A good maintenance program is imperative
for the PTO/Clutch. Read the Stein
PTO/Clutch information supplied in this
manual or read the Twin Disc manual
supplied with the chipper depending on the
engine and clutch supplied on your chipper.
The PTO/clutch requires a maintenance plan
that includes lubrication and adjustment to
get the most service and use from the clutch.
