About these Assembly
instructions
These Assembly instructions describe how to
retrot a CP-Lube automatic lubrication system to
your hydraulic breaker.
You are only allowed to

with automatic lubrication system CP-Lube. You
are not allowed to
retrot any other machines with
the CP-Lube automatic lubrication system than
those mentioned above.
The Assembly instructions complement your
hydraulic breaker's Safety and operating
instructions.
Follow all instructions in the Assembly instructions
and in the Safety and operating instructions.
Store these Assembly instructions together with
the Safety and operating instructions in the
document compartment of the carrier cab.
All symbols, signal words, and designation of the
text used in the Assembly instructions are the
same as in the Safety and operating instructions.

Function
CP-Lube is a self-contained pump unit for
delivering high-viscosity pastes such as those used
for preference on hydraulic breakers.
The pump is connected to the percussion unit by
two hoses, one from port »PL« of the hydraulic
breaker to the pump inlet, the other as a grease
line from the pump outlet to port »L« on the
hydraulic breaker.
Each time the hydraulic breaker is switched on, the
system pressure from the excavator acts on a feed
piston in the pump unit which delivers grease
from the cartridge to the lower breaker part
through the grease line. When the hydraulic
breaker is switched off, the system is depressurised
and the feed piston is pushed by a spring back to
its starting position. The atmospheric pressure
acting on the cartridge from outside causes more
grease to be fed into the pump chamber, and the
CP-Lube is once again ready for use.
The amount of grease delivered to the lower
breaker part depends on how often the hydraulic
breaker is switched on and off and on the setting
of the metering screw on the pump unit.
