6.2.2 Guiding columns
The columns guide vertically the cutting bridge movement. They are made with chrome bars, hardened and grinded.
6.2.3 Columns connection
Made using a Fe37 steel late, the columns connection connects and makes the guiding columns sturdier. It is fastened to
the columns through two bolts.
6.2.4 Lifting cylinder
This is an hydraulic cylinder, with chrome rod and la ed cylinder. The lifting cylinder is a double effect cylinder. The cy-
linder head is attached to the cutting head, and the end head is fastened to the machine base frame.
6.2.5 Blade tension assembly
The C-M utilize an automatic band tension system. The ro er band tension is assured by the cylinder.
The system has been designed to guarantee a ro er tensioning of the band. (see 15.4 Band re lacement).
6.2.6 Band drive assembly
The band is owered by an AC motor which automatically regulates the cutting s eed. The motor is directly flanged on
the s eed reducer: this a lication reduces vibration while roviding best ossible torque. On the other end of the reducer
there is the drive wheel, that is fastened to the reducer.
6.2.7 Band brush assembly
A band brush is owered by an hydraulic motor, and it cleans the teeth removing the chi s.
6.2.8 Left and right band guides.
The band guides have to straighten the blade coming out the wheel, and kee it vertical hel ing the blade insertion be-
tween the inserts.
Left guide arm : Moves horizontally on guides machined on the bridge, and it is moved by the movement of the vise.
Right guide arm : Fixed on the cutting bridge. It su orts the cutting servo control.
Both the guide arms have carbide inserts.
6.2.1 Wheels
They are mounted as follow :
 the idler wheel is mounted on the band tension assembly and it turns on ball bearings ;
 the band drive wheel is mounted on the reducer shaft.
The wheels diameter is larger then the maximum material height that can be cut by the saw..
6.2.11 Band drive motor
The machine mounts a 15Kw, AC electric motor.

6.3.1 Motor-pump assembly
Electrical motor and um are connected by an elastic cou ling.
6.3.2 Oil reservoir
It is in the machine frame, and it has a maximum and a minimum level indicators, and a suction filter. On the left side of
the infeed roller table there is a lug which allows to refill the reservoir. The hydraulic system has 2 filters :
 a 250 micron 45 liters suction filter
 a 60 micron 45 liters outflow filter
These two filters have to be removed when changing the oil for the first time (after 500 working hours), washed using
trichloroethane and dried blowing air.
6.3.3 Solenoid valves
The solenoid valves are mounted on blocks, and the control the hydraulic movements.

7. MACHIE PROTECTIOS
This machine is entirely rotected where it can be dangerous. Des ite of this, there are some arts that cannot be ro-
tected, and where the o erator must never work. The biggest of these arts is where the blade touches material.
There is a sticker close to every art which is not com letely safe, to show to the o erator that he should be extremely
conscious.
8. HOW TO MOVE THE MACHIE
This machine, when installed and fastened to the ground must be considered a fix equi ment.
If it is necessary to move the machine or arts of it (because of maintenance or service), the o erator must use a crank or a
fork lift, or a lighter lifter with regards of the weight of the art that have to be lifted.
9. HOW TO ISTALL THE MACHIE
The machine can be installed by :
 the manufacturer/distributor ;
 the customer ;
The machine is shi ed com letely mounted.
Moving the machine is one of the moment the risk of injuries is higher, thus it is im ortant to make sure that :
 Every o erator wears the necessary safety equi ment.
 The lifting equi ment must be enough big to lift the machine. Always use only one lifting equi ment to lift the ma-
chine, never combine more then one.
 Do not use a lift fork if the length and width of the forks are inadequate to lift the machine.
 If using a crank, use metallic ro es and be sure they can su ort the weight of the machine. Put strong cartoon or
wood between the ro es and the machine. Never leave the ro es slide freely on the machine body.
 Do not use metallic ro es if they show wear areas.
 Lift the machine slowly so to have enough time to adjust the lifting if necessary or to avoid obstacles.
 In the lifting area there should be enough eo le to move safely the machine, and do not allow anyone else to stay in
the lifting area during such o eration.
 Be sure that every movable art is well fastened to the machine. Remove or secure every art which falling can be
dangerous for the eo le in the work area.
 Move the machine aying attention to the surrounding environment. Be extremely cautious so to avoid hitting any-
one or anything.
 Moving the machine, stay as close as you can to the ground to avoid that a ro e brake could generate dangers or se-
rious machine breaks.
 If necessary, ut ieces of wood under the machine base before utting it down.
