line or other flammable solvent to avoid

ance and increases fuel consumption and
harmful emissions. Always clean after every
5 hours of operation.

keep dirt and sawdust from falling into t he
carburetor chamber when the cover is re-
moved.

re-installing.
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.
