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.

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.

S Clean the oil holes and bar groove after each 5 hours of operation.
