dicated. Check the constant level oiler regularly
and keep it full of oil. When lubrication is required,
flip the transparent constant level oiler cup open
and fill it with SAE No. 30 non‐detergent
oil.
Under normal conditions, drain the bearing hous
ing once each year and refill with clean oil. Change
the oil more frequently if the pump is operated con
tinuously or installed in an environment with rapid
temperature change.
Monitor the condition of the bearing lubri
cant regularly for evidence of rust or mois

cold temperatures are common.
For cold weather operation, consult the factory or a
lubricant supplier for the recommended grade of
oil.
