Before assembling the new blade, clean carefully the pulleys and the blade-guide.
Every time the blade is replaced, we suggest to remove the higher pulley and to
clean carefully the machine. When the pulley is removed, check the conditions of
the tight-bearings. If they are noising, replace them.

Stretch the blade rotating the knob in position "A" (Fig. 7.6.2).

Check the positioning of the blade on the pulleys:
the blade must lean on the pulleys, except for the sharp part that must jut out of
the pulley. See picture 7.6.3.
- Rotate by hands the pulleys and check the right positioning of the blade.

Close casing "1" and lock it by knobs "3".
