OPERATING INSTRUCTIONS 6030, 6030FS Operation Fuel preheating system (optional) Fuel preheating system, function At temperatures below 0°C / 32°F, the paraffin particles contained in the diesel fuel begin to clump together. They form flakes which clog up the fuel lines and the filters. Starting of the engine is then no longer possible. To prevent this, the diesel fuel must be preheated. Preheating is effeceted by means of two heating elements in the fuel line. The heating elements are attached to the engines. They are equipped with internal thermostats ensuring an automatic temperature regulation. Switch on the fuel preheating only after preheating of the engine and of the hydraulic oil is terminated (see "Preheating system for engine and hydraulic oil (option)"). The preheating time is dependent on the outside temperature.

Switching the fuel preheating system on and off Switch on the ignition by turning key-switch (32, Fig. 2-90:) to position 1. At temperatures below 0°C / 32°F, switch on the fuel preheating: switch (144, Fig. 2-91:) for the lefthand engine, switch (143) for the righthand engine. The pilot lamp located above the resp. switch lights up.
Fig. 2-91:
After a short time start up the engines (see also "Starting and stopping the engines"). Switch off the fuel preheating with switches (143 and 144), when the engines has reached their operating temperatures. The pilot lamp (Fig. 2-91:) goes out.
