Under normal conditions, change the oil each
5000 hours or once each year, more frequently if
the pump is operated continuously or installed in
an environment with rapid temperature change.
Monitor the condition of the bearing lubri-
cant regularly for evidence of rust or mois-
ture condensation. This is especially im-
portant in areas where variable hot and
cold temperatures are common.
For cold weather operation, consult the factory or a
lubricant supplier for the recommended grade of
oil.
