3. MACHINE OPERATING PROCE-
DURE
Inspection and checkup prior to oper-
ation
• Prior to use, check the bolts and nuts for
loosening and the parts for missing one.
• The power supply used must AC 115V 15 A
and provided with a circuit breaker. Allow-
able source voltage range is +/-10%.
• Gauge and length of the extension cord or
drum cord used must be AWG 12 minimum
and 50 ft. (15m) maximum, respectively.
And the cord must be fully drawn out when
used.
• Make sure the machine is installed in the
right direction when using it.
∗ Use the machine in compliance with the in-
structions provided in "SAFTY INSTRUC-
TIONS" on page 6.
∗ Pressure values in the description do not in-
clude the error in reading the pressure gauge.
1. After turning off the machine power
switch, connect the power plug to the
outlet.
• When using an extension cord or drum
cord, make sure its effective gauge and
length are AWG 12minimum and 50 ft.
(15m) maximum, respectively.
2. (Fig.C,D) Turn the power switch on while
maintaining the drain cock fully open.
The buzzer sounds with a beep at the
same time.
• For buzzer sounding patterns, see
page 17.
3. Make sure that the motor starts to run
and the air is leaking from the drain cock
when the drain cock is open.
4. (Fig.E) Close the drain cock and make
sure no air is leaking from the cock.
5. Turn the adjustment handle (in 2 loca-
tions) of the pressure-reduction valve ful-
ly clockwise until you cannot move it
anymore and make sure that the above
operation moves the pressure gauge
pointer (Fig.F) at both locations.
• 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 29 psi (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 Quiet 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.
8. (Fig.D) Discharge the compressed air by
opening the drain cock somewhat. Make
sure that the operation is resumed due to
a decrease in the pressure.
9. (Fig.E,G) Close the drain cock and turn
the power off while the compression op-
eration is turned on to make sure that
these actions stop the machine from op-
erating.
10. (Fig.H) Turn the adjustment handle (in 2
locations) of the pressure-reduction
valve counterclockwise to make sure that
this turning moves the pressure gauge
pointer downward at both locations. (You
may hear sounds due to air leaking but it
does not mean there is a failure.)
