SAR 440 SA GDS
DESCRIPTION OF THE
OPERATING CYCLE
Before operating, all the main organs of the machine must be
set in optimum conditions (see the chapter on “Regulating the
machine”).

- Activate the hand wheel of the gear and set the speed control
to suit the characteristics of the material to be cut. ( do not
regulate when the motor is off ).
To regulate the desired speed refer to the plaque .
- In case of a wrong manoeuvre or to stop the cutting cycle,
press the STOP button ( 10 ).
- At the end of the cutting cycle, the sawframe will stop in the
inferior position. Rotate the selector ( 5 ) to activate the lifting of
the sawframe.
- Turn selector ( 9 ) to open the vice.
ATTENTION:
- The cutting cycle can be executed even if the selector ( 9 ) has
been switched for the open vice.
In fact, as you press START ( 3 ) the vice will close automatically.
To open the vice again you will have to turn the selector ( 9 )
first to close the vice and then to open the vice.
- Once the cut has been executed the hydraulic pump will keep
running for 20 seconds.
ATTENTION: Soon after the automatic shut off of the hydraulic
pump, press the button ( 4 ) to open the vice automatically if
the selector ( 9 ) was switched to vice open during the cutting
phase.
Note: It is recommend not to use the saw to its maximum
capacity for the first 50 working hours.
It is absolutely forbidden to approach the hands to
the cutting area.
Note: for a proper lubrication and cooling during the cut, we
recommend to use a mixture of 9 parts of water and one of oil.
6.1 - Getting started
DESCRIPTION OF THE CUTTING PROCESS:
- Start the cutting cycle
- Automatic closure of the vice;
- Lowering of the sawframe ( blade );
- Lifting of the sawframe ( using selector );
- Opening of the vice.
PRELIMINARY OPERATIONS:
- Ensure that the machine is not on emergency stop; in which case
free the red, mushroom shaped, button ( 1 ) on the panel of com-
mands.
- Rotate the blade tension handwheel ( 8 ) until the blade tension
pressure reaches 160 Bars.
- Rotate the main switch ( 2 ) in position 1.
- Press the illuminated button ( 3 ) and ensure that the relative
light is lit.
- Rotate the selector ( 5 ) to activate the lifting of the sawframe.
N.B.: if the lifting process does not occur, invert the electric
alimentation phase ( this operation is only to be done during in-
stallation ).
Service pressure of the hydraulic unit should be approx. 50
BAR.
WARNING: always ensure that the vice is positioned to the
extreme left or right of the counter vice to avoid accidental
contact with the structure of the sawframe.
- Turn selector ( 9 ) to open the vice.
- Position the vice according to the dimension of the material to
cut.
- Put the material to be cut in the vice, and approach the vice
jaw up to 3 - 4 mm with the handwheel.
- Ensuring that the latch is in place on the rack.
- Load the material to cut at the required cutting length and turn
the selector ( 9 ) to lock the material in the vice.
- Bring the mobile blade guiding arm as close as possible to
the object to be cut.
- Ensure that the cutting index correspond with the inclination
desired and that the device is blocked.
- Before starting the cutting process, it is advisable to advance
the blade to more or less 10 mm from the object to be cut,
pressing, if necessary, selector ( 5 ).
- Press regulator ( 6 ) to the ideal cutting speed to suit the
characteristics of the material. It is recommend that one always
start off slowly, increasing the speed if necessary.
- Press button ( 4 ) to initiate the cutting cycle: control that the
blade turns in the correct direction and that the cooling liquid
flows sufficiently.
