you use CPaftsmanchain saw bar oil. IfCraftsman bar oil
is not available,you may use a good grade SAE30 oil
untilyou are able to obtain Craftsman brand.The oilout-
put is automaticallymetered during operation.Your saw
will use approximatelyone tank of bar oil for every tank
of fuel mix.Always fill the bar oil tank when you fill
the fuel tank.
GASOUNE
The two-cycleengine on thisproductrequiresa fuel mixture
of regularunleadedgasoline and a highquality40:1 2-cycle
engineoil(AIR-COOLED) for lubricationofthebeadngs and
othermoving parts. The correctfuel/oilmixtureis40:1 (see
Fuel MixtureChart). Toolittleoilorthe incorrectoiltypewill
cause poorperformanceand may causetheenginetoover-
heat and seize.
Gasoline andoilmustbe pmmixed ina clean approvedfuel
container. Always use fresh regular unleadedgasoline.
This engineiscertified to operate on unleaded gasoline.
IMPORTANT: Experience indicates that alcohol
blendedfuelscalled gasohol (orusingethanolor metha-
nol)can attract moisture, whichleads to oil/gassepara-
tion and formation of acids during storage. Acidic gas
can damage the fuel system of an engine while instor-
age. Toavoidengine problems, thefuel system should
be emptiedbefore storage for 30 daysor longer. Drain
the gastank,then run the fuel outof thecarburetorand.
fuel linesby startingthe engine and lettingit rununtil it
stops. Use fresh fuel next season. See STORAGE
instructionsforadditional information. Never useengine
orcarburetorcleaner productsin thefueltank orperma-
nent damage may occur.
FUEL STABILIZER
Fuel stabilizerisanacceptablealternative in minimizing the
formationoffuelgum depositsduringstorage. Addstabilizer
to gasolinein fuel tank or storagecontainer.Alwaysfollow
the fuel mix ratio found on the stabilizer container. Run
engine at least5 minutesafter addingstabilizertoallowthe
stabilizerto reachthe carburetor.You do not have to drain
thefuel tank forstorage ifyouare usingfuel stabilizer.
CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) Is
speciallyblendedwithfuel stabilizers.Ifyoudo notusethis
