OIL CHANGE
Operating conditions and severity of service will
determine the intervals between oil changes.
Normal intervals are 4000 operating hours. If
bearings maintain their normal temperature and no
contamination is observed in the oil the intervals
may be prolonged.
If bearing temperature increases, check immediately
for improper lubrication, a faulty bearing or improper
V-ring seat.
