X5 (3): the data logger is connected here for readout of operating data. X5 is also im-
portant for setting the service interval.
Service interval settings:
Switch off the machine with S1. Place a wire jumper (9) between pins 3 and 5 on X5.
Switch on the machine ("Cold water" mode). By temperature setting it is now possible
to set a new service interval, read from the status display LEDs (4-8): beginning with
the "Fuel" LED (4), each LED stands for 100 h, producing a setting range of 100 to 500
h in 100 h increments. If the setting is not altered for 3 s, the value is assumed, indica-
ted by flashing of the set LEDs. The machine must then be switched off by S1, and the
wire jumper removed from X5. The default ex works is 200 h.
