trigger. This feature prevents you from acci-
dentally squeezing the trigger.
CHOKE/ FAST I D LE LEVER
The choke and fast idle are set by pulling the
CHOKE/F AST IDLE L EVER out to the ful l e x-
tent for cold starting or after refueling. The
choke provides additional fuel to the engine
during cold starting.
PRIMER BULB
The PRIMER BULB circulates fuel to the car-
buretor to provide quicker starting.
CHAIN BRAKE
The chain brake is a device designed to stop
the cha in if kickba ck occu rs. The cha in brake
activates automatically in the event of kick-
back. The chain brake activates manually ifthe
front hand guard is pushed forward. The chain
brake is disengaged by pulling the front hand
guard back toward the front handle as far as
possible.
CHAIN TENSION
It is normal for anew chain to stretch during the
first 15 minutes of operation. Y ou should check
your chain tension each time before you start
the chain saw. See CHAIN TENSION under
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.
BEFORE STARTING ENGINE
WARNING: Muffler is very hot dur-
ing andafter use. Do not touch the muffler or
allow combustible material such as dry
grass or fuel to do so.
WARNING: Be sure to read the f uel
handling information in the safety rules sec-
tionof this manu al befor eyou begin.If you do
not understand the fuel handling information
do not attempt to fuel your unit. Seek help
from someone that does understand the in-
formation or call the customer assistance
help line at 1-800-554-6723.
FUELING ENGINE
WARNING: Remove fuel cap slow-
ly when refueling.
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 un-
leaded 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. A 40:1 ratio is ob-
tainedby mixing 3. 2fluidounces (95 ml) ofoil
with 1 gallon (4 liters) of unleaded gasoline.
Pour the entire contents of the 3.2 ounce (95
ml) container of oil into 1 gallon (4 liters) of
gasoline to achieve the proper fuel m ixture.
DO NOT USE automotive or m arine oil.
These oils will cause engine damage. When
mixing fuel follow the instructions printed on
the 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 fuelbe-
fore fueling your unit.
CAUTION : Ne ve r use strai g h t gaso l i n e i n
your unit. This will cause permanent engine
damage and void the limited warranty.
FUEL REQUIREMENTS
This engine requires the use of minimum 8 7
octane [R+M]/2 clean gasoline.
IMPORTANT
Use of alcohol blended fuels (called gasohol or
using ethanol or methanol) can cause major
engine performance and durability problems.
WARNING: Alternative fuels (not
gasoline) such as E--15 (15% alcohol), E--20
(20% alcohol), E--85 (85% alcohol) are NOT
classified as gasoline and are NOT approved
for use in 2--stroke gasoline engines. Use ofal-
ternative fuels will cause problems such as: im-
proper clutch engagements, overheating, va-
por lock, power loss, lubrication deficiency,
deterioration of fuel lines, gaskets and internal
carburetor components, etc. Alternative fuels
cause high moisture absorption into the fuel/oil
mixture leading to oil and fuel separation.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubri-
cation. Lubrication is provided by the auto-
matic oiler system when the oil tank is kept
filled. Lack of oil will quickly ruin the bar and
chain. Too little oil will cause overheating
shown by smoke coming from t hechain and/
or discoloration of the bar.
In freezing weather oil will thicken, making it
necessary to thin bar and chain oil with a
small amount (5 to 10%) of #1 Diesel Fuel or
kerosene. Bar and chain oil must be fr ee
flowingfor the oil systemto pump enough oil
for adequate lubrication.
If bar and chain oil is not available, use a
good grade SAE 30 oil.
S Never use waste oilfor bar and chainlubri-
cation.
S Always stop the engine before removing
the oil cap.
CHAIN BRAKE
Ensure chain brake is disengaged by pulling
the front hand guard back toward the front han-
dle as f ar as possible. The chain brake must be
disengaged before cutting with the saw .
WARNING: The chain must not
move when the engine runs at idle speed. If
the chain moves at idle speed refer t o CAR-
BURETOR ADJUSTMENT within this
manual. Avoid contact with the muffler. A hot
muffler can cause serious burns.
