5.1 Handling of hoses
- never exceed the permissible working pressure as stated on hose and/or literature
- avoid any tension (see fi gure 1) and do not hang any load onto the hose
- never exceed the minimum bend radius as resulting kink will cause failure of hose
(see fi gure 2)
- do not allow hose to contact sharp edges or rough objects (see fi gure 3)
- avoid any twisting of hose (see fi gure 4)
- do not run over hose with any vehicle or equipment ! Hoses which are put on the
surface of sidewalk or street have to be suitably protected (see fi gure 5)
- do not allow hose to contact areas of high temperature such as muffl ers, exhaust
manifold, heaters or burners. Protect the hose as shown in fi gure 6 or install it in
suffi cient distance from the source of heat.
- never interline hose with that of a different manufacturer.
5.2 Protection of the working area in case of breakdown of hoses
Hoses have to be installed or protected in such a way that dangers are prevented, if
possible, in case of breakdown of the hoses.
Danger can be caused by:
- Uncontrolled hose movement after a hose rupture caused e.g. by external infl uence.
- Emerging of the pressure medium under pressure.
- Infl ammation of pressure medium near igniting sources.
7
5.2.1 Do not go near leaks!
- High pressure oil easily punctures skin causing
serious injury, gangrene or death!
- If injured, seek emergency medical help!
Immediate surgery is required to remove oil!
- Do not use fi nger or skin to check for leaks!
- Lower load or relieve hydraulic pressure before
loosening fi nttings!
5.3 Storage of hoses
- Hoses are subject to a natural aging even if they are stored correctly. Therefore,
their storage and service time is limited.
When storing the hoses please observe the following:
- Store them cool, dry and dustless (eventually wrapped with plastics sheeting);
prevent direct solar radiation and UV rays; shield heat sources which are near the
hoses.
- Do not use any ozone producing lamps (e.g. fl uorescent light sources, mercury vapor lamp) or electrical devices next to the hoses.
- Hoses have to be stored freely of tension and in a horizontal position. If they are
stored in rings the smallest bending radius determined by the manufacturer must
not fall below.
5.4 Marking of hoses
- The hose is marked with the manufacturer‘s name and quarter/year of production.
- The max. allowable pressure and month/year of production is indicated on the
hose end fi tting.
5.5 Inspection and replacement intervals of hoses
- After each operation the hoses have to be checked for external damages,
cracks, kinks and bubbles!
- The operator has to replace the hoses in appropriate period of times, even if there
are no visible security defects on the hoses.
- The hoses have to be replaced 10 years as from date of manufacture at the
latest (see marking on the hose)!
Hoses are subject to a natural aging even if they are stored correctly. Therefore,
their storage and service time is limited.
- Hoses have to be checked by a skilled person before the fi rst putting into
operation of the technical device and afterwards at least once a year for their
safe working condition.
A skilled person is somebody having suffi cient knowledge concerning hydraulic hoses
due to his special training and knowledge. He/she must be acquainted with the local
safety working conditions, accident prevention regulations, technical regulations and
approved standards (e.g. DIN-Standards), so that he/she is capable to estimate the
8
5.6 Examples for possible defects of hoses
- Damages of the surface and the interior (e.g. chafe marks, cuts or fi ssures).
- Embrittlement of the surface (fi ssuration of the hose material).
- Deformations, which are not in accordance with the natural shape of the hoses, in
pressureless condition or under pressure or in case of bendings, e.g. separation
of material layers, blister formation, squeezing or break spots.
- Leakage points.
- Instructions for installation were not observed.
- Emerging of the hose from the end fi ttings.
- Damages or deformations of the end fi ttings which deteriorate the function and
stability of the end fi ttings or the connection between hose and end fi tting.
- Corrosion of the end fi ttings or the metal inlets, which deteriorates the function and
stability.
- Storage and operation periods were exceeded.
6 Intended use
LUKAS LSI cutters are specially designed for cutting steel, suffi ciently hard ferrous
metals, sheet steel and cables. Depending on the material to be cut, cutter blades in
different shapes are available.
7 Function and performance
7.1 Description
The devices are designed in such a way that a hydraulically actuated piston via mechanical joints symmetrically closes two identical blade arms 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 a sliding of the material to be cut.
7.2 Connection diagram
For your better understanding the hydraulic diagram
is showing in simplifi ed manner the tool‘s hydraulic
cylinder (A) with control valve (B).
7.3 Control of movements in operation
The arm movement is controlled by the fi rmly mounted star grip control valve (see
cover page item 1).
7.4 Hydraulic oil supply
Only LUKAS motor/engine pump or hand pump is used for operating the devices.
If the power pack comes from a manufacturer other than LUKAS, it must be ensured that
it fulfi ls the LUKAS specifi cations, as otherwise dangers may occur for which LUKAS
cannot be held liable. Especially it has to be made sure that the permissible working
pressure of 50 MPa (500 bar) is not exceeded without consultation with LUKAS.
7.5 Hoses
The connection between motor pump and cutter unit is normally effected with LUKAS
hoses. If pipes are to be used, please contact LUKAS.
9
8 Connection of the tool
8.1 Hydraulic
Two short hoses are fi tted to the tool; they are connected with the motor pump via a
hose pair (5 m / 10 m / 20 m, as is necessary). All hoses are colour marked and have
quick-connect couplings so that they can be connected without the risk of mix-up:
HP = High pressure ——> red R = refl ux ——> blue.
8.2 Connection of the plug-in coupling counterparts for HP and R
hoses
The device is connected to the hydraulic pump with the plug-in coupling counterparts
(plug and socket), there being no risk of mix-up.
Before coupling, remove the dust protection covers and unlock the connect socket with
adjusting ring by turning it. Withdraw the sleeve and connect plug and socket while
holding the sleeve in this position. Release the sleeve and set the showglass to „red“
with the adjusting ring. Now the parts are connected and locked. Decoupling is done
in the reverse order.
Note regarding the modifi ed release mechanism as of June 2003
When connecting the hoses, be aware of the following basic functions of the quick
couplers:
Set the sleeve to position X and pull it back • separate plug and socket • for connection
of a tool,
reverse this prodecure.
Connection of the hoses is possible only, when they are depressurized.
In order to prevent contamination of the tool lines protect the couplings with delivered
X
10
Attention!
Quick couplers partly have special functions. Therefore it is not allowed screwing
them off from the hoses or to exchange them.
9 Operation
9.1 Preparatory measures
9.1.1 Initial start-up
Check the machine before initial start-up for obvious damage and defects. All lines, hoses
and screwed connections have to be checked for leaks and obvious damage.
Before initial start-up and after repairs, the device must be vented:
- Connect the device to the hydraulic pump (see item 8).
- Fully open and close the device at least twice without load (see item 9.2).
9.1.2 Inspection of operating state of the pump power pack
——> See separate Operating Instructions of the power pack (or manual pump) in
question.
Note:
Before working on the motor pump or for coupling/decoupling the hoses, make sure that
the motor pump is switched off (electric connection) or disconnected from the mains
and that the lines are unpressurized.
9.2 Operating of the star grip 1
Opening of the blades:
Rotate star shape ring 1 to the right hand side and hold it in this position.
Closing of the blades:
Rotate star shape ring 1 to the left hand side and hold it in this position.
Load sustain function:
If released, the star shape ring 1 returns automatically to center position, maintaining
fully the load sustain function.
10 Cutting
10.1 Safety advise
In each country, the country-specifi c safety regulations must be regarded.
When working in an environment which involves a risk of explosions, do not use motor/
engine powered pumps. Instead, use hand pumps.
When operating cutter devices, wear
- protective clothing
- helmet with visor or goggles
- protective gloves.
Before any operation of the cutter unit make sure that the movement of the blades does
not constitue a risk to persons or that the blades or cut-off parts jerking away cannot
damage property.
Do not get your hands in between the blade arms.
Do not cut
- live wires,
- pressurized gas or fl uid lines,
- prestressed and hardened parts (such as springs, spring steels, steering columns,
11
10.2 Principles on cutting
The blades must be applied at a right
angle to the object to be cut. To enhance
cutting performance, cut as close as
possible to the blade fulcrum. On cutting,
the gap between the blade tips must not
be larger than 3 mm (Risk of blade fracture!).
10.2.1 Attention!
With cutters having curved blades the blade tips must by no means be loaded with full
cutting capacity. Cutting of profi les of up to 2 mm thickness is permissible.
11 Dismantling of the device / Stop after operation
11.1 Cutter unit
After operation, close the blades to a distance of a few mm. This relaxes the unit
hydraulically and mechanically.
11.2 Hydraulic power pack
Stop the hydraulic power pack after operation.
This is mandatory before taking one of the following steps:
11.3 Hoses
Uncouple the red hose fi rst and the blue hose second as described under 8.2. Put dust
caps over the couplings.
12 Maintenance
After each operation inspect the components for perfect function (when the device is
dirty, clean it before inspection):
Visual inspection
Cutter blades
• Cutting edges free from spalling and deformation.
• Distance of blades in transverse direction < 1mm.
• Cutting surfaces slide past each other without contact.
• Blades free from cracks.
• Corrugation of the tips clean and edged without fi ssures.
Cutter unit
• No leakages.
• Easy operation of the star grip.
• Handle existing and fast.
• Check of central bolt tightening torque (see also drawing to Section 13.3.1)
MA = Torque (see item 15.2).
Hoses
• Check according safety instructions for hoses (see item 5).
• Check for oil leakage.
Function testing
• Perfect opening and closing with the star grip valve.
12
13 Repairs
13.1 General
Servicing must be carried out only by the device manufacturer or by personnel trained
by the manufacturer or the authorised LUKAS dealers.
For replacement on all components, use only genuine LUKAS spare parts as specifi ed
in the spare parts list, as here possibly required special tools, mounting information,
safety aspects, testing must absolutely be taken into account. See section 4.
Protection of the device against hydraulic overload
Through uncorrect hose connection or temperature increase pressure can be built up
in the cylinder unintentionally. Therefore, the return hose (0,5 m / blue) of the tool is
equipped with a safety coupling (quick connect plug, colour yellow). Overpressure (approx. 1.5 MPa) is released through this plug: oil comes out. This oil is not a malfunction
of the plug!
Should the tool have been equipped with couplers of different brand which do not have this safety
function, overpressure would be released through another safety valve (adjusted to approx.
30 MPa) included with the control valve block. In this case oil spill would be observed
in the star grip area.
As soon as suffi cient pressure is released the valve becomes tight again. Should further
constant leakage ocur, please have the tool inspected by LUKAS personnel.
13.2 Preventive maintenance
13.2.1 Routine inspections
Regularly check the central bolt tightening torque. MA = Torque (see item 15.2).
Damaged blades can be repaired by regrinding of the cutting edge up to a total of 0.5
mm. Special care must be taken to have the inner cutting faces run parallel.
Attention !
When you are working with the cutter blades pointing upwards, it must be made sure
that no larger objects are falling into the rubber protection boot. Such objects might get
jammed into the lever system which can cause serious damage to the tool.
After each application in upright position the cutter head must be inspected on eventual
pollution, and it must be cleaned if necessary
picture 1
Remove handle and pull the protection boot back.
13
picture 2
Clean the mechanical parts (see picture 2) with compressed air from dirt and metal
chips.
If the upper sealing lips of the protection boot are damaged too seriously, the boot must
be changed against a new one.
13.2.2 General inspections
The mechanical transmission elements of the cutter unit are subjected to very high
mechanical stressing and must, therefore, be inspected at certain intervals. This helps
to detect wear early so that fractures of these wearing parts can be prevented by
replacing them in time.
Parts in perfect condition can be fi tted again after careful application of LUKAS special
grease for cutter units.
Parts with insignifi cant wear (fretting marks) can be repaired by polishing and fi tted
again after greasing.
More pronounced wear marks require replacement of the damaged parts (by pairs).
At these intervals, crack testing of the cutter blades is equally mandatory. For this
purpose, a special crack test kit is available.
To protect the device against external corrosion clean its surface from time to time and
slightly grease it with oil.
13.2.3 Function and load test
If there is any doubt as to the safety and reliability of the equpiment, carry out an
additional function and load test. For this purpose, LUKAS offers a test kit as appropriate
equipment.
13.2.4 Change of hydraulic oil
- After 200 uses, latest after 2 years, the hydraulic oil has to be changed.
- In any case if the oil of the pump (motor / hand pump) which belongs to the unit
is changed. By changing the used oil, it should be avoided that the new oil is pol-
14
Procedure:
The cutter tool is in closed (retracted) position • Change of oil has to be effected at the
pump.
Screw off the return hose at the pump:
- in case of hose connection: screw off the connecting piece of the blue return
hose.
- in case of quick connect couplings: screw off totally the coupling nut of the
quick connect coupling of the blue return hose.
Extend pump with tool slowly • Collect the used oil at the piston rod side in a separate
tank and dispose of the used oil (as the used oil of the pump) • Do not operate the
pump any longer.
Connect the return hose again to the pump:
- Tighten the coupling nut of the quick connect coupling according to 13.3.6,
- Screw the hose nipple into the valve bloc with MA = 45 Nm,
- Ventilate the tool according to 9.1.1.
13.3 Repairs
13.3.1 Cutter blades and levers
Cutter blades and levers have to be replaced in the case of visual heavy damge and cracks
or when the blades are becoming too weak due to frequent regrinding. (13.2.1).
- Unscrew the nut of the central bolt (size open-jawed
spanner see 15.2) and drive out the central bolt.
- Remove the retaining rings with a pair of Seeger ring
pliers.
- Replace the blade arms after thorough cleaning and
greasing of the sliding surfaces.
- Tighten the nut of the central bolt with the tightening
torque specifi ed in 15.2.
- Note:
The bolts are accessible with the blade arms closed.
Attention: prior to mounting all sliding surfaces have to be carefully cleaned and greased
with LUKAS special grease.
Remark: Faulty parts such as blades, bolts or sliding disks have to be changed pairwise.
The levers have to be replaced if e.g. during change of blades damages appear such
as wear on the surface, cracks or deformation of the bores. Lever exchange should be
made by a authorized LUKAS dealer or the LUKAS service department.
13.3.2 Oil spill out of the control valve handle (see cover page item 10)
Pressure or return hose are not tightened properly.
Procedure:
Loosen the 2 allen screws (SW5) inside the handle sleeve and remove them together
with the short plastic isolation sleeves. Pull handle sleeve backwards until the hose
connection points become visible and retighten the retaining nut. Change hose connection sealing rings if necessary. Place handle sleeve again and tighten it with the 2
allen screws. Make sure that the plastic isolation sleeves are placed properly on the
allen screws before mounting.
13.3.3 Change of protection boot
The rubber protection boot shall protect the operator against injuries caused by the
15
Procedure:
Remove the carrying handle (held by 2 screws) • Dismount cutter blades / blade arms
(see 13.3.1) • pull the faulty boot from the cylinder body and place the new one properly,
i.e. that the carrying handle fi xing screws go easily through the corresponding holes in
the boot. Mount and tighten carrying handle.
13.3.4 Carrying handle (see cover page item 11)
Damaged carrying handles have to be replaced immediately.
Procedure:
Remove the handle (held by 2 screws) and change it against a new one • Change

For daily use it is to be distinguished between max. cutting performance and cutting
performance under permanent duty.
In the interest of a long tool life and acceptable service intervals, we recommend not to
exceed permanently the fi gures given for permanent duty. Applications in the range of
the max. cutting performance require a perfect condition of the blades and shortened
service intervals.
