DESCRIPTION
The latest Tier 4/Stage IIIB legislation stipulates that any diesel engine over 50 horsepower must have an
engine system that reduces the harmful diesel emission that are discharged into the atmosphere.
There are many engine components that together perform this task, but whilst most of them function
automatically, the Diesel Particulate Filter (DPF) can need some operator input in order to keep it
maintained to a suitable standard.
WARNING
During some stages of the engines operation the temperature of the exhaust components and gases
can reach very high levels of up to 625°C. To prevent burns do not touch any of the exhaust
components and do not place any part of your body into the path of the exhaust gases. To prevent
fire, make sure that the engine area is kept clean of grass clippings and other flammable debris.
CAUTION
When operating either the LM3210 or the GM2810:
Always perform the machines required daily checks.
Do not allow the engine to idle for prolonged periods of time.
Always keep the engine bay area clean and make sure that grass clippings and other flammable
debris are not allowed to build up near the exhaust components.
Always use a clean and fresh 'Ultralow Sulphur' diesel fuel (below S15 ppm).
Always use the correct Low Ash engine oil (CJ-4 grade SAE10W-30).
Always check the Water Separator for water and drain if any is found.
Always service the engine in accordance with the recommended Kubota schedule.
THE IMPORTANCE OF PDF MAINTENANCE
A DPF needs to be kept clean in order for the engine to function correctly and reliably.
If simple operator maintenance is carried out on the DPF when the onboard display requested it, then
the DPF can have a service life of over 3,000 hours. But if service requests are ignored then soot levels
will continue to accumulate until the DPF requires a specialist repair or even part replacement.
