General

The information in this section has been compiled on the experiences gained through field
service operations and factory tests.
The failure signs, symptoms and causes are listed by the frequency of feedback from the service
technicians.
As the systems and failures are usually correlated as of the compressor nature, it is a must to
clearly understand the actual cause of the failure before attempting any repair or part
replacement.
It would be useful to perform a comprehensive visual check before taking any action for the
experienced problems.
A good monitoring of the failures would make it possible to prevent any possible damages to
occur in the course of repair works.
In particular:
•
Unless otherwise is stated, perform all the checks when the compressor power is completely
disconnected.
•
Check all the power connections for any possible loosening.
•
Check any parts and components that may be affected by short circuit or temperature.
•
Check any possible damages and loose points on the hoses, pipes and connections in the air
and oil circuits.
If the problem persists in spite of all actions taken as per this manual for any failure, please
contact our service department.
It is the most reliable action to apply to our authorized service stations for any
troubleshooting, maintenance and repair works for the safety of your compressor and
facility.
Any attempt without sound knowledge may create adverse effects, and result in
unnecessary shutdown of your plant facility and high cost damages.
