5.5 Periods for checking and replacing hose lines
- Check the hose lines for external damage, tears, bends and inflating after
every use.
- The operator must ensure that hose lines are replaced at reasonable intervals,
even if no safety deficiencies can be detected on the hose.
- The hose line must be replaced 10 years after manufacture at the latest (see
label)!
- Hose lines must be checked before first start-up of the technical equipment
and then at least once a year to ensure a safe working condition by a properly
trained person. For examples of possible deficiencies, see 5.6 below.
5.6 Examples of possible deficiencies to hose lines
- Damage to the external layer to the insert (e.g. chafing, cuts or tears).
- External layer becoming brittle (tears to the hose material).
- Deformations not corresponding to the natural shape of the hose when under
pressure or depressurised, or when bent, e.g. separation of layers, bubbles,
squashed areas, bends.
- Leaks.
- Installation requirements not observed.
- Hose leaves the fittings.
- Damage or deformation to the fittings which alleviates the function and stability of
the fittings or the hose – fittings connection.
- Corroded fittings or metal inserts, which alleviates the stability.
- Storage times and period of use exceeded.
6 Indented use
LSI 600E and 400E cutters are exclusively to be connected to a LUKAS power package
of series PO... / LSI being equipped with a suitable electromagnetic valve assembly.
Model LSI 600 comes without any control valve. It is meant for stationary use and is to
be operated by a taylor-made LUKAS power unit.
All cutters serve for cutting steel, sufficiently hard ferrous metals or cables.
7 Description
7.1 Cutters
The devices are designed in such a way that a hydraulically actuated piston via
mechanical joints symmetrically closes two identical cutter blades positioned opposite
each other to cut the object in question. The blade geometry is adapted to the application
so as to avoid as for as possible sliding of the material to be cut between the blades.
Opening of the blades is also effected by hydraulic-mechanical means (with reduced power).

device, the connection diagram shows the complete
unit (cutter unit and pump power pack).
