INSPECTION OF PTO BELT
Periodically checking the PTO belt (A) of this power
unit can prevent sudden failure by fi nding problems
before they cause the belt to break. It is recom-
mended to inspect the PTO belt every 50 hours of
operation, or if a problem is suspected. There may
be a PTO belt problem if there is a squealing or
chattering sound, or the smell of a slipping belt.
