Outline of the system
This system automatically executes the all of the relevant ac-
tions for greasing. When the starting switch is in ON position,
the grease pump distributes the measured amount of grease at
regular time intervals that have been set beforehand, to all of
the greasing points which are connected to this system.
The selected lubrication interval is displayed within 60 seconds
after the starting switch is turned to ON position with the flash-
ing green lamp (4) on the automatic lubricating system monitor
(2).
(A): Lubrication interval for the light duty work
(B): Lubrication interval for the normal operation
(C): Lubrication interval for the heavy-duty work
How to change the lubrication interval on the auto-greasing monitor
1) Check that the starting switch is in ON position.
2) Press the lubricating mode selector switch (3) on the auto-
matic lubricating system monitor (2) to select the appropriate
interval.
