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:

S

Move ON/STOP switch to the STOP posi-

tion.
