Item Description
Pivot bracket with round magnet
Low-level switch
Control cam
C
Outer orbit of the round magnet

Position of pivot bracket (
LL
activated)
Reservoir full of grease
• Stirring paddle rotates clockwise during
lubrication cycle.
• Pivot bracket of stirring paddle (
B
)
(
† Fig.
) is completely submerged
into grease and grease resistance to
paddle rotation guides bracket with
round magnet (
) inward to orbit (
A
).
• Control cam (
) guides pivot bracket with
magnet and outwards, in direction of
reservoir wall. Since reservoir is full,
grease resistance guides pivot bracket
inward to orbit (
A
) as soon as bracket
passes cam (
).
• Magnet and low–level switch (
)
(
† Fig.
) are not aligned and
switch cannot be activated.
NOTE
Do not use switching parts
to
(
† Fig.
and
Fig.
) with fluid grease
or oil. Use float magnetic switch with
fluid grease or oil.
Reservoir empty of grease
• Control cam (
) (
† Fig.
) guides pivot
bracket with magnet (
) outward. Since
there is no grease resistance, bracket with
magnet (
) stays outward in orbit (
C
).
• Magnet (
) aligns with low–level switch
and activates
LL
indicator on pump
display.
