Monitoring of Function
Monitoring of Function
The eccentric shaft (item 9, Fig. 4), located at the bottom of
the pump housing cover, serves for checking the function. If it
turns clockwise, the pump element is operating correctly.

NOTE
Before switching on the hydraulic unit,
check whether there is sufficient lubricant
in the cartridge. If necessary, replace the
cartridge (see chapter „Maintenance“,
page 10).
IMPORTANT
The lubrication pump must be protected
with a pressure relief valve (item 7,
Fig. 1, page 7).
NOTE
If the lower outlet connection is used for
lubricant delivery, the pressure relief valve
must be fitted to the upper outlet connec-
tion.

Pump Element

Pump Element
During the operation the piston (item 4, Fig. 5) sucks in lubri-
cant from the cartridge via the suction bore hole (item 2, Fig.
5) and delivers it to the connected lubrication point through
the bore hole (item 1, Fig. 5). An integrated check valve pre-
vents the lubricant from returning to the cartridge.

Pressure Relief Valve

Pressure relief valve (cartridge)
The pressure relief valve
limits the pressure build-up in the system,
opens when a pressure of 120 bar is reached.

NOTE
If lubricant is expelled at the pressure
relief valve, this indicates that there is a
blockage to, or at the lubrication point.
