6.2.10 Wheels
Made using cast iron G26, and lathe machined. They are fastened as follow :
• the idler wheel is fastened on the band tension assembly, and it turns on ball bearings ;
• the band drive wheel is fastened using a collect locking 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 (Exhibit A07)
The machine mounts a self-cooling AC electric motor. On the shaft there is a three throats pulley, on which there are 3 V-
belts to connect motor and reducer

YDRAULIC POWER UNIT
The power unit has a double location inside the machine frame. Underneath the infeed roller table there is the oil reservoir,
and under the outfeed roller table there are all the solenoid valves. The power unit is made by :
Pos.
6.3.1
Motor-pump assembly
6.3.2
Oil reservoir
6.3.3
Solenoid valves
6.3.1 Motor-pump assembly
Electrical motor and pump are connected by an elastic coupling.
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 plug which allows to refill the reservoir. The hydraulic system has 2 filters :
• a 250 micron 45 litres 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 tri-
chloroethylene and dried blowing air.
6.3.3 Solenoid valves
The solenoid valves are mounted on blocks, and the control the hydraulic movements.
