When the loading door is closed pushing the proper button, if the piece is blocked the clamping pressure goes up to high pressure.? Automatic Mode (selector and CN)Pressing the pedal with the loading door open causes the blockage of the piece at low pressure (pneumatic clamps) and by vacuum (if the vacuum pump has been turned on)。 pressing the pedal again (with the loading door open) the piece will be unblocked. When the loading door is closed pushing the proper button, if the piece is blocked the clamping pressure goes up to high pressure.321INSTRUCTION MANUAL MASTER User Interface 7In Automatic mode the opening of the loading door is driven by program (unblock mand), then it is possible to unblock the piece using the pedal。 the lubrication time intervals are controlled by the CNC. ? Periodically check the working and efficiency of the automatic lubrication system!For the automatic lubrication system refilling, the use of one of the following products is remended:NLGI0 (or equivalent)NLGI1 (or equivalent)? Use only grease resistant to high pressure. Otherwise if oils and soaps inside grease are separated, soaps can solidify and obturate the pneumatic installation.INSTRUCTION MANUAL MASTER User Interface 18Pneumatic installation lubrication system The lubricant in the pneumatic installation must be periodically checked and in case refilled with one of the products listed here, or with an hydraulic oil class ISO/UNI F or ISO/UNI H.AGIP Oso 10ESSO Nuto H 5MOBIL Velocite Oil Q8 Puccini 4PTEXACO 300 Oil 5TOTAL Azolla ZS 15There are no noticeable differences between the oils here indicated.

Uplifting ropes and poles are not supplied with the machine and must be properly dimensioned, like the crane and any other ponent used for this operation. The ropes anchored to the poles on the basement rear part (the opposite side with respect to the operating head) must be aside the basement, while those on the fore part must be placed approximately 400mm away from the basement in order to balance the moment due to the machine weight distribution.Uplifting scheme:The holes for uplifting poles have a diameter of 80mm.Machine weight is about 4000kg. Once uloaded with the crane, the basement can be moved with a forklift expediently dimensioned.The electric cabi has 4 hooks to fix ropes for lifting. The two Y tables can be unloaded and moved using a forklift.Rear ropes aside the basement40CM 40CMFore ropes 400mm away from the basementINSTRUCTION MANUAL MASTER User Interface 22SafetyFor a safe operation with MASTER machining center it is necessary to strictly follow the procedures herein described. Notwithstanding all the safety devices which are included in the machine, an improper or unconscious use can cause serious damage to the machine itself or serious injuries to the operator.SpindlesBefore turning on the spindles it is fundamental to: make sure that
