10. Repairs
Servicing may only be carried out by the manufacturer or personnel trained by the
manufacturer and by authorised LUKAS dealers.
Only LUKAS spare parts may be used to replace all components (see spare parts list) since
special tools, assembly advice, safety aspects, inspections might have to complied with (see
also chapter “Maintenance and Service”).
During assembly, ensure the complete cleanliness of all components, since dirt can
damage the rescue equipment!
WARNING / CAUTION!
Protective clothes must be worn when repairs are being carried out, since parts
of the units can also be pressurised in an idle state.
REMARK:
Please always register your tool on the LUKAS website. Only then are you
entitled to the extended guarantee.
REMARK:
Before you use couplings from a different company, you must contact LUKAS or
an authorised dealer.
REMARK when using the quick-disconnect-coupling system:
Overpressure protection of the rescue equipment
(model with yellow coupling nipple on the return hose)
If the equipment’s short hoses are not connected to a unit, temperature
increases can inadvertently cause pressure to build up in the equipment. Hence,
the return hose of the equipment is equipped with a safety coupling (quick-
disconnect coupling male, yellow). Unwanted overpressure (approx. 1.5 Mpa) is
automatically released via this nipple: hydraulic fl uid leaks.
Should an hydraulic fl uid leak 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 can react in the valve of the rescue equipment.
Hydraulic fl uid leaks 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!
Because LUKAS rescue equipments are appropriate for highest achievements,
only components may be exchanged, which are specifi ed in the spare parts list
of the appropriate equipment.
Further components of the equipment may only be exchanged, when:
- you have participated on a appropriate LUKAS service training.
- you have the explicit permission of the LUKAS Service department (After inquiry,
examination for the distribution of permission. Examination in each individual
case necessarily!)
