Depending on the destination country, Euroquick coupling is installed.See section 4-006, pages 36-43, for the wiring diagram.Connection:Warning:Once the machine is connected pneumatically (pressure), the vertical bore head motor supportwith the gearbox can move up and the horizontal bore head motor support with the gearbox canmove back.a) Lift the setting knob of the maintenance unit and turn counterclockwise.b) Connect the pneumatic air pressure with a quick coupling or shut-off valve with an exhaust.It has to be connected so that the machine operators can disconnect the machine from the pneumaticductwork system at anytime within a maximum distance of 3 meters.c) Turn the regulator clockwise until the pressure gauge of the maintenance unit indicates about5.5 to 6 bar (0.55 - 0.6 MPa). Press the setting knob back down.d) Test if it functions with the main switch turned off and without the drill bit. By activating the start button,the motor support has to move downward. When the button is released, the machine returns immediatelyto its starting position.e) Check the pneumatic hold-down device (accessory) to see if it operates properly.6-002 Electric connectionsThe machine is equipped with a 3-meter long 5-pole connecting cable. Depending on the destinationcountry, a socket (CEE 5 x 16A) is installed.See section 4-007, pages 44 and 45, for the wiring diagram.Warning:Only authorized technicians or licensed electricians should hook up this machine. They mustcomply with the codes and regulations applicable in the respective country.If any maintenance work is to be done on the electrical system of the Multipress, the machinemust be disconnected from the power supply by pulling out the plug or by means of a switch thatcan be locked.After the start-up is completed in accordance with section 6-001, and the hook-up to the power supply iscompleted, turn on the main switch, swing the insertion die arm completely up, and without a drill bit, pressthe vertical motion start button “2“, illustration 4-004-01, until the motor starts.
