13 Repairs
13.1 General
Servicing must be carried out only by the device manufacturer or by personnel trained by the
manufacturer or the authorised LUKAS dealers.
For replacement on all components, use only genuine LUKAS spare parts as specified in the spare
parts list, as here possibly required special tools, mounting information, safety aspects, testing
must absolutely be taken into account. See Section 4.
Protection of the device against hydraulic overload
(only for DIN version with yellow quick coupler on the blue return hose)
If the short hoses of the tool are not connected with the power pack, pressure can be built up
unintentionally in the cylinder due to temperature increase. Therefore, the return hose (0,5 m / blue)
of the tool is equipped with a safety coupling (quick connect plug, colour yellow). Unin-tentional
overpressure (approx. 1.5 MPa) is released through this plug: oil comes out.
Should the tool have been equipped with couplers of different brand which do not have this safety
function, overpressure would be released through another safety valve (adjusted to approx. 30
MPa) included with the control valve block. In this case oil spill would be observed in the star grip
area. As soon as sufficient pressure is released the valve becomes tight again. Should further
constant leakage ocur, please have the tool inspected by LUKAS personnel.
On repair, protective clothing is mandatory (see Section 1), as the spreaders can be pressurized
also in unoperated state.
13.2 Preventive maintenance
13.2.1 Maintenance advice
To protect the device against external corrosion clean its surface from time to time and slightly
grease it with oil.
13.2.2 Function and load test
If there is any doubt as to the safety and reliability of the equpiment, carry out an additional function
and load test. For this purpose, LUKAS offers a test kit as appropriate equipment.
