ADJUSTING CLEARANCE BETWEEN THE BLADE AND DRUM
To adjust the clearance between the blade and drum, proceed as follows:
• In the inner part of the base, loosen the screws A by using a 17

Once the desired clearance is obtained, block the screws A.
IMPORTANT: manually rotate the drum at least once before starting
the machine.
