1 Basic operation and designated use of the machine 1.1 The machine has been built in accordance with state-of-the-art standards and the recognized safety rules. Nevertheless, its use may constitute a risk to life and limb of the user or of third parties, or cause damage to the machine and to other material property. 1.
.2 Before starting up or setting the machine in motion and during operation of the machine make sure that nobody is at risk. 3.3 Before transporting the machine always check that the accessories have been safely stowed away. 3.4 Make sure that there is enough lighting during work. 3.5 Avoid any operation that might be a risk to machine stability. 3.6 Check the machine at least after every operation for obvious damage and defects. Report any changes (incl.
5 Safety instructions for hydraulic hoses All instructions to safe use of hydraulic hoses can be found in the booklet HR 1495 35 219 delivered with the hoses. 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 (500/700 bar) are connected, they may be damaged. Used oil must be disposed of at a used oil disposal station to avoid environmental pollution.
6.1.2 Power pack type PO4-4-N3-500 and PO4-4-N3-700 (see function diagram) The version N3 includes a 3/3-way valve. 6.1.2.1 Operation (see fig. 2) In position I (A) the cylinder extends when the pump is switched on. In position 0 (centre position of the operating lever) pressure maintaining function at oil flow from P ---> T. In position II the piston side of the cylinder is connected to the oil tank and the cylinder is retracted by means of a return spring.
.3 Electric control The 3-step switch is located on the side of the plastic housing. - Top position - position I the motor is started. - Centre position - position 0 motor standstill. - Bottom position - position II the electronic equipment is started, the motor, however, is not switched on, but will be started via the remote control. 6.4 Thermostat The power pack is equipped with a thermostat, which protects the motor against too high temperatures by switching it off to avoid damages.
8 Option The equipment described below is not part of the standard scope of supply, but special equipment which is to be purchased separately. 8.1 Pressure gauges (item. 11 fig. 10) 8.1.1 For type PO4-NA MEG 500 MEG 700 Remove screw plug G 1/4 in connection P above the connection board. Screw in the pressure gauge with the stem. 8.1.2 For type PO4-N3 / PO4-N4 MEL 500 MEL 700 Insert the pressure gauge adapter directly into the connection bore A. 8.
9.3 Preventive Maintenance The oil tank must principally be cleaned with each oil change. To clean the oil tank, the mounting screws on the oil tank cover must be loosened and the motor/ pump unit pulled out. Attention The tank must be cleaned by flushing with hydraulic oil. Do not use textiles! 10 Service Service may be carried out exclusively by the manufacturer of the device or by personnel trained by the manufacturer and the authorized dealer.
