4.5 Hydraulic supply
A LUKAS motor pump or hand pump only may be used to drive the equipment.
If the pump unit is a different make, you must make sure that it complies with LUKAS
specifications, otherwise potential dangers may occur which are not the responsibility of
LUKAS. Ensure in particular that the authorised operating pressure for LUKAS equipment
is not exceeded.
NOTE:
Before you use pumps from a different manufacturer, you must contact LUKAS
or an authorised dealer.
