BAR MAINTENANCE
If your saw cuts to one side, has to be forced
through the cut, or been run with an improper
amount of bar lubrication it may be neces-
sary to service your bar. A worn bar will dam-
age your chain and make cutting
difficult.
Replace your bar if bent or the inside rails of
the bar are worn.
S

operation

CARBURETOR ADJUSTMENTS
Carburetor adjustment is critical and if done
improperly can permanently damage your
unit. We recommend you contact an Autho-
rized Service Dealer for adjustments.
IDLE SPEED ADJUSTMENT:
Turn the Idle
Speed Screw clockwise until it stops. Now
turn the screw counterclockwise 4-1/2 turns.
This should allow the engine to run without
the chain turning. If the chain moves at idle
speed, do not use your unit. Contact an Au-
thorized Service Dealer. Idle speed is cor-
rect when engine runs without stalling and
chain does not turn.
MIXTURE ADJUSTMENTS:
If your carbu-
retor includes limiter caps (Plastic caps on
the mixture screws) , do not force the screws
beyond the stops of the limiter caps or dam-
age will occur. Do not remove these caps.
Small adjustments will affect your unit. Do
not adjust more than 1/16th turn without
checking performance.
CHAIN SHARPENING
Chain sharpening is a complicated task that
requires special tools. We recommended
you refer chain sharpening to a professional
chain sharpener. If you choose to perform
your own chain sharpening, call our toll-free
helpline and order a free chain sharpening
guide. (See the back page of this manual for
the toll-free phone number.)
IGNITION TIMING
Ignition timing is fixed and nonadjustable.
SPARK PLUG
Replace the spark plug yearly using a Cham-
pion RCJ7Y. Gap to .025”.
STORAGE
WARNING:
Stop engine and 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.
Store unit with all guards in place. Position so
that any sharp object cannot accidentally
cause injury to passersby. Store the unit out
of reach of children.
S
Before storing, drain all fuel from the
unit. Start engine and allow to run until it
stops.
S
Clean the unit before storing. Pay partic-
ular attention to the air intake area, keep-
ing it free of debris. Use a mild detergent
and sponge to clean the plastic sur-
faces.
S
Do not store the unit or fuel in a closed
area where fuel vapors can reach
sparks or an open flame from hot water
heaters, electric motors or switches, fur-
naces, etc.
S
Store in a dry area out of the reach of
children.
CAUTION:
It is important to prevent gum de-
posits from forming in essential fuel system
parts such as the carburetor, fuel filter, fuel
hose, or fuel tank during storage. Alcohol
blended fuels (called gasohol or using
ethanol or methanol) can attract moisture
which leads to fuel mixture separation and
formation of acids during storage. Acidic gas
can damage the engine.
