GEERAL IFORMATIO
This machine has been designed and built ado ting the state of the art technologies, and with res ect of the Euro ean
Laws for machine tools.
Notwithstanding what above, it is im licit that working underestimating or forgetting the dangers related to this kind of
machine can generate, the o erator could cause serious injuries to him/herself.
Therefore, the o erator should carefully read the entire instruction manual, and res ect strictly what rescribed in it.
This symbol indicates that the aragra h contains im ortant information concerning
safety and injuries reventions
In articular, lease ay attention to the following suggestions:
 Keep always your working area clean.
 Avoid to keep in your working area pieces of material, chips, cans, or other things which could reduce the possi-
bility of movement to the operator or even generate risks of injury.
 Be always cautious using the machine, because, even if it is protected in every dangerous spot, it can be a dan-
gerous equipment, and thus it has to be use being particularly careful and aware.
 Give immediately notice to your supervisor if the machine needs to be maintained or serviced, even if the prob-
lem is caused by inexperience. An incorrect use of the machine can be dangerous and can cause injuries.
 Do not try to repair the problem if you are not sure of what caused it.
 ever service or maintain the machine when it is running. Always turn it off.
 ever leave the machine working without respecting the safety rules or removing the safety devices.
 Remove electrical power when the machine is not working.
 Always wear protective cloths, especially when replacing the blade.
 ever do anything imprudent.
 ever touch the unprotected part of the blade.
 ever cut any piece shorter than the shortest possible length.
 ever start cutting if the material is not firmly clamped by the vises.
 Move the material only if the cutting bridge is completely up.

2.1 M AI COSTRUCTIVE CHARACTERISTICS .
The machine uses:
• Band s eed readout
• Metered feed control.
• Band wheel drive with AC inverter and worm gear.
• Hydraulic guide arm.
• Carbide faced saw guides with large diameter lead in rollers on both guide arms.
• Hardened, ground, anti-wear steel lates on all work clam ing surfaces.
• Ground, hardened and hard-chrome lated guide columns.
• Power driven band cleaning brush.
• Hydraulic band tension.
• Recirculating, coolant system, um 400/50/3, a lied through nozzle.
• Band wheel door interlocks.
• Blade guards.
The saw is built to work in semi-automatic.
2.2. B LADE SPEED
The blade s eed is controlled by an AC motor and a variable frequency drive, which allow to regulate the blade s eed
within a range of 20- 80 m/1’. Therefore the machine can cut both hard steels and aluminum. A digital reader constantly
shows the blade s eed .
2.5. V ISES
Vises are hydraulic. The jaws are hardened
