NOTE when using the quick-disconnect coupling system:
Over-pressuresafetydeviceoftherecyclingunit
(modelwithyellowcouplingnippleonthereturnhose)
Pressure can build up in the device as a result of temperature rises if the device's
short hoses are not connected to a power pack. Hence, the return hose of the
equipment is equipped with a safety coupling (quick-disconnect coupling male,
yellow). Undesired overpressure (approx. 1.5 MPa) is automatically reduced via
this male coupling: hydraulic uid leaks out.
Should hydraulic uid leaks on the coupling male be more frequent, please
contact your dealer or LUKAS itself.
If couplings from a different company are used which do not have this function,
the overpressure protection in the valve of the rescue equipment may respond.
Hydraulic uid leaks out in the area of the star grip. Following the reduction in
pressure, the valve is once again tight.
Should the valve leak permanently, please immediately contact your dealer or
LUKAS itself.
CAUTION!
When cleaning the equipment, take care not to use any cleaning agent that has
a pH value outside the range 5 - 8!
