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
specications, 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.
