Inspections and Maintenance
Note:
Additives which are used to prevent precipitation of paraffin crystals have a purely
preventative effect. They can not dissolve the paraffin crystals once they have
been precipitated.
Always carry a spare fuel fine filter in the vehicle so that you can replace it quickly if
it becomes blocked in any way (for example, by paraffin crystals).
Always preferably fill up in the evenings to prevent condensation (especially in
winter).
CAB HEATER
If necessary, install a separate fuel tank for the cab heater.
If the tank has been filled up with winter diesel oil because of a cold weather period
or a trip to a colder country, allow the cab heater to run on the new fuel for half an
hour to ensure that all the old fuel has been used up.
The above recommendations apply for both air and water heating and for all vehicle
types.
WINDSCREEN WASHER RESERVOIR
- When topping-up, it is advisable to add a cleaner to the water in the windscreen
washer reservoir.
- During the winter period, add screenwash antifreeze.
