AIR FILTER
CAUTION: Do not clean filter in gasoline or
other flammable solvent to avoid creating a
fire hazard or producing harmful evapora-
tive emissions.
Cleaning the air filter:
A dirty air filter decreases engine perform-
ance and increases fuel consumption and
harmful emissions. Always clean after every
5 hours of operation.

dirt and sawdust from falling into carbure-
tor chamber when cover is removed.

CARBURETOR ADJUSTMENTS
Your carburetor is equipped with limiter
caps. Carburetor adjustment is a compli-
cated task. We recommend that you take
your unit to an Authorized Service Dealer.
Damage will occur if you turn the needles
beyond the limiter stops.
BAR MAINTENANCE
If your saw cuts to one side, has to be forced
through the cut, or has been run with an im-
proper amount of bar lubrication it may be
necessary to service your bar. A worn bar
will damage your chain and make cutting
difficult.
Replace your bar if bent or the inside rails of
the bar are worn.
S
Clean the oil holes after each 5 hours of
operation
S Remove sawdust from bar groove period-
ically with a wire or putty knife.

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 particu-
lar attention to the air intake area, keeping
it free of debris. Use a mild detergent and
sponge to clean the plastic surfaces.
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, furnaces, etc.
S Store in a dry area out of the reach of chil-
dren.
CAUTION: It is important to prevent gum
deposits from forming in essential fuel sys-
tem parts such as the carburetor, fuel filter,
fuel hose, or fuel tank during storage. Alco-
hol 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.
