MACHINE IN GENERAL
If even a minor fault is left intact and operation is continued, a fatal failure may be caused,
entailing a large sum of expenses and long hours of restoration.
Therefore when even a small trouble occurs, do not rely on your intuition and experience, but look
for the cause based on the troubleshooting principle and perform maintenance and adjustment to
prevent major failure from occurring. Keep in mind that a fault results from a combination of
different causes.
The following lists up commonly occurring faults and possible causes with this machine. For the
troubleshooting of the engine, refer to the coming troubleshooting and repair.
When carrying out troubleshooting, do not hurry to disassemble the components.
It will become impossible to find the cause of the problem.
Ask user or operator the following.
Was there any strange thing about machine before failure occurred?
Under what conditions did the failure occur?
Have any repairs been carried out before the failure?
Check before troubleshooting.
Check oil and fuel level.
Check for any external leakage of oil from components.
Check for loose or damage of wiring and connections.
