2. Grease Container Replacement
When the grease container becomes empty, follow the
procedure below to replace it.
IMPORTANT: When replacing the grease container, be sure
that no sand or debris sticks to suction tube
(5) or to follower plate (3). If foreign matter,
such as sand, gets into grease, damage to
the pump and to parts being lubricated will
result. If follower plate (3) is not correctly po-
sitioned inside the container, the pump may
not suck grease, even with grease remaining
in the container. Reposition the plate cor-
rectly if this happens.
(1) Loosen wing nuts (2) located on pail cover (7).
Remove the pump assembly (pump (1), pail cover (7),
and suction tube (5)) and follower plate (3) from the
empty grease container (4).
(2) Remove the cover from the new grease container.
(3) Apply grease to the back of follower plate (3) to fill con-
caved sections; this will prevent air from mixing into the
grease contents.
(4) Place follower plate (3) flat on the grease contents in
the container. Using both hands, press follower plate (3)
down while moving both hands back and forth along
the periphery of the container inside, as illustrated, until
grease comes out of seal packing (6) hole.
IMPORTANT: Be careful not to damage seal packing (6) by
the end of suction tube (5) when inserting it.
(5) Slowly insert suction tube (5) (the pump assembly) into
the grease contents via the seal packing hole.
(6) Be sure that pail cover (7) correctly settles on the con-
tainer. Equally tighten each wing nut (2) to pail cover
(7) to securely attach the pump assembly onto the con-
tainer.
(7) After replacing the grease container (4), secure the lu-
bricator unit with bracket.
