STORAGE
WARNING: Stop engineand allow to
cool, and secure the unit before storing or
transporting in a vehicle. Store unit and fuel
in an area where fuel vapors cannot reach
sparks or open flames from water heaters,
electric motors or switches, furnaces, etc.
Storeunitwithallguards inplace.Positionso
that any sharp object cannot accidentally
cause injury to passersby. Store the unit out
of reach of children.

WARNING: Maintain the proper hook
angle according to the manufacturer’s specifi-
cations for the chain you are using. Improper
hook angle will increase the chance of kick-
back which can result in serious injury.

S
Maintain rounded front corner of
depth gauge with a flat file.
S Store in a dry area out of the reach of chil-
dren.
NOTE: The very top of the depth
gauge should be flat with the front
half rounded off with a flat file.
S Ensure the machine is cleaned and that a
complete service is carried out before
long--term storage.
S The guide bar and chain must always be
covered with a scabbard when the machine
is being transported or in storage in order to
prevent accident contact with the sharp
chain. Even a non--moving chain can cause
serious cuts to yourself or persons you
bump into with an exposed chain.
If you require further assistance or are unsure
about performing this procedure, contact your
authorized service dealer.
CARBURETOR ADJUSTMENT
WARNING: The chain will be moving
during most of this procedure. Wear your pro-
tective equipment and observe all safety pre-
cautions. The chain must not move at idle
speed.
The carburetor has been carefully set at the
factory. Adjustments may be necessary if
you notice any of the following conditions:
S Chain moves at idle. See IDLE SPEED--T
adjusting procedure.
S Saw will not idle. See IDLE SPEED--T ad-
justing procedure.
CAUTION: It is important to prevent
gum deposits from forming in essential fuel
system parts such as the carburetor, fuel fil-
ter, fuel hose, or fuel tank during storage. Al-
cohol blended fuels (called gasohol or using
ethanol or methanol) can attract moisture
which leads to fuel mixture separation and
formationofacids duringstorage. Acidic gas
can damage the engine.
Idle Speed--T
Allow engine to idle. If the chain moves, idle

Adjust speed until engine runs without chain
movement (idle too fast) or stalling (idle too
slow). Theidle speedscrew is located inthe
area above the primer bulb and is labeled T.
