TROUBLESHOOTING
SYMPTOMS THAT ARE NOT
MALFUNCTIONS
The symptoms listed below are not
malfunctions.
• The lift arms go up or stop by themselves
at the stroke end, when the bucket
operation is performed at the same time as
the lowering of the lift arms.
• The travel motor produces noise when
stopped suddenly from its high speed
traveling.
• The control valve produces noise if
excessive force is applied to the working
equipment or when it moved to the stroke
end.
• It becomes less easy to operate the
machine when an attachment weighing
more than a standard bucket is installed.
• In some cases smoke may be emitted from
the tail pipe while the DPF regeneration is
being performed. This is not a failure; it is
due to burning of the particulate matter
(PM).
• In some cases the noise associated with
the DPF regeneration operation or cancel
operation may change; this is not a failure.
