3.11 Working under loads is not allowed if they are only lifted by hydraulic cylinders. If the work
is indispensable sufficient mechanical supports are needed additionally.
3.12 Make sure that hoses are not mechanically stressed (pulling, bending etc.).
3.13 When working in the vicinity of live components and cables, it must be ensured that
precautions are taken to avoid current conductions or high-voltage flashing over to the motor
pump.
3.14 During use of cylinder unit, the creation of electrostatic charges which could result in sparking
must be prevented.
3.15 When mounting the cylinders the power unit should always be placed in such a way that its
function and safety will not be impaired by strong external temperature influences.
4 Instructions for maintenance and service
4.1 For the execution of maintenance and service work, tools and workshop equipment adapted to
the task on hand are absolutely indispensable.
Work on the hydraulic system must be carried out only by personnel having special knowledge and
experience with hydraulic equipment.
4.2 Before putting into operation clean the machine, especially connections and threaded unions,
of any traces of oil, fuel or preservatives before carrying out maintenance/repair. Never use
aggressive detergents. Use lint-free cleaning rags and pay attention that the components are
meticulously clean during reassembling after repair.
4.3 During dismantling of machines it is necessary to collect the outrunning hydraulic liquids
completely, so that they cannot reach the ground. They have to be disposed properly according to
the instructions.
4.4 Always tighten any screwed and thread connections that have been loosened during mainte-
nance and repair. Observe the stipulated torques.
4.5 Aggressive material (acid, lye, solvent, vapour) can damage the machine. It is necessary to
clean the whole machine if it must be exceptionally operated under such conditions or gets into touch
with these materials. Additionally, the machine must be checked as described under 3.9.

5 Function of individual components
5.1 Gerneral
LUKAS Telescopic cylinders are equipped with several pistons one fitting into the other among
which the total stroke is divided.
Characteristics:
- Small overall size in relation to stroke.
- Different lifting capacity in the individual stages due to different piston diameters.
Please observe the max. lifting capacity of the different pistons with a view to the max.
permissible load of support blocks used with the cylinder. This especially applies to the
permissible load for shifting devices of LUKAS rerailing equipment.
- Max. working pressure is 53 MPa (530 bar).
