The compactor is equipped with a fully automac lubricaon system. It lubricates the sleeve bearings
(grease) and the chains (oil).

A single piston pump driven by the hydraulic pressure, supply oil to the chains through brushes which is
mounted on strategic locaons. Each me the chamber tailgate opens, the piston is acvated and supply a
x amount of oil to chains.

An electrical motor (connuous drive) runs an eccentric. The eccentric drive two single working pistons
which press a x amount of grease through a pressure relief valve, and further on to a main distributor. The
main distributor supply then grease to sub-distributors, which deliver the correct amount of grease to each
bearing. Not the same amount of grease to all bearings!
The grease lubricaon system is a progressive system. It operate all types of grease of NLGI kl. 2 type. See
recommended lubricants in chapter 5.2.6. A progressive lubricaon system, means that all the bearings is
lubricated one by one. This progressive system make the lubricaon system easily monitored trough a high
pressure relief valve. (nr.9, gure 1) If a lubricaon 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
base. If visual grease is present, a line or a distributor is clogged. An another malfuncon could be that a line
is broken, but then there’s no visual grease on the relief valve.
