Operation Oil and fuel preheater (option)
This equipment serves as a starting aid at temperatures below –5 °C and is located in the engine compartment, on the left in driving direction. Oil preheater (option) The engine and hydraulic oil is heated by means of heating elements with a capacity of 750 W in the engine oil pan and in the hydraulic oil tank, according to the gravity principle (warm oil rises and is replaced by cold oil). The oil can only be thoroughly warmed up to service temperature if the oil preheater is connected over a longer period of time – preferably over night. ☞ Connect the oil preheater as follows: • Park the machine near a 220 V socket • First connect the special cable (supplied with the machine) with the machine socket, then • Insert the plug into the 220 V socket
☞ Before starting the engine: • Remove the plug from the 220 V socket • Unplug the special cable from the machine socket • Close the engine cover
Important! The oil preheater (option) reduces pollutant emissions during the warm-up phase by up to 60 %, saving fuel at the same time.
Fuel preheater (option)
86 A B
We recommend switching on the fuel preheater (option) at temperatures below 10 °C. The fuel preheater prevents paraffin crystals forming, which otherwise clog the fuel filter at low temperatures. The switch is located on the right in the switch console ☞ Press switch 86 to position B
➥ The fuel preheater is switched on ☞ Press switch 86 to position A ➥ The fuel preheater is switched off
Important! Fig. 38: Switch for fuel preheater (option)
A heating element in the fuel line between the tank and the fuel prefilter is automatically switched on by a temperature sensor at temperatures below 45 °C, and switched off at temperatures over 50 °C. • The telltale in the switch comes on when the fuel is being preheated
