Changing Fuel Filter - Volvo FM Handbook

536 Maintenance
• Use up most of the fuel in the tank before changing
to a new fuel. This is to avoid bacteria spreading in
the tank.
• If the vehicle is not used for a period of at least 4
weeks, the system should be flushed through with
diesel by driving on at least one full tank.
• Engine/cab heaters are not adapted to run on
FAME, so a separate diesel tank must be fitted.
Engine/cab heaters shall only use diesel in
accordance with EN590.
• FAME is aggressive to paint and certain types of
rubber and plastic. If FAME comes into contact
with a painted surface, wash it off immediately and
thoroughly to avoid damage.
Used oil
Used oil and two-stroke oil considerably shorten the
service life of the injection equipment. In addition, the
exhaust emissions increase if these oils are used.
Fuel at airports and military operations
It is normal practice that trucks at airports and in
military operations use aircraft jet fuel or various
military grades of diesel. It is important to monitor the
specifications of the fuel in question and it is essential
to find out correct data about all the additives that have
been put into the fuel in question. If you have a
question, contact Volvo Trucks!

Changing fuel filter

Change the fuel filter when doing an oil change, or as
required, for example if:
• the fuel pressure drops
• the power output decreases
• the fuel quality is uneven
• the symbol for blocked fuel filter starts to light
1 Clean the filter bracket thoroughly
Note!
It is not permissible to add used oil
or two-stroke oil to the fuel tank.
Caution!
Take care not to allow fuel to run
over and damage electrical
components.
