Manual mode operation, cutting of extreme pipe diameters.
Observe the following procedure when cutting pipes of diameters bigger
than 360 mm with ARG 380 and 450 mm with ARG 500.
Procedure:
• Adjust the lower position limit switch so that X corresponds
with ARG 380 = 210 mm and with ARG 500 = 270 mm (see chapter 5.4).
• Using the BAND SAW BLADE EMERGENCY MOVEMENT push-but-
ton, lift the band saw blade to the maximal upper position.
• Insert a workpiece in the vice and clamp it (see chapter 5.1.1.).
• Switch on the band saw blade via the BAND SAW BLADE START push-
button. Switch on the descent via the START switch.
• When the workpiece cut is finished, the machine will switch off the band
saw blade and the band saw blade descent in the set lower end position.
When 1 piece or 2 pieces of pipes of extreme diameters are to be cut, it is
not necessary to set the lower limit switch. It is necessary to monitor the
cutting process of the material and to switch off both the band saw blade
and the descent via the BAND SAW BLADE STOP push-button immedi-
ately after the cut has been finished. A failure to do so would mean danger
of collision with the upper part of such an extreme material because the
band saw blade descent will not switch off automatically in the lower posi-
tion.
ATTENTION:
In case of resetting the limit switch, set it to the original X
value before switching off the machine (ARG 380 = 510 mm, ARG 500 =
620 mm) and leave the band saw blade in the lower position at the mecha-
nical stop. Otherwise, there is a risk of destruction of the limit switch.

In
AUT
mode - the automatic cycle is started: workpiece clamping, saw blade drive start, switching on the coolant pump, band saw head
feed to the cutting position, band saw head ascending to the set position, switching off the saw blade drive and the coolant pump, ope-
ning the vice.
In
MANUAL
mode, the band saw blade begins to descend with a rate set on the control valve, if the vice is clamped.
START
The cutting speed is stepless adjustable with the saw blade speed controller (via the frequency converter) on the control board arranged
on the band saw base.
The selected value within the range between
15(20) - 90 m/min is continuously displayed.

The MAXIMUM OPENING OF VICE serves to open the vice gripping jaws to the maximum. As long as the button is pressed, the
moving jaw moves away from the fixed jaw.
MAXIMUM OPENING OF VICE
only ARG 380 Plus S.A.F., ARG 500 Plus S.A.F.
The BAND SAW EMERGENCY MOVEMENT button has three functions. While a cut is being performed, it enables the raising the
band saw head with the arrow up and momentarily lift the band.
In case of failure - Broken saw blade (the signal lamp between the arrows is blinking), the band saw head can be set to an arbitrary posi-
tion by the button arrow up/down. In case of a machine failure, the other machine functions are locked.
In manual mode, it enables setting of the band saw blade ascent depending on the workpiece.
