For the “compressed air brake” version
Machines that are equipped with a compressed air brake have two compressed air reservoirs
(1, 2). The compressed air reservoir (1) for the compressed air brake is on the right-hand
machine side behind the side hood on the frame. The compressed air reservoir (2) for the
knotter cleaning is located on the right-hand machine side above the twine box on the frame.
The both compressed air reservoirs are connected with each other via a pressure line.
For “hydraulic brake” version
Machines that are equipped with a hydraulic brake have a compressed air reservoir (2). The
compressed air reservoir (2) for the knotter cleaning is located on the right-hand machine side
above the twine box on the frame.
4.19 Description of functions of central lubrication system
The central lubrication system is a progressive system. “Progressive” means that all lubrication
points included in the central lubrication system are lubricated one after the other. A progressive
central lubrication system can be monitored easily by a pressure limiting valve because the
lubrication points are lubricated one after the other. If a lubrication point does not take any
grease from the progressive distributor, the progressive distributor is blocked and a pressure of
280 bar (4060 PSI) is built up in the central lubrication system. Grease emerging on the
pressure limiting valve of the pump element indicates a blockage. Error messages are shown
on the display of the terminal.
Design of the central lubrication system
An electrically driven piston pump delivers lubricant to the main progressive distributor. Its task
is to distribute grease to the sub-progressive distributors at the correct ratio. Then, the sub-
progressive distributors pump the grease to the individual lubrication points. The lubrication
duration and the break times are controlled via terminal,
