For proper operation and to prevent downtime and
repair, keep drive chains properly adjusted and lubri-
cated. Regularly check drive chains for excess slack
and wear. Adjust idlers to remove any excess slack
from chains.
NOTE: Be sure chain is installed with chain con-
nector link retainer towards the centerline and
the clip opening (split end) is facing opposite
way of chain travel.
