethe
operator to lose control of the saw.
S  Make certain the saw chain stops moving
when the throttle trigger is released.  For
correction, refer  to CARBURETOR  AD-
JUSTMENTS.
S  Never modify your saw in  any way. Use
only attachments supplied  or specifically
recommended by the manufacturer.
S  Keepthehandles  dry,clean, andfree ofoil
or fuel mixture.
S  Keep fuel and oil caps, screws, and fas-
teners securely tightened.
S  Use only McCullochR  accessories andre-
placement parts as recommended.
HANDLE FUEL WITH CAUTION
S  Do not smoke while handling fuel or while
operating the saw.

the areas where fuel is mixed  or poured.

tions thatcancausematerial  topinch thetop
of or otherwise stop the chain.
S  Do not cut more than one log at a time.
S  Do not twist the  saw as the  bar is  with-
drawn from an undercut when bucking.

ground; store fuel in a cool, dry, well venti-
lated place; and use an  approved, marked
container for all fuel purposes.  Wipe up all
fuel spills before starting saw.
Avoid Obstructions
S  Move at least 10 feet (3 meters) from fuel-
ing site before starting engine.
Clear The
Working Area
S  Turn the engine off and let saw cool  in a
non-combustible area, not on dry leaves,
straw, paper, etc. Slowly remove fuel cap
and refuel unit.
S  Storetheunitandfuelinanareawherefuel

flames from water heaters, electric motors
or switches, furnaces, etc.
REDUCE THE CHANCE OF
KICKBACK
S  Recognize  that  kickback  can  happen.
With a basic  understanding of kickback,
you can  reduce the element  of surprise
which contributes to accidents.
S  Never letthemovingchaincontactanyob-
ject at the tip of the guide bar.
KICKBACK
S  Keep the working  area free from  obstruc-
tions such as other trees, branches, rocks,
fences, stumps, etc. Eliminate or avoid any
obstruction that  your  saw chain  could hit
while you are cutting through a particular log
or branch.
S  Keep your  saw chain  sharp and  properly
tensioned. Alooseordullchaincanincrease

tenanceinstructions.  Checktensionatregu-
