9.2.1  Care instructions

The exterior of the equipment is to be cleaned from time to time in order to protect it from 

external corrosion. Oil is to be applied to the metallic surfaces.

9.2.2  Function and load test

If there is any doubt regarding the safety or reliability of the equipment, a function and load 

test must also be performed.

9. Repairs

  9.1  General information

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), as 

special tools and compliance with assembly instructions, safety aspects and inspections are 

required (see also chapter “Maintenance and Servicing”).

During assembly, ensure that all components are particularly clean, since dirt can 

damage the rescue equipment!

WARNING / CAUTION / ATTENTION!

Protective clothes must be worn when repairs are being carried out, as the 

devices may also be pressurised when not in operation.

NOTE:

Always register your device on the LUKAS Hydraulik GmbH website. This is the 

only way to guarantee your extended warranty cover.

NOTE:

You  should  always  contact  LUKAS  or  an  authorised  dealer  before  using 

couplings from another manufacturer.

ATTENTION!

Because LUKAS rescue equipments are appropriate for highest achievements, 

only components may be exchanged, which are specified in the spare parts list 

of the appropriate equipment.

Other components in the device may only be replaced if:

-  You have participated in an appropriate LUKAS service training course.

-  You have the explicit permission of LUKAS Customer Service (on request, 

verification that permission may be granted. To be checked in each individual 

case!)

  9.2  Preventative service

A functional test must be carried out after repairs:

Extend the device 2-3 times in the unloaded state so that any air present can escape from 

the system.
