5.4 Hose lines
Only LUKAS motor pumps (or hand pumps in exceptional cases) may be used to drive the
devices.
If the pump unit is of a different make, you must make sure that it complies with LUKAS
specifications, otherwise hazards may occur which are not the responsibility of LUKAS.
Ensure in particular that the maximum permissible operating pressure for the connected
LUKAS equipment is not exceeded.
NOTE:
Before you use pumps from a different manufacturer, you must contact LUKAS
or an authorised dealer.
The pump unit and the HP cylinder are connected by hoses.
