Grease Container Replacement
When the grease container becomes empty, follow the
procedure below to replace it.
IMPORTANT: When replacing grease container (4),
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 pump (1) and to parts
being lubricated will result. If follower
plate (3) is not correctly positioned inside
the container, pump (1) may not suck
grease, even with grease remaining in the
container. Reposition the plate correctly if
this happens.
1. Loosen wing bolts (2) located on pail cover (7).
Remove the pump assembly (pump (1), pail cover (7),
and suction tube (5)) and follower plate (3) from empty
grease container (4).
2. Remove the cover from new grease container (4).
3. Apply grease to the back of follower plate (3) to fill
concaved 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 seal packing (6) hole.
6. Be sure that pail cover (7) correctly settles on the
container. Equally tighten each wing bolts (2) to pail
cover (7) to securely attach the pump assembly onto the
container.
7. After replacing grease container (4), surely insert
bracket (8) installed pail cover (7) into bracket (9) of the
lubricator box.
