7.2 Connection diagram
For your better understanding the hydraulic diagram is showing
in simplified manner the tool's hydrauliccylinder (A) with control
valve (B).
7.3 Control of movements in operation
The arm movement is controlled by the firmly mounted star grip control valve (see cover page
item 1).
7.4 Hydraulic oil supply
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 fulfils
the LUKAS specifications, 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 63 MPa (630
bar) is not exceeded.
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.
8 Connection of the tool
8.1 Hydraulic
Two short hoses (each 0.5 m long) are fitted 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 = reflux ——> 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.
