Mini Round Baler SRB - 870
Adjustments
Roller Chain:
Roller chains will stretch during normal usage, especially during initial use of the baler. This is normal for any
type of roller chain and is to be expected. Performing regular maintenance will extend the life of the chains
and sprockets. Loose chain will cause premature wear of sprockets and will affect the performance of the bal-
er. Check tension of chains and tighten when necessary.
The main drive chain (LH cover) is adjusted by tightening or loosening the tensioner springs and by adjusting
the tension plate. The manufacturer recommends Spring
“ A ” to be set at 1 - 7/16” and Spring “ B ” set at 1 - 1/2”
for optimal performance. The tensioner plate should deflect the joint chain by approximately 1/8”. Adjust as
needed.
Adjust the hydraulic power pack drive chain by loosening the power pack hardware and moving the position of
the hydraulic power pack. Proper chain deflection for the hydraulic power pack chain is approximately
3/16”.
