4.4 Always tighten any screwed and thread connections that have been loosened during
maintenance and repair. Observe the stipulated torques.
4.5 Work on the electrical system or equipment may only be carried out by a skilled electrician
himself or by specially instructed personnel under the control and supervision of such electrician
and in accordance with the applicable electrical engineering rules.
4.6 The electrical equipment of machines is to be inspected and checked at regular intervals.
Defects such as loose connections or scorched cables must be rectified immediately.
4.7 Aggressive material (acid, lye, solvent, vapour) can damage the machine. It is necessary to
clean the whole machine if it must be exceptionally operated under such conditions or gets into
touch with these materials. Additionally, the machine must be checked as described under 3.6.
Device-specific information
Ensure the correct power supply acc. to the motor data on the nameplate.
If external devices with operating pressures < 50/70 MPa are connected, they may be damaged.
Used oil must be disposed of at a used oil disposal station to avoid environmental pollution.

5 Intended use
LUKAS hydraulic power packs are exclusively designed for the operation of LUKAS hydraulic
cylinders. Hose nipples and hoses are not part of the power pack's scope of supply and can be
obtained from LUKAS.
6 Description
6.1 Drive system
6.1.1 The motor pump serves as hydraulic power supply. It includes a LUKAS radial piston
pump with:
- Low pressure circuit (up to 16 MPa) = LP. -
High pressure circuit (up to 50 resp. 70 MPa)= HP.
6.1.2 Following drive motors are available:
- electric motors single-phase AC with voltage 115V / 230 V
- 4-stroke combustion engine
6.1.3 Necessary valves are integrated in the pump unit:
- Switch-over from low to high pressure mode is made automatically by a pressure limiting
valve.
- The maximum working pressure is limited by a pressure relief valve set to 50 resp. 70 MPa.
6.1.4 Power packs with 10 l oil container
The oil container is filled ex works with 7.5 l of hydraulic oil. If necessary, the oil container can be
filled up to a total volume of 10l. The filler plug for hydraulic oil (fig. 1) includes a dipstick with 3 marks:
1 = min. oil level 5 l ; 2 = standard oil level 7.5 l ; 3 = max. oil level 9 l
