1 Basic operation and designated use of the machine
1.1 The machine has been built in accordance with state-of-the-art standards and the recognized
safety rules. Nevertheless, its use may constitute a risk to life and limb of the user or of third parties,
or cause damage to the machine and to other material property.
1.2 The machine must only be used in technically perfect condition in accordance with its
designated use and the instructions set out in the operating manual, and only by safety-conscious
persons who are fully aware of the risks involved in operating the machine. Any functional disorders,
especially those affecting the safety of the machine/plant, should therefore be rectified immediately.
1.3 The machine is exclusively designed for the use described in the operating manual. Using
the machine for purposes other than those mentioned in the manual, such as driving and controlling
other pneumatic systems, is considered contrary to its designated use. The manufacturer/
supplier cannot be held liable for any damage resulting from such use. The risk of such misuse lies
entirely with the user.
Operating the machine within the limits of its designated use also involves observing the
instructions set out in the operating manual and complying with the inspection and maintenance
directives.
2 Organizational measures
2.1 The operating instructions must always be at hand at the place of use of the machine.
2.2 In addition to the operating instructions, observe and instruct the user in all other generally
applicable legal and other mandatory regulations relevant to accident prevention and environmental protection.
This also applies for wearing protective clothing, helmet with visor or goggles and protective gloves.
2.3 In order to avoid injuries, the machine must only be operated by a specially trained operator
who has undergone a safety training.
2.4 Observe all safety instructions and warnings attached to the machine. Make sure that safety
instructions and warnings attached to the machine are always complete and perfectly legible.
2.5 Never make any modifications, additions or conversions which might affect safety without the
supplier’s approval. This also applies to the installation and adjustment of safety devices and
valves.
2.6 Spare parts must comply with the technical requirements specified by the manufacturer.
Spare parts from original equipment manufacturers can be relied to do so. It is only allowed to
use original LUKAS spare parts or LUKAS system components.
2.7 Replace hydraulic hoses within stipulated and appropriate intervals even if no safety-relevant
defects have been detected. This has to be done after 10 years at the latest.
2.8 Adhere to prescribed intervals or those specified in the operating instructions for routine
checks and inspections.
2.9 Make sure to dispose properly of packing material and dismounted parts!
3 General safety instructions
3.1 In the event of malfunctions, stop the machine immediately and lock it! Have any defects
rectified immediately.

3.2 Before starting up or setting the machine in motion and during operation of the machine make
sure that nobody is at risk.
3.3 Before transporting the machine always check that the accessories have been safely stowed
away.
3.4 Make sure that there is enough lighting during work.
3.5 Avoid any operation that might be a risk to machine stability.
3.6 Check the machine at least after every operation for obvious damage and defects. Report any
changes (incl. changes in the machine’s working behaviour) to the competent organization/person
immediately. If necessary, stop the machine immediately and lock it. All lines, hoses and screwed
connections have to be checked for leaks and obvious damage. Repair damage immediately.
Splashed oil may cause injury and fire.
3.7 All safety equipment has to be checked for completeness and flawless condition:
- instruction markings and warning signs (safety instructions)
- check safety cover (e.g. motor-safety covers, heat protection etc.) if they are available and if they
are in good condition.
3.8 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.
3.9 Make sure that hoses are not mechanically stressed (pulling, bending etc.).
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
maintenance and repair. Observe the stipulated torques!
4.5 Work on the electrical system or equipment may only be carried out by a skilled electrician
himself or by specially instructed personnel under the control and supervision of such electrician
and in accordance with the applicable electrical engineering rules.
4.6 The electrical equipment of machines is to be inspected and checked at regular intervals.
Defects such as loose connections or scorched cables must be rectified immediately.
4.7 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 3.6.
