Drive Sprockets

Your drive sprocket, the third member of the cutting

team, deserves regular attention and maintenance just

like your bar and chain. A misused sprocket will cause

patterns of chain wear which can damage the guide bar

and reduce the life of all three components. A damaged

sprocket cannot be repaired, it can only be inspected

and replaced. Here are the things to look for, and the

steps to take.

OREGON

SPROCKET MAINTENANCE

ATTENTION: Oregon

urges dealers, chainsaw users,

and anyone who services sprockets to become familiar

with proper sprocket-maintenance techniques and the

possible dangers which can result if sprockets are not

properly maintained.

CONTINUED…

Always turn off your saw’s engine before handling the

chain, guide bar or sprocket. Failure to do so can result

in severe injury.
