6.2.3 LSI cutter with cylinder bottom
The cutter with cylinder bottom is controlled with pressure to the correspondingly
labelled connection nipple (see first page pos. 10). Control is not directly on the
tool, but through external controls.
The blades are opened with pressure to connector
nipple „B“.
The blades are closed with pressure to connector
nipple „A“.
6.3 Hydraulic power
Only LUKAS hydraulic aggregate should be used to operate the device. If the
pump aggregate is made by another manufacturer, please ensure that it is
designed in accordance with LUKAS specifications, as otherwise potential
dangers can occur, for which LUKAS cannot be responsible. If in doubt, contact
the authorised LUKAS dealer or LUKAS direct.
Ensure that the
permissible operating pressure
for LUKAS LSI devices of
50
MPa (= 500 bar)
is not exceeded without consulting LUKAS.
6.4 Hose lines
The connection between pump aggregate and cutting tool is normally via LUKAS
hose lines.
When connecting a piping, contact LUKAS directly
in advance

Connecting the device
7.1 Hydraulical
7.1.1
LSI cutter with 4/3-way valve or with electrical controls
The device has two hose lines; these are connected with the pump aggregate via
a pair of hoses (5 m or 10 m as required). All hose lines are colour marked and
fitted with quick connectors so that they cannot be mistaken:
HP = High pressure ——>red
R = Return ——>blue
7.1.2
LSI cutter with cylinder bottom
The device has two connectors for hose lines; these will be connected with the
pump aggregate via a pair of hoses (5 m or 10 m as required) (not included in the
delivery). The hose lines are directly screwed to the cylinder bottom and tightened
with a torque of 45Nm. Ensure that the high pressure hose are screwed into
connection „A“ and the return hose is screwed to connection „B“!
7.2 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 conterparts
(plug and socket), there being no risk of mix-up.
When connecting the hoses, be aware of the following basic functions of the quick
couplers:
