SECTION D WORKING WITH HYDRAULIC POWER PACK
The power pack work is determined by the machine at which it is integrated. At work with the power
pack it is not allowed the presence of leakage of working fluid on the outside surfaces. The power pack is
switched when the motor is supplied with the necessary voltage. The control is effected by proper
combination of switching on the motor and the solenoid valves.
SECTION E: POWER PACK ASSEMBLY
E1 REQUIREMENT OF THE WORKING AREA
The power pack must be mounted using M10 holes if there is no mounting bracket. The working area
around the power pack must be free and an access to the oil filler, to the valves and the unloading throttle
has to be ensured. The power packs must not be placed in closed areas that may prevent its cooling. The
power pack should not contact with any parts that may vibrate and transmit noise.
E2 TRANSPORT OF THE HYDRAULIC POWER PACK
The power pack can be transported with any kind of covered transport. At its transporting it should be
observed the recommendations on the carton. If there is oil inside the tank during transportation, air breather
should be replaced with blind plug or oil should be pour out before transport.
E3 POWER PACK PROTECTION
The hydraulic power pack is taken out of the carton. The polyethylene packing is removed of it. The
safety plugs are replaced of the supply ports.
E4 CONNECTING PORTS
There are two letters on main manifold which refer to pump (pressure) and tank lines. P refers to
pump line and T refers to tank line. Both ports are G 3/8’’ as standard. Max. tightening torque of fittings is 65
Nm.
