NOTE
The white reflector in the sight gauge must be posi-
tioned horizontally to provide proper drainage.
Under normal conditions, drain the pedestal once
each year and refill with approximately 14 ounces
(414 ml) of clean oil. Change the oil more fre-
quently if the pump is operated continuously or in-
stalled 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.
Seal Assembly
Fill the grease cup (14) through the grease fitting
with No. 2 lithium base grease until grease es-
capes from the relief hole. Turn the grease cup arm
counterclockwise until it is at the top of the stem;
this will release the spring to apply grease to the
seal (see Figure 6).

have seated in.
