Consumables 4.2 Fuel Permissible fuels The following fuel specifications are permissib- le: z Diesel fuels according to DIN EN 590 z US diesel fuel according to ASTM D 975 Grade-No.1-D and 2-D z Japanese diesel fuel JIS K 2204 Grade 1 Fuel and Grade 2 fuel, with lubricating pro- perties according to diesel fuel EN 590 (HF- FR max. 460 micrometer according to EN ISO 12156) Commercially available diesel fuels with a sul- phur content below 0.5%. If the sulphur content is higher, the lubricating oil change intervals must be reduced ( 27 ) If other fuels are used which do not meet the requirements of the operating manual, the war- ranty will be voided.
The certification measurements to satisfy the legal emission limits are performed with the test fuels defined by law. These correspond to the diesel fuels according to EN 590 and ASTM D 975 described in this operating manu- al. No emission values are guaranteed with the other fuels described in this operating manual. (generally offered by petrol stations in good time before the cold season begins). z Paraffin must be added below -20 °C. Ne- cessary mixing ratios according to the dia- gram opposite. z For Arctic climate zones up to - 44 °C, spe- cial diesel fuels can be used. If Summer diesel fuel has to be used below 0 °C, up to 30% paraffin can be mixed according to the diagram opposite.
Generally, sufficient resistance to cold can also be achieved by adding a flow ameliorant.

Fill with the appropriate amount of paraffin first, then add the diesel fuel. Normal and high grade fuels may not be mi- xed. At low ambient temperatures paraffin dischar- ges can lead to blockages in the fuel system and cause operating faults. Use winter fuel at outside temperatures below 0 °C (to -20 °C) 24
