EXPLANATION OF COMPONENTS
REMARK
After switch F6 is pressed in step 6., the screen shown in
the figure may be displayed. This indicates that the opera-
tions in steps 1 to 4 were not performed correctly or there
is trouble other than KDPF soot accumulation abnormality.
After checking that the engine is running normal, the park-
ing brake lever and work equipment lock lever are in
LOCK position (L) and the fuel control dial is set to Low
idle (MIN) position, repeat the procedure from step 6.
If the manual stationary regeneration still cannot be per-
formed, return to the standard screen, press switch F5 to
check the contents of other occurring troubles, stop the
work and perform inspection and maintenance.
If hydraulic fan reverse operation is performed while the af-
tertreatment devices regeneration pilot lamp or the KDPF
soot accumulation caution lamp is lit, the accumulated soot
may not be burnt sufficiently and the filtering function may
not be improved. Wait until the aftertreatment devices re-
generation pilot lamp or the KDPF soot accumulation cau-
tion lamp goes out, and then perform hydraulic fan reverse
operation.
