SECTION 7
LUBRICANTS
The tank pump can operate with standard grease
types available on the market up to class NLGI 2.
Class NLGI indicates exclusively the static density
of grease, but not the dynamic behaviour of grease
while pumped. The characteristics of fluidity of
grease of same class NLGI may differ remarkably
between them.

WARNING
The Manufacturer is not liable for damages to the
centralized lubrication system, caused by chemical
or biological alterations of the lubricant used, or by
grease not allowed or to be used only in a limited
way.
During the handling of grease care for maximum
cleanliness. The dirt inside of grease remains sus-
pended and cannot settle. This creates problems to
the system and as a consequence also damages to
the articulation points.
Lubricants with solid residuals higher than 3% can-
not be used for the centralized lubrication system.
TANK PUMP
The tank pump (1) is secured behind the cab and is
accessible through the left side door. The lubrication
processes are handled according to the machine
service hours. When the ignition key is set to "I", the
centralized lubrication system activates and lamp
(2) lights up.
A lubrication cycle consists of a down-time and a
work time. The lubrication system is repeated con-
tinuously after machine start. During the working
time, the tank pump delivers lubricant to the different
points to be lubricated, flowing through the distribu-
tion manifolds.
The down-time defines the frequency of the lubrica-
tion periods inside of the operation time. The work-
ing time defines the quantity of lubricant delivered. A
longer working time means an higher quantity of
lubricant, a shorter working time means a lower
quantity of lubricant. When the machine is shut off,
the down-times and working times already passed
are summarized and memorized on an unlimited
time. When the ignition cylinder is activated again,
the control restarts from the point of disconnection.
