Lubricate the sealed bearings with grease cups
For models with grease-lubricated bearings, the spring-operated automatic grease cups are designed to
maintain constant lubrication of the intermediate pump bearings that are fixed to the vertical pump
housing. The center stem protrudes out of the housing when the cup is full and gradually moves down
into the housing as the grease is used. After the wing nut is threaded against the stem zerk fitting and the
bottom of the wing nut rests on the cap of the grease cup, then the grease reservoir is empty and you must
refill it.
