CAUTION
• As the pressure in the air tank increases
due to the pressure characteristic of the
pressure-reduction valve, the pressure can
vary from the set supply pressure by as
much as 2 bar.
Turn the pressure-reduction valve's adjust-
ment handle counterclockwise once to re-
duce the pressure and then proceed to the
adjustment while increasing the pressure
by turning the adjusting hand clockwise.
6. Make sure that the compression opera-
tion is automatically stopped in 6 to 7
minutes. Except when the power-saving
operation in Silent mode is turned on,
auxiliary tank is connected or voltage
drop occurred, since these extends the
operating hours.
7. Wait for 5 minutes after the operation is
stopped to confirm that there are no ab-
normal noises or air leakages and that
the compressor does not restart.
STOP
Operation is resumed
8. Discharge the compressed air by open-
ing the drain cock somewhat. Make sure
that the operation is resumed due to a de-
crease in the pressure.
9. Close the drain cock and turn the power
off while the compression operation is
turned on to make sure that these actions
stop the machine from operating.
10. Turn the adjustment handle (in 2 loca-
tions) of the pressure-reduction valve
counterclockwise to make sure that this
turning moves the pressure gauge point-
er downward at both locations. (You may
hear sounds due to air leaking but it does
not mean there is a failure.)
