NOTE:
When installing a new grease cup, lubricate
the cup as indicated on the installation tag
furnished with the grease cup.

The intermediate was fully lubricated when
shipped from the factory. Check the oil level regu-
larly through the sight gauge (57) and maintain it at
the middle of the gauge. When lubrication is re-
quired, add SAE No. 30 non-detergent oil through
the hole for the air vent (18). Do not over-lubricate.
Over-lubrication can cause the bearings to over-
heat, resulting in premature bearing failure.
Under normal conditions, drain the intermediate
once each year and refill with clean oil. Change the
oil more frequently if the pump is operated continu-
ously or installed in an environment with rapid tem-
perature 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.
