CHAIN BRAKE
The

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.

W ARNING:
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
W ARNING:
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 oi l tank when you
fill the fuel tank (Capaci ty = 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 C raftsman bar oil
is not available, you may use a good
grade SAE 30 oil until you are able to
obtain Craftsman brand. The oi l 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 fil l the fuel tank.
FUELING ENGINE
W ARNING:
Remove fuel cap
slowly when refueling.
This engine is cert ified to o perate on un-
leaded gasoline. Before operation, gaso-
line must be mix ed wit h a good qua lity
synthetic 2-cycle air-cooled engine oil.
W e r ecommend C raft sman brand syn-
thetic oil. Mix gasoline and oil at a ratio
of 40: 1. A 40:1 r atio is obtained by mix-
ing 3.2 ounces ( 95 m l) of oil with 1 gal-
lon (4 litres) of unleaded gasoline. I n-
cluded with t his saw is a 3.2 ounce (95
ml) container of C raft sman brand oil.
Pour t he entire contents of this container
into 1 gallon (4 litre s ) of gasolin e t o
achieve the pr oper fuel mixture.
DO NOT
USE
automotive oil or m arine oil. These
oils will cause engine damage. W hen
mixing f uel follow the instructions printed
on t he container. Once oil is added t o
the gasoline, shake c ontainer momen-
tarily to assure that the fuel is thoroughly
mixed. Always read and follow the s afe-
ty r ules relating to f uel bef ore f ueling
your unit.
IMPORTANT
Experience i ndicates 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.
