Fuel
• Only use commercially available brand-name
diesel fuel with a sulfur content of less than
0.5%.
• Use only winter diesel fuel in winter to prevent
line connections becoming blocked through
paraffin deposits. At very low temperatures,
troublesome deposits may also occur when
winter diesel is used.
• If only summer diesel is available, or if winter
diesel must be used at very low temperatures,
we recommend the addition of petroleum (fig.
36) or additives.
These mixtures should only be used
temporarily, never for longer periods.
Only mix the components in the tank!
First fill the required quantity of
petroleum and then add the diesel fuel.
Flow improvement agents are to be
selected according to the specifications
of your fuel supplier.
Petrol shall not be added.
Danger of explosion!
