13.6 Blade replacement
The diamond blade is made of material that may be damaged
when subject to high temperatures, and therefore must be
cooled during the work phases.
To replace the blade, proceed as follows:
1.Block axial movement of the cutting head by means of the
handwheels (ref. O fig. 7).
2. Disassemble the front guard (ref.D fig.4).
3. Loosen the locknut by rotating clockwise (left thread), using
a 19 mm wrench.
4. Move the cutting head forward slightly and incline to remove
the blade from its seat.
5 . Ensure that there are no foreign objects between the fixing
flange and diamond blade. During disassembly, avoid use of
tools that could dent or deform the flange.
6 . Insert the new blade proceeding in reverse order of the
operation described at point 4. Take special care to ensure
correct direction of rotation of the diamond blade.
7. Tighten the blade locknut fully down by rotating
anticlockwise (left thread), to a torque of 40 Nm.
13.7 Cleaning the cooling water supply circuit
At regular intervals (or when the flow rate of the blade cooling
water is reduced) clean the cooling water supply circuit. To do
this, disassemble the delivery nozzle (ref. S fig. 4) located
inside the blade guard and clean in water.
Periodically clean the cooling water delivery line between the
pump and valve, (ref.V fig. 7) and blade guard using water.
