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.
A dirty air filter decreases engine perform- ance and increases fuel consumption and harmful emissions. Always clean after every 5 hours of operation.
Cleaning the air filter:
SClean the cover and the area around it to keep dirt and sawdust from falling into the carburetor chamber when the cover is re-
moved.
S Remove the parts as illustrated. S Wash the filter in soap and water. S Replace parts.
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 difficult.
Replace your bar if bent or the inside rails of the bar are worn.
SClean the oil holes after each 5 hours of operation
Remove sawdust from bar groove
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.
SClean 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.
Do not store the unit or fuel in a closedS
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 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.
