Rectifying faults Customer checklist 7 Rectifying faults All products are subject to rigorous production checks and final checks. If, despite this, something fails to work at any time, please check the product using the following flowchart. If none of the fault rectification procedures described leads to the correct functioning of the product, please inform your authorised dealer. 7.
Rectifying faults Check the machine type setting 7.2 Check the machine type setting NOTE Only with the M2.xx machine control. After switching on, the machine type that has been set is displayed for a short time, denoted as "tyP". If the machine type displayed does not match the machine, you have to correct this setting. „tyP 00“ „tyP d00“ „tyP 01“ „tyP r01“ „tyP 02“ „tyP d02“ „tyP d03” „tyP d04” 7.2.1 Saturn 251 Saturn 256 Saturn 301 Mira 301 (M2.
Rectifying faults Resetting the control (Reset all) 7.3 Resetting the control (Reset all) NOTE M2.xx control The first action should always be to check and if necessary correct the machine type setting. All user settings will be overwritten with factory settings and must therefore be checked afterwards, or set up again! After resetting the machine control to the factory settings, it is essential that the machine type used is checked and reset if necessary.
Rectifying faults Vent coolant circuit 7.4 Vent coolant circuit NOTE If there is less coolant in the coolant tank than the minimum required you may need to vent the coolant circuit.
