8. Maintenance
Maintenance and inspections are very important in order to keep good performance for a
long time.
It is strongly recommended that the customers conduct daily inspections and maintenance.
When you conduct overall inspection, it is necessary to replace consumables such as
compressor. Please contact us.
8.1 Daily Inspections and Maintenance
1) Abnormal sound and vibration
Every time the equipment is used, check if it has noise large and different from
usual, or large vibrations. If abnormal sound or vibration is observed, shut down
the equipment immediately
2) Cleaning and replacing intake air filter
It is extremely important to clean the intake air filter attached to the compressor.
The compressor performance will be deteriorated if this filter is clogged. Frequent
cleaning is encouraged especially in places where dust is observed. When the
clog cannot be removed by cleaning, replace the filter. Please contact us for the
necessary parts.
3) Others
When cleaning intake air filter, inspect with your eyes whether couplings, piping,
bolts, nuts or screws are firm enough. Tighten when they are loose.
8.2 Total Inspection
The life of the compressor is one year if it runs continuously. It is necessary to
replace compressor, and inspect the adsorber deterioration, piping, couplings, or
solenoid valves. If the equipment has not been running for a long time, contact us for
the total inspection once a year. If the running time is short, we conduct only
performance check for the compressor.
