6.5.2 - MAINTENANCE AND ASSISTANCE FOR THE PARTICULATE FILTER
In addition to particulates, ash also accumulates in the SF. This is mainly due to metal additives
contained in lubricating oil. A small quantity of lubricating oil is burned in the combustion
chamber, which is then collected in the SF together with the combustion gases. This small
amount of metallic ash cannot be burned in the DPF. It therefore builds up over time and causes
the engine to lose pressure, as well as having other negative effects on it. In this case, the DPF
has to be cleaned. McConnel recommends performing maintenance every 6000 working hours.
Make sure that you use specific fuel and lubricating oil so that the DPF can function correctly.
Use a type of diesel that has a very low sulphur content ≤ 15 ppm. If you use a fuel other than
the one specified, it might prevent the DPF from being regenerated properly by generating an
excessive quantity of particulates. This results in an excessive fuel consumption and the
deterioration of the engine (reduced performance) due to the continuous activation of the
regeneration process.
It is also recommended to use a lubricating oil with a low carbon content, otherwise an
excessive amount of ash will build-up in the DPF in a short time. This results in an excessive
fuel consumption and the deterioration of the engine (reduced performance) due to the
continuous activation of the regeneration process. It will also mean that maintenance of the SF
will have to be carried out earlier.
The owner of the RC40 is responsible for carrying out the maintenance described in the service
booklet. The exhaust filter warning indicator on the display or the diagnostic codes indicate
when the ash needs to be removed from the particulate filter.
The removal of the ashes from the particulate filter must be carried out by specialised personnel
and in complete safety. Do not remove the ashes using water or other chemical substances. If
these methods are used to remove the ash, there is a risk of damaging the material that secures
the particulate filter inside the casing. This may loosen the cartridge inside the casing and make
the particulate filter more susceptible to damage due to vibration.
The failure to respect the methods approved for the removal of the ashes could cause damage
to the DPF filter producing the potential annulment of the guarantee on the exhaust filter
emissions for diesel engines. Contact McConnel customer care for any servicing information
that may be required.
• The removal of ashes from the DPF filter must be done exclusively by a
qualified assistance provider.
• During the manipulation and cleaning of a DPF filter it is necessary to wear
personal protection equipment and protective clothing kept in hygienic and
reliable conditions.
• For advice, contact McConnel’s support service or a qualified service supplier.
