ON/STOP SWITCH
The
ON/STOP SWITCH is used to stop
the engine.
THROTTLE TRIGGER
The
THROTTLE TRIGGER controls en-
gine speed.
THROTTLE LOCK--OUT
The
THROTTLE LOCK--OUT must be
pressed before you can squeeze the
throttle trigger. This feature prevents
you from accidentally squeezing the
trigger.
CHOKE/FAST IDLE LEVER
The choke and fast idle are set by pull-
ing the
CHOKE/FAST IDLE LEVER out
fully for cold or after refueling. The
choke provides additional fuel to the
engine during cold starting.
CHAIN BRAKE
The
CHAIN BRAKE is a device de-
signed to stop the chain if kickback oc-
curs. The chain brake activates auto-
matically in the event of kickback. The
chain brake activates manually if the
front hand guard is pushed forward.
The chain brake is disengaged by pull-
ing the front hand guard back toward
the front handle as far as possible.
CHAIN TENSION
It is normal for a new chain to stretch
during first 30 minutes of operation. You
should check your chain tension fre-
quently. See
CHAIN TENSION under the
SERVICE AND ADJUSTMENTS section.
WARNING: Muffler is very hot
during and after use. Do not touch the
muffler or allow combustible material
such as dry grass or fuel to do so.
BEFORE STARTING ENGINE
WARNING: Be sure to read the
fuel handling information in the safety
rules section of this manual before you
begin. If you do not understand the
fuel handling information do not at-
tempt to fuel your unit. Seek help from
someone that does understand the in-
formation or contact your Sears Ser-
vice Centre.
GUIDE BAR AND CHAIN OIL
The chain oiler provides continuous
lubrication to the chain and guide bar.
Be sure to fill the bar oil tank when you
fill the fuel tank (Capacity = 6.8 fl. oz.).
Lack of oil will quickly ruin the bar and
chain. Too little oil will cause overheat-
ing shown by smoke coming from the
chain and/or discoloration of the bar.
For maximum guide bar and chain life,
we recommend you use Craftsman
chain saw bar oil. If Craftsman bar oil
is not available, you may use a good
grade SAE 30 oil until you are able to
obtain Craftsman brand. The oil output
is automatically metered during opera-
tion. Your saw will use approximately
one tank of bar oil for every tank of fuel
mix. Always fill the bar oil tank when
you fill the fuel tank.
FUELING ENGINE
WARNING: Remove fuel cap
slowly when refueling.
This engine is certified to operate on un-
leaded gasoline. Before operation, gaso-
line must be mixed with a good quality
synthetic 2-cycle air-cooled engine oil.
We recommend Craftsman brand syn-
thetic oil. Mix gasoline and oil at a ratio
of 40:1. A 40:1 ratio is obtained by mix-
ing 3.2 ounces (95 ml) of oil with 1 gal-
lon (4 litres) of unleaded gasoline. In-
cluded with this saw is a 3.2 ounce (95
ml) container of Craftsman brand oil.
Pour the entire contents of this container
into 1 gallon (4 litres) of gasoline to
achieve the proper fuel mixture.
DO NOT
USE automotive oil or marine oil. These
oils will cause engine damage. When
mixing fuel follow the instructions printed
on the container. Once oil is added to
the gasoline, shake container momen-
tarily to assure that the fuel is thoroughly
mixed. Always read and follow the safe-
ty rules relating to fuel before fueling
your unit.
IMPORTANT
Experience indicates that alcohol
blended fuels (called gasohol or using
ethanol or methanol) can attract mois-
ture which leads to separation and
formation of acids during storage.
Acidic gas can damage the fuel sys-
tem of an engine while in storage.
To avoid engine problems, the fuel
system should be emptied before stor-
age for 30 days or longer. Drain the
gas tank, start the engine and let it run
until the fuel lines and carburetor are
empty. Use fresh fuel next season.

al information.
