3. Machine operating procedure
Inspection and checkup prior to operation
WARNING
○
Prior to use, check the bolts and nuts for loosening
and the parts for missing one.
○
The power supply used must 230 VAC 10 A and
provided with a circuit breaker. Allowable source
voltage range is +/-10%.
○
Width and length of the extension cord or drum
cord used must be 2.5 mm
2
minimum and 20 m
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 instructions
provided in "SAFTY WARNINGS" on page 29.
•
Pressure values in the description do not include the
error in reading the pressure gauge.
(1) After turning o
ff
the machine power switch, connect
the earthing plug of the power plug to ground and then
connect the power plug to the outlet.
When using an extension cord or drum cord, make
sure its e
ff
ective cross section and length are 2.5 mm
2
minimum and 20 m maximum, respectively.
(2) Turn the power switch on while maintaining the drain
lever fully open.
(3) Make sure that the motor starts to run and the air is
leaking from the drain tube when the drain lever is
open.
(4) Close the drain cock and make sure no air is leaking
from the tube. (
Fig. 6
)
(5) Turn the adjustment handle (in 2 locations) of the
pressure-reduction valve fully clockwise until you
cannot move it anymore and make sure that the above
operation moves the pressure gauge pointer (upward)
at both locations.
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 adjustment handle
counterclockwise once to reduce the pressure and
then proceed to the adjustment while increasing the
pressure by turning the adjusting hand clockwise.
(6) Make sure that the compression operation is
automatically stopped in 6 to 7 minutes. Except when
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 con
fi
rm that there are no abnormal noises or air
leakages and that the compressor does not restart.
(8) Discharge the compressed air by opening the drain
lever somewhat. Make sure that the operation is
resumed due to a decrease in the pressure.
(9) Close the drain lever and turn the power o
ff
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 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.)
(
Fig. 7
)
(11) Open the drain lever to discharge all the compressed
air and water in the air tank.
If you found any abnormalities in the checkup or
inspection prior to the operation, send the machine to
your dealer or authorized service facility for inspection
or repair.
Operating procedure
Before operating the machine, be sure to carry out the
"Inspection and checkup prior to operation" described on
page 33.
(1) Fully open the drain lever and turn the power switch on.
After the operation has started, close the drain lever
tight to increase the pressure.
(2) After
con
fi
rming the operation has stopped due to the
increased pressure, turn the adjustment handle of
the pressure-reduction valve to adjust the operating
pressure of the nailer and pneumatic tool to the
appropriate level. When adjusting the pressure, turn
the pressure-reduction valve's adjustment handle
counterclockwise to set the pressure at a level lower
than the appropriate value by 2 bars once. Then
proceed to the adjustment while increasing the
pressure by turning the handle clockwise. (
Fig. 7
)
○
Make sure to start the adjustment at a level lower than
the appropriate pressure and continue the adjustment
while increasing the pressure from that level upward.
If you start the adjustment from a level higher than
the appropriate value, an error results between the
pressure gauge value and actually used pressure.
(Due to Characteristics of pressure-reduction valve
respectively)
○
2 pressure-reduction valves provided on this machine
allow you to connect HiKOKI high pressure tools and
the general-purpose nailer or pneumatic tool.
<Pressure-reduction valve H>
Allows connection and use of HiKOKI high pressure
tools (of operating pressure of 25 bars maximum)
<Pressure-reduction valve L>
Allows connection and use of the general-purpose
nailers or pneumatic tools (of operating pressure of 8
bars maximum)
WARNING
○
You must observe the speci
fi
ed operating air
pressure for the nailers and pneumatic tools.
Using a nailer or pneumatic tool without adjusting
the supply pressure with the reduction valve can
seriously degrade their performance, induce their
premature aging or damage them.
○
Using a nailer or pneumatic tool at an inappropriate
pressure level (at an unnecessary high pressure)
increases their air consumption, potentially degrading
their capability in continuous work. Be sure to use them
at the appropriate pressure.
(3) After you have
fi
nished with the adjustment of supply
pressure, you can start the operation by connecting the
air hose to the air outlet (air socket). (
Fig. 8
)
(4) Connect the high pressure hose to the high pressure
air hose for HiKOKI high pressure tools to the high
pressure air socket on the H side of the pressure-
reduction valve.
Connect the air hose for the general-purpose nailer to
the air socket on the L side of the pressure-reduction
valve.
The air socket is the one-touch type, allowing you to
connect the air plug to the air socket just by pushing in.
WARNING
Before connecting the air hose to this compressor,
make sure that the air hose and hose
fi
xture are
fi
rmly
secured.
