ENGINE OIL REQUIREMENTS
Use only API CJ-4 engine oil. Use of Kubota OEM fi lters is recommended. The engine oil and
fi lter should be changed after the fi rst 50 hours of operation. Thereafter, the recommended
engine oil service interval is 250 hours.
EXHAUST SYSTEM REGENERATION
The exhaust system diesel particulate fi lter (DPF) gets continuously loaded with soot from
exhaust gas and will continuously do passive regeneration if the exhaust temperature is
above 572°F (300° C). The engine will periodically require an active regeneration to further
raise the exhaust temperatures and clean soot from the DPF. The Engine ECU calculates
when active regeneration needs to take place. This is determined based fuel consumption,
elapsed time, engine operating conditions and the delta pressure sensor signal. This can
occur without operator intervention while sweeping. The high exhaust temperature icon will
illuminate to indicate cleaning is active.
High Exhaust Temperature Icon
If operator initiated regeneration is needed, the Exhaust Filter Indicator will illuminate along
with a diagnostic trouble code message. If the operator initiated regeneration is not completed,
additional engine fault codes and engine derate will occur. See the Controls Section for
information on initiating regeneration.
