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 be- yond 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 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.
SClean the oil holes after each 5 hours of
operation
SRemove sawdust from bar groove peri- odically with a wire or putty knife.
