Low Speed M ixture-L
Allow engine toidle. Then accelerate
the engine and note performance. If
engine hesitates, bogs d own, or
smokes during acceleration, turn low
speed m ixture screw (L) c lockwise in
1/16-turn increments until performance
issatisfactory. Repeat this procedure
asnecessary forproper adjustment.
After completing adjustments, check
foracceleration and chain m ovement
atidle. Reset ifnecessary.
High Speed M ixture-H
DO NOT o perate engine atfull t hrottle
forprolonged periods while making ad-
justments. Damage totheengine can
occur. Make a test c ut. B ased onper-
formance ofthe saw while cutting, ad-
just t he high speed m ixture setting in
1/16-turn increments asfollows:
• Turn t he high s peed m ixture screw (H)
clockwise until saw has good p ower in
the cut w ith nohesitation. Do not a d-
just b ysound orspeed, but j udge b y
how well the saw performs inthe cut.
• Turn t he high s peed m ixture screw (H)
counterclockwise ifthe saw has
speed, but d ies i nthe cut o rlacks
power inthe cut.
After completing adjustments, check
foracceleration and chain m ovement
atidle. R eset ifnecessary.
Acceleration Check
If the engine dies or hesitates instead of
accelerating, turn the low speed mixture
screw (L) counterclockwise until you
have smooth acceleration with no chain
movement at idle.
,_ WARNING: Perform the following
steps after each use:
• Allow the engine to cool, and secure
the unit before storing or transport-
ing.
• Store chain saw and fuel in a well
ventilated area where fuel vapors
cannot reach sparks or open flames
from water heaters, electric motors or
switches, furnaces, etc.
• Store chain saw with all guards in
place and position chain saw so that
any sharp object cannot accidentally
cause injury.
• Store chain saw well out of the reach
of children.
SEASONAL STORAGE
Prepare your unit for storage at the
end of the season or if it will not be
used for 30 days or more.If your chain
saw is to be stored for a period of time:
• Clean saw thoroughly before stor-
age.
• Store in a clean dry area.
• Lightly oil external metal surfaces
and guide bar.
• Oil the chain and wrap it in heavy pa-
per or cloth.
FUEL SYSTEM
Under FUELING ENGINE in the OPERA-
TION section of this manual, see mes-
sage labeled IMPORTANT regarding
the use of gasohol in your chain saw.
Fuel stabilizer is an acceptable alter-
native in minimizing the formation of
fuel gum deposits during storage. Add
stabilizer to the gasoline in the fuel
tank or fuel storage container. Follow
the mix instructions found on stabilizer
containers. Run engine at least 5 min-
utes after adding stabilizer.
Craftsman 40:1,2-cycle engine oil (air
cooled) is especially blended with fuel
stabilizer. If you do not use this Sears
oil, you can add a fuel stabilizer to your
fuel tank.
ENGINE
• Remove spark plug and pour 1 tea-
spoon of 40:1,2-cycle engine oil (air
cooled) through the spark plug open-
ing. Slowly pull the starter rope 8 to
10 times to distribute oil.
• Replace spark plug with new one of
recommended type and heat range.
• Clean air filter.
• Check entire unit for loose screws,
nuts, and bolts. Replace any dam-
aged, broken, or worn parts.
• At the beginning of the next season,
use only fresh fuel having the proper
gasoline to oil ratio.
OTHER
• Do not store gasoline from one sea-
son to another.
• Replace your gasoline can if it starts
to rust.
