CARBURETOR ADJUSTMENTS
Your carburetor is equipped with limiter caps. Carburetor adjustment is a complicated 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 improper amount of bar lubrication it may be necessary to service your bar. A worn bar will damage your chain and make cutting difficult.
After each use, ensure ON/STOP switch is in the STOP position, then clean all sawdust from the guide bar and sprocket hole.
To maintain guide bar:
SMove ON/STOP switch to the STOP posi-
tion.
SLoosen and remove chain brake nuts and chain brake. Remove bar and chain from
saw.
SClean the oil holes and bar groove after each 5 hours of operation.
Remove Sawdust From
Guide Bar Groove
Sprocket Hole
Oil Holes
S Add lubricant to sprocket hole after each use.
SBurring of guide bar rails is a normal process
of rail wear. Remove these burrs with a flat file.
SWhen rail top is uneven, use a flat file to re- store square edges and sides.
File Rail Edges

Worn Groove | Correct Groove |
Replace guide bar when the groove is worn, the guide bar is bent or cracked, or when exce-
ssheating or burring of the rails occurs. If re- placement is necessary, use only the guide bar specified for your saw in the repair parts list or on the decal located on the chain saw.

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.
SBefore 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.
SDo 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.
SStore in a dry area out of the reach of chil- dren.
CAUTION: It is important to prevent gum deposits 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.
