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.
