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.

Clean the cover and the area around it

to keep dirt and sawdust from falling

into the carburetor chamber when the

cover is removed.

Remove the parts as illustrated below.

Wash the filter in soap and water.

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 been run with an improp-

er amount of bar lubrication it may be nec-

essary to service your bar. A worn bar will

damage your chain and make cutting diffi-

cult.

Replace your bar if bent or the inside rails of

the bar are worn.

Clean the oil holes after each 5 hours of

operation

Remove sawdust from bar groove peri-

odically 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.

Before storing, drain all fuel from the

unit. Start engine and allow to run until it

stops.

Clean the unit before storing. Pay par-

ticular attention to the air intake area,

keeping it free of debris. Use a mild de-

tergent and sponge to clean the plastic

surfaces.

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.

Store in a dry area out of the reach of

children.

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.
