Connection to Hydraulic Power Sources
The breaker can be connected to various hydraulic power sources, such as excava-
tors, trucks, loaders, tractors etc., and of course HYCON powerpacks, the design of
which ensures your new HYCON breaker the absolute best working conditions.
It is important that the breaker is not subjected to an oil flow and a working pressure
beyond its design capability. Please refer to the ID-tag on the breaker in case of
doubt. Check the oil flow and the working pressure by means of test equipment. The
test equipment should comprise a pressure gauge, a flow meter and a valve for
adjustment of the pressure.
Make sure that:
•
the oil flow is not too high
•
the working pressure is not too high
•
the return pressure is not too high
•
the pressure relief valve is not set higher than 160 bar
•
the internal diameter of the hoses is sufficient (min. ½”)
•
all couplings are clean
•
the power source is equipped with an oil filter of min. 25 Micron
Hoses with too small internal diameter and/or defect couplings cause the breaker to
work with incorrect working pressure. Your dealer can help you check this.
If the output of the power source is too high:
•
the power source must be adjusted to correct output
•
or you can choose to mount a HYCON oil flow divider to protect the breaker
against overload
•
or you can choose one of our HYCON powerpacks. Your dealer can guide you
in choosing the right powerpack.
In case of doubt, please contact your dealer or HYCON A/S.

NB. At service/repair it is important to mount the hoses correctly. The feed line from the power source
must be mounted at “P” and the return line at “T”. “P” and “T” are marked on the valve housing.
