10. CAUTIONS FOR A LONG TERM OPERATION SUSPENSION
CAUTION
● If the air compressor stops for a week or more without taking action described in this page, serious
damage for the airend may occur due to the lack of lubrication or airend internal rusting.
● Use unload stop button not only for long operation suspension but also for daily operation to prevent
the airend from the rusting.
● If the air compressor can’t be operated weekly, rust prevented action and periodical inspection is
required. Contact the local HITACHI distributor/master dealer or representative office for the detail.

■ How to perform the unload stop action with
lead-lag or multi unit control operation (option)
Unload stop button is ineffective when the operation
mode setting is NOT “Single”. (
3.3.5 󱦱)
Deactivate the lead-lag or multi unit control at once
and perform unload stop. When the air compressor is
restarted, set the operation setting to required mode.
① If the compressor is not to be used for a week or
more, be sure to press the UNLOAD STOP button on
the instrument panel.
The compressor then unloads for 5 minutes and
automatically stops when the airend and the piping
are dry.
② To prevent the inside of airend from rusting, press the
UNLOAD STOP button and dry the compressor for 5
- 10 minutes a week.
③ Be sure to turn off the power if the compressor is not
to be used for an extended period of time.
If unloading is executed before the compressor is stopped,
moisture will be removed from the second-stage air end.
To prevent the second-stage air end from rusting during a
long-time suspension, it is effective to dry the inside of the
air end before stopping the compressor..
