Page 106 SUA 125 NUMERIC Warning: Spindle start will only then allowed when the reference points are against positions. Warning: In the moment of the change of transmission speed range dont open any safety guard! Note: In case that above mentioned state may happen, make the small movement from arrested position with lever for given transmission range and give the lever back into same arrested positions.

SUA 125 NUMERIC 11.4. Longitudinal and transversal stops. 11.4.1. Transversal stops (Fig.B) consist the couple of stops. • retarding • limit • emergency on one body (1) steady fixed with holder of ball nut (2) and couple of switches SQ 1,2,3 and SQ 4,5,6.
Page 108 SUA 125 NUMERIC Adjust the working position of longitudinal stops at tailstock acc. to required length L and it must be taken into consideration also the steady stops on the proper tailstock and switch SQ 7, 8, 9 steady connected with saddle, which limitate the distance between tailstock and saddle.

SUA 125 NUMERIC Maintenance and testing of lathe. 12.1. Inspection. The inspection connected with - safety of operation. - reliability of operation. should be ensured by the lathe user in course of lathe life. The inspections of safety of operation are laid down by law and safety regulations in users’s country.
Page 112: Operation Breakdown
SUA 125 NUMERIC Operation breakdown When the power supply to the main electric motor and hydraulic circuit electric motor is broken, the work spindle of lathe will be stopped. The breakdown in the hydraulic circuit - a decrease in pressure, leads to spindle brake to stop.
Page 113: Data For Urgent Help
SUA 125 NUMERIC Data for urgent help. Lathe is equiped with an emergency stopping device in case of urgent help and hazard which is connected with the machining process. Hazards can be occured: - as a result of irregularities (malfunction of lathe, inacceptable characteristics of machined material, operator fault, etc.).
