CHAIN BRAKE
The CHAIN BRAKE is a device designed to
stop the chain if kickback occurs. The chain
brake activates automatically in the event of
kickback. The chain brake activates manu-
ally if the front hand guard is pushed forward.
The chain brake is disengaged by pulling the
front hand guard back toward the front han-
dle as far as possible.
CHAIN TENSION
It is normal for a new chain to stretch during
first 15 minutes of operation. You should check
your chain tension each time before you start
the chain saw. See CHAIN TENSION in the
ASSEMBLY section.
WARNING: If the saw is operated
with a loose chain, the chain could jump off
the guide bar and result in serious injury to
the operator and/or damage the chain mak-
ing it unusable.

tion of this manual before you begin. If you do

FUELING ENGINE
WARNING: Remove fuel cap slow-

HELPFUL TIP
To obtain the correct oil mix
ratio, pour 3.2 ounces of
2--cycle synthetic oil into
one gallon of fresh gas.
This engine is certified to operate on unleaded
gasoline. Before operation, gasoline must be
mixed with a good quality synthetic 2-cycle
air-cooled engine oil designed to be mixed at a
ratio of 40:1. Poulan/WEED EATER brand
synthetic oil is recommended. Mix gasoline
and oil at a ratio of 40:1. A 40:1 ratio is obtained
by mixing 3.2 fluid ounces of oil with 1 gallon of
unleaded gasoline. Included with this saw is a
3.2 ounce container of oil. Pour the entire
contents of this container into 1 gallon of
gasoline to achieve the proper fuel mixture. DO
NOT USE automotive oil or boat oil. These oils
will cause engine damage. When mixing fuel,
follow instructions printed on container. Once
oil is added to gasoline, shake container
momentarily to assure that the fuel is
thoroughly mixed. Always read and follow the
safety rules relating to fuel before fueling your
unit.
CAUTION: Never use straight gasoline in
your unit. This will cause permanent engine
damage and void the limited warranty.
FUEL REQUIREMENTS
This engine requires the use of minimum 87
octane [R+M]/2 clean gasoline.
