The grease lubrication system is a progressive system. It operates all types of grease of NLGI kl. 2 type. See
recommended lubricants in section 8.6.3 "Greasing".
A progressive lubrication system, means that all the bearings are lubricated one by one. This progressive sys-
tem makes the lubrication system easily monitored trough a high pressure relief valve (nr.9, section 8.1.3
"Beka max grease lubrication system"). If a lubrication line to a bearing is clogged, the pressure will
increase (280 bar) and visible grease appears on the relief valve.
Please check the pressure relief valve on a regular basis. If visual grease is present, a line or a distributor is
clogged. Another malfunction could be that a line is broken, but then there’s no visual grease on the relief
valve.
NOTE: New machine: In the first weeks of operation, the system must be checked frequently. Check that there’s
a visual grease collar on all lubrication points. This indicates all the bearings are being lubricated. Keep track of
the grease consumption. Be aware if the daily grease consumption changes. This might indicate that some-
thing is wrong.
